When government or commercial organizations need special-purpose aircraft and aircraft systems, AGC Integrated Defense Group designs, integrates, operates and supports mission specific products that add value and operational capability when and where needed.  Integrated Defense companies perform FAA Part 145 maintenance, repair, and overhaul (MRO); provide high quality training to support the operation and maintenance of specialized aircraft and systems; and deliver turnkey solutions for demanding customers.


Headquartered in Oklahoma City, CAT designs, installs and supports high-quality improvements to aircraft. In the beginning, CAT specialized in modifications to the King Air family of aircraft, increasing their rate of climb, cruise speed and payload, while decreasing fuel burn. We expanded that capability to include modifications to government aircraft to enable intelligence, surveillance and reconnaissance missions.

CAT responds quickly to deliver turnkey products and systems to customers around the globe.

Valair performs a wide array of high-quality aircraft maintenance, modification and repair services—all in-house—making it a one-stop facility for aviation customers. Centrally located in Oklahoma City, we are an ISO 9001-registered, FAA Part 145 repair station. For customers stranded elsewhere, we can dispatch a team within hours to their location, fully equipped to get them flying again. Through our specialized avionics facility, we install and service avionics equipment for aircraft ranging in size from single-engine to large corporate jets.
