The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking proposals for the procurement of 20 units of a flight-critical screw cap (NSN 1R-5305-016620854-RQ). This item requires government source approval prior to contract award, as it is deemed flight critical and the technical data available does not support full and open competition. Only sources previously approved by the government will be considered, and interested parties must submit the necessary documentation for source approval along with their proposals. For further inquiries, potential bidders can contact Nadia Govorushko at (215) 697-2813 or via email at NADIA.GOVORUSHKO@NAVY.MIL.
