The latest U.S. long-range strategic bomber B-21 "Raider" will be unveiled on the 2nd at the U.S. arms manufacturer Northrop Grumman's factory in Palmdale, California.

The cost of loading nuclear and traditional weapons is 21.7 billion each

[Compilation of Zhang Peiyuan/Comprehensive Report] The U.S. Air Force is expected to announce at 7:30 p.m. Eastern time on the 2nd (8:30 a.m. Taiwan time on the 3rd) the first new bomber in more than 30 years, which can carry nuclear and traditional weapons and has unmanned potential. The high-tech stealthy long-range strategic bomber B-21 "Raider" (Raider).

The cost of each B-21 that will fly for the first time next year is nearly 700 million U.S. dollars (approximately 21.7 billion Taiwan dollars). The U.S. Air Force will purchase at least 100 of them to gradually replace the B-1 and B-2 bombers that first flew during the Cold War.

Gradually replace B1 and B2 and become the backbone of the US Air Force

U.S. Air Force spokesman Stephen Nick said that the B-21 will become the backbone of the U.S. Air Force's future bombing force. danger.

Northrop Grumman, the U.S. arms manufacturer that manufactures the B-21, said it has six B-21s in various stages of assembly and testing at its plant in Palmdale, California. .

The B-21 unveiling ceremony was held at this factory.

One of the achievements of the Pentagon's "Nuclear Triangle"

The B-21 is part of the Pentagon's pursuit of a modernized "nuclear triangle" consisting of land-based ballistic missiles, submarine-launched intercontinental missiles and air-launched missiles.

In 2015, then-U.S. Air Force Secretary James James, who announced the B-21 procurement contract, said that the U.S. military needed the B-21 to deal with more complex threats such as those from China and Russia.

According to a report on China's military power released by the Pentagon this week, the People's Liberation Army will have 1,500 nuclear weapons by 2035.

With unmanned driving function "prepared for any danger"

Many of the B-21's features are still under wraps, but the aircraft should significantly increase the capabilities of the U.S. Air Force fleet, one of which is the potential to be unmanned.

Stefanik called the B-21's unmanned capability "ready to go," and no decision has yet been made on whether the aircraft will be unmanned.

In addition, the B-21 has an "open architecture" feature, which means that the aircraft can be upgraded more easily and faster.

Like F-22 and F-35, B-21 also adopts stealth technology, and it is "next generation stealth" technology, built with new manufacturing technology and materials.

Northrop Grumman said this would give the B-21 an "anti-access/area denial" capability to defeat adversaries, but did not elaborate.

One of the PLA's modernization goals is to build an "anti-access/area denial" capability against the United States.

Open evolutionary design to integrate improved software

Nielsen, a researcher at the Brookings Institution, a think tank in Washington, pointed out that the B-21 is designed to be able to evolve; the "open architecture" allows for the integration of improved software (including automatic functions) in the future, so that the aircraft will not become obsolete too quickly; For several generations of bombers, the B-21 is more refined and modern. Not only is it dual-capable, it can launch nuclear and traditional armed warhead missiles, as well as long-range and short-range missiles.
