This improved yield, which had the effect of greatly lowering production costs, and had enormous spin-off effects in the electronics industry. The LGM-30 Minuteman is a U.S. land-based intercontinental ballistic missile (ICBM), in service with the Air Force Global Strike Command. Each flight consists of ten unmanned launch facilities (LFs) which are remotely controlled by a manned launch control center (LCC). The Army argued that upgraded Soviet missiles might be able to attack US missiles in their silos, and Zeus would be able to blunt such an attack. The Air Force began to offer a number of reasons why the bomber offered value, in spite of costing more money to buy and being much more expensive to operate and maintain. Zeus was expensive and the Air Force said it was more cost-effective to build another Minuteman missile. The Minuteman was deployed with a circular error probable (CEP) of about 1.1 nautical miles (2.0 km; 1.3 mi), but this had improved to about 0.6 nautical miles (1.1 km; 0.69 mi) by 1965. Unlike most of its predecessor ICBMs such as Atlas and Titan I, Minuteman can be launched very quickly because of its solid-fuel rocket motor. Download Image of A Minuteman III launch. An unarmed Minuteman III intercontinental ballistic missile launched during a developmental test Wednesday, Feb. 5, at 12:33 a.m. Pacific Time from North Vandenberg. It suggested that Polaris negated any need for Air Force ICBMs if they were also being aimed at Soviet cities. (p153), Hall's ultimate plan was to build a number of integrated missiles "farms" that included factories, missile silos, transport and recycling. 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 ball bearings.

A launch control center (LCC), in the United States, is the main control facility for intercontinental ballistic missiles (ICBMs). During the Kennedy/McNamara cutbacks, the DoD announced "that it has abandoned the plan for a mobile Minuteman ICBM. (pp160–161), Using a general-purpose computer also had long-lasting effects on the Minuteman program and the US's nuclear stance in general. Diagram depicting the different stages of a Minuteman III missile path from launch to detonation, as well as the different basic stages of the missile themselves. This suggested that there was a "finite deterrent" level around 400 megatons that would be enough to prevent a Soviet attack no matter how many missiles they had of their own. September 1964 und einer Minuteman-III am 16. (p199) Reversing the problem, the addition of ICBMs to the US Air Force's arsenal did not eliminate the need, or desire, to attack Soviet military targets, and the Air Force maintained that bombers were the only suitable platform in that role. This theory motivated SAC to design a survivable means to launch Minuteman, even if all the ground-based command and control sites were destroyed. (p160), Since the guidance computer would be inactive while the missile sat in the silo, the same computer was also used to run a program that monitored the various sensors and test equipment. 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 Hercules M57 third stage of Minuteman-I and Minuteman-II had thrust termination ports on the sides. , The Minuteman Missile National Historic Site in South Dakota preserves a Launch Control Facility (D-01) and a launch facility (D-09) under the control of the National Park Service. VANDENBERG AFB: Rank has its privileges, as I was reminded last night when our bus was waved ahead of … It was first deployed in 1970. These newer missiles were later deployed into modified Minuteman silos. The increased burn rate meant increased thrust. The Air Force said the launch was a test of its aging Minuteman III fleet. “Together we make up a weapon system that stands on continuous alert, defending the United States and our allies 24/7, just as we have for the last 50 years.”.  The new missile to be phased in over a decade from the late 2020s are estimated over a fifty-year life cycle to cost around $86 billion. Beginning in 1998 and continuing through 2009, the Propulsion Replacement Program extends the life and maintains the performance by replacing the old solid propellant boosters (downstages). The US Air Force said: "The Air Force will proceed with an aggressive and effective sole-source negotiation." Folds is deputy commander of the 91st Operations Group, whose three squadrons are responsible for manning the wing's 15 Minuteman III launch control centers. In 1970, the Minuteman-III became the first deployed ICBM with multiple independently targetable reentry vehicles (MIRV): three smaller warheads that improved the missile's ability to strike targets defended by ABMs. BARKSDALE AIR FORCE BASE, La. At its introduction into service in 1962, Minuteman I was fitted with the W59 warhead with a yield of 1 Mt. (p156), Minuteman was designed from the outset to be launched in minutes. Even though the Minuteman ICBMs would have been left unscathed in their missile silos following an LCC decapitation strike, the Minuteman missiles could not be launched without a command and control capability. Blind bombing accuracy on the order of 1,500 feet (0.46 km) was expected, and the weapons were sized to ensure even the hardest targets would be destroyed as long as the weapon fell within this range. The joint crew of the E-6B launched the Minuteman III from a silo at Vandenberg Air Force Base in California using the aircraft's Airborne Launch Control System (ALCS) at … Chief among these qualities was its digital computer. The missile fired at 8,000 ft (2,400 m), and the 10-second engine burn carried the missile to 20,000 feet again before it dropped into the ocean. These ports, when opened by detonation of shaped charges, reduced the chamber pressure so abruptly that the interior flame was blown out.

These were delivered in the Mark 12A reentry vehicle. (p160), Building a computer with the required performance, size and weight demanded the use of transistors, which were at that time very expensive and not very reliable. In 1962, the Air Force announced that that Grand Forks AFB would be first to deploy the new LGM-30F Minuteman IImissile (The previous deployments were all Minuteman I). Rapid success in the solids development program, combined with Edward Teller's promise of much lighter nuclear warheads during Project Nobska, led the Navy to abandon Jupiter and begin development of their own solid-fuel missile. :13, Faced with only a few Minuteman LCC targets, the Soviets could have concluded that the odds of being successful in a Minuteman LCC decapitation strike were higher with less risk than it would have been having to face the almost insurmountable task of successfully attacking and destroying 1000 Minuteman silos and 100 Minuteman LCCs to ensure Minuteman was disabled. An Air Force Global Strike Command unarmed Minuteman III intercontinental ballistic missile launches during an operational test at 12:27 a.m. … About 7,000 mi (11,000 km) (Minuteman-II). Each of the bases had 150 missiles emplaced; F.E. Since there was no system to detect the ICBMs being launched, the possibility was raised that the Soviets could launch a sneak attack with a few dozen missiles that would take out a significant portion of SAC's bomber fleet.
