The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of standby temperature components, identified by NSN 7R-1680-015854941-P8, with a quantity of 2 each. This procurement requires government source approval prior to contract award due to the flight-critical nature of the item, and only previously approved sources will be considered for solicitation. Interested parties must submit detailed technical data and source approval information with their proposals, as failure to do so will result in disqualification. For further inquiries, Jacob A. Tarini can be contacted at (215) 697-3563 or via email at JACOB.A.TARLINI.CIV@US.NAVY.MIL, with proposals due within 45 days of the notice publication.
