US Expert:Four new weapons may define the defense posture of the new US government

By yqqlm yqqlm

Introduction

On November 13, Loren Thompson of the Lexington Institute in the United States published an article to predict the defense situation of the new US government by analyzing four types of weapons.

“Columbia” class strategic nuclear submarine

The key feature of the US deterrence strategy is the United States Not only can it protect the country from nuclear attacks by its opponents, but it also has the ability to launch repressive and destructive retaliation against any aggressor. This deterrence strategy requires the US military to have a force that can survive any attack and at the same time respond in a manner commensurate with the provocation. Ballistic missile nuclear submarine is the core of deterrence strategy. Currently, about two-thirds of the warheads in the US nuclear arsenal are carried by 14″Ohio” class submarines. But these submarines will gradually begin to retire in the near future. The”Columbia” class nuclear submarine was proposed by the Obama administration to replace the”Ohio” class submarine and will become the largest submarine ever built by the United States. General Dynamics, the main contractor, plans to deliver to the Navy in 2027 and conduct its first deterrent patrol in 2031.

In order to comply with the arms control agreement, the”Columbia” class nuclear submarine has only 16 pipelines for launching long-range ballistic missiles. But each D5 missile produced by Lockheed Martin will carry multiple independent target warheads that can destroy any enemy assets.

U.S. Navy will eventually have 12″Columbia” class nuclear submarines, the deterrent effect is equivalent to the deterrence effect of 14″Ohio” class submarines, and the core system of the”Columbia” class nuclear submarine propulsion device can use 40 year. Therefore, the possibility of the new government delaying or curtailing the Colombian project is zero.

B-21″raid” long-range bomber

Same as sea-based deterrent , The space-based deterrent also needs modernization. All heavy bombers in the current Air Force fleet will gradually lose their ability to penetrate the defensive airspace in the next few years, and will not be able to use air-dropped cruise missiles to destroy some targets from outside the airspace. The main advantage of a bomber in deterrence is that if circumstances permit, the bomber can be recalled or redirected after launch.

The B-21 bomber was also conceived by the Obama administration and plans to replace the B-1 and B-2 bombers as a penetrating long-range attack aircraft. The B-21 is not only a strategic deterrent, but also a conventional bomber capable of carrying a variety of intelligent ammunition. The combination of stealth and flexible electronic warfare systems makes it almost impossible to track or intercept. The B-21 is also part of a series of systems developed by the US Air Force for future global strike missions. As the core, it will affect the effectiveness of future joint forces in all-out wars. Therefore, in this regard, the possibility of the new government reducing the plan is zero, and even more likely to increase the related purchase plan.

On the other hand, Northrop Grumman, the main contractor, is assembling the fighter in California. It uses Pratt & Whitney engines. It uses digital engineering, agile software development, and rapid prototyping. Numerous cutting-edge production technologies. The new technology will greatly reduce the construction and maintenance costs of each bomber. Therefore, the fighter jet will easily become the main force of the new government’s emphasis on military investment strategy innovation.

Navy CH-53K heavy helicopter

Previously, the US Marine Corps introduced The MV-22″Osprey” tilt-rotor aircraft and F-35B fighter aircraft changed its aviation department. These fighters provide ground forces with unprecedented agility. Combined with maritime power, these fighters allow the Marine Corps to respond quickly to crises almost anywhere. However, in this combat scenario, a cargo helicopter is missing to transport the latest tactical vehicles from offshore amphibious ships to a theater 100 miles away. The CH-53K heavy helicopter, which entered service during the Obama administration, met this demand. Not only can it carry more weight than any other rotorcraft in history, but it also has lower maintenance costs and is also better able to defend against hostile fire.

As the Marine Corps takes action to curb the actions of rival countries in the Western Pacific, the value of CH-53K will continue to grow. In addition to expanding the size of its amphibious fleet, the Marine Corps also plans to move troops between China’s coastal islands in a way that China cannot easily predict or counterattack. This requires hoisting anti-ship weapons, tactical vehicles and other materials in a short period of time, some of which are too heavy for existing rotorcraft to be transported.

The Marine Corps plans to purchase 200 CH-53Ks from Lockheed Martin with a 130-mile unrefueled combat radius and excellent performance under”high temperature” conditions. Change the rules of the game within the scope. The contractor hopes that the new government will provide the Marine Corps with production aircraft for the first year, thereby further enhancing the flexibility of this world-class amphibious force.

Unmanned surface craft and underwater battleship

Early this month, for the US Navy The developed test surface ship completed the 5,400-mile mission from the Gulf of Mexico to California, passing through the Panama Canal, and the entire mission execution process was completely autonomous without human intervention. The test boat is part of the Navy’s continued investment in unmanned surface and underwater ships.

U.S. Navy leaders believe that increasing the use of unmanned systems is the only affordable way for them to complete all assigned tasks worldwide. Although manned warships will still be the core asset of the US Navy’s operations, the Navy also needs unmanned warships as a low-cost method to complete more dangerous missions.

Unmanned battleship construction and operation and maintenance costs are only a small part of conventional ships, but at the same time greatly enhance the capabilities of the entire fleet. This concept will attract the security team of the new government, dedicated to accelerating military innovation. As federal borrowing has reached a record level, the new government will also have a strong incentive to seek alternatives to unmanned driving to replace traditional combat concepts.
