* What We Do:

*
* Guidehouse supports the Department of War in modernizing, operating, and sustaining the mission. Our teams blend program management, engineering, cyber, and financial expertise to manage cost and schedule, integrate complex systems, and strengthen readiness-so leaders can make faster decisions and provide decisive support to the warfighter. Core competencies span acquisition and program management; systems engineering and integration (including MBSE, T&E, and configuration control);

digital engineering, data, and AI; cybersecurity and zero trust (RMF/ATO acceleration and supply‑chain security); financial management and cost (PPBE, cost estimating, audit readiness, and performance management); logistics, sustainment, and readiness (predictive maintenance and supply‑chain resilience); risk, compliance, and mission assurance; change management and workforce transformation; and strategic communications and stakeholder engagement.

We bring a global footprint across North America, Europe, the Middle East, and Asia‑Pacific, with secure delivery centers, cleared practitioners, and a flexible consulting‑plus‑digital‑plus‑managed‑services model that scales to mission needs. Within the Department of War, we support headquarters elements, PEOs/PMs, major commands, defense agencies, and joint organizations-covering mission areas such as acquisition and portfolio governance, C4/cyber and zero‑trust transformation, test and evaluation, sustainment and logistics, finance/comptroller and audit, medical readiness, and installations and infrastructure.

Our teams operate CONUS and OCONUS with on‑site presence at key program offices and installations, augmented by hybrid and surge capacity, to ensure resilient delivery and measurable outcomes.

Guidehouse Aerospace Professionals will support ICBM Development, Operations & Sustainment (IDOS) and the entire ICBM enterprise-end to end across development, operations, and sustainment. The Sentinel program is a once‑in‑a‑generation recapitalization of the U.S. intercontinental ballistic missile (ICBM) enterprise-replacing the Minuteman III weapon system while sustaining Minuteman III readiness throughout the transition to ensure uninterrupted strategic deterrence. Spanning a multi‑state footprint, the effort modernizes launch, support, and security infrastructure;

fields a newly designed, technologically advanced missile; and delivers a modern, end‑to‑end command‑and‑control architecture, including updated airborne launch capability. This role focuses on comprehensive support across acquisition strategy and execution; requirements development and interface integration; cost, schedule, risk, and configuration management; and nuclear surety and cybersecurity compliance. Equally critical, it strengthens Minuteman III sustainment via life‑extension planning to maintain safety, reliability, and mission availability during Sentinel fielding.

Initial fielding is expected to begin in the late 2020s with deployment over approximately nine years, enabling sustained operations through at least 2075.
