The US Air Force confirmed that the B-21 will be flown by two pilots, launching a transition program for Weapons Systems Officers and Combat Systems Officers who will be chosen to attend pilot training.
The US Air Force officially confirmed on July 9, 2026 that the B-21 Raider will operate with a crew of two pilots. The confirmation ended months of speculation over whether the new stealth bomber would be flown by a pilot and a Weapons Systems Officer (WSO).
However, WSOs and combat systems officers (CSOs) will continue to play a role in the B-21 community. In fact, the service is launching a transition program that will allow selected WSOs and CSOs to attend undergraduate pilot training before receiving follow-on assignments to the Raider.
The announcement resolved an internal debate that became public in late 2025 after reports revealed that former Air Force Global Strike Command (AFGSC) commander Gen. Thomas Bussiere had recommended replacing one of the pilots with a WSO. The service then conducted an evaluation to determine the best composition for the crew.
Two pilots remain the preferred solution
in your Press releaseThe Department of the Air Force stated that the decision followed a thorough review of the Raider’s capabilities and requirements.
“After careful analysis of the B-21’s advanced capabilities, Air Force leadership determined that a two-pilot configuration optimally supports the aircraft’s mission profile,” the statement said. “To maximize the lethality and survivability of the Raider, it is imperative to retain the deep tactical and combat expertise that currently resides in the WSO and CSO communities.”
In this way, the B-21 will have two qualified pilots in the cockpit and, at the same time, will also retain the competencies of the WSO and CSO. The service further explained that eligible officers will receive further guidance through their command channels, although a timeline for the transition program has not been revealed.
Reverse the proposed pilot-OSM concept
The announcement effectively nullifies a proposal that emerged last year, first reported by aviation week. The report mentions a memo from then-head of the Air Force Global Strike Command (AFGSC), General Thomas Bussiere.
“Unlocking the Raider’s full potential requires a complex combination of skills: air prowess, weapons handling, electromagnetic spectrum operations, sensor management, real-time battle management, and agile combat replanning. For this reason, the B-21 will be crewed by a pilot and a weapons systems officer,” Bussiere wrote.
The report was published in August, although the first public reports did not arrive until months later, in November. At the time, this crew complement was still a recommendation and not yet a final decision toward a new Air Force policy.
However, as we reported back then, the service also previously announced in 2020 plans to allow current WSOs from current B-52 Stratofortress and B-1B Lancer units retrain as pilots before the arrival of the B-21. It is unclear whether this developed beyond the proposal stage and whether any OSM underwent such role conversion training.
Long duration missions remain a key factor
Although the Air Force has not detailed all of the factors behind the decision, the nature of the B-21’s expected missions makes the reasoning relatively simple. Like the B-2 Spirit it will eventually replace, the Raider is designed for round-trip strike missions from its US bases lasting more than 24 hours.
For example, during Operation Midnight Hammer, B-2 Spirit bombers flew approximately 37-hour round-trip missions from Whiteman Air Force Base, Missouri, to attack Iranian nuclear facilities before returning directly to the United States. Similar durations for missions were also reported during Operation Epic Fury.
Such sorties require pilots to alter their flight duties, allowing one crew member to rest while the other remains at the controls. The B-2 already incorporates facilities – such as a bathroom and kitchenette – to support the crew during these extended flights, and AFGSC has previously indicated that the B-21 will provide similar accommodations.
Additionally, maintaining two fully qualified pilots also provides additional redundancy during demanding missions and reduces workload during critical phases such as mid-air refueling and attacks in highly contested airspace.
Looking forward
The Air Force continues to prepare for the operational debut of the Raider in the near future. Currently, two representative production aircraft are undergoing flight testing at Edwards Air Force Base, California.
The first operational B-21 unit is expected to be standing at Ellsworth Air Force Base, South Dakota, in 2027. Secretary of the Air Force Troy Meink confirmed the unit will receive one of the two aircraft currently at Edwards. according Air and Space Forces Magazine.
“The test plane will go there,” Meink said. “At some point we are going to convert the test aircraft into an operational aircraft. They will go there and start to actually do the things that need to be done to prepare the base to get the operational aircraft there in the long term.”
The service is working to accelerate the deployment of its new stealth bomber. Work is already underway at Ellsworth to build the necessary facilities and prepare to receive the new aircraft.
“We really pushed to accelerate a lot of this activity,” Meink said. “This will put those planes in the hands of actual units, so they can start figuring out how they’re going to operate them. It’s pretty exciting.”
Personnel will soon begin familiarizing themselves with the bomber to be ready for its entry into service, establishing standard operating procedures (SOPs) and policies. Once the crew composition is formally established, the service can also begin building the required pilot pipeline.
