The Raytheon MGM-157 EFOGM (Enhanced Fiber Optic Guided Missile), was a long range enhanced fibre optic guided missile developed for the U.S. Army during the 1980s and 1990s to test the use of fibre optics in missiles. The missile was launched vertically and manually controlled by an operator on the ground by use of a television camera mounted on the nose. The signals from the camera were carried via a thin wire that unspooled the further up the missile reached. The weapon was primarily designed for anti-tank use, or against low flying helicopters.
