DF Shot Kal Alef (1973) – Shot Kahl is the Israeli name for the English Centurion tank, which was in service with the land forces of the Israeli Defense Forces (IDF or IDF). In Hebrew, Shot means "scourge", or "whip", Shot Kahl – "light whip", besides "kal" is a slang term from the name of the engine "Continental", installed on modernized tank models. The first tanks Centurion (second-hand models Mk.3 and 5, as well as new Mk.7 and Mk.8) came to Israel in 1959. The six-day war showed the weakness of the gun and engine, a small power reserve and other shortcomings. Modernization of the Shot tanks began in 1969, at the Israeli tank repair plant: the English gasoline engine of water cooling "Meteor" was replaced with the American diesel "Teledain Continental" with air cooling.
The mechanical transmission was replaced with hydro-mechanical transmission of the "cross-drive" type "Allison" CD850-6.
The engine room was recomposed for a new engine cooling system.
Armored air filters were installed on the above-the-shelf shelves.
The electrical system of the tank was replaced.
Head lights were modernized.
Modernization was designed to increase mobility, power reserve, simplify control, and reduce fire risk, by switching to diesel fuel. In addition, the new diesel engines had a much greater service life than the outdated English "Meteors". The tank ammunition increased to 72 shots.
Modernized tanks were named Shot Kahl, unmodernized unofficially began to be called "Shot Meteor."
