Its designation was changed to M31 in September 1953. The first Army units received their rockets by year's end and Honest John battalions were deployed in Europe in early 1954. Alternatively, the rocket was capable of carrying an ordinary high-explosive warhead weighing {{convert|1500|lb}}. History and developmentDeveloped at Redstone Arsenal, Alabama, the Honest John was a large but simple fin-stabilized, unguided artillery rocket weighing {{convert|5820|lb}} in its initial M31 nuclear-armed version. Mounted on the back of a truck, the rocket was aimed in much the same way as a cannon and then fired up an elevated ramp, igniting four small spin rockets as it cleared the end of the ramp. The M31 had a range of {{convert|15.4|mi}} with a 20 kiloton nuclear warhead and was also capable of carrying a {{convert|1500|lb|adj=on}} conventional warhead. The M31 system included a truck-mounted, unguided, solid-fueled rocket transported in three separate parts. The Honest John was assembled in the field before launch, mounted on an M289 launcher, and aimed and fired in about 5 minutes. The rocket was originally outfitted with a W7 nuclear warhead, with a variable yield of up to {{convert|20|ktonTNT|lk=on}}; in 1959, a W31 Early tests exhibited more scatter on target than was acceptable when carrying conventional payloads. Development of an upgraded Honest John, M50, was undertaken to improve accuracy and extend range. The size of the fins was greatly reduced to eliminate weathercocking. Increased spin was applied to restore the positive stability margin that was lost when fin size was reduced. The improved M50, with the smaller fins and more "rifling", had a maximum range of 30+ miles with a scatter on target of only {{convert|250|yd}}, demonstrating an accuracy approaching that of tube artillery. The Honest John was manufactured by the Douglas Aircraft Company of Santa Monica, California.[2] In the 1960's, sarin nerve gas cluster munitions were also available, designed to be interchangeable for use with either the Honest John or MGM-5 Corporal. Initially the M79 (E19R1) GB cluster warhead, containing 356 M134 (E130R1) bomblets for the M31A1C Honest John. The production model was the M190 (E19R2) GB cluster warhead, containing 356 M139 (E130R2) bomblets when the M31A1C was phased out in favor of the XM50 Honest John. Under nominal conditions it had an mean area of effect of 0.9 square kilometers.[3] VariantsThe two basic versions of Honest John were:
Production and deploymentProduction of the MGR-1 variants finished in 1965, with a total production run of more than 7,000 rockets. The Honest John's bulbous nose and distinctive truck-mounted launch ramp made it an easily recognized symbol of the Cold War at army bases worldwide and National Guard armories in the U.S.. Even though it was unguided and the first U.S. nuclear ballistic missile, it had a longer service life than all other U.S. ballistic missiles except the Minuteman system. The system was replaced with the MGM-52 Lance missile in 1973, but was deployed with the National Guard units in the United States as late as 1983. Conventionally armed Honest Johns remained in the arsenals of Greece, Turkey and South Korea until at least the late 1990's. By the time the last Honest Johns were withdrawn from Europe in the late '80's (and replaced by the unguided M-26 artillery rocket), the rocket had served with the military forces of Belgium, Britain, Canada, Denmark (non-nuclear), France, Germany, Greece, Italy, the Netherlands, Norway (non-nuclear), South Korea, Taiwan (non-nuclear), and Turkey.[5] Name originIn late 1950, Major General Holger Toftoy was a colonel overseeing the development of the rocket. The project was in danger of cancellation "on the grounds that such a large unguided rocket could not possibly have had the accuracy to justify further funds."[6] On a trip to White Sands Missile Range, Toftoy met a Texan man who was prone to making unbelievable statements. Whenever anyone expressed doubt about the man's claims, he would respond, "Why, around these parts, I'm called 'Honest John!'" Because the project was being questioned, Toftoy felt that the nickname was appropriate for the rocket and suggested the name to his superiors.[6] Support vehiclesVehicles used with the Honest John platform:

Used in various Corps and Divisional artillery units (75, 3, 20 and 14th Artillery Battalions) from 1960 to 1978. Replaced by Lance missile.
Canada adopted the MGR-1B with the 1-kiloton W31 warhead. Four units were assigned to 1 Surface to Surface Missile Battery, Royal Canadian Artillery at Hemer, Germany under 4 CIBG. Two to four units were supplied to 2 SSM Battery at CFB Shilo in Manitoba for training. These units were formed in September 1960. 1SSM maintained very high readiness and able to deploy to firing positions quickly. Their ability to maintain camouflage kept even elite NATO special forces from locating them in exercises. 1SSM was authorized to wear the black scarf of the Congreve rocket gunners. Canada disbanded the Honest John batteries in mid-1970 without replacement.[10][11]
