NAVSUP Weapon Systems Support Philadelphia is conducting market research to identify eligible sources able to furnish labor, material, and facilities to produce the Exhibit A items supporting the F/A-18 aircraft. The government intends to add these items to an existing requirements contract and award sole-source to Honeywell International Inc. under FAR 6.103-1. Responsible sources may submit capability statements or proposals, but this is not a request for competitive proposals and the government retains discretion not to compete. Source approval is required, and award will not be delayed pending approval of a new source; non-approved sources must submit the required Source Approval Information Brochure for Repair information with their proposal.
