You can track a submarine from space.
Most submarines are built with an emphasis on stealth.Advanced propeller designs, extensive sound-reducing insulation, and special machinery allow the submarine to be undetected but they have to eliminate the “submarine wake” and the sonar buoyos.In 1984, the U.S. Navy oceanographer aboard the “Challenger” space shuttle into space and successfully to detect other submarines of the ripple. Currently, the U.S. Navy anti-submarine satellite is in space and submarine sonar array, sea anti-submarine ships, air anti-submarine aircraft, together constitute the three-dimensional anti-submarine network.DARPA is working on anti submarine detection warfare.

In May 14,2011 , “Atlantis,” conducted last space shuttle flight, the crew, including Captain U.S. Navy submarine force, U.S. forces may take the opportunity to further test the potential of satellite hunting technology.
