How The B-21 Raider Stacks Up Against The B-2 Spirit, B-52, & B-1 Lancer

The next-generation Northrop Grumman B-21 Raider is now test flying with the United States Air Force and is expected to enter service in 2027. The first bomber the B-21 is expected to replace is the B-1B, before eventually replacing the B-2 Spirit and operating alongside the B-52 into the 2050s. It should be noted that while the B-21 will replace the B-2 rather directly, it is replacing the B-1B in a very different sense.
