Northrop Grumman B-21 Raider Stealth Bomber to Replace B-2s, B-1s

The U.S. Air Force plans to retire its fleet of Rockwell B-1B and Northrop Grumman B-2 stealth bombers in a “Bomber Vector” roadmap that will be laid out in the coming weeks.

As Northrop’s next-generation B-21 “Raider” comes online in the mid-2020s, the Air Force wants to phase out the nuclear-capable B-2 and conventional B-1, according to two sources with knowledge of the budget discussions.

The Northrop Grumman B-21 Raider is a heavy bomber under development by Northrop Grumman. As part of the Long Range Strike Bomber program (LRS-B)

It is to be a very long-range, stealth strategic bomber for the United States Air Force capable of delivering conventional or thermonuclear weapons.

The bomber is expected to enter combat service by 2025.

It is to complement existing Rockwell B-1 Lancer, Northrop Grumman B-2 Spirit and Boeing B-52 Stratofortress bomber fleets in U.S. service and eventually replace these bombers.

The Air Force initial plans are to acquire a minimum of 80 to 100 LRS-B aircraft at a cost of $550 million per unit (2010) and envisions some 175 to 200 to be in service eventually.

The Air Force is planning to acquire a new long-range fighter, known as “Penetrating Counter-Air” (PCA), that would accompany the B-21 Raider deep into enemy territory.


The new fighter, of which few details are known, would help the bomber survive enemy air defenses.

Final assembly of the B-21 is expected to take place at the United States Air Force Plant 42 in Palmdale, California, at the same facility used during the 1980s and 1990s for Northrop B-2 production.

Northrop Grumman was awarded a $35.8 million contract modification for a large coatings facility set to be completed in 2019.

Journalists touring Plant 42 reported that “while Northrop would not specify that they planned to produce the B-21 at that location, officials were all but winking and nodding at the subject.”
