The Navy intends to award a sole-source contract to Sikorsky Aircraft Corporation for one shaft, with delivery FOB origin. The government does not own the data or rights needed for additional sources to manufacture this part. Any firm not already approved must submit a Source Approval Request, but the procurement will not be delayed for that approval. The solicitation will follow FAR Part 15 and Part 12 commercial item procedures, with award anticipated in November 2026. Interested responsible sources may submit a capability statement to the Navy contact for consideration.
