The IAI Lavi was a single-engined 4th generation fighter developed in Israel in the 1980s. Developed by Israel Aircraft Industries (IAI), the choice to develop the Lavi was controversial, both with the Israeli public due to the enormous associated costs and particularly with the U.S. government due to competition with American fighters on the export market. These issues led to its ultimate cancelation.
The Lavi was planned to be the mainstay of the Israeli Air Force, and considerable export sales for the aircraft had been forecast. The uniqueness of its design was in the combination of a small, aerodynamic, highly maneuverable plane, with sophisticated, software-rich systems, low armed drag, and the ability to carry a large payload at high speed and over long distances. As of 2012, two of the prototypes have been preserved, and have been on public display.
