This was the first production model of the 3.5 inch anti-tank rocket, manufactured in Italy beginning in 1953. Developed by the U.S. Army, the 3.5 inch rocket, also called the Super Bazooka or M20, was an improvement over the famous 2.36 inch caliber Bazooka anti-tank rocket used during World War II. It was furnished to the Royal Australian Army and other allies during the Korean War, including the Italians who manufactured the weapon at the Boshi Cinelli S.p.A. plant in Florence.
Besides tanks, the M20 was used against stationary targets like bunkers. It had greater penetration than the original Bazooka. Its effective range was 150 yards and maximum range 960 yards.
The U.S. Army Ordnance Museum transferred the M20 to the National Air and Space Museum in 1989.
