After the success of the Learjet 25 series, the company initiated design experiments around 1970, replacing the CJ610 turbojet engine with the TFE 731. This modification resulted in a significant reduction in noise levels and an increase in power. Opting for a new design, Learjet introduced the Learjet 35 instead of creating a variant within the 25 series. The Learjet 35 served as both a business jet and a military transport aircraft, mirroring its successor, the Learjet 36. The C-21 military variant, a modified 35A utilized by the U.S. Air Force, fulfilled roles in passenger and cargo transport, as well as medevac operations. The inaugural model was delivered in 1984 and entered into service the same year.
