The Aero L-59 Super Albatros is a Czech military trainer aircraft developed from the firm's earlier L-39 Albatros. Compared to its predecessor, it featured a strengthened fuselage, longer nose, a vastly updated cockpit, advanced avionics (including head-up display), and a more powerful engine. At the time of its first flight on 30 September 1986, it was designated the L-39MS. Aero no longer produces this aircraft.
In 1992, a dedicated single-seat attack variant was proposed under the project name ALCA (Advanced Light Combat Aircraft), and was successfully marketed to the Czech Air Force. First flight of this variant, designated L-159A, was on 2 August 1997. The aircraft features mostly Western avionics, with systems integration undertaken by Boeing. Since then a new two-seat trainer has been flown as the L-159B Albatros II.
