Is B-2 better than B-21?

The new B-21 Raider bears a family resemblance to the B-2 Spirit, but the two bombers will differ substantially in size, and likely their number of engines and payload. Critically, the B-21 will also be far more advanced in terms of low-observable technology—at least two generations beyond its elder stablemate.

What will replace the B-2?

The B-21 ‘Raider’, a stealth bomber being built by Northrop Grumman, is seen as the successor to the US’ B-1 and B-2 ‘Spirit’ warplanes. The construction of the sixth Raider (out of an expected 100 at least) began recently.

What replaced the B-52?

Last fall, the Air Force selected the F130 engine made by Rolls-Royce North America for the B-52 Commercial Engine Replacement Program, or CERP. Under the $2.6 billion contract, Rolls-Royce will equip the B-52 fleet with eight engines each by September 2038, replacing the bomber’s aging Pratt & Whitney-made engines.

What is the new LRS-B bomber?

The USAF plans for the new bomber to be multi-role with intelligence, surveillance, and reconnaissance (ISR) capabilities. As a bomber, the LRS-B will be under Air Force Global Strike Command, while ISR assets are managed by Air Combat Command ‘s 25th Air Force.

What is the cost of the LRS-B?

The LRS-B is intended to perform any long range mission, rather than one specialized mission, which drove up the cost of the B-2. The USAF expects it to cost $1 billion each with development costs factored in, and aims for a per-aircraft cost of $550 million, considered reasonable for a limited production run military aircraft.

How does the bomber compare to the B-2 bomber?

The bomber seems similar to the B-2, but more advanced using improved materials for superior low observability, similar to or smaller in size, and will operate alone or as part of a strike package with other airborne assets.
