Aerospace and Defense covers the aircraft, spacecraft, weapons systems and military equipment that public agencies buy, along with the parts, repairs and overhauls that keep them running. Most of it comes from the Department of Defense, which posts a steady stream of orders for individual components such as actuators, generators, seals and access covers, often identified only by a part or stock number. NASA also appears here, with larger research and space contracts and technology licensing notices.
Many defense parts orders are small, fast Requests for Quotation where the buyer names an approved part and awards on price and delivery, sometimes limited to qualified or approved sources. Repair and overhaul work often requires a quality system and the ability to meet the stated specification. Larger programs run through Requests for Proposals that score technical approach and past performance, and export-control and security rules can apply to who may bid.
This page lists open aerospace and defense bids from federal, state and local buyers, soonest closing first, then recently closed solicitations and contract awards. Past awards show which parts and repairs recur, how often they come back out, and which suppliers tend to win them.
