PALMDALE, Calif. – On October 27, 2015, nearly 34 years to the day after Northrop Grumman was awarded the contract to develop the first stealth bomber, the U.S. Air Force awarded Northrop a contract for a new bomber: the B-21 Raider.

The Military & Aerospace Electronics take:

18 Oct. 2019 -- The B-21 Raider bomber takes its name from both the 21st century and the legendary 1942 raid by Gen. James “Jimmy” Doolittle’s force of B-25 Mitchell bombers against targets in and around Tokyo, Japan.

A tailless, batlike aircraft, the official rendering of the B-21 Raider released by the Air Force bears a superficial resemblance to the B-2 Spirit bomber. There are important distinctions, however.

The B-21 moves its engines closer to the wing root, where they occupy the juncture between wing and fuselage, whereas the B-2’s twin pairs of General Electric F118-GE-100 engines are distinctly apart from the fuselage on the wing. The Raider’s engine air intakes are angled and not serrated like those on the B-2 Spirit. The Raider also has overwing exhausts to mask the infrared signature of the four engines, unlike the B-2.
