The Modern Mission
Designed for the future of land-based strategic deterrence, the Mk21A is Lockheed Martin's next-generation integrated reentry vehicle engineered to deploy the W87-1 warhead aboard the U.S. Air Force's Sentinel ICBM.
Adapted from the Mk21 reentry vehicle, our mature design uses advanced digital engineering tools, including advanced modeling and simulation to validate at unprecedented speed.
These complex reentry vehicle systems must be able to travel at high speeds, resist heat and are guided by electronics to accurately deliver a payload. We bring decades of experience designing, developing, testing and producing reentry vehicles for the U.S. Air Force and are now working on a Technology Maturation and Risk Reduction (TMRR) contract to design Mk21A.

Using a digital engineering approach, we’re developing resilient solutions designed for our customers’ needs and delivering when and where they need it
Committed to exceptional program performance
For more than 65 years, Lockheed Martin has partnered with the U.S. Air Force to pioneer, build and sustain America’s ICBM deterrent. Beginning with the historic 1955 Atlas program, which produced the nation’s first operational ICBM in 1959, we have delivered more than 700 missiles and 3,000 reentry vehicles across the Atlas, Titan, MX Peacekeeper and Small ICBM families, while maintaining critical command and control systems for Minuteman III.
Today, that deep operational experience fuels the next generation of strategic deterrence. By pairing proven technologies with innovative support equipment, we enable the Air Force to test, maintain and modernize its strategic force.
From those first launches to supporting today’s Sentinel ICBM program, we equip warfighters with end-to-end readiness and reliable capability.
