Shown here is the second U.S. Navy Lockheed WV-1 Warning Star (BuNo 124438) of airborne early warning squadron VW-1 Typhoon Trackers at Naval Air Station Barbers Point, Oahu, Hawaii (USA), in December 1952. The WV-1 was delivered for training purposes before the delivery of the production WV-2. Note the smaller radome of the APS-20 radar below the fuselage compared to the VW-2 (after 1962 EC-121K).
