As of September 2019Minuteman-III missiles are regularly tested with launches from When the Minuteman ICBM was first placed on alert, the Soviet Union did not have the number of weapons, accuracy, nor significant nuclear yield to completely destroy the Minuteman ICBM force during an attack. The Boeing LGM-30A Minuteman I ICBM was the first ICBM to use solid fuel rather than the liquid fuel of its predecessors, the Atlas and Titan Intercontinental Ballistic Missiles. This 17-metre (56-foot), three-staged Development of the Hall's ultimate plan was to build a number of integrated missiles "farms" that included factories, Hall's plan did not go unopposed, especially by the more established names in the ICBM field. This appeared at first to be an insurmountable problem, but in the end, it was solved in an almost trivial fashion. The Soviets would not risk an attack under these conditions.This presented a serious problem for the Air Force. Although Minuteman would not deploy a During Minuteman's early development, the Air Force maintained the policy that the manned Soviet ICBMs upset this equation to a degree. Minuteman I achieved initial operational capability in November of 1962. Boeing's LGM-30G Minuteman III retained the three stages of solid propellant rocket engines. Oct. 24, 1962 - The first Minuteman I missile field went on alert a year ahead of schedule, at Malmstrom Air Force Base, Montana. Northrop won by default, as their bid was at the time the only bid left to be considered for the GBSD program (Boeing had dropped out of the bidding contest earlier in 2019). Autonetics began such development even before the original Minuteman entered fleet service, and the Minuteman-II had a CEP of 0.26 nautical miles (0.48 km; 0.30 mi). Development on the Minuteman-II began in 1962 as the Minuteman-I entered the Strategic Air Command's nuclear force. For the quick launch, the guidance system would have to be kept running and aligned at all times, which was a serious problem for the mechanical systems, especially the gyroscopes which used The last major advance was to use a general-purpose digital computer in place of the analog or custom designed digital computers.

During the 1980s, surplus Minuteman missiles were used to power the Conestoga rocket produced by Space Services Inc. of America. Minuteman-II production and deployment began in 1965 and completed in 1967. Minuteman I Missile A/B.
More recently, converted Minuteman missiles have been used to power the Minotaur line of rockets produced by L-3 Communications is currently using SR-19 SRBs, Minuteman-II Second Stage Solid Rocket Boosters, as delivery vehicles for a range of different re-entry vehicles as targets for the THAAD and ASIP interceptor missile programs as well as radar testing. Their accuracy was known to be low, on the order of 4 nautical miles (7.4 km; 4.6 mi), but they carried large warheads that would be useful against In this environment, the Air Force saw their own ICBMs not as a primary weapon of war, but as a way to ensure that the Soviets would not risk a sneak attack. The newer system extends the service life of the Minuteman missile beyond the year 2030 by replacing aging parts and assemblies with current, high reliability technology while maintaining the current accuracy performance. The Army's Minuteman's selection as the primary Air Force ICBM was initially based on the same "Chief among these qualities was its digital computer. Although lengthy, this was not considered to be a problem at the time, because it took about the same amount of time to spin up the Minuteman was designed from the outset to be launched in minutes. For the subsequent plans for Peacekeeper Rail Garrison and Soviet Scalpel rail basing, see The letter "L" in "LGM" indicates that the missile is Marti and Sarigul-Klijn, A Study of Air Launch Methods for RLVs. The initial cost of these computers ranged from about $139,000 (D-37C) to $250,000 (D-17B). There have been three generations of Minuteman missiles. In any conceivable scenario where both sides had similar numbers of ICBMs, the US forces would survive a sneak attack in sufficient numbers to ensure the destruction of all major Soviet cities in return.

It was the first privately funded rocket, but only saw three flights and was discontinued due to a lack of business. The Minuteman I weighed roughly 65,000 lb (29,000 kg), had an operational range of 5,500 mi (8,900 km)At its introduction into service in 1962, Minuteman I was fitted with the The LGM-30F Minuteman-II was an improved version of the Minuteman-I missile. Through more than 50 years of continuous enhancements, Boeing’s innovations in design, sustainment, maintenance and modernization have ensured the safety, security, and effectiveness of the Minuteman system.The Ground Based Strategic Deterrent (GBSD) is the U.S. Air Force’s intended replacement for the Boeing LGM-30G Minuteman III ICBM weapon system, the land-based, silo-launched backbone of the nuclear deterrence triad.

However, starting in the mid-1960s, the Soviets began to gain parity with the US and now had the potential capability to target and successfully attack the Minuteman force with an increased number of ICBMs that had greater yields and accuracy than were previously available.
