The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of an Analog I/O Module, identified by NSN 7R-6130-015892473-P8. This procurement involves a quantity of four units, which require engineering source approval due to their flight-critical nature and the necessity to maintain high-quality standards. Interested vendors must be approved sources or provide detailed documentation for source approval, as the government intends to negotiate with only one source under FAR 6.302-1. Proposals must be submitted within 45 days of this notice, and interested parties can contact Gina P. Sassane at (215) 697-2198 or via email at GINA.P.SASSANE.CIV@US.NAVY.MIL for further information.
