U.S. Builds New B-21 Raider Weapons Facility at Whiteman for B-2 Bomber Transition

The U.S. Army Corps of Engineers awarded K & K Industries a $13.65 million contract to build a facility for the B-21 weapons release system at Whiteman Air Force Base. The project will add dedicated support capacity as Whiteman prepares to operate the B-21 Raider alongside the B-2 Spirit during the transition.
The new facility will provide dedicated space to store and support B-21 armament-related equipment while allowing Whiteman to continue B-2 operations without competing for existing infrastructure. Scheduled for completion on March 31, 2028, the project will help the base sustain weapons handling and aircraft support as the Raider is introduced alongside the current stealth bomber fleet.

The project goes beyond the construction of a basic logistics building. U.S. Air Force documentation states that Whiteman currently lacks sufficient space to accommodate all of the munitions-related parts and equipment expected to arrive with the B-21. That constraint becomes more important during the transition period because the base will have to support two stealth bomber fleets in parallel. The new facility is therefore intended to store and test armament-system accessories while freeing existing space needed to sustain B-2 activities.
According to a U.S. Department of War bulletin published on September 21, 2026, the contract awarded to K & K Industries is valued at exactly $13,649,923, with a cumulative announced value of $14,993,485. The Kansas City District of the U.S. Army Corps of Engineers is responsible for the contract, and construction will take place in Knob Noster, Missouri. The project includes a new 1,580-square-meter weapons and release-system shop as well as alterations covering another 674 square meters. The work also includes utilities, communications, access routes, site preparation and cybersecurity measures associated with the building control systems.
Its proximity to the flight line reflects a direct operational requirement. Equipment associated with weapons release systems must be moved efficiently between storage areas, maintenance shops and aircraft being prepared for missions. For a strategic bomber force, that organization has a direct effect on sortie generation. It also reduces dependence on shared facilities at a time when maintenance teams will have to manage the requirements of the B-2 alongside those of a new aircraft with different support and weapons-integration procedures.
Developed by Northrop Grumman, the B-21 uses a flying-wing configuration similar in principle to that of the B-2, with additional emphasis on reducing radar signature and the use of radar-absorbing materials. Its design also relies on an open architecture intended to simplify the integration of new capabilities throughout the aircraft’s service life. Available data indicate a crew of two, a wingspan of about 44.5 meters and an estimated maximum range of close to 12,000 kilometers. The aircraft is also described as using an architecture combining multi-sensor fusion, electronic warfare and networked combat systems. Several parameters, including the exact engine configuration, payload and some flight performance figures, remain poorly documented in public sources or are still based on estimates.
The Raider is intended for long-range conventional strike and nuclear deterrence missions in environments where modern air-defense systems make the use of less stealthy aircraft more restrictive. The U.S. Air Force expects it to employ a range of stand-off and direct-attack weapons, while its open architecture is designed to support the integration of new sensors, software and munitions as requirements change. For Whiteman, having facilities able to test and prepare weapon-system equipment can reduce the time between maintenance, loading and the return of an aircraft to operational status. The infrastructure therefore contributes directly to the base’s ability to generate combat sorties rather than serving only as a storage function.
The purpose of the transition becomes clearer when looking at current B-2 operations. In June 2025, seven B-2s departing from the United States took part in Operation Midnight Hammer against Iranian nuclear facilities, with multiple aerial refuellings and the use of 14 GBU-57 Massive Ordnance Penetrator bombs against heavily protected targets. That mission illustrates the role assigned to a U.S. strategic stealth bomber: departing from the continental United States, covering intercontinental distances, penetrating defended airspace and striking high-value targets with heavy or specialized weapons. The B-21 is intended to assume this mission with a newer platform designed from the outset to adapt to evolving radar systems, integrated air-defense networks and electronic warfare capabilities. Keeping the B-2 in service during the transition allows the United States to retain an immediately available penetrating-strike capability while the Raider enters service in larger numbers. The new Whiteman infrastructure supports that objective by reducing the risk that the technical and industrial transition creates an operational gap in one of the U.S. Air Force’s long-range strike capabilities.
