This is a follow up Sources Sought Notice to an Industry Day Virtual Event held on 27 October 2026. During that event the following questions were asked. Below each question is the answer to said question.

· Question #1: Is this 10/27 conference a virtual event via a web link or on site at Naval Surface Warfare Center Philadelphia Division (NSWCPD)?

· Answer #1: This event will take place on Microsoft TEAMs. You need to register on Eventbrite to access the link.

· Question #2: For this PRE-SOL for Columbia Class BST-1 Electrical Hull Penetrators and Transmitter Cable Assemblies, do cable assembly manufacturers need to have SUBSAFE Level 1 or 2 certification for doing hull penetrator work?

· Answer #2: The Electric Hull Penetrators (EHP) is Level I material within the SUBSAFE boundary and any vendor does not need to be in NAVSEA Note5000.

· Question #3: I looked again at the link and there are no answers or questions posted let alone a specific statement about SubSafe Level 1 or 2. It does mention “ in accordance with applicable documents in Section 2.0 and the Statement of Work” but there is no such documents on the link.

· Answer #3: Again to Confirm, The Electric Hull Penetrators (EHP) is Level I material within the SUBSAFE boundary and any vendor does not need to be in NAVSEA Note5000. As for the Section 2.0 Documents and Statement of Work, those have not been provided to any vendors at this time. They will be provided at the time the official Request for Proposal (RFP) goes out. The anticipated date that the RFP goes out has not been determined yet.

· Question #4: We would request that the solicitation be issued as full and open given the NAICS code stated.

· Answer #4: Our team is still evaluating whether competing the contract as full and open or set aside is the best path forward.

· Question #5: Previously a vendor has been shown specifications for a cable used on BST-1 (BST-1 CABLE REQUIREMENTS PER 1197262 (PC 19). Is the cable still a 2SWF-2 (Modified) and if so, is a neoprene outer jacket still mandatory?

· Answer #5: The cable is still required to be LS2SWU-12 which includes a polyolefin outer jacket. Additionally, this cable will require exterior armor for EMI protection.

· Question #6: Question for you regarding Welding NDT. Do you need us to complete the Shipbuilder's LVL3 NDT?

· Answer #6: Personnel qualified to LVL 2 are permitted to perform the weld NDT, the NDT inspection must be approved by LVL 3 qualified personnel.

· Question #7: For the section where the pressure proof caps go on, are those welded to the main body and require a QQ-N-286 weld procedure? Does NSWC-PD need to certify this weld procedure?

· Answer #7: Yes, the 4 receptacles are welded to the main body. The weld type is monel QQ-N-281 to k-monel QQ-N-286. For additional guidance on performing the weld, please refer to the latest revision of NAVSEA Tech Publication 278. The procedure developed using the guidance in 278 requires NSWCPD approval. NSWCPD would be looking for the vendor to submit their weld procedure specification (WPS), product quality report (PQR), and welder qualifications for approval.
