How to bid on Control BOX Ass, in Repair/modification of for the Dept of the Navy
What the Navy is buying and why it matters
The Department of the Navy is seeking repair or modification services for Control Box Assemblies, specifically National Stock Number 1680-01-621-6695, Part Number 3890AS003548-02. This is a sole-source repair opportunity, meaning only specific vendors will be considered.
This is a flight-critical item, which means the quality and reliability of the repair work are paramount. Vendors who can meet the strict engineering source approval requirements will find this a significant opportunity to work with the Navy on essential equipment.
Key dates and what happens at the deadline
This Request for Proposal (RFP) was published on April 16, 2026. The deadline for submissions is August 28, 2026, at 2:00 PM ET. All proposals, including any required source approval requests, must be submitted by this time.
At the deadline, the Navy will review the submitted proposals. For new manufacturers, a pre-award survey and post-award conference may be required. For existing sources, a post-award conference may be recommended.
Who this opportunity suits
This opportunity is specifically for firms that already hold a Basic Ordering Agreement (BOA) N00383-23-G-SX01 with the Navy. Without this existing BOA, a company will not be considered.
Additionally, due to the flight-critical nature of the item, only engineering-source-approved manufacturers are eligible. Companies not previously approved must submit a Source Approval Request with detailed documentation by the solicitation's closing date. This makes it suitable for experienced aerospace or defense contractors specializing in equipment repair and modification, particularly those with a history of working with the Naval Air Systems Command.

Practical tips for a competitive response
Given this is a sole-source repair solicitation and involves flight-critical components, ensure your proposal clearly demonstrates your firm's expertise and adherence to all specified technical requirements. Pay close attention to the marking requirements in accordance with MIL-STD-130, revision level 'L' or the latest revision, and drawing requirements.
If you are a new manufacturer seeking source approval, meticulously prepare your Source Approval Request. This includes providing complete configuration drawings, process/operation sheets, documentation of past production deliveries, a detailed comparative analysis of similar parts, and inspection method sheets. Ensure all aspects of the ASO Source Approval Information Brochure dated January 1995 are addressed, even if only a subset of data is initially requested.
