Guidehouse has been awarded the United States Air Force's Intercontinental Ballistic Missile (ICBM) Integration Support Contract (ISC) 2.0. This single-award contract has a period of performance of 18 years and ceiling of $12 billion, covering support to the current land-based ICBM, the Minuteman III, as well as its replacement, the Sentinel. The contract scope covers a broad range of systems engineering and integration services, including administration, business analysis, cybersecurity, engineering, digital engineering, finance, integration, mission effectiveness, nuclear surety, program management, research, risk management, science, strategy development, sustaining engineering, systems engineering, system safety and security, and technical assessments. For ISC 2.0, Guidehouse assembled a purpose-built team of the best companies in industry and a consortium of leading universities to bring depth and breadth of scale from solving some of the DoD's most complex challenges, including the expertise of being an Air Force and Department of Defense leader in systems integration, acquisition, program management, sustainment, cybersecurity, and innovation.

Guidehouse has supported over a dozen Air Force programs across 5 Program Executive Offices, helping to solve the same types of sustainment, acquisition, development, and transition challenges facing Minuteman III and Sentinel. The shift from Minuteman III to Sentinel will transition 400 combat-capable nuclear missiles and support infrastructure over nearly a decade without any degradation of mission readiness?one of the most complex weapon systems fielding efforts ever in the nation's history. During this transition, the Minuteman III weapon system must be sustained to achieve the same high availability sortie alert status it has demonstrated for the past fifty-plus years, while addressing ongoing challenges such as diminishing sources of manufacturers, obsolescence, and aging. Through this contract, Guidehouse's staffing is expected to begin with nearly a thousand full-time employees on-site at Hill Air Force in Ogden, Utah and at Guidehouse's new office near the base in Clearfield.
