||The Honest John was a long-range artillery rocket capable of carrying an atomic, HE, or chemical-submunition warhead. The rocket was 27 feet long, 762mm in diameter, weighed 5,800 pounds, used a solid propellant and had a range of 12 miles. It was first fired at White Sands in 1951. In the Spring of 1954 the Honest John was deployed as an interim system. This was the first US tactical nuclear weapon. The Basic (M31) HONEST JOHN system was first deployed in 1954. It was replaced by the Improved (M50) HONEST JOHN in 1961 which reduced the system's weight, shortened its length, and increased its range.
