This pre-solicitation synopsis is not an official RFP; DLAWS (Warren) intends to award a new five-year firm-fixed-price IDIQ contract for the 400 Hz Power Supply Line Replaceable Module (NSN 6130-01-674-7138), a critical circuit-card power supply for the M1A2 SEPv3 Abrams tank. The approved source is North Atlantic Industries (CAGE 0VGU1), 116 Wilbur Pl, Bohemia, New York. The Government lacks drawings suitable for competitive procurement and does not have full data rights, although the TDP is fully defined. Contractors seeking to become sources must meet the Source Approval Program requirements, including vehicle-level qualification testing at their own expense. TACOM LCMC’s Competition Management Office leads the Source Approval Program, with details available via TACOM’s Ombudsman page.
