GAT Wins $32M Contract To Upgrade USAF Learjets
The C-21A jets, which are the military version of Learjet 35As, will receive ADS-B Out, FANS 1/A, and electronic flight information systems from GAT.

Wichita-based Global Aviation Technologies (GAT) has received the first of 19 U.S. Air Force Learjets that it will update with new avionics. The C-21As, which are the military version of Learjet 35A, will receive ADS-B Out, FANS-1/A and electronic flight information systems so the aircraft can operate under NextGen. GAT will hire additional aircraft mechanics and avionics technicians by the end of the year to accommodate this project.
