This Sources Sought is for market research to identify potential sources for the new manufacture of a Cylinder Assembly (NSN 1650-01-372-4178, P/N DAB3122A004-011) for the B-02 platform. The estimated spares requirement is 3 units, and performance will be at Tinker AFB, Oklahoma. No solicitation is currently available, and no budget amounts are specified. The government is interested in all business types, including small businesses, and may consider breaking the requirement out by airframe. Potential sources must be capable of full manufacturing, inspection, testing, and supply chain management, and may need to cover nonrecurring engineering costs to become an approved source.
