The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 16 units of the THRUSTER, CARTRIDGE (NSN 1R-1377-011569797-GF, REF NR 2715200-4). This procurement is critical as the item is flight critical, and the Government requires source approval prior to contract award, limiting the solicitation to previously approved sources only. Interested parties must submit detailed technical data and source approval documentation with their proposals, as offers lacking this information will not be considered. For further inquiries, Danielle Diciacco can be contacted at (215) 697-5970 or via email at DANIELLE.DICIACCO.CIV@US.NAVY.MIL, with a proposal submission deadline of 45 days from the notice publication date.
