Number Question Response

1 Does the Government want the aerosol capability to be removable from the system? Is there a vapor only mode desired?

The aerosol capability is not required to be removed from the AVCAD. See Performance Specification Objective Paragraph 3.1.1.l for vapor only detection.

2 Would it be acceptable for a system to have dual inlets, one for aerosol and one for vapors?

Yes.

3 The primary aerosol capability should be a TRL 6 and the alternate can be TRL 4. Is that correct?

Correct.

4 What assumptions should the offeror make with costing the aerosol capability for the options? Should the offeror assume the primary capability is selected?

The offeror should base cost using one aerosol approach of their choice, and should discuss as the primary aerosol capability in their proposal.

5 In general, the aerosol capability and requirement for transport of low vapor pressure chemicals introduces size, weight, and power challenges to the system, yet the specifications do not seem to account for these additional challenges.

Requirements that adversely impact overall system performance should be a topic at the PDR and CDR for an informed collaborative decision.

6 The battery life requirement will likely be difficult to meet with the aerosol capability fully engaged. Would the Government consider a compromise where power related specifications were demonstrated in a degraded mode without the aerosol capability engaged?

Requirements that adversely impact overall system performance should be a topic at the PDR and CDR for an informed collaborative decision.

1 Is JPEO's intent to issue AVCAD requirements as a Task Order under the JE RDAP ID/IQ?

AVCAD requirements will be issued as a standalone RFP.

2 If JPEO is now isssuing AVCAD under the JE RDAP ID/IQ, does JPEO intend to issue the TO as Full & Open?

AVCAD requirements will be issued as a full and open RFP.

3 Does JPEO plan to conduct a downselect if multiple offerors are awarded, or will each awarded offeror have EMD, LRIP, and FRP options in their base contract that the JPEO will choose to either exercise or not?

There will be no "down-select" or future competition between contractors if two contractors are selected for award. The Government's intent is to award the EMD options for both contracts. After that point, if successful EMD test results are obtained under both contracts, the LRIP and FRP options may be exercised under both contracts. In this senario (e.g. two contract awards and successful EMD tests for both contractors), the Government reserves the right to either obtain all LRIP and FRP production items from a single contractor or to divide production options between contractors based based on (i) price, (ii) sustainment cost, (iii) performance against the PSPEC and any mission requirments to maintain multiple sources of supply. The Government intends to evaluation and exercise options that are in the best interest of the Government inaccordance with the FAR

17.207 considerations. Contractors may be asked to submit revised pricing for LRIP and FRP options within established ceilings to support the Government's decision.

4 What is the basis the JPEO plans to use to decide whether or not to execute contract options?

See above answer.

5 Will this selection criteria be further definded within Section L and Section M?

No. See above answer. There is no "selection criteria" for exercising options. There is a reasonable likelihood that any given option may be awarded and the Government will use the procedures in FAR 17.207 to determine if and when to exercise options.

6 Will the JPEO consider releasing the AVCAD TEMP along with RFP to facilitate offeror's preparation for EMD testing events given the aggressive schedule?

No, the TEMP will never be released to the contractors. The RFP contains sufficient information for planning purposes. A detailed test schedule will be available post-contract award.

7 Will the JPEO consider releasing the schedule for CDRL deliverables in advance, in particular those due with RFP in efforts to allow offerors to plan resources accordingly for the proposal submission?

CDRL DD FORM 1423-2 will be released with the final RFP.

8 How does the Government want test reports from programs such at M3TD and the NGCD TD phase submitted? Should the unclassified versions of the test reports be submitted and the key code provided as a classified document, or should full classified test reports with all agents identified be submitted through a separate method (i.e., other than the web submission portal)?

The offeror may do either. Please refer to L.1.5, L.4.1.3.1 and L.4.1.3.2.

9 Does the Government anticipate that the FRP bid will be firm? Would the Government consider the use of ROMs at this time for the later options?

ROMs are not acceptable. The price structure of FPI(S) means these prices may be re-negotiated prior to option exercise.

10 When does the Government anticipate Option 2 will begin- concurrent with the base or with Option 1?

Several of the activities would need to be started early to have the best chance to influence the final design.

The Government anticipates awarding Option 2 with the base.

11 When will the Government provide the draft of all sections of the anticipated solicitation, including terms, conditions, special clauses, attachment etc…., for contractor evaluation and adequate consideration of compliance, and the impact to scope to meet program requirements?

The remaining sections will be provided with the final solicitation.

General page 1 of 1 number Question Response

1 Performance Specification Paragraph 1. 3.3.1 Training item c:

Provide the capability to remotely activate alarms and malfunction signals for training purposes while networked, connected to the NBCRV Support Procession Group, {or connected to the Remote Alarm}.

Please define or provide reference for NBCRV Support Procession Group.

This section has been revised as follows:

"Provide the capability to remotely activate alarms and malfunction signals for training purposes while networked, connected to the NBCRV Sensor Processing Group, {or connected to the Remote Alarm}.

The Sensor Processing Group (SPG) is a software-based program where individual sensors can provide data via laptop computers that is ultimately processed for use in NBC reports.

