Northrop Grumman B-21 Raider er et amerikansk tungt bombefly, der er under udvikling af Northrop Grumman for United States Air Force. Udviklingen af B-21 er en del af det amerikanske "Long Range Strike Bomber program" (LRS-B) og målet er udvikling af et avanceret, langtrækkende interkontinentalt bombefly med stealthegenskaber og med evne til at medføre større mængder konventionelle eller termonukleare våben.[1][2][3]
Pr. 2021 er det forventet, at B-21 vil kunne indsættes i tjeneste i 2026–27.[4] Det er planen, at B-21 skal komplementere de eksisterende Rockwell B-1 Lancer, Northrop Grumman B-2 Spirit,[5][6] og Boeing B-52 Stratofortress bombefly, der i dag indgår i den amerikanske flåde af bombefly, og på sigt erstatte disse.[7][8][9]

B-21 rendering 3.jpg
Shown is a Northrop Grumman B-21 Raider artist rendering graphic. The rendering highlights the future stealth bomber with Edwards Air Force Base, California, as the backdrop. Designed to perform long range conventional and nuclear missions and to operate in tomorrow’s high end threat environment, the B-21 will be a visible and flexible component of the nuclear triad. (U.S. Air Force graphic). This is the third USAF rendering of the B-21 Raider. Note changes in the windshield from previous official renderings.
