The estimated annual quantity is 40 units. This is a critical item, and the contract will involve delivery and acceptance at the destination.
This opportunity is significant because it establishes a long-term contract for a specific aircraft part. While Lockheed Martin and Arrowhead Products are currently approved sources, other interested companies can become approved by submitting a Source Approval Request.
Key dates and what happens at the deadline
This is a Request for Information (RFI) published on August 06, 2026. The deadline for responses is September 25, 2026, at 3:00 PM ET. The government will consider all proposals received within forty-five days after the publication date of this synopsis.
The solicitation for this contract is expected to be issued on August 24, 2026. After the deadline, the government will review submissions to determine if a competitive procurement is feasible. Information received will primarily be used to decide whether to conduct a competitive process.
Who this opportunity suits
This opportunity is best suited for manufacturers or suppliers with experience in aerospace components, particularly those for military aircraft. Companies that can produce source-controlled items or are willing to go through a Source Approval Request (SAR) process will find this relevant.
The item is a duct, bleed air, for B-1B aircraft, falling under the equipment category. Firms with existing capabilities in manufacturing or supplying similar critical aircraft parts, or those with strong engineering and quality control processes to meet defense standards, are good candidates.

Practical tips for preparing a competitive response
Given that this is a source-controlled item, if you are not Lockheed Martin or Arrowhead Products, focus on preparing a robust Source Approval Request (SAR) package. This package should clearly demonstrate your capability to meet the technical specifications and quality requirements for this critical part.
Ensure your company is registered in the System for Award Management (SAM.gov) well in advance, as this is a mandatory requirement for any award. Pay close attention to all instructions in the solicitation once it is released, and address every requirement thoroughly. The final award decision may consider price, past performance, and other evaluation factors.
