Vertical Stab Adapter SCD25070 LHD8

The Naval Sea Systems Command is seeking to procure 218 Vertical Stab Adapters (Bus Bar), specifically Part Number 25-25563-C, to support the SCD25070 Actron Breaker Replacement project aboard the LHD8 naval vessel. The procurement involves replacing obsolete bus bars in the switchboard to accommodate new circuit breakers as part of a modernization effort for the vessel's 450V electrical system. The requirement includes replacing 36 obsolete Actron ACB-1606 and ACB-2010 air circuit breakers across 6 of 8 switchboards, along with associated modifications to bus bars, control power wiring, and relay interfaces. This firm-fixed-price procurement operates under NAICS code 335931 (Current-Carrying Wiring Device Manufacturing) with a size standard of 600 employees. The solicitation deadline is July 29, 2025 at 12:00 PM, with delivery required by April 30, 2026.

The procurement is designated as a Total Small Business set-aside, though the government files indicate it was initially structured for Women-Owned Small Business (WOSB) concerns. The brand name justification documents reveal that DRS is identified as the sole source manufacturer capable of meeting the precise technical specifications, including specific copper composition and silver plating requirements per ASTM B700 standards. An alternative vendor, Rittal, was evaluated but found unable to meet all critical technical specifications without requiring additional engineering support and testing that would increase government costs. The materials will be delivered to the Naval Surface Warfare Center Philadelphia Division, with the place of performance listed as Philadelphia, PA. The procurement supports a critical naval vessel modernization project with delivery scheduled for April 30, 2026.