2 Performance Specification Requirement 3.2.4.e requires Data in transit encryption, further definition would be appreciated in the implementation. The reference document speaks more to cryptographic module, physical security etc., but doesn't define implementation of data in transit. For example does this requirement mean all communication via wired, wireless Ethernet, and remote alarm wireless coms need to be encrypted along with the download of the logs via sftp, usb drives or other methods?

Yes, any detector communication should be encrypted, including the remote alarm. The minimum security standard is FIPS 140-2, Level 2.

Downloaded data files, including spectra and log files, require encryption as described in NIST SP 800-111 "Guide to Storage Encryption Technologies for End User Devices" provided at this link: dx.doi.org/10.6028/NIST.SP.800-111

3 Performance Specification Requirement 3.1.4:

Does "the central 90% of the user population" mean 90th percentile female and 90th percentile male? MIL- STD-1472G Appendix B provides measurement for both 5th and 95th percentile male and female, but doesn't provide any measurement on 90th percentile on either male or female. DOD-HDBK-743A (13 February 1991) Military Handbook Anthropometry of U.S. Military Personnel provides measurements on wide range of percentile on both male and female, which includes 90th percentile. However, DOD-HDBK- 743A is not listed in Section 2.2.1 Specifications, standards, and handbooks. Can DOD-HDBK-743A Anthropometry measurements be used if the requirement is intended for 90th percentile male and female, instead of 5th percentile female and 95th percentile male?

The intention of the Government is to cover as wide a range of military personnel as possible. This section has been expanded to the 5th to 95th percentile male and female populations. The Government would not recommend using DOD-HDBK-743 at this time.

4 Performance Specification Requirement 3.3.3 Will AVCAD be operated while NBCRV is in motion or in stationary position? If both, please provide expected corresponding duty cycle of AVCAD being operated during NBCRV in motion and in stationary position

Both, the AVCAD will be employed while the NBCRV is both stationary and on-the-move. The on-the-move and stationary duty cycles are each approximately 50% of the total mission duration. A note has been added to this section.

5 Performance Specification Requirement 3.1.6.1.p & 3.1.6.2.i both reference wireless communication for the remote alarm and 3.2.4.h reference 802.11 wireless connectivity for the AVCAD system. How do these requirements fit with solicitation number W911SR-17-R-NGCD? Is AVCAD expected to use the chosen technology from the solicitation through a defined connection like USB or is the vendor expected to provide their own solution for these requirements?

Built-in 802.11 communication between the detector and remote alarm is required. The capability for the detector and remote alarm to interface with an external radio via the USB or 802.3 connections is also required for longer distance communications.

The specific radios are to be determined.

6 Performance Specification. Does the government intend for an alternate AVCAD configuration to support IPDS-LR replacement requirements (Section 3.2.5)? If so, what proportion of AVCAD systems are intended to support the IPDS-LR replacement requirement?

The Government would prefer the same detector unit configuration to support the IPDS-LR detector replacement.

Other components, such as the EASU, would be considered part of a shipboard installation package. There are approximately 230 shipboard installations.

7 Performance Specification. Is the AVCAD intended to survive storage temperatures only up to 52 Centigrade (3.4.1.1)?

The Performance Specification is incorrect. The requirement will be revised to 71 C as the threshold and 85 C as an objective.

8 Performance Specification. Can the government define procurement quantities for vehicle mounted AVCADs which may require auxiliary equipment for aerosol sampling at high combined wind speeds (3.4.2.4.a)? Would such equipment be included in the AVCAD SWaP calculations?

The Government is unable to define vehicle procurement quantities at this time. Platform specific equipment such as an aerosol sampler or EASU for ships is not included in the AVCAD SWaP calculation.

9 Performance Specification. Will the government define specific common chemical names that will be acceptable to meet 3.1.1.a and 3.1.1.c as part of the review of Table 3?

Yes, the Government will provide the common names as part of the PDR and CDR discusions.

10 Performance Specification. The TICs listed in Table 3 and in Section 6.4 are not consistent. Does the government have a list of TICs required to detect to demonstrate compliance to 3.1.1.e.

Table 3 is correct. The TICS listed in Section 6.4 are simply examples to aid in the definition.

11 Performance Specification. How and when will the information in Table 3 be made available to industry?

Refer to Section L.1.5.1.1.

12 Performance Specification. Are First Response concentrations (3.1.2.h & 3.1.2.i) equivalent to Rapid Response concentrations in Table 3?

Yes, Paragraphs 3.1.2.h and 3.1.2.i will be corrected to be consistent with Table 3.

13 Performance Specification. Does the government intend for the AVCAD to automatically restart in the event of a fault (3.2.1.b) or enter Degraded mode (Table 5)?

Either as appropriate for the detected fault. If the restart may clear the detected fault, such as a boot-up failure and an automatic restart would be acceptable. A hardware issue, such as a faulty pump, would be appropriate to enter Degraded mode to operate at the maximum capability possible.

14 Request clarification between ‘field level maintenance’ in Section L.4.1.2.4 and ‘organizational level’ in the Performance Specification.

There is no difference. Section L.4.1.2.4 will be updated to reflect 'organizational level'.

15 Performance Specification. Is the battery considered a consumable?

Yes, the battery is considered a consumble item.

16 Performance Specification. Please define ‘in use life’ as stated in Section 3.2.5.

Operational life of the consumble. Specifically, the consumable should last 13,500 between required replacement.

