ATTACHMENT 0012

Questions and Answers

The following questions have been submitted in response to solicitation W52P1J‐18‐R‐0143.

Q1. I noticed that Attachment 0002 is actually Attachment 0012 and ...0002 is missing from the list...

A1. The Attachment entitled “B08 – ATTACHMENT 0002 – Scheduled Government Furnished Property (1)” has been corrected from Attachment number 0012 to Attachment number 0002.

Q2. Can the USG provide clarification with regard to monthly delivery requirements? Below, is a paragraph from page 3 of the solicitation.

#12. Deliveries shall commence 365 days after issuance of the Delivery Order. All quantities awarded shall be delivered within 12 months of the start of production. The subsequent delivery orders will be issued with or without FAT. If the Delivery Order is issued with FAT, the delivery schedule requirements will be as stated above following the same FAT requirements. If the Delivery Order is issued without FAT, monthly deliveries will continue at the same rate and immediately after the delivery schedule in place for the earlier items. The delivery schedule is set forth in Section B of the Delivery Orders. Early deliveries, defined as deliveries occurring prior to the scheduled month, require prior written contracting officer authorization.

So if we’re interpreting this correctly, regardless of whether the USG orders 10,000 or 100,000, the balance of the DO would be due in 12 months. In this example, the contract could require monthly delivery of 834 per month or 8,334 per month.

If the above assumption is true, then delivery quantities could vary by a factor of 10x. This poses a dilemma for prospective offerors, as under or over estimating floor space and equipment could pose significant risk to both the USG and the contractor.

Can the USG provide more insight on historical demand / and or possible minimum monthly requirements?

A2. Yes, your assumption is correct. Once production is started, deliveries are required to be completed within 12 months. On Attachment 0001, Price Matrix, the weights next to each quantity range provides a breakdown of the likelihood we plan to place additional orders within that quantity range. For example, for MK76 Ordering Period 1 the most probable range is 30k‐69,999. For Ordering Period 2 for MK76 the most probable quantity is 70K ‐ 109,999.

Q3. The solicitation references BDU‐33 D/B, SP7729467 and 7729467‐10. We've been unable to find these drawings and documents in the TDP provided by the USG under this requirement. Also, it is not referenced in the ADL. Can the USG provide some guidance?

A3. The drawing/spec are part of Data List (DL) 7729467 Rev K. This should be in the DL that was sent for this solicitation. They should be listed on the DL, not an Automated Data List (ADL). For dwg 7729467‐ 10, the "‐10" is the configuration on dwg 7729467.

Q4. Bomb Practice, Empty MK76 Mod 5 (PN 2193779, REV AT) Note 4 requires paint, but there is no coating thickness requirement. Is there a next level of assembly drawing(s) that were left out of the TDPL for this requirement?

A4. Paint thickness should correspond to MIL‐STD‐11195 (formerly MIL‐DTL‐11195) which is 0.0013 to

0.0017 inches thick. This is the same thickness required for the testing in section 4.3.24 SALT SPRAY

RESISTANCE.

Q5. The Lug (PN 1555268) when assembled in the Bomb, Practice, Empty MK76 Mod 5 (PN 2193779) does not have an installation torque or rotational clocking requirement. Can the USG provide more detail on the installation requirements for the Lug?

A5. For installation of the lug, there is no required torque. Dwg 2193779 page 2 demonstrates how the lug shall be installed.

Q6. One of the revisions made to the MK14 suspension lug print, 1555268 Rev‐AE, states in note 2;

100% Mag Particle screening of raw forgings prior to heat treatment.

Rev‐AD states, 100% Mag Particle screening of raw forgings

NDT prior to heat treatment of forged lugs is not the norm and I wanted to confirm the accuracy of the change, it contradicts the requirements in ASTME 1444.

A6. Having the lugs go through MPI before heat treatment helps keep the forging process dialed in. This is the step that the most discontinuities may form from. Having the lugs inspected prior to heat treatment allows the forging facility to determine if their dies are working properly and fix them once an issue arises instead of after shipping thousands of lugs to the machining/heat treatment location to have them thrown away resulting in cost/schedule impacts.

This requirement is consistent with Section 5.4 of the ASTM E 1444. "Examination Sequence‐Perform examination after all operations which might cause or reveal discontinuities. Such operations include, but are not limited to, forging, heat treating, electroplating, forming, welding, grinding, straightening, machining, and proof loading."
