The Department of Defense, through NAVSUP Weapon Systems Support, is seeking to procure repair services for power supply units from Northrop Grumman Systems Corp on a sole source basis. The procurement involves the repair of six units of NSN: 7R1528014169140, P/N: 1874AS1294, which are critical components for military operations, and the government does not possess the necessary data to source these repairs from alternative suppliers. Interested parties are encouraged to submit their capabilities and qualifications by email to Shamus F. Roache, with the solicitation expected to be issued on March 14, 2024, and responses due by April 18, 2024. This opportunity is not a total small business set-aside, and all proposals received within 30 days of the notice will be considered.
