Israeli HVMS (Hyper Velocity Medium Suppor) 60mm gun (as on M113 HVMS APC) was fitted in Sherman tanks that Israeli supplied to Chilean army. The HVMS gun was a small 60mm gun that provided high velocity kinetic energy projectiles to penetrate unheard of amounts of armour at considerable ranges.
 

Chile acquired from Israel 50 units of M-51 in the 1970s and 1980s, with a total of 50 units. These tanks arrived at Chile with 75mm gun (the same one installed in the AMX-13) that replaced later in 1980s by the new 60mm HVMS gun of hypervelocity. The trajectory of the projectile is so tense that it does not require of systems of fire control falsified, ademas of the substitution by a new motor, these tanks with the new 60mm HVMS gun were the answer to the T-55 Peruvian in the almost happened situation.

In 1983 Chile acquired a number of M-50s from Israel as well. By mid 1984, they had arrived without their 75 mm guns. The M-50s were fitted with a 60mm HVMS gun by the Chilean national arms industry at Fuerte Arteaga. This modification was developed by NIMDA Co. Ltd. of Tel Aviv, Israel. Although as many as 50 to 65 M-50s were acquired, 48 are now on strength. 
They have a prominent engine exhaust on the rear deck.

Now Chilean army in its plan of modernization maintains along with the new tanks in good condition to them leopard 1v acquired to single Holland and terminating M-51 and mount their 60mm HVMS gun on armored Piraña 6x6.



M-60 is an Israeli modification of the M-50 and M-51 variant of the Sherman main battle tanks. In this version, the French gun is replaced by a 60mm HVMS gun, for use as a heavy support vehicle, and the engine is replaced with a variant of the same engine used in the Stingray tank.

Israeli HVMS (Hyper Velocity Medium Support) 60mm gun (as on M113 HVMS APC) was fitted in Sherman tanks that Israeli supplied to Chilean army. The HVMS gun was a small 60mm gun that provided high velocity kinetic energy projectiles to penetrate previously impenetrable armor at considerable ranges.
