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 information with their proposals, as failure to do so will result in disqualification.
