The agency intends to award this requirement to Sikorsky Aircraft Corp. under an existing agreement. However, if your firm can provide this item and is not currently an approved source, you have the opportunity to submit a proposal and seek government source approval.

Key dates and deadlines

This opportunity was published on August 07, 2026. All responses must be submitted by September 21, 2026, at 12:00 AM ET. It is important to submit all required information, especially for source approval, by this deadline.

Who this opportunity suits

This opportunity is primarily for manufacturers or suppliers of aircraft gearbox assemblies, specifically those who can provide the exact NSN and part number requested. It is particularly relevant for firms that are already government-approved sources for such components. New sources are encouraged to respond, but they must be prepared to go through a source approval process.

The item is categorized under equipment, indicating a need for specialized manufacturing and quality control capabilities.

To access the full details of this opportunity, you will need to click “View original source” on the portal. If the first click takes you to the portal’s homepage, click it again to go directly to the bid. You may need to create a free account on the portal to view all documents, though this is not always necessary.

If you are not an approved source, you must submit all information detailed in the NAVSUP WSS Source Approval Brochure along with your proposal. Offers that do not include all required source approval data will not be considered.

Tips for a competitive response

Carefully review the NAVSUP WSS Source Approval Brochure. Ensure every piece of required information is included in your submission. Incomplete submissions will not be considered, especially for new sources.

Even though this is a planned sole-source award, a well-prepared and complete proposal from a new source can demonstrate your firm's capabilities and potentially open doors for future opportunities. Clearly articulate your firm's ability to meet the technical specifications and delivery requirements.

Pay close attention to the Free Trade Agreements and World Trade Organization Government Procurement Agreement clauses mentioned (FAR 52.225-3 and FAR 52.225-5), as these may impact your proposal, especially if you are a foreign supplier or using foreign components.