17 Performance Specification. Request clarification between MTTR under Section 3.3.4.d and as defined in Section 6.4.

Section 3.3.4.d is correct. Section 6.4 contains an error and will be revised.

Pspec page 1 of 6

1 When will Table 3 be made available? Will we receive instructions to view the document(s) prior to proposal submission?

Refer to Section L.1.5.1.1

2 Regarding requirement 3.2.5.f, what does 'in use' lifetime mean? Can the system be duty cycled in order to meet the 13,500 hours run time requirement? Is planned/regular maintenance acceptable to achieve it?

"In use" is the operational lifetime of the consumables between replacement. The system may be operated automatically on and off with a planned interval as long as the sensitivity, selectivity, and response time requirements are met in accordance with the Performance specification. Regular maintanance is acceptable such as cleaning components without replacement of the consumables

3 Regarding requirement 3.1.6.1.j, does data storage comprise all data or only the alarm data?

All data.

4 Regarding requirement 3.1.1.b, is Table 4 inclusive of all interferents required to show no inhibition to detection?

No, Table 4 is a representative list of potential background chemicals and is not intended to be all-inclusive.

5 Within the requirements in 3.1.1 and 3.1.2, requirement 3.1.2.a seems to contradict the threshold and objective requirements 3.1.1 h, i, and j. Three modes seems more appropriate for Rapid, Post- Event and {Residual}.

The Government desires to employ up to two modes.

6 What is the required confidence interval around the 90% PID? Does this confidence interval change with the {95%} PID objective?

The Probability of Detection and Probability of Identification are determined with 90% Confidence Intervals. The Confidence Interval does not change between the Threshold and Objective.

7 If there are multiple agents in table 3 that are chemical analogs, should the system report the general agent class or the specific agent variant? If the system reports the agent class, how will this impact the PID assessment? If the system reports the specific agent variant, how would the class-level ID impact the PID assessment?

The System should report the specific agent variant. Identification by common chemical name/military designation is a threshold requirement as of the latest draft CDD. That said, class ID for certain classes of compounds that are extremely difficult to distinguish may be sufficient. The assessment and analysis of system performance will take the system capability into consideration with a hierarchy of correct agent identification then correct class identification versus an incorrect class identification.

8 In reference to 3.2.4.c (“The AVCAD shall comply with the current version of the JPEO-CBD CCSI specification or per contract requirements”), can you please confirm the current version of this specification and how it can be procured?

The current CCSI Version is v.1.1.2. A package of the CCSI standard with test tools and implementation guide is available.

Offerors may submit request to the Contracting Officer.

9 In reference to 3.1.6.2.a (“The Remote Alarm shall provide audible and visual identifications of a chemical detection”), can this requirement be further refined? Is there a specific configuration to meet this KPP (e.g. separate hardware or a remote software application operating on a laptop)?

The Remote Alarm is separate hardware for the signaling of alarms, faults, and control of the AVCAD. All detection information that is displayed to the local detector user should be mirrored on the remote alarm.

10 Can you provide any additional information on the newly adopted requirement described in 3.1.1.c (“The AVCAD detector shall automatically detect and identify {quantify} liquid and solid chemical aerosols {dusty chemical aerosols} by common chemical name of military designation, and alarm to the chemicals in Table 3”)? The language in this KPP is similar in scope to that described in the draft MPCAD RFP. To what extent of “identification” meets the scope of this requirement?

The AVCAD should report the specific chemical compound detected, such as, GB for Sarin.

11 Requirement 3.1.1.f and 3.1.1.g reference constant concentration and dynamic concentration. Can the government provide clarification on the dynamic concentration term?

The concentration of the chemical provided to the unit under test may be held at a steady state (constant) concentration or varied (dynamic) concentration with time. In either case, the concentration will be maintained above the minimum required detection threshold at all times.

12 Does the government intend for the Contractor to provide a Remote Alarm that is different than the military standard M42 alarm (2.1.6.2)? If so, what are the requirements for range and wireless?

Yes, refer to the requirements in Paragraphs 3.1.6 and 3.2.4.

13 Does the government intend for the contractor to identify by individual chemical? I.e., to differentiate between GB, GD etc. and between V series chemicals, or is some sub-grouping sufficient, for example breaking down Nerve in to G, V, etc.?

Yes, per Paragraph 3.1.1 identify the chemical name (Sarin) or Military Designation (GB). Identification by class, i.e. nerve, is not desired as the primary identification.

14 Did prior testing in TMRR phase support the addition of KPPs within the April 2017 PSPEC?

No, the requirements in the Performance Specification are derived from the Joint Service Combat Developers needs.

15 Why was there a shift of requirements from class level identification as documented previously in the Jun 2016 PSPEC to current KPP requirements for identification as outlined within the April 2017

PSPEC?

The Joint Service Combat Developers would like to retain the identification capability provided by the currently fielded M4A1 Joint Chemical Agent Detector in future detectors.

16 TRL 6 definitions provided do not seem to be consistent with the stated KPPs. Please clarify which system characteristics are KPPs

The AVCAD Key Performance Parameters are identified with the acronym "KPP" at the beginning of the requirement statement.

17 What is meant by “common chemical name or military designation”? Is GA, GB, VX etc. the “common chemical name” or the “military designation”? Is there a one to one mapping between “common chemical name” and “military designation”? If not, does the contractor choose which one we identify by?

