Heller (antitank rocket)

The Heller was a Canadian antitank rocket launcher produced and fielded in the 1950s. The Heller was in production from 1954[1] and remained in service until 1967.[2] The Heller fired a 3.2-inch high explosive antitank projectile that was capable of penetrating 11 inches of rolled homogenous armor when struck at a 90-degree angle of impact.[3] It replaced the US Bazooka, providing both longer range and greatly increased penetration. It was in turn replaced by the US M20 "Super Bazooka" which had even higher performance and somewhat simpler setup, and these were in turn replaced by the 84-mm MAW.
