Description

Primary Latest Change

It is the of the Government intention to solicit a contract to manufacture and deliver a max quantity of thirty (30) Electrical Hull Penetrators (EHP). This would be approximately fifth-teen (15) EHPs per year over a 2-year (24 months) duration. An EHP assembly is defined as an EHP and the associated transmitter cable. The material being procured under this contract is LEVEL I material and is being installed in a SUBSAFE boundary. Therefore, all interested parties shall explicitly state that they are Level 1/SUBSAFE certified and have a Quality Management System (QMS) Manual and Inspection System Procedures, in accordance with ISO 9001.The contractor shall also confirm that they are capable of meeting the welding requirements below: Welding procedures, welding procedure qualification test data, and welder Qualification data will be in accordance with NAVSEA S9074-AQ-GIB-010/248. Weld procedure and qualification test data must be submitted to the Certifying Activity for approval prior to welding. Fabrication welding of machinery, piping and pressure vessels will be in accordance with NAVSEA S9074-AR-GIB-010/278Fabrication and welding of HY-80/100/130 Submarine Hull structure will be in accordance with NAVSEA T9074-AD-GIB-010/1688.The Naval Surface Warfare Center, Philadelphia Division (NSWCPD) anticipates a Firm-Fixed Price (FFP) Indefinite Delivery/Indefinite Quantity (IDIQ) requirement to procure a max quantity of thirty (30) Electrical Hull Penetrators (EHP). The NAICS: Primary North American Industry Classification System (NAICS) code for this procurement is 332999. A Firm-Fixed Price (FFP) Indefinite Delivery/Indefinite Quantity (IDIQ) contract. Based on the results of the sources sought notice published on 04 November 2025 on SAM.gov, in concurrence with the NSWCPD Director Small Business this procurement is not a small business set-aside.

Summary (Newest Update)

Background The Naval Surface Warfare Center, Philadelphia Division (NSWCPD) is a Department of Defense entity responsible for research and development, test and evaluation, engineering, and fleet support for the Navy's ships, submarines, military watercraft, and unmanned vehicles. This contract aims to procure Electrical Hull Penetrators (EHP) for the Columbia Class New Construction efforts. The EHPs are critical components that facilitate the connection of associated transmitter cables through the pressure hull of submarines. The procurement is classified as Level I material and is installed within a SUBSAFE boundary, necessitating that all interested contractors be Level 1/SUBSAFE certified. Work Details The contractor will manufacture and deliver a maximum quantity of thirty (30) Electrical Hull Penetrators (EHP), approximately fifteen (15) per year over a two-year period. Each EHP assembly includes an EHP and the associated transmitter cable. The contractor must adhere to strict welding requirements in accordance with NAVSEA standards, including S9074-AQ-GIB-010/248 for welding procedures and qualifications, as well as T9074-AD-GIB-010/1688 for fabrication of submarine hull structures. The contractor is responsible for machining, fabrication, assembly, preservation, inspection, testing, certification, and shipping of the EHPs in accordance with applicable documents outlined in the Statement of Work (SOW). Specific materials required include QQ-N-281 Class A for receptacle bodies and QQ-N-286 for various components such as inboard washers and nuts. Period of Performance 24 months Place of Performance Naval Surface Warfare Center Philadelphia Division (NSWCPD) Incumbent Analysis (see Incumbents section for more detail) This opportunity appears to have a confirmed incumbent based on contract N6449826P2008 awarded to Teledyne Instruments (value $340,389; 11/20/25–05/05/27) for “Electrical Hull Penetration FTG and Transmitter Cable Assembly.” The current requirement similarly calls for manufacturing and delivering Electrical Hull Penetrators (EHP) as an assembly that includes the EHP and associated transmitter cable, with comparable emphasis on SUBSAFE Level I installation requirements and NAVSEA welding/fabrication standards. The prior work therefore appears to be a direct continuation of the same type of hull penetration fitting/cable assembly effort for submarine applications.
