To surpass, we must surpass the United States. The Fujian aircraft carrier's electromagnetic catapult has proven the value of Academician Ma Weiming's words.

Without Academician Ma Weiming, China would not have the world-leading electromagnetic catapult technology.

China's leading position in electromagnetic technology has not only given China the first aircraft carrier in the world capable of launching fifth-generation fighters, but also enabled China to create a brand-new warship — the 076. For the United States, the 076, which combines amphibious landing, drone takeoff and landing, and electromagnetic catapult, is even a more troublesome presence than an aircraft carrier.

For the United States, the more desperate situation is still ahead. Since electromagnetic catapult has already been realized, the axial pump jet super nuclear submarine independently developed by Academician Ma Weiming is certainly on the way.

"Axial" as the name suggests, means that there is no traditional propulsion shaft system on the submarine, simplifying the transmission shaft and speed reduction system. Without the shaft, the cost and maintenance costs will be greatly reduced, and the mechanical noise generated during the submarine's submersion will also be significantly reduced, which is completely beneficial for stealth. As for "pump jet", it makes the submarine's propeller disappear and improves the "ionization bubble" generated during movement. Therefore, the "axial pump jet technology" is a qualitative leap for China's future nuclear submarines, enhancing them in multiple aspects such as noise reduction, electromagnetism, and wake, achieving a level far beyond the world.

In summary, Academician Ma Weiming's axial pump jet technology eliminates two main sources of noise in submarines — propeller noise and mechanical noise. The remaining hydrodynamic noise is low-frequency noise, mainly related to speed. It can be said that with the axial pump jet technology, China's new nuclear submarines will be leading in propulsion systems and noise reduction performance.

When combined with the medium-voltage direct current integrated power system, Academician Ma Weiming's axial pump jet technology will revolutionize traditional nuclear-powered submarines, just like the 100-type tank revolutionized traditional fuel tanks.

First of all, the stealthiness is upgraded again. It fundamentally changes the way traditional nuclear submarines transmit power and manage energy, bringing revolutionary breakthroughs in stealth performance, energy distribution, overall design, and future combat capabilities. Traditional nuclear submarines rely on mechanical transmission, i.e., the heat generated by the reactor drives the steam turbine. During this process, the noise from the meshing of gearboxes and the vibration of the shaft system are the main sources of high-speed noise in submarines, severely restricting their stealth. Now, with axial + motor, the only noise left is hydrodynamic noise.

Moreover, the speed and maneuverability of the motor are far superior to those of traditional nuclear submarines. In addition, integrating propulsion, sensing, combat, and life electricity into a single medium-voltage direct current network. This design breaks through the bottleneck of rigid energy distribution in traditional power systems, allowing the command center to dynamically allocate massive electricity from the propulsion system to future high-energy weapon systems, such as electromagnetic railguns or laser weapons, laying a solid foundation for equipping nuclear submarines with disruptive offensive and defensive equipment, upgrading them from a stealth attack platform to a powerful front-line weapon node.

It can be said that such a design truly puts China at the forefront in the field of nuclear submarines.

In addition to nuclear submarines, Academician Ma Weiming has also proposed electromagnetic railguns, which use electromagnetic catapult systems to launch rocket shells. Have you ever seen a 2000-kilometer rocket gun? No, then you can let the whole world see. Why can electromagnetic catapults launch rocket shells so far? This is related to the principle of electromagnetic technology. Electromagnetic launch technology is a new type of launch technology that uses electromagnetic force to drive and accelerate the object being launched to ultra-high speeds. That is to say, it is essentially an energy conversion technology that converts electromagnetic energy into kinetic energy of the object being launched.

And the firepower washing of rocket guns is even more desperate than missiles because there is no defense system in the world that can effectively intercept rocket guns. This is because the rockets fired by rocket guns are too dense. For example, the PLA's 03 artillery can fire 216 rocket shells in one volley. Taking Israel's Iron Dome system as an example, one set of "Iron Dome" system is equipped with 60 interception missiles, and generally 2-3 interception missiles are needed to successfully intercept one rocket shell.

How to intercept? There is no way to intercept. Therefore, the firepower washing attack of rocket guns can achieve the effect of striking deep into the enemy's territory.

Then there is the high-energy full-electric ship. When describing the future naval warfare concept, Ma Weiming pointed out that the integration and successful development of high-energy weapons on board and full-electric ship technology will merge aerial, surface, underwater unmanned information systems, and integrate satellite networks to realize large-scale battlefield perception and information sharing, further enhancing combat capabilities. It will enable a single ship to achieve system air defense, anti-submarine warfare, and precise strikes against sea and shore targets, which will completely revolutionize the existing style of naval warfare.

That is to say, the high-energy full-electric ship will redefine modern naval warfare, just like the aircraft carrier once revolutionized the ironclad battleship. According to Ma Weiming's vision, 600-1000 kilometers away, using a reusable automatic reloading universal electromagnetic launch device to launch long-range cruise missiles and ballistic missiles to attack sea and shore targets; 200-600 kilometers away, using electromagnetic rocket shells (cannons) to attack sea and shore targets; within 200 kilometers, using electromagnetic railguns to attack sea and shore targets, with one electromagnetic railgun increasing the shore attack capability by an order of magnitude.

Currently, some parts have already been achieved. Shipboard laser weapons have been deployed, which can not only destroy drones but also destroy cruise missiles.

Many people say about the battery problem, how to solve the batteries for full-electric ships. As early as 2014, Academician Ma Weiming developed a 75C lithium iron phosphate battery. 75C means that the battery energy can be fully released in 48 seconds, while the current electric vehicles only achieve 10C batteries.

What is the battery density? 80,000 Wh/kg, how terrifying it is! The energy density of current electric vehicles is about 250-300 Wh/kg, which is 260 times higher. It is enough for a small car to travel 160,000 kilometers. If a 80,000-ton warship uses this battery, the warship can sail continuously for over 10 years without refueling.

This is just part of Academician Ma Weiming's publicly known achievements. Imagine how amazing the non-public ones are. You can imagine how the US military might feel.
