Douglas M31/M50/MGR-1 Honest John Missile, CF586
- The Douglas M31/M50/MGR-1 was the U.S. Army's first nuclear-armed surface-to-surface rocket.
In late 1950, Douglas was contracted to develop this new rocket. Flight testing began in June 1951, and in January 1953, the first limited-production Honest John rockets, designated Artillery Rocket XM31, reached U.S. Army units. In September 1953, the Honest John was reclassed as M31, and the first operational units were deployed in Europe in Spring 1954.
The M31 was an unguided 762 mm artillery rocket, powered by a M6 solid-fuel rocket engine, and spin-stabilized in flight by two M7 spin motors. It had a range between 5.5 km (3.4 miles) and 24.8 km (15.4 miles).