GB is the military designation. Sarin is the common chemical name. Refer to Chapter II of U.S. Army Field Manual 3-11.9 (FM 3-11.9) Potential Military Chemical/Biological Agents and Compounds, January 2005 for the mapping.

18 With regard to 3.2.5.f, the requirements ask for the ability to download stored data. Is this in addition to the CCSI protocol that (we believe) specifies data download requirements? I.e. Is this meant to be an additional function that is perhaps initiated from the sensor user interface rather than C&C? For example do they want the user to plug in a USB stick and then select ‘download data’ from the user interface?

Yes, this is the capability to locally download data onto a removeable media or laptop computer.

19 Reference Paragraph 3.1.1.l. Will the Government explain what is envisioned by the vapor sensor and alarm components being able to be "removed to be employed as a wearable sensor"?

The objective specification is intended to allow the warfighter to employ a portion of the entire system as a soldier worn vapor only detector. The subject detector would have to impose a small SWaP burden on the warfighter.

20 Reference Paragraph 3.1.2.d. Will the Government clarify which mode the MTBFA is expected in versus the mission? Are different MTBFAs expected for rapid response, post event, and residual monitoring approaches?

The MTBFAs apply to all operational modes of the AVCAD.

There are not different MTBFAs for the different sensitivity levels cited in Table 3.

Pspec page 2 of 6

21 Paragraph 3.1.2.h states a range of 10 times greater than the first response concentrations. Should this be rapid response concentrations?

Yes, Paragraphs 3.1.2.h and 3.1.2.i have been corrected to be consistent with Table 3.

22 Paragraph 3.1.2.i states concentrations greater than 10 times the first response concentrations. Should this be rapid response concentrations?

Yes, Paragraphs 3.1.2.h and 3.1.2.i have been corrected to be consistent with Table 3.

23 Reference Paragraph 3.1.3.c. Do the modular components include platform specific hardware mounting pieces? Can the platform mounting pieces require the use of tools?

No, platform specific components are not considered modular (field installed) components. Yes, tools may be used to install permanently mounted platform components.

24 Paragraph 3.1.3.d states the system should operate for 12 continuous hours without battery replacement.

What mode is the system operating in? Does it include the aerosol capability?

The vendor should design their system to operate for 12 continuous hours in the worst case (highest) power consumption, operational mode.

25 Reference Paragraph 3.1.6.1.o. We suggest the Government provide an expected download frequency (i.e., at least monthly) or a maximum operation time that would be expected for the event and fault logs to be maintained in memory.

The Government revised Paragraph 3.1.6.1.o. as follows:

Maintain a minimum of 100 Event and Fault Log occurrances until deleted by operator action.

26 Reference Paragraph 3.1.6.2.f. Does the requirement for operation for 12 hours on batteries refer to the remote alarm or the communications part of the AVCAD itself?

Paragraph 3.1.6.2.f refers to the Remote Alarm

27 Reference Paragraph 3.2.2.e. Would the HALO and HAHO operations be while in its transportation case or when held by a person?

Paragraph 3.2.2.e refers to airdrop as packaged equipment.

28 Paragraph 3.2.5 f and Paragraph 3.2.5.g require nearly 1.5 year consumable life for the shipboard variant. Is it to be assumed that these would be different consumables from those used in normal operation if needed to meet those specifications?

Correct

29 Paragraph 3.3.5.e states the system shall "operate safely in an atmosphere of explosive vapors IAW MIL STD-810". The auto ignition temperature may be lower than temperatures that the system will likely need to operate at for efficient chemical transfer.

This could cause challenges to making the system intrinsically safe, and alternate approaches may need to be considered as adding a flame suppressor would impact chemical sensitivity. Will the Government provide additional clarification as to the expectations for this requirement?

The Government expects to employ safe equipment that does not pose a hazard during Military operations such as aircraft refueling.

The subject requirement is interpreted correctly. Operation of internal system components above the autoignition temperature of n-hexane does not necessarily pose an explosive or explosion propogation hazard for properly sealed equipment.

Requirements that adversely impact overall system performance as noted here should be a topic at the PDR and CDR for an informed collaborative desicion.

30 The lower end of the temperature ranges for operation in Paragraph 3.4.1.1 and 3.4.1.2 are challenging, and compliance will be a significant cost driver in the system design. We suggest considering making the low end for operation 0 ˚C as a trade-off.

For low temperature operation, could a secondary bag/heater be considered with a separate battery supply?

Note that 3.4.1.1 is a non-operational storage temperature. The Government is not inclined to modify Paragraph 3.4.1.2 at this time. Requirements that adversely impact overall system performance or logistics should be a topic at the PDR and CDR for an informed collaborative decision.

31 We suggest moving Paragraph 3.4.2.1.b to the shipboard section (Paragraph 3.2.5) for consistency so all shipboard requirements are kept in one section.

This specification relates to both induced environment as well as shipboard and is noted accordingly. The Government anticipates leaving the current format.

32 We suggest moving Paragraph 3.4.2.5 to the shipboard section (Paragraph 3.2.5) for consistency so all shipboard requirements are kept in one section.

This specification relates to both induced environment as well as shipboard and is noted accordingly. The Government anticipates leaving the current format.

