How to bid on hydraulic drive unit repair/modification for the DEPT of the Navy
What the agency is buying and why it matters
The Department of the Navy is seeking 62 hydraulic drive units for repair or modification. These units are identified by National Stock Number (NSN) 1650-01-452-5179. This is a critical component, specifically noted as flight-critical.
This opportunity is significant because it involves specialized equipment for the Navy. While the agency intends to negotiate with a single source, they are open to considering new sources that can demonstrate their capability and meet strict qualification requirements.
Key dates and what happens at the deadline
This Request for Information (RFI) was published on August 29, 2026. The deadline for submitting capability information or proposals is October 13, 2026, at 12:00 AM ET.
If your company has an existing Basic Ordering Agreement (BOA), the submission deadline is 30 days from the publication date. Otherwise, you have 45 days from the publication date to submit your information. The government will consider all proposals received by the deadline, but a decision to proceed with a competitive procurement is at their discretion.
Who this opportunity suits
This opportunity is best suited for companies with expertise in the repair or modification of hydraulic drive units, particularly those with experience with flight-critical components. The item requires engineering source approval, meaning that previously approved sources are generally preferred.
New sources are welcome to submit their qualifications, but they must be prepared to provide detailed engineering and technical information for approval by the design control activity and the cognizant Government engineering activity. This is a specialized equipment category, requiring specific technical capabilities and adherence to stringent quality standards.
How to respond to this RFI
To access the opportunity, click “View original source” on the portal. If you land on the homepage, click it again to go directly to the bid. You may need a free account to view all documents, though this is not always required.
If you are not an approved source, you must submit specific information detailed in one of the NAVSUP Weapon Systems Support (NAVSUP WSS) Source Approval Information Brochures. These brochures outline the technical data required based on your company's experience. If your source approval request is already under evaluation, include a copy of your cover letter with your offer. Offers that do not provide all required data will not be considered.
Practical tips for a competitive response
Given that this item is flight-critical and typically limited to approved sources, thoroughly review the NAVSUP WSS Source Approval Information Brochures. Ensure every piece of requested engineering and technical information is included in your submission. Incomplete submissions will not be considered.
Clearly articulate your company's unique design capability, engineering skills, and manufacturing or repair knowledge relevant to hydraulic drive units. Highlight any experience with similar flight-critical components or work for the Department of Defense. Even though this is a notice of intent to negotiate with one source, a strong, well-documented capability statement can influence the government's decision to consider a competitive procurement.
