Ecuador
In 1981, Ecuador and Israel signed a sales agreement for ten refurbished ex-IAF Kfir C.2s and two TC.2s, which were delivered to the Ecuadorian Air Force (FAE) in 1982–1983. The Kfirs formed the 2113rd Squadron (Lions) of the FAE's 21st Fighter Wing, based at Taura AFB, on the Ecuadorian western lowlands.
The FAE Kfirs went into action during the 1995 Cenepa War between Ecuador and Peru. Relying on its fleet of subsonic A-37Bs for low-level ground-attack missions on Peruvian positions, the Ecuadorian Air Force held back its Mirage F.1s and Kfir C.2s for use as escorts and interceptors. On February 10, 1995 a Kfir C.2 shot down a Peruvian Air Force Cessna A-37B with a Shafrir 2 IR-homing AAM.
In 1996, with tensions still running high between Ecuador and Peru, the Ecuadorians acquired four additional Kfirs (three C.2 and one TC.2) after securing approval from the U.S. State Department.
In 1998, with its aging squadron of SEPECAT Jaguar fighter-bombers about to be withdrawn from active duty, Ecuador began talks with Israel for the sale of a new batch of eight Kfirs. Fearing an escalation of the arms race in South America – Peru had recently acquired 18 MiG-29s and 18 Su-25s from Belarus – the United States blocked the deal. As an alternative, Ecuador and Israel signed an agreement in 1999 for the delivery of two Kfir C.10s and for the conversion of an undisclosed number of the FAE's original C.2s to the C.10 version, referred to in Ecuador as Kfir CE, featuring a Helmet Mounted Display System, and armed with Python 3 and Python 4 IR-homing AAMs.
By 2005, Ecuador had lost four Kfirs, including one TC.2, due to accidents since the aircraft entered service in 1982.