33 Section 3.1.1.a states “KPP: Automatically detect and identify {quantify} CWA {NTA} chemical vapors by common chemical name or military designation, and alarm to the chemicals in Table 3.”

a. Is identification by chemical class, e.g. NTA, G-series Nerve, V-series Nerve, and Blister sufficient for identification?

b. Automatic detection and identification of CWA by common chemical name or military designation is stated as a threshold requirement. Previous guidance provided in answers to questions on the June 14 2016 Draft PSPEC indicated that identification to class (ie, V-series) was the threshold requirement.

Has this requirement changed?

a. Identification by common chemical name/military designation is a threshold requirement as of the latest draft CDD. That said, class ID for certain classes of compounds that are extremely difficult to distinguish may be sufficient.

B. This requirement has changed, per the latest draft CDD.

34 Section 3.1.1.c states “KPP: Automatically detect and identify {quantify} liquid and solid chemical aerosols {dusty chemical aerosols} by common chemical name or military designation, and alarm to the chemicals in Table 3.”

a. Is identification by chemical class, e.g. NTA, G-series Nerve, V-series Nerve, and Blister sufficient for identification?

b. Is the requirement for identification of liquid and solid aerosols addressable by ID to a class or category of NTAs? If so, is a contractor defined class acceptable?

c. Is there still an option for alarming by chemical class rather than chemical name?

d. Is the detection of aerosol NTAs a KPP?

a. Identification by common chemical name/military designation is a threshold requirement as of the latest draft CDD. That said, class ID for certain classes of compounds that are extremely difficult to distinguish may be sufficient.

B. Class ID for certain classes of compounds that are extremely difficult to distinguish may be sufficient. A contractor defined class may be acceptable.

c. See "a." above.

d. Yes

Pspec page 3 of 6

35 Section 3.1.2.c states “Provide the capability for the operator to select (Operator Selected Mode) chemical sensitivity or specific chemical agent, chemical agents, class, or classes of agents (e.g., nerve CWA detection for GA, GB, GD, and GF) to be detected.”

a. Does the Government prefer the sensitivity selection to utilize naming convention in Table 3, e.g., "Rapid Response", "Post-Event Monitoring", and {"Residual concentratation"}?

b. Section 3.1.2.c. defines multiple options for Operator Selected Mode menus. What is the threshold requirement?

a. The Government is open to other naming conventions.

B. Revised this section. An Operator Selected Mode for sensitivity is not required if the proposed system can achieve both the Rapid Response and Post-Event Monitoring concentrations in 30 seconds and 180 seconds, respectively, in one mode. The ability to select the agent or class of agents to be detected is objective.

36 Section 3.1.2.g states “Automatically transition to no-alarm status within 120 sec {60 sec} of the system being removed from agent exposure.” The PSPEC defines three potential sampling intervals: 30 sec, 180 sec, and 10 min. Normal operating mode refers to the 30 sec sampling interval. It is assumed this requirement corresponds to sampling in the normal operating mode 30 second sampling interval.

a. Should the timeframe for switching to no-alarm status be tied to the sensitivity level setting (Rapid Response, Post-Event Monitoring, or Residual Concentration) rather than a fixed time frame of 120s? Collection at longer time intervals increases the risk of a larger accumulation of target material, which may require longer clear down times.

This section has been revised to "Automatically transition to no-alarm status within 6 min {60 sec} of the system being removed from agent exposure.

37 Section 3.1.3.e. Regarding the requirement to download data to “removable media,” is it the Government’s intent that the communications module be able to accommodate specific removable media formats? If so, which removable media formats are required?

a. Does all data, including spectra and log files, that are exported from the instrument need to be encrypted and if so, what encryption standard should be used?

The vendor should provide USB and/or ethernet ports to provide the ability to download data.

Plug and Play USB storage device compatibility, such as flash drive or portable hard drive, is desired.

Downloaded data files, including spectra and log files, require encryption as described in NIST SP 800-111 "Guide to Storage Encryption Technologies for End User Devices" provided at this link: dx.doi.org/10.6028/NIST.SP.800-111

38 Section 3.1.6.1.b states “Display common chemical name or military designation {concentration level indication}.” Is identification by chemical class, e.g.

NTA, G-series Nerve, V-series Nerve, and Blister sufficient for identification?

Identification by common chemical name/military designation is a threshold requirement as of the latest draft CDD. That said, class ID for certain classes of compounds that are extremely difficult to distinguish may be sufficient.

39 Sections 3.1.6.1.q and 3.1.6.2.j . Is it the Government’s intent to require “remote” turn-off of wireless connectivity?

"Remote" turn-off of wireless connectivity is not required.

Local enable/disable of detector and alarm wireless function is required.

40 Section 3.1.6.1.r states “Provide wired connectivity to the remote alarm.”

a. Is this connectivity via field wire connected to terminals such as those on the M42 alarm?

b. What are the minimum and maximum distances separating the detector and remote alarm?

a. No, the connectivity may be by a method of the contractors choosing.

B. There is no minumum distance. The maximum distance is 400 m.

41 Section 3.1.6.2 Remote Alarm Warning and Reporting.

a. What are the size and weight requirements of the remote alarm?

b. Is it desirable to have the remote alarm run on AC power or recharge its own battery?

