The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of three units of the flight-critical item identified by NSN 7R-1560-016203775-ZR, with reference number 449-030-164-106. Due to the nature of the item, which requires Government source approval prior to contract award, only previously approved sources have been solicited, and interested parties must submit detailed technical data and source approval information with their proposals. This procurement is crucial for maintaining operational readiness, and the Government intends to solicit and negotiate with only one source under FAR 6.302-1, with proposals due within 45 days of the notice publication. For further inquiries, interested parties can contact Jake Kucowski at (215) 679-2012 or via email at jake.kucowski.civ@us.navy.mil.
