PERFORMANCE WORK STATEMENT

Unmanned Maritime Systems Support Component Environmental Testing of the MK 18 Mod 2 Unmanned Underwater Vehicle (UUV) System Revised 7 September 2018

INTRODUCTION

Space and Naval Warfare Systems Center Pacific (SSC PAC), San Diego is procuring program services in support of Explosive Ordnance Disposal Unit Expeditionary Mine Countermeasures (EOD ExMCM) companies.

Background The MK 18 Mine Countermeasures Unmanned Underwater Vehicle (MCM UUV) project is in the process of fielding in support of the EOD ExMCM companies. There are two basic vehicles: the MK 18 Mod 1, based on the Hydroid REMUS 100 UUV, and the MK 18 Mod 2, based on the Hydroid REMUS 600 UUV. U.S. naval forces have deployed and operated MK 18 Mod 1 systems for approximately 8 years. Initial MK 18 Mod 2 systems have been operating in the Middle East out of Bahrain since 2012, operated by civilian contractor personnel. These MK 18 Mod 2 systems have been turned over to, and are now being operated by, EOD ExMCM Companies. Additional MK 18 UUV systems have been purchased and delivered in support of an expanding MCM mission in the EOD community. MK 18 operations are accompanied by a host of support equipment such as shelters, launch and recovery systems, maintenance vans, etc.

The baseline Mod 2 UUV is equipped with an EdgeTech Side Look Sonar (SLS) package that addresses MCM Search-Classify-Map (S-C-M). It also comes equipped with a downward-looking video camera, providing imagery beneath the UUV that is used for visual identification of mines during Reacquire and Identify (R-I) mission types.

The MK 18 Mod 2 UUV Block B upgrade includes replacing the MK 18 Mod 2 UUV’s EdgeTech Sonar and Video Camera Payloads with the Small Synthetic Aperture Minehunter Version 2 (SSAM2) Payload, which will provide enhanced performance by increasing resolution and range while adding the possibility of a buried target detection capability.

Another upgrade to the baseline system is the Autonomous Topographic Large Area Survey (ATLAS) Forward Looking Sonar (FLS) and is entitled MK 18 Mod 2A IPOE. The ATLAS FLS is intended to provide a large area coverage capability for IPOE missions as well as in-volume mine detection. The ATLAS FLS is packaged as a field-configurable plug-and-play module for the baseline vehicle Scope The contractor shall provide support for the EOD UUV program under the cognizance of SSC PAC. The contractor shall provide the technical and logistical support necessary to determine if the Equipment Under Test (EUT) listed in Section 3.2 meet the environmental standards and electromagnetic environmental effects (E3) standards listed in Error! Reference source not found.. Specific tasks are outlined in Sections 3.5 through 3.7.

System Description Three unique configurations of the MK 18 Mod 2 UUV are under test; the baseline, Small Synthetic Aperture Minehunter Version 2 (SSAM2), and Autonomous Topographic Large Area Survey (ATLAS). The baseline MK 18 Mod 2 Increment I UUV (Figure 1) is equipped with side scan sonar, a video camera, and a host of other sensors to aid in its primary MCM mission.

Figure 1 Baseline MK 18 Mod 2 UUV A sensor upgrade to the baseline MK 18 Mod 2 includes replacing the MK 18 Mod 2 UUV’s EdgeTech side scan sonar with the SSAM2 payload. This sensor provides enhanced performance compared to the baseline EdgeTech by increasing sonar resolution and range while adding an additional low frequency sonar. The SSAM2 configured MK 18 Mod 2 UUV is pictured in Figure 2; note this figure is not to scale relative to other UUV images.

Figure 2 SSAM2 Configured MK 18 Mod 2 UUV A second sensor upgrade to the baseline MK 18 Mod 2 system is the ATLAS Forward Looking Sonar (FLS). This sensor provides a large area coverage capability for Intelligence Preparation of the Operational Environment (IPOE) missions as well as in-volume mine hunting capability. The ATLAS FLS is packaged as a field-configurable plug-and-play module for the baseline vehicle that is installed in front of the EdgeTech sidescan payload section (Figure 3).

Figure 3 ATLAS Configured MK 18 Mod 2 UUV

Detailed System Description The MK 18 Mod 2 UUV system is comprised of seven groups of equipment: the UUV group, the UUV auxiliary group, the UUV information technology (IT) group, the mission support group, the power distribution group, the UUV outfitting spares, and the boat group.

The UUV group contains the hull sections that comprise the UUV itself. Each MK 18 Mod 2 system consists of three individual vehicles, and each vehicle can be broken down into four sections for transportation. The front nose section of the vehicle, the dry payload section, the acoustic doppler current profiler/main housing, and the tail components are assembled using a v-band clamp system.

The MK 18 Mod 2 UUV is equipped with a host of sensors, which provide data that is critical to complete a variety of missions. Primary system sensors include an EdgeTech side scan sonar, downward looking video camera, ADCP, beam attenuation meter (BAM) to measure turbidity, and a conductivity temperature depth (CTD) sensor. The vehicle also contains subsystems to support navigation, communications, and propulsion.

