China is using Lasers
Scientists at a Chinese research institute say they developed an airborne laser that might eventually detect hostile subs even at great depths.
The idea is to use laser beams of various colors that can detect disturbances in the water caused by a moving submarine.
The new blue-green lasers devised by the Shanghai team reportedly have been tested at lower altitudes, from aircraft flying between 1,500 and 3,000 feet.
But aircraft-mounted lasers tend to be low-powered, so it remains to be seen whether the new lasers will be successful in locating deep-diving subs.
