The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of intercommunication and public address systems, identified by NSN 0R-5831-016902235-QE, with a quantity of 54 units required. The procurement is critical as the design of the part is unstable, necessitating significant changes that may render the current configuration obsolete; thus, government source approval is mandatory prior to contract award due to the flight-critical nature of the item. Interested vendors must provide detailed technical data and evidence of prior experience in producing similar items, as proposals lacking the required documentation will not be considered. For further inquiries, interested parties can contact Dianne L. Wydra at (215) 697-6681 or via email at Dianne.L.Wydra.CIV@US.NAVY.MIL, with a proposal submission deadline of 45 days from the notice publication date.