A. No larger than 6 x 6 x 6 inches and weight no more than 5 lbs is desired.

B. Both shore power (AC/DC) and battery power (chargeable on-board or chargeable battery packs) are required.

42 Section 3.1.6.2 Remote Alarm Warning and Reporting. It is implied that wireless communication between the detector and the remote alarm is accomplished by use of the 802.11 standard wireless communication referenced in paragraph 3.2.4.h.

a. Please confirm this interpretation of the wireless requirement for the remote alarm?

b. This section also implies that the remote alarm be required to respond to and display alarms from the AVCAD, de-alarms from the AVCAD, malfunction status from the AVCAD, and malfunction status of the remote alarm. No other data such as concentrations or agent identification is communicated to or from the remote alarm. Please confirm that this assumption is accurate and does the remote alarm need to communicate its own malfunction status to the detector?

c. Do any encryption standards apply to the communication between the AVCAD and the remote alarm?

A. Built-in 802.11 communication between the detector and remote alarm is required, but it not meant to imply it is the solution for wireless connectivity to the Remote Alarm at distances in an urban environment up to 200 m {1,000 m} as specified in section 3.1.6.1.p.

B. The subject assumption is not correct. All detection information that is displayed to the local detector user should be mirrored on the remote alarm. Remote alarm fault information does not have to be communicated to the detector.

C. The minimum security requirements standard is FIPS 140-2, Level 2.

43 Section 3.1.6.2.g. Please supply additional information as to how compliance will be tested. One example may be – Under appropriate conditions or with sensing equipment an audible alarm of 80 db as required by c. could easily be detected at 100 m.

a. As 802.11 is a bidirectional communications standard, the requirement for wireless communication appears to be in direct conflict with the requirement for no electromagnetic emissions beyond 100 m.

Please clarify the requirement of 3.1.6.2.g? Do the requirements of g. only apply when the alarm is not sending or receiving, such as in an alarm state, or when the alarm is connected by wire and not by wireless?

Compliance to 3.1.6.2.g will be verified with acoustic, thermal, and electronic sensors at a Government proving ground such as Dugway Proving Ground or Aberdeen Proving Ground. The test would be accomplished with the detector under normal operating conditions not under an alarm or fault condition. The question is correct in that the electromagnetic emission control does not apply to when the detector is actively transmitting or receiving.

Pspec page 4 of 6

44 3.1.6.2.h. states “Operate on an open systems architecture allowing interfaces to other sensors.”

a. Is it preferred that multiple AVCAD detectors be able to connect to the same remote alarm module?

b. Is it preferred that multiple remote alarms be able to connect with the same AVCAD detector?

c. When operated with other sensors, are the same functions listed in requirement d (and only those functions) required?

d. What communication standards and message format are used by the other sensors?

e. Are the intended “other sensors” future development, or legacy devices?

A & B. Yes, connectivity from one remote alarm to multiple detectors or multiple remote alarms to a single detector is desired.

A mesh network topography is desired.

C. When operated with other detectors, additional functions may be required. Hence, an open architecture (non-proprietary software) shall be used which allows the modification of the remote alarm or interfacing detector software for the desired functionality. The remote alarm should use CCSI as the interface for communications with the detector.

D. Not applicable.

E. To be determined.

45 Table 3, Sensitivity Levels. Three levels of required concentrations for detection (rapid response, post event monitoring, and residual concentration) are indicated but shown only by reference to a classified table.

a. If these levels are classified and not defined to the contractor, how can the contractor indicate that their system design will be compliant?

b. Can you provide us with access to the classifed list pre-proposal?

Please refer to Section L.1.5.1.1.

46 Table 5, AVCAD States and Modes . With in the description of the Power Up State the PSPEC states “If all system components pass during BIT Mode, the AVCAD shall progress into the Normal Operation Mode of On State.” A typical CONOPS would require the operators to enter confidence check mode PRIOR to entering Normal Operation Mode. Rather than progressing directly to Normal Operation Mode upon completion of power up, would the Government reconsider progressing into confidence check mode or giving the user the option of which on-state mode to progress into?

The Power Up State in Table 5 is correct as written. The detector should automatically enter into the Normal Operation Mode as quickly as possible. The Confidence Check is a desired function by the operator but not a required function for the proper operation of the detector. The detector CONOPS would be that the Operator should conduct the Confidence Check by menu manipulation after the system has entered Normal Operation.

The Operator may also chose to move the detector into different modes as dictated by the mission.

47 Table 5, AVCAD States and Modes . The On State is composed of seven modes: Normal Operation, Degraded Operation, Configuration, Confidence Check, Maintenance, Training, and Defunct. BIT functions shall continuously monitor system status and the system shall notify the operator of any failures. We respectfully suggest the new operator selected mode should be added to this description

Concur. The Operator Selected Mode is included in Table 5 under On State and will be added to the header description.

48 Table 5, AVCAD States and Modes . In Operator Selected Mode, AVCAD chemical sensitivity is selected to be either Rapid Response Concentration (30-sec response time) or Post-Event Monitoring Concentration (180-sec response time). Can a contractor assume that if the AVCAD is capable of meeting the objective requirements associated with the Residual Concentration sampling interval (10 minutes), that the selection of sensitivity in Operator Selected mode would include this option?

