For more than six decades, a safe, secure, and effective strategic deterrent has served as the bedrock of United States (U.S.) national security. To keep pace with the current threat environment, the U.S. is spearheading a critical modernization of the current land-based leg of the nuclear triad, known as the U.S. Air Force's Sentinel ICBM. 

Historic in scope and complexity, this once-in-a-generation system includes a new missile, a vast command, control, and communications capability, and hundreds of infrastructure projects, including hardened facilities spread across thousands of miles in five states.

This next-generation Sentinel system replaces the current Minuteman III, which has been in service for more than 50 years. Delivering on this capability is a Northrop Grumman-led team responsible for designing and producing the most technologically advanced portion of this new ground-based strategic deterrent, designed to be viable through 2075.
