289:: In 1983, the 60mm HVMS was fitted to M24 Chaffee and M-50 Sherman tanks, which were known at the time, as the M-60 Sherman tanks. It is believed that when the M24 Chaffee's were withdrawn from service in the early 2000s. The 60mm HVMS autocannons was fitted to one prototype M41 Walker Bulldog and one prototype Piranha 6x6 IFV that was trialed. As of 2022, it is uncertain as to whether any vehicles armed with this autocannon remain in active service.

The project commenced in 1977, originally as a joint development between IMI Systems of Israel and OTO Melara of Italy, whereby IMI Systems were expected to develop the gun and ammunition, and OTO Melara the autoloader and a lightweight two-man turret which could be mounted on a variety of different
