The United States Air Force's Rapid Execution and Combat Targeting System (REACT) is a modification of the LGM-30 Minuteman launch control centers (LCC's) that provides continual monitoring and rapid retargeting of Minuteman ICBMs. [1] It integrates communication systems and weapon systems into a single console.
Mobile Minuteman was a program for rail-based ICBMs to help increase survivability and for which the USAF released details on 12 October 1959. Minuteman Mobility Test Trains were first exercised from 20 June to 27 August 1960 at Hill Air Force Base, and the 4062nd Strategic Missile Wing (Mobile) was organized 1 December 1960. It was planned to ...
Minuteman III guidance ring containing the D37D computer. Minuteman III guidance ring on display at the National Air and Space Museum. The D37D Minuteman III flight computer was initially supplied with the LGM-30G missile, as part of the NS-20 navigation system. The NS-20 D37D flight computer is a miniaturized general purpose (serial ...
The first true MIRV design was the Minuteman III, first successfully tested in 1968 and introduced into actual use in 1970. [5] [6] [7] The Minuteman III held three smaller W62 warheads, with yields of about 170 kilotons of TNT (710 TJ) each in place of the single 1.2 megatons of TNT (5.0 PJ) W56 used on the Minuteman II.

W78 warheads are contained inside the MK12-A reentry vehicles of the LGM-30G Minuteman III. Drawing of the Mark 12A re-entry vehicle that houses the W78 warhead. The W78 is an American thermonuclear warhead with an estimated yield of 335–350 kilotonnes of TNT (1,400–1,460 TJ), deployed on the LGM-30G Minuteman III intercontinental ballistic missile (ICBM) and housed in the Mark 12A reentry ...
The Minuteman had a relatively fast launch time, and early warning satellites meant that commanders would have almost instant warning of a Soviet launch, with ample time to plan a response. However, it would not be until much later in the sequence of events that land-based radars would be able to track the incoming individual warheads and ...
The Minuteman I, II and III weighed 29,500 kg, 31,746 kg and 35,000 kg respectively, versus the Soviet R-7 missile (1959) at 280,000 kg. The US planners had to choose either to develop solid state guidance systems (which weigh less) or consider the additional cost and time delay of developing larger rockets.
