The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of four multi-aircraft meters (NSN 7R-5210-017105697-SX, REF NR 101994-P37-IE317.1). The procurement is critical as the item is flight critical, requiring government source approval prior to contract award, and only previously approved sources will be solicited. Interested parties must provide detailed technical data and documentation as outlined in the NAVSUP Source Approval Information Brochures, and failure to submit the required information will result in disqualification from the award process. For inquiries, interested vendors can contact Bridget M. Murphy at (215) 697-5047 or via email at BRIDGET.M.MURPHY6.CIV@US.NAVY.MIL.
