CASA C-101 Aviojet

The CASA C-101 Aviojet is a low-wing, single-engine jet advanced trainer and light attack aircraft designed and built by the Spanish company Construcciones Aeronáuticas SA (CASA). It was developed to meet a Spanish Air Force requirement of 1975 for a replacement for the ageing Hispano HA-200 and Ha.220 trainers, with technical help from Germany's Messerschmitt-Bölkow-Blohm, whose engineers worked on the rear fuselage and tail, and the American company Northrop, whose team designed the wings and engine inlets. The first of four prototypes flew in June 1977 and the Spanish Air Force introduced the type into service on 17 March 1980. A tandem two-seat cockpit, an unswept wing, a Honeywell TFE731 turbofan and a large internal weapons bay beneath the rear cockpit characterise the design. Chile, Honduras and Jordan bought it for their air forces, and the Spanish Air and Space Force retired the type in June 2025.
