The Neshers' airframe was identical to the Mirage 5, but there was an extensive refitting of Israeli-built avionics systems, along with the adoption of a Martin-Baker zero-zero ejection seat, and improved provisions for a wider range of AAMs (Air-to-Air Missiles), including the Israeli Shafrir heat-seeking missile. In total, 51 Nesher fighters (Nesher S) and ten Nesher two-seat trainers (Nesher T) were constructed by IAI. The Nesher featured more simplistic avionics than the IAF's Mirage IIIC, reportedly, it was also slightly less maneuverable. However, it possessed a longer combat range and a larger payload. The reduced maneuverability of the type did not prevent the Nesher from performing well in air combat during the Yom Kippur War of 1973.