It is assumed that the objective "residual concentrations" would be achieved when selecting Post-Event Monitoring Concentration (180-sec response time), if a separate mode is needed. An Operator Selected Mode for sensitivity is not required if the proposed system can achieve both the Rapid Response and Post- Event Monitoring concentrations in 30 seconds and 180 seconds, respectively, in one mode.

49 Table 5, AVCAD States and Modes . Operator Selected Mode states “Additional operator configurable settings, such as single chemical detection, may also be instituted in this mode.” And, in the Configuration Mode it states “In Configuration Mode, the operator may configure the AVCAD for the desired level of operational functionality, which may include modification of communication settings, human interface settings, selection of specific chemical(s) to be detected, and selection of system sensitivity levels."

a. Performance specification refers to selecting subset of target list in both Operator Selected Mode and in Configuration Mode. Restricting target list modifications to configuration mode only may reduce training burden. Would the customer consider relocating the requirements of operator selected

Yes, the Government does not desire the same information in two locations. In order to avoid confusion, Table 5 will be updated to have the chemical sensitivity and selectivity only under the Operator Selected Mode. Other non-detection settings will be retained under Configuration Mode.

50 Table 5, AVCAD States and Modes . Normal Operation mode definition includes start up in “First response” (30 sec) concentration. If there are no detections within 10 minutes, is it acceptable for the system to default to (or prompt the operator to change to) more sensitive 180 second sampling to preserve battery life?

No. Options for preserving battery life can be covered in training.

Switching to a 3-minute response time should be a conscious decision by the user.

51 Table 5, AVCAD States and Modes – Defunct Mode states “An authorized command by the operator, network, or Remote Alarm shall place the AVCAD into a Defunct Mode. This mode requires implementation of an operator key or mechanical function to avoid accidental trigger.” Can the government provide clarification on the user and authentification modes the system should be designed to support?

Not at this time. The implementation of User Authentication will be worked out jointly between the Government Combat Developers, Government Material Developers, and Contractor as part of the preliminary and critical design trade-offs.

52 Section 3.2.4.a states “KPP: Be operational on a network in less than 30 min. {10 min.} with a minimum of 98% network connectivity.” Please clarify how this is to be verified.

As an example for verification, a minimum of 3 sensors will be timed to connect to 3 hosts. The hosts can be a minimum of 3 remote alarms or 3 communication systems used in the field right now such as Joint All-Hazards Common Control Station (JACCS) as an example. We will only test the sensor side in terms of setting up, connecting and passing test alerts/alarms to the nodes

53 Section 3.2.4.c states “KSA: Comply with the current version of the JPEO-CBD CCSI specification or per contract requirements.” What CCSI version is required for this contract?

The current version for the CCSI Standard is v1.1.2.

54 Section 3.2.4.e. Regarding data in transit encryption

– Please provide details or implementation guides for the referenced standard.

Data in Transit may require employment of AES 128, AES 256 or SHA-3 or higher.Reference the National Institute of Standards and Technology (NIST) Guidance on FIPS 140-2, Level 2 at:

55 Section 3.2.5 Shipboard Interface and Appendix B – Interface Control Document for Shipboard Application. Customer intent (3.2.5) appears to be to replace all functional modules of the current installed IPDS-LR, however Appendix B states a desire to keep as much as possible of the legacy system with the exception of the detector.

a. The IPDS system description provided does not provide sufficient performance or interface requirement definition to allow the contractor to design replacements for the EASU, CD, or RD. If the intention is for the contractor to potentially re-use elements of the legacy system, additional design as well as actual performance information is requested to support the contractors re-use/redesign decision process. Please clarify the Government’s intent as well as provide the requested design and test data.

The Government intention is to reuse as many of the existing IPDS-LR components as possible to avoid cost associated with replacement of installed equipment. The EASU does not provide any powered (fan or blower) support to the detection unit. Air is drawn by the pump contained in the detector through a filter in the EASU inlet, then through up to 6 feet of 3/16" ID tubing, into the detector and back out through the EASU exhaust. The CDU and RDU provide command and control of the detector via propietary software by the IPDS-LR Manufacturer (Bruker Corporation).

Additional interface information will be provided to the EMD Contractors as needed to support AVCAD design development.

56 Section 3.3.2 Self-test and diagnostic capabilities .

Does the requirement to isolate detected failures also include failures of external modules such as a communications interface, the remote alarm, or the various components of the shipboard system?

No only detector internal components.

57 Section 3.4.1.1. The requirement for storage temperature references the Storage State, defined in Table 5 as the AVCAD system powered off with batteries removed. Is it acceptable to insert “warm” batteries upon re-start of the AVCAD system?

Yes

58 Section 3.4.2.4 Wind part a. Are the detection requirements of section 3.1.1 applicable at wind speeds of 65 km/hr?

Yes

59 Section 3.4.2.5 Shipboard Counter Measure Wash Down. Can an exterior port on the EASU be closed (manually or remotely) prior to counter measure wash-down?

Remotely only from the CDU or RDU. The EASU may be located up on the side of a ship hull where it cannot be manually accessed by Sailors without special equipment.

60 Section 4.5.2.5, Table 19 Shipboard interfaces verification matrix. Please provide the verification test standards for the acoustic requirements of paragraphs 3.2.5.d and 3.2.5.e.

