Retained exact section · Minuteman III (LGM-30G); explicit variant facts and lead
The LGM-30G Minuteman III program started in 1966 and included several improvements over the previous versions. Its first test launch took place on August 16, 1968. It was first deployed in 1970. Most modifications related to the final stage and reentry system (RS). The final (third) stage was improved with a new fluid-injected motor, giving finer control than the previous four-nozzle system. Performance improvements realized in Minuteman III include increased flexibility in reentry vehicle (RV) and penetration aids deployment, increased survivability after a nuclear attack, and increased payload capacity. The missile retains a gimballed inertial navigation system .

The Guidance Replacement Program replaces the NS20A Missile Guidance Set with the NS50 Missile Guidance Set. 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 replacement program was completed 25 February 2008.
By the 1970s, 1,000 Minuteman missiles were deployed. This force had shrunk to 400 Minuteman III missiles as of September 2017 , deployed in missile silos around Malmstrom AFB , Montana ; Minot AFB , North Dakota ; and Francis E. Warren AFB , Wyoming . The Minuteman III will be progressively replaced by the new LGM-35 Sentinel ICBM, to be built by Northrop Grumman , beginning in 2030.
