Chinese scientists at Harbin Engineering University are on the brink of revolutionizing submarine propulsion with a cutting-edge laser-induced plasma detonation wave system. This breakthrough could pave the way for a new class of high-speed, silent submarines, a development that has captured international attention and raised concerns about naval warfare capabilities.
According to recent reports by the South China Morning Post, Engineers at Harbin Engineering University have been refining a novel concept of propelling submarines underwater using high-energy lasers to create plasma. This plasma, generated by lasers directed through ultra-thin optical fibers coating the submarine’s exterior, produces a detonation wave that propels the vessel forward. The system promises speeds faster than sound, comparable to jet engines, heralding a new era in submarine technology.
How Laser Propulsion Works
The newly developed system, known as “underwater fiber laser-induced plasma detonation wave propulsion,” focuses laser energy through optical fibers to generate substantial thrust with minimal energy input. This innovative approach yields up to 70,000 newtons of thrust using only 2 megawatts of laser power, equivalent to the force exerted by a commercial jet engine.

Previous attempts at laser propulsion faced obstacles, particularly in directing the generated force efficiently. Harbin Engineering University researchers, led by Dr. Ge Yang, have successfully addressed these challenges by integrating specialized devices resembling gun barrels at the ends of optical fibers. These devices optimize energy harnessing and minimize internal friction, enhancing propulsion efficiency.
The adoption of laser propulsion represents a significant departure from conventional propellant methods. By utilizing lasers to induce plasma and create supercavitation, submarines can potentially reach supersonic speeds underwater. Moreover, the absence of moving parts in this propulsion system ensures silent operation, bolstering stealth capabilities.
China’s strides in laser propulsion technology underscore its commitment to advancing underwater military capabilities. The potential deployment of silent, high-speed submarines equipped with this technology could reshape naval strategies and intensify concerns over submarine arms races.

The implications extend beyond submarines; this technology could also power underwater missiles and torpedoes, amplifying China’s strategic edge in maritime operations. However, further research is necessary to optimize system components for real-world deployment, addressing challenges such as heat dissipation and durability in high-salinity environments.
The rapid progress of Harbin Engineering University’s research has drawn scrutiny from international observers, particularly the United States, reflecting heightened competition in maritime technologies. This development underscores the intersection of scientific innovation, military strategy, and geopolitical dynamics.