Paragraphs 3.2.5.d and 3.2.5.e will be verified using MIL-STD- 1474 Department of Defense Design Criteria Standard Noise Limits and MIL-STD-740-2 Structureborne Vibratory Acceleration Measurements and Acceptance Criteria of Shipboard Equipment.

61 Appendix B – Interface Control Document for Shipboard Application - Section 2.1. If the detector draws air from the exterior of the ship, how is the confidence check performed from the ship interior?

A Confidence Check interface port is provided on the EASU tubing just prior to the detector inlet.

62 Appendix B – Interface Control Document for Shipboard Application, Table 1 – Shipboard Physical Interfaces.

a. Is there a diameter restriction on the tubing to be used between the EASU and the AVCAD?

b. As referenced in Table 1, chemical detection sensitivity cannot be impacted by up to 6 feet of the tubing connecting the detector to the EASU. Does the current installation meet this requirement? What tubing is used, and is it heated?

A. There is no diameter restriction on the tubing size between the EASU and AVCAD. However, options to reduce condensation, to include heating the tubing and/or other components, are being considered.

B. The installed IPDS-LR tubing is PTFE and it is currently unheated. Heating is an option.

63 Appendix B – Interface Control Document for Shipboard Application, Table 2 – Shipboard Electrical and Communication Interfaces. Will the data transfer called out in the Data Port description in Table 2 be done via CCSI?

CCSI is the preferred method of data transfer. However, reuse of the existing CDU and RDU may preclude use of CCSI.

64 Section 3.1.6.1.p. Will the wireless connection from the AVCAD to the remote alarm (or alarms) be through a local node, or peer to peer?

Peer-to-Peer

65 Section 3.2.2.b states “Operate on the interior of aircraft in flight and during aircraft ground servicing tasks to include, but not limited to, aircraft refueling, handling of explosive ordnance, loading and off-loading cargo, routine maintenance, preflight and post-flight inspections, and fleet servicing equipment and materials.”

a. If the aircraft interior is unpressurized, can the Government supply the maximum altitude or minimum atmospheric pressure at which the AVCAD must operate?

b. If the aircraft interior is pressurized, can the Government supply the equivalent altitude or minimum atmospheric pressure created by the aircraft’s internal pressurization?

c. Is this requirement distinct from the 3.4.1.10 High

A and B. The aircraft interior will be pressurized. The maximum aircraft interior pressurization is equivalent to 4,000 m (87.5 kPa).

C. The requirement is not distinct from Paragraph 3.4.1.10 and the ground operational requirement of 4,572 m (57.2 kPa) is higher than the pressurized aircraft requirement.

66 Section 3.2.4.c. Given the encryption requirements referenced elsewhere, security might require restricted access to the data on the AVCAD.

a. Is it required or desirable to require password access or other authentication to operate the

AVCAD?

b. Is it required or desirable to require password access or other authentication to send information from the AVCAD via CCSI?

A. The Government anticipates that the AVCAD will contain different levels of access restrictions. The General Purpose User may be an uncleared warfighter. Hence, there should be no restrictions on access. Higher levels of authentication will be required for maintenance access to the AVCAD.

B. Authentication will be required to initiate communication for the AVCAD. After the initial authentication no additional authenitication should be required for CCSI data transfer. The General Purpose User will require access to send messages

1 Paragraph C.7.2 of the PWS defines the delivery of the 60 LRIP 2 systems as commencing "five months after contract option award at a rate of ten AVCADs per month." On the other hand, there are no expected delivery dates or rates defined for any of the FRP quantities (C.8 - C.13). Given the potentially large total quantities for these options ("up to 11,635"), delivery times and rates would allow us to do better production planning and pricing

FRP production quantities may be divided equally over 12 months. The lead time from option award to first delivery is negotiable.

2 Paragraph C.7.1.1 of the PWS requires delivery of 68 LRIP 1 systems "4 months after option award." Does this mean that all 68 systems should be delivered at one time or is there a preferred delivery rate per month?

All 68 systems should be delivered at one time.

3 Regarding Section C.4.4, would the Government consider extending the first delivery of the six prototypes with the two different front ends?

Section C.4.4 has been revised to extend delivery of CLIN 0001 and CLIN 0002 to six (6) months after contract award

4 Regarding Section C.4.5, are the hours of testing listed for a single system or total time?

The hours are to test a single system.

5 Option 1. When will Option 1 be exercised? Introducing an option this early may disrupt the continuity of the sensor development.

The intent is to award this option either after customer testing, or after the CDR.

6 Regarding C.5.1.1, would the government consider extending the four-month delivery schedule since the final front-end design will only be decided at the conclusion of the base period?

The Government will not delay the initial delivery of the First AVCAD EMD Hardware at this time. The Government has revised this section to break up the delivery, with 24 due 4 months after option award, and 36 due 6 months after option award.

7 The conclusion of the base period appears to be a down-select, is this accurate? If so, what are the criteria for the down-select?

This is not a competition. The intent is to award the EMD option for both contracts if customer test results indicate promising performance, to increase potential for at least one system successfully completing EMD. See answer to question #3 on the General Tab.

8 Will the NGCD Program Documents referenced in Section C.2.6 be released with the AVCAD RFP?

Yes.

9 Will the NGCD 1 SEP be released with the AVCAD RFP?
