B-21 Raider Capabilities

The B-21 Raider is a next-generation long-range penetrating stealth bomber developed by Northrop Grumman for the U.S. Air Force. It is designed to replace the B-1B Lancer and B-2 Spirit and eventually operate alongside the modernized B-52J. The bomber uses a flying-wing design, low-observable shaping, signature-management technologies, and advanced mission systems to penetrate heavily defended airspace. These features are intended to reduce detection by modern radar networks and improve survivability against long-range surface-to-air missiles, fighters, and integrated air-defense systems.
