A $38 Million Avionics Upgrade For The Fleet Is Underway
After 35 years of C-21 operations, mobility Airmen are celebrating 2019 as the "Year of the Lear” with upgrades for the airframe and changes within the units that fly it. The C-21 is the military version of the Learjet 35A. A $38 million avionics upgrade for the fleet is underway and a consolidation effort is moving four aircraft from Andrews Air Force Base, Maryland, to join Scott AFB’s 10 C-21s by late summer.
