The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of a power supply, identified by NSN 7R-6130-014214773-GF, with a quantity of 22 units required. The procurement is critical as the item is flight critical, and the government requires source approval prior to contract award, limiting competition to previously approved sources only. Interested parties must submit detailed technical data and source approval requests alongside their proposals, as offers lacking this information will not be considered. For inquiries, contact Hayden Young at (215) 697-2928 or via email at HAYDEN.J.YOUNG3.CIV@US.NAVY.MIL, with proposals due within 45 days of the notice publication.
