IAI Nammer

The IAI Nammer (נמר "Leopard") was a fighter aircraft developed in the Israeli aerospace manufacturing Israel Aerospace Industries (IAI) during the late 1980s and early 1990s. The program was pursued as a private venture and the resultant aircraft was intended for the export market.

During the 1980s, IAI decided to embark upon the independent development of a modernised version of the IAI Kfir; reusing its airframe and pairing it with a moderniszd cockpit, engine, and avionics, the latter of which was to have taken advantage of the earlier work undertaken for the cancelled IAI Lavi program. These changes were to result in greater performance, range, and air-to-air combat capabilities than the preceding Kfir. Named Nammer, the aircraft was to be offered under various different configurations, including alternative engines and radars, as well as prospective licensed production arrangements, to customers. IAI stated that they were willing to be highly flexible with the Nammer's launch customers, being open to giving them great leeway over modifying the design and incorporating their own systems as to their preferences.

Development of the Nammer proceeded to the prototype stage; a single aircraft was constructed to function as a proof-of-concept prototype, demonstrating IAI's capability to successfully install and operate advanced avionics in existing airframes, in this case the Mirage III/Kfir. On March 21st 1991, the prototype performed its maiden flight. Following on from its first flight, it continued to be used for test flights for some time, demonstrating both the maturity of the concept and of the new IAI-integrated systems. While the proven delta canard configuration of the airframe had been retained, testing was focused upon the new avionics installed, which were said by IAI to make for a relatively modern fighter aircraft. However, despite the company's lengthy efforts to seek both partner companies and export customers for the Nammer, neither participants in the program nor buyers of the finished product proved to be forthcoming; as such, development of the Nammer was ultimately ceased by IAI during the early 1990s without any further examples having been constructed.
