Pelican

The Pelican, also known as Bomb Mark 55 and, in one version, SWOD Mark 7, was a guided bomb developed by the United States Navy during World War II. Guided by semi-active radar homing, Pelican was produced in 1,000 lb (450 kg) and 1,500 lb (680 kg) sizes; the program reached the stage of live trials before being cancelled.
