On December 2, 2022, U.S. time, a scene that attracted the attention of the world was staged, and the U.S. military's new generation of strategic bomber B-21 "Raider" was officially unveiled. Manufacturer Northrop Grumman is full of praise for this **, declaring the B-21 to be the world's first sixth-generation aircraft. In terms of appearance, the sci-fi shape of the B-21 is slightly smaller than the B-2, the air intake is flatter, and it may not be as good as the B-2 in terms of range and bomb load, but it has more advantages in stealth and **. The level of avionics and battlefield situational awareness gives it a late-mover advantage.
The United States plans to purchase at least 100 B-21s at a cost of about $500 million each, and in the next few decades, the B-21s will gradually replace the B-52H, B-1B and B-2 in service and become the main force of the U.S. strategic bombing force. However, with the advancement of technology and the development of the times, the F-22 fighter jet built for tens of billions of dollars was forced to stop production after the production of 187 units, so there is also uncertainty in the procurement of 100 B-21s by the US military.
Despite this, the appearance of the B-21 should not be underestimated, and the meaning behind it is even more far-reaching - the new triad of nuclear strikes by the US military has taken shape.
At present, the US military's three-in-one nuclear strike capability includes land-based Minuteman-3 intercontinental missiles, 14 sea-based "Ohio"-class strategic nuclear submarines, and air-based B-52H, B-1B, and B-2 strategic bombers. However, most of these missiles and platforms are still Cold War-era products, and their performance has fallen short compared to the latest ** of other major powers.
The United States is aware of this and in recent years has begun to vigorously develop a new triad of nuclear strike capabilities. The unveiling of the B-21 marks the renewal of the space-based sector, and the land-based and sea-based are also in full swing in the renewal program.
To replace the Minuteman 3 ICBM, the US military proposed a new generation of ICBMs "Sentinel". It is reported that the "Sentinel" will enter service in 2029, using a new engine, flight control system and booster, which is lighter than the Minuteman-3 and has a TNT yield of 500,000 tons. The entire plan will cost $100 billion.
The replacement for the Ohio-class strategic nuclear submarine is the Columbia-class, which uses a number of new technologies, including a silencing coating, a waterjet propulsion and a binary acoustic stealth streamlined enclosure. Although the cost of a single submarine is close to $10 billion, the United States plans to invest $110 billion to build 12 "Columbia"-class nuclear submarines. Nuclear submarines of this class will be equipped with updated Trident improved submarine-launched missiles with a nuclear strike yield of more than 1 per ship500 million tons. It is expected that the "Columbia" class will be launched in 2028 and enter service in 2031.
Therefore, in the next ten years, the United States will comprehensively update its triad of nuclear strike capabilities, which will be undertaken by the B-21, Sentinel, and Columbia classes, respectively. These new ** will undoubtedly be ahead of the times and demonstrate the strong strength of the US military.
The appearance of the new US military not only ushered in a new era of nuclear strikes, but also demonstrated the ambition of the US military on a global scale. This series of strategic updates will undoubtedly have a far-reaching impact on the international military pattern and bring about a new military balance in the world. The B-21 "Raider", a new generation of intercontinental missile "Sentinel" and the huge "Columbia"-class nuclear submarine, will work together to build a powerful US nuclear deterrence system and contribute to the maintenance of international peace and security.
Recently, the appearance of the US military's new generation of strategic ** has attracted widespread attention, among which the official appearance of the B-21 "Raider" strategic bomber has attracted much attention. This bomber, which is known as the world's first sixth-generation aircraft, shows a sci-fi shape in appearance, and is more compact and compact than its predecessor, the B-2. The article mentions that the B-21 may be slightly inferior to the B-2 in range and bomb load, but it has more advantages in stealth and **, which provides more possibilities for future military operations.
However, with the development of the times and the upgrading of technology, the F-22 fighter jet built for tens of billions of dollars was also forced to stop production after 187 units were produced, which also reminds us that the purchase of 100 B-21s may face certain uncertainties. The speed of development of military technology is so fast that a ** may be ahead of the curve at the beginning of service, but the future trend is difficult**, which is also a norm in the arms race.
In the article, the author mentions plans for the renewal of the US military's triad of nuclear strike capabilities, including a new generation of intercontinental missiles "Sentinel" to replace the "Minuteman-3" and the upcoming construction of "Columbia" class nuclear submarines. This series of updates demonstrates the strong determination of the United States to maintain *** and nuclear deterrence. However, the high cost of construction and the complexity of technology research and development will also be a challenge for this plan, especially in the current uncertain global economic situation.
For the United States, updating its nuclear strike capability is undoubtedly a necessary measure to strengthen its national defense capabilities and maintain its national defense capabilities. However, it has also raised international concerns about the intensification of the arms race. An arms race may lead to an escalation of global military tensions, exacerbate international contradictions, and pose a threat to world peace and security. Therefore, it is necessary for the international community to work together to maintain global peace through dialogue and cooperation.
Overall, the appearance of the US military's new-generation strategy is a bright spot in today's international military landscape. However, while pursuing military strength, countries should also attach importance to resolving differences through diplomatic means to jointly promote global peace and security. Only through cooperation and communication can we truly achieve a lasting and stable international order.
