AAR Corp Space

AAR Corp is a Wood Dale, Illinois-based aviation and aerospace services company founded in 1951 (NYSE: AIR) that provides maintenance, repair, and overhaul (MRO) services, parts supply, logistics, and aircraft modifications to commercial airlines, cargo operators, and government/defense customers globally. While AAR's primary business is commercial aviation MRO — one of the largest independent aviation MRO providers in the United States — the company's capabilities in aerospace components, supply chain logistics, and government contracting extend into space and defense program support.

AAR supports government aerospace programs including logistics services, component repair and overhaul, and supply chain management for military aircraft programs that share technologies with spacecraft and launch vehicles. The company's government services division holds contracts with the U.S. Air Force, Navy, and Army for aircraft maintenance and parts support, with supply chain capabilities that include space-grade hardware distribution and component traceability documentation required for space flight hardware.

AAR's Parts Supply division manages one of the largest inventories of new, overhauled, and serviceable aerospace components in the industry, including avionics, landing gear, hydraulics, and structural parts. For space programs, this supply chain expertise translates to procuring flight-certified hardware, managing long-lead procurements, and providing distribution for components with space-rated qualifications. AAR also provides Integrated Solutions — long-term government contractor logistics services — which can encompass space ground equipment maintenance and supply management.

The company generates approximately $2 billion in annual revenue and employs 6,000+ people across 14 locations in the U.S. and international facilities. While not primarily a space company, AAR's position as a critical aerospace supply chain and MRO provider means its logistics infrastructure touches space programs through component sourcing, repair, and government program support. AAR competes with Heico Corporation, TransDigm Group, and StandardAero in the aerospace parts supply and MRO services market.
