The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure three units of the electro-mechanical actuator (NSN 7R-1680-015759934-EK, REF NR 825800-4). 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 for the part is not sufficiently available for open competition. The selected supplier must demonstrate unique design capability and provide necessary documentation for source approval, with proposals due within 45 days of the notice publication. Interested parties should contact Gina P. Sassane at (215) 697-2198 or via email at GINA.P.SASSANE.CIV@US.NAVY.MIL for further details.
