The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 99 units of a flight-critical transfer unit, requiring repair or modification. This opportunity necessitates government source approval prior to contract award, as the technical data available has not been deemed adequate for full and open competition, meaning only previously approved sources will be considered. Interested parties must provide comprehensive documentation as outlined in the NAVSUP Source Approval Information Brochures, and failure to do so will result in disqualification from the award process. For further inquiries, potential bidders can contact Jacob A. Tarini at (215) 697-3563 or via email at JACOB.TARLINI@NAVY.MIL.
