Strategic Missile Systems


Boeing physically integrated the Minuteman weapon system and has been the U.S. Air Force ICBM Guidance, Navigation and Control (GN&C) system integration contractor for 50+ years on MM I-II-III, including the recent Guidance Replacement Program (GRP); Peacekeeper and Small ICBM. Boeing provides full life-cycle support for Minuteman Guidance including performing troubleshooting and repair of the guidance system at Boeing Heath. As a member of the U.S. Air Force's ICBM Prime Integration team, which is led by Northrop Grumman Mission Systems, Boeing provides sustaining engineering, modifications, and upgrades for the United States ICBM fleet. Boeing's innovative engineers and scientists are at work defining future options for more secure operations and maintenance, increased system effectiveness (accuracy) and continued nuclear surety/safety.

Boeing also leads a team creating concepts for a Conventional Prompt Global Strike (CPGS) capability that relies on a flight-proven hypersonic configuration and is a key technology in any future operational system.

This critical weapon system fills a mission need to strike any target, worldwide from CONUS, with conventional munitions, within one hour of launch. Technologies that enable this weapon system are a robust and stable hypersonic payload delivery vehicle, long duration hypersonic Thermal Protection System (TPS), flight control, precision strike, responsive infrastructure, and streamlined mission planning.

Boeing Strategic Missile Systems has completed testing an advanced dual-layer thermal protection system under a contract to the U.S. Air Force Space and Missile Systems Center. Based on five years of Boeing-financed research, the project leverages ongoing development of hypersonic strike vehicle designs, technologies and concepts of operation for conventional strike missile missions. The thermal protection system allows the vehicle to withstand extreme aerothermodynamic heating and reduces heat buildup by 40 percent to 50 percent compared with other existing thermal protection materials.

Strategic Missile Systems also include the following:

  • Boeing -- Heath, Ohio -- provides repair and final assembly capability for ICBM and DoD aircraft GN&C and antenna systems.
  • Guidance Applications Programs (GAP) -- explores new technologies to extend the life of the Minuteman III missile guidance system.
  • Guidance & control sustainment -- provides assessment and engineering support for Minuteman III guidance systems.
  • ICBM Prime Integration team (Boeing is largest member company) led by Northrop Grumman -- accomplishes Minuteman III sustainment.
  • Trainer contractor logistics support (CLS) -- includes total CLS for all ICBM trainers.
  • Weapon & ground systems sustainment -- includes weapon system test and hardware replacement needed to keep the Minuteman system viable for the foreseeable future.
  • Little Mountain Test Facility -- Boeing operated and maintained nuclear hardness test facility.
  • Field services -- system modification deployment across the Minuteman force.
