Magach (Hebrew: מגח, 'battering-ram') is the designation of a series of tanks in Israeli service. The tanks are based on the American M48 and M60 tanks. The name continued to be used for all M48/M60 tanks. Magach 1, 2, 3, 4 and 5 are based on M48 series tanks, and Magach 6 and 7 are based on M60 series tanks. The first M48 Patton tanks acquired by the Israel Defense Forces (IDF) were purchased from West Germany in the early 1960s (M48A2 variant) in a secret arms deal, followed by deliveries from the United States after 1965 (M48A1 and M48A2C vehicles) when Germany cancelled further deliveries after the deal was exposed. During the 1967 war, the Israeli tanks served in their original (American) configuration. Following the 1967 war, several dozen Jordanian M48 tanks, captured intact during the 1967 Six-Day War, were also commissioned into the IDF, adding to the 150 already in service at that time. Israel also modified the tank to M48A3 automotive standard by replacing the 650 hp gasoline engine[citation needed] with a 750 hp diesel one, more powerful and less vulnerable to fuel fires, resulting in the Magach 3. These modifications also included replacing the original 90 mm gun with the British 105 mm L7 (US M68 equivalent), replacing the commander's machine gun cupola with a lower-profile Urdan Cupola, and upgrading the communication suite.
