The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 46 units of a flight-critical part identified by NSN 1R-1680-016447205-EY. This item must be sourced from approved suppliers as it requires Government source approval prior to contract award, due to the lack of available technical data for alternative sources. The procurement is essential for maintaining operational readiness, and interested parties must submit their proposals along with the necessary source approval documentation to Kimberly Flores at NAVSUP WSS by the specified deadlines. For further details, contact Kimberly Flores at (215) 697-6549 or via email at Kimberly.Flores@navy.mil.
