The B-21 Raider was designed to slip through the world’s most advanced air defences and hold any target on Earth at risk. It was not designed to shoot down enemy fighters — but the U.S. Air Force is studying exactly that. In a report to Congress on the long-term structure of its fighter force, submitted in mid-October, the service listed “developing air-to-air capabilities on bombers” among the options it is weighing for the 2030s. It is one of the most consequential ideas American airpower has entertained in decades.
The report, briefed to reporters on October 20 and covered by Air & Space Forces Magazine, concludes the Air Force will need some 1,509 combat-coded aircraft by 2035 — hundreds more than it operates today. Roughly 40 percent of that fleet would be F-35As, alongside F-15EXs and the new F-47. But fighters alone may not close the gap. Alongside a possible new “capacity fighter” and greater reliance on Collaborative Combat Aircraft drones, the document puts bombers carrying air-to-air missiles on the table.
A Bomber in the Air-Superiority Conversation
For the B-21 specifically, the idea did not appear from nowhere. In October 2024, then-Chief of Staff Gen. David Allvin was asked whether the stealth bomber could take a larger role in the service’s air dominance plans, and he pointedly refused to rule it out: “We have not taken that off the table.” A year later, reporting indicated the Air Force was studying whether a large flying-wing stealth aircraft — potentially based on the B-21 — armed with dozens of air-to-air missiles could form part of its future air superiority force. The new fighter-structure report is the first time the concept has appeared in a formal document sent to Congress.
The Raider itself is meanwhile moving from unveiling to working test program. Built by Northrop Grumman, the flying-wing bomber was rolled out in December 2022 and first flew in November 2023. A second test aircraft has since joined the effort at Edwards Air Force Base, expanding the work into mission systems and weapons integration. The Air Force plans to buy at least 100, taking over from the B-1B Lancer and B-2 Spirit, flying alongside the endlessly modernised B-52.
Its day job remains penetrating strike: conventional and nuclear weapons delivered inside airspace that would kill older aircraft. But the same qualities — extreme range, broadband stealth, a large internal weapons bay and an open-systems design built to accept new equipment quickly — are precisely what an airborne missile carrier would want. The bomber would not need to become a fighter to matter in a fight for air superiority. It would need to be present, hard to find, and full of missiles.
Why the Pacific Makes Missile Numbers a Problem
The driving scenario is a war in the western Pacific, where geography works against American fighters. Distances from U.S. bases to a fight over Taiwan are enormous, tanker support is stretched thin, and China could concentrate large numbers of modern fighters from bases close to the battle. In that environment, the limiting factor may not be skill or stealth but simple arithmetic: how many missiles a formation can bring to the engagement before it must withdraw to refuel and rearm.
Fighters, even excellent ones, are limited missile trucks. A stealth fighter carries only a handful of air-to-air weapons internally, because carrying more under the wings would compromise the low observability that keeps it alive. A bomber suffers from no such constraint at anything like the same scale. Its internal bay — whose exact capacity remains classified — is built to haul heavy strike loads across intercontinental distances. Filled with air-to-air missiles instead, a single Raider could in principle carry the magazine of several fighters, and stay on station far longer than any of them.
That arithmetic is what planners mean by “missile capacity.” The fighter report is, at bottom, an admission that the future combat fleet may not generate enough shots. Bombers are the largest uncommitted reservoir of stealthy, long-legged carrying capacity the service owns — and tapping it requires weapons, software and a concept of operations, not a new aircraft.
How a Raider Would Fight Without Dogfighting
Nobody proposes sending a subsonic flying wing into a turning fight. The concept instead splits the kill chain across several aircraft: forward fighters, combat drones or other sensors find and track the target, while the bomber launches from far behind, never needing to close with the enemy at all. Detection, designation and launch — once done by one pilot in one cockpit — become jobs distributed across a formation. The bomber functions less like a fighter and more like an airborne arsenal ship that happens to be stealthy.
That division of labour plays to what modern air combat already rewards. Very-long-range missiles, cued by off-board sensors, increasingly decide engagements before either side sees the other, and the Air Force has even sought industry concepts for air-to-air weapons reaching out to around 1,000 nautical miles. A large, quiet launch platform extends the practical reach of such weapons: it can orbit inside or near contested airspace that a non-stealthy carrier could not survive in, and it can support the suppression of enemy air defences with the strike weapons that remain its primary trade.
The Raider could also serve as a command node for the drone wingmen the Air Force is building. Collaborative Combat Aircraft need controlling platforms that can survive in the same airspace, and a stealth bomber with powerful sensors and communications fits that description. In that version of the concept, the B-21 is not merely carrying missiles for other people’s targets — it is the formation’s quarterback.
A Long Way From a Decision
All of this remains study, not program. The report to Congress does not name the B-21 as the aircraft that would receive an air-to-air capability, sets no funding line, and confirms no operational configuration — a caution the Air Force itself has repeated. Turning the idea into hardware means qualifying air-to-air missiles for carriage and launch from the Raider’s bay, integrating the fire-control software, and answering hard questions about how a bomber fleet already central to nuclear deterrence should be shared with a second mission.
There are also honest doubts. A bomber is not manoeuvrable, and its survival in this role would rest entirely on stealth, electronic warfare and weapon range keeping it out of trouble. Critics can fairly ask whether diluting the penetrating-strike mission — the reason the B-21 exists — is wise, whatever the missile arithmetic says. Those questions are now asked inside the building, which is itself the news: wargames examining a 2035 fight with China have reportedly already included an air-to-air-capable Raider at the request of Pacific planners.
For now, the Raider’s future is being written at Edwards, where weapons-integration testing will decide what the bomber can actually carry and fire. If the studies harden into requirements, the aircraft unveiled as America’s next stealth bomber may end up doubling as its largest fighter. Either way, putting the option in a report to Congress shows how seriously the missile-capacity problem is being taken — and how much of the old line between “bomber” and “fighter” the next decade may erase.
