This is a Sources Sought Synopsis issued under FAR Part 10 for market research purposes and does not constitute a binding solicitation or obligation to award a contract. Prospective manufacturers must demonstrate capability to furnish all labor, materials, facilities, and equipment required for new manufacture of the cylinder assembly, and may be responsible for supply chain management, logistics planning, long-lead parts procurement, quality inspections, testing, preservation/packaging, and shipping. The government welcomes responses from large businesses, small businesses, small disadvantaged businesses, 8(a) entities, service-disabled veteran-owned small businesses, HUBZone businesses, and women-owned small businesses across NAICS Code 336413 (with a size standard of 1,250 employees).

The estimated spares requirement is 41 units, though no specific contract award value or budget range is provided in this market research phase. Prospective sources should note that no funds are currently available to support responses and that the government does not intend to award contracts based solely on this Sources Sought Synopsis.
