The Department of Defense, through the Defense Logistics Agency (DLA) Aviation at Philadelphia, is seeking proposals for the procurement of 11 units of the Turret, Sensor-Sight (NSN 7R-1270-016857990-CB, REF NR D3647120-1). This procurement requires engineering source approval due to the flight-critical nature of the item, necessitating that only approved sources may submit proposals, as the technical data required for new sources is not readily available to the Government. The selected supplier will be responsible for ensuring the quality and compliance of the part, with a focus on maintaining existing unique design capabilities and manufacturing knowledge. Interested parties must contact Janelle Pepper at DLA via email at JANELLE.PEPPER@DLA.MIL or by phone at (215) 737-4132, and must submit their proposals within 45 days of this notice to be considered for award.