The UUV auxiliary group includes auxiliary equipment required to operate the vehicle. This includes the surface communication stations, underwater transponders, ruggedized laptops, underwater communication systems, antennas, and gateway buoys. Equipment is packed into six containers for transportation.

The UUV information technology (IT) group includes all the IT equipment required to operate the vehicle. This includes the Common Operator Interface (COIN) laptop, monitors and associated computer peripherals. Also included in this group is a data archival unit (DAU) utilized for mission data set storage. The MK 18 Mod 2 sensors can produce a large quantity of data, and the DAU provides the storage space necessary to retain this data during an operation. Upon concluding an operation, the data stored on the DAU is transferred to a storage system located at the base of operations, and the DAU is cleared for the next operation.

The mission support group includes a few large pieces of support equipment required to operate and maintain the vehicle. The expandable small airmobile shelter (ESAMS) is used for mission planning and data analysis, and can be used for ship-based or shore-based mission monitoring. Figure 4 shows the ESAMS in a shipping configuration and Figure 5 shows it in an operational configuration.

Figure 4 MK 18 ESAMS Portable Shelter Transportation Configuration

Figure 5 MK 18 ESAMS Portable Shelter Operational Configuration The power distribution group includes a 56.6 kW generator, a 20 kW generator, a shore-side power distribution unit (PDU), a transformer PDU for afloat operations, and all the associated power generation and transmission cable equipment required to operate the equipment in an expeditionary manner.

The MK 18 Mod 2 system boat group primarily includes the RHIB used to launch and recover the UUVs. The RHIB is an 11-meter Zodiac that completes launch and recovery (L&R) with a side launch and recovery system (SLRS); also part of the boat group. Figure 6 shows a trailered RHIB with the SLRS carrying a MK 18 on the starboard side. The SLRS consists of an A-frame with trolleys and rigging for lifting, launching, and recovering the vehicles over the side of the 11-meter RHIB. The specialized SLRS also includes shock-isolating cradles to secure and protect the vehicles during transit. A RHIB equipped with the SLRS is capable of simultaneously operating two MK 18 Mod 2 UUVs.Figure 6 MK 18 Mod 2 RHIB

SSAM2

The SSAM2 payload consists of two Synthetic Aperture Sonar (SAS) systems: a high- frequency (HF) SAS and a low-frequency (LF) SAS. The LFSAS (also referred to as BBLF for Broadband Low Frequency) extends existing PMS 408 Explosive Ordnance Disposal (EOD) capabilities by providing detection and classification for heavily scoured and some buried targets, while the combination of HF/LF SAS extends their capability to achieve the original objective parameters for false alarm rejection in their requirements documents. The SAS is designed to provide detection and classification capabilities of proud and buried targets in the highly cluttered, dynamic, and harsh environment of the SW and VSW zones.

The SSAM2 systems are also comprised of auxiliary equipment to support their missions and maintenance, and computer software for pre-mission programming. Post-processing of MK 18 Mod 2 UUV system data is accomplished using a Data Control Processor (DCP) server with Network Embedded Real-time Distributed Synthetic Aperture Sonar (NERDS) beamforming and image processing software developed by the Naval Surface Warfare Center Panama City Division (NSWC PCD).Figure 7 SSAM2 Sensor System Configuration

Component Level Tests The first segment of environmental testing will be thermal testing of individual system components in operational and transportation configurations to determine the effects of extreme temperatures on system safety, integrity, and performance as detailed below. The tests will be conducted in accordance with the MIL standard cited.

Thermal:

Test 1-2: Transportation and Storage Temperature Objective This test is to determine if the MK 18 Mod 2 and its auxiliary components can operate properly after being transported/stored in its storage configuration (in the un-powered state) in harsh temperatures. The Performance Specification defines the storage temperature as a range from -4°F (-20°C) to 145°F (63°C).

Procedure The hot temperature storage of the system will be tested in accordance to MIL-STD-810G, Method 501.5, Procedure I, while the low temperature storage will be tested in accordance to MIL-STD-810G, Method 502.5, Procedure I. The test articles listed in Table 3 and Table 4 will be placed inside their respective transit cases and then placed inside the temperature chamber. The temperature will then be raised or lowered to the test temperature at no more than 5°F/min. The hot temperature exposure for this test will be a 24-hour cycle over the temperature range of 86°F to 145°F. The temperature will be cycled for a total of seven cycles. The cold temperature exposure for this test will be three 24-hour cycles at a constant low temperature of -20°F.

After the equipment listed in Table 3 and Table 4 have experienced all cycles of the respective test, the components will be returned to room temperature at no more than 5°F/min. Once room temperature is reached, the equipment will be removed and let sit for 2 hours to ensure steady state temperature has been reached and any latent heat is dissipated. A physical audit will be conducted to determine if any damage or material distortion has been caused by the temperature tests.

All test articles will then be unpacked, requiring a workbench of at least 15 feet, and a complete system checkout (pre-mission checkout) of the auxiliary equipment will be conducted.
