The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure a flight-critical part identified by NSN 7R-1680-016102275-E7, with a quantity of one unit required for delivery FOB origin. The procurement is restricted to sources that have been previously approved by the Government due to the lack of available technical data or manufacturing knowledge for alternative suppliers, necessitating Government source approval prior to contract award. This item is crucial for operational readiness, and interested parties must submit their proposals along with the required source approval documentation within 45 days of this notice, with inquiries directed to Sara M. Hojnowski at sara.hojnowski@navy.mil or by phone at (215) 697-2198.
