Shot Kal Alef (United Nations, Tier-9, MT, techtree)
In the late 1950s, the Israel Defense Forces (IDF) acquired several British Centurion Mk. 5 tanks, which were designated Shot (meaning “whip”) in Israel. Deliveries of these tanks continued, eventually bringing the total number of Shot tanks in service to over a thousand.
Their operational experience, both in peacetime and during the Six-Day War of 1967, revealed numerous design flaws that could not be rectified with minor modifications. After evaluating possible solutions, a comprehensive modernization program was developed. This upgrade included replacing the gasoline engine with a diesel one, installing an automatic transmission, fitting a new gun, redesigning the engine compartment, and improving crew conditions. This modernization resulted in the Shot Kal Alef.
