The B21 Raider is a technological marvel that ushered in a new era of strategic bombers in the rapidly developing field of military aviation. This article digs into the heart of this revolutionary plane, exploring its layout, capabilities, and the technological breakthroughs that give it its power.

History of  b21 raider

For the United States Air Force (USAF), Northrop Grumman is developing the B-21 Raider, a strategic bomber. The United States Air Force intends for this aircraft to fulfill the role of a long-range, stealthy intercontinental strategic bomber capable of delivering both conventional and thermonuclear missiles as part of the LRS-B program. By 2040, the B-21 is expected to replace the Rockwell B-1 Lancer and Northrop Grumman B-2 Spirit, with the Boeing B-52 Stratofortress as a possible subsequent replacement.

The Air Force began planning for the B-21 in 2011 and received the major development contract in 2015.On November 10, 2023, the B-21 made its first voyage, and it is projected to enter service by the year 2027.

The B-21 program is classified as a special access program because of the secrecy surrounding many aspects of it. Although some information about various aspects of the program has been made public since 2015, the Congressional Research Service noted in 2021 that the B-21’s technical details and specifications, including speed, enabling systems, “size, required stealth, structure, number and type of engines, projected weapons, and onboard sensors, remain classified.” The first images of the aircraft were revealed on 2, 2022, taken during a rollout event at Northrop Grumman’s production facilities in Palmdale, California.

Production and assembly

In November 2022, Northrop will unveil their first B-21 at its Palmdale, California plant.

In February 2016, the director of the Air Force Global Strike Command said he thought the service will place an initial order for 100 B-21s and develop up to a full fleet of 175 to 200. In 2017, two USAF studies showed that Air Force might boost its first acquisition from 80-to-100 to 145 aircraft.

The B-21 is put together at the same facility that Northrop Grumman used to assemble B-2 bombers in the 1980s and 1990s—Air Force Plant 42, located near Palmdale, California.

A contract modification worth $35.8 million was given to Northrop Grumman in January 2017 for the construction of a sizable coatings facility at Plant 42. Construction is expected to be finished by the end of 2019. Although B-21 wasn’t mentioned in the deal announcement, the facility is most likely intended for stealth coating on the aircraft. The first plane was reportedly being built by the summer of 2019. Multiple news sources announced in early 2021 that work on the second B-21 had begun, close to the first unit’s scheduled completion.

The first two B-21s are currently being built at Plant 42, according to testimony given by Darlene Costello, acting Assistant Secretary of the Air Force Acquisition, Technology, and Logistics, at a congressional hearing in June 2021.

Six B-21s were being built by the end of February 2022. The next month, the first B-21 was relocated to a calibration facility. Over 400 suppliers from at least 40 states and 8,000 Northrop Grumman personnel worked together on the initiative.

Officials with the program reported in September 2023 that fueling and engine tests were progressing in preparation for the first flight by the end of the year. On November 10, 2023, at Air Force Plant 42 in Palmdale, California, the B-21 took to the skies for the first time in its history.

Program costs

The United States Air Force (USAF) stated in July 2016 that it will not divulge Northrop’s B-21 contract’s projected cost because doing so would reveal too much information about the classified project. Over the protests of a bipartisan group of legislators led by the committee’s chairman, Senator John McCain, the Senate Armed Services Committee likewise agreed to not publicly divulge the cost of the program, confining the information to legislative defense committees. According to McCain’s proposed amendments to the National Defense Authorization Act for Fiscal Year 2017, the B-21 program’s funding would have been cut by $302 million “due to a lower than expected contract award value,” and “strict…program baseline and cost control thresholds” as well as “quarterly program performance reports” and “disclosure of the engineering and manufacturing development total contract award value” would have been mandated. The versions of the 2017 NDAA as initially enacted by the House and Senate would have compelled public disclosure of the overall cost of the B-21, but this language was eliminated in the final conference report version.

A B-21 plane was predicted to set you back $700 million in December of 2022. At the time, Air Force officials projected that they would spend at least $203 billion over 30 years to develop, purchase, and operate a fleet of 100 B-21s.

Maintenance, sustainment, and operation

The B-21 will be tested and evaluated at Edwards Air Force Base in California, while Tinker Air Force Base in Oklahoma will be responsible for its maintenance and sustainment. Dyess Air Force Base in Texas, Ellsworth Air Force Base in South Dakota, and Whiteman Air Force Base in Missouri are among of the projected B-21 sites of operation. Ellsworth was chosen in March 2019 as the location to house both the first operational B-21 unit and the first training unit.

Planned role in fleet

By 2040, the B-21 will have replaced the 45 B-1 strategic bombers from the 1980s and the 20 B-2 bombers from the 1990s in the United States Air Force. The B-52, which is expected to stay in service for decades to come, could be replaced by the B-21 in the future.

Potential related projects

Since it wouldn’t be cost-effective to manufacture such a huge unmanned aircraft, Air Force Secretary Frank Kendall nixed the notion of a bomber drone in March 2022.

As part of its Next Generation Air Dominance program, the United States Air Force (USAF) is looking to buy a new long-range fighter known as the F-X or “Penetrating Counter-Air” to accompany the B-21 deep into enemy territory and protect it from air defenses and intercepting aircraft.

Possible Australian interest

In December 2022, an Australian Strategic Policy Institute report supported the acquisition of a number of B-21 Raiders to enable Australia to have a higher long-range strike capacity.

When compared to the greatest range of the RAAF’s F-35 fighter jets, which is 930 miles (1,500 km), the B-21 can fly 2,500 miles (4,000 km) without refueling while carrying more weapons. A single B-21 can do the work of multiple F-35As. The B-21 has access to more troops, fuel, and ammunition, and it can launch attacks from safe air bases in southern Australia.

The United States reportedly discussed letting Australia buy the B-21 during bilateral discussions in August 2022. I don’t think that there’s any fundamental constraint on the areas in which we may work,” Air Force Secretary Frank Kendall said when asked if the United States would consider inviting Australia to participate in building the B-21 bomber. We’d be open to discussing long-range strike needs with Australia if they ever arose.However, the B-21 was not deemed an appropriate choice for acquisition in the Defence Strategic Review published by the Australian government on 24 April 2023. In order to be able to use the AGM-158C LRASM and the Joint Strike Missile, Australia will instead upgrade its F-35As and F/A-18Fs to the most recent Block 4 and Block III variants, respectively.

Is the B-21 Raider better than the B-2?

Although the new B-21 Raider is related to the B-2 Spirit, these two bombers will be very different in terms of size, powerplant complement, and payload. The B-21’s low-observable technology will be at least two generations ahead of that of its older stablemate, which is a crucial advantage.

Does the B-21 Raider need a pilot?

Both piloted and unpiloted versions of the plane are in the works.

How much is the B-21 Raider worth?

Although the B-21 Raider’s development and price have been shrouded in secret, Reuters estimates that each plane will cost around $750 million.

Why is it called the B-21 Raider?

The B-21 was officially given the name “Raider” in September 2016 by Air Force officials as a tribute to the Doolittle Raiders. At the Air Force Association convention, retired Lt. Col. Richard E. Cole presided over the naming ceremony as the only surviving member of the Doolittle Raiders.

How far can a B-21 Raider fly?

When compared to the greatest range of the RAAF’s F-35 fighter jets, which is 930 miles (1,500 km), the B-21 can fly 2,500 miles (4,000 km) without refueling while carrying more weapons.
