Confirma, Confirma.
Their combat radius is a bit short, and it would take a brave Kfir pilot to face a Eurofighter Typhoon in single combat. Even so, they’re capable fighters with aerial refueling capability, which makes them well suited to intimidation and presence patrols. Negotiations for a sale are in an advanced stage.
The good news for Britain, such as it is, is that Argentina still has to hang weapons on any fighters they buy. The FAA must either stick with their existing set of old equipment and forego most of the new fighter’s potential, or buy new weapons from the USA or Israel. Any new weapon sales would be a double escalation, making those sales less likely. The most dangerous Kfir-related sale, of Gabriel 3 anti-ship missiles, would make Britain an outright enemy of Israel’s. That won’t happen. The question is whether Britain can pressure Israel to block the Kfir fighter sale in toto – or have it blocked by the Americans, who control the J-79 engines.
If the Israeli sale falls through for some reason, South Africa has already sold similar Cheetah fighters to Ecuador and Chile. Enough were produced to sell 18 more to Argentina, but the best airframes have presumably been taken already. Cheetahs are powered by French Snecma Atar 9K50 engines, instead of the Kfir’s American J-79. That removes a key American veto, but it also means that South Africa would need some level of French cooperation. Given French delays and demurrals around refurbishing Argentina’s French Super Etendards, that cooperation could become problematic.
