Western Electric AN/APS-2E Radar Plan Position Indicator

This Navy radar scope would have been used on long-range patrol aircraft, such as the Consolidated PB4Y, late in World War II and during the early Cold War. U.S. bombers during World War II used radar for short-range navigation—under 80 kilometers (50 miles)—and for bombing through clouds and at night (but less accurately than conventional bombsights). The system was only effective in locating cities and shorelines.
