racks, usually in pairs or quartets, of infantry bazookas for ground attack (actually a form of top attack) against German armored units. The most famous of these L-4 ground attack planes was Rosie the Rocketer, piloted by Maj. Charles "Bazooka Charlie" Carpenter, whose six bazooka rocket launchers were credited with eliminating six enemy tanks and several armored cars during its wartime service, especially during the Battle of Arracourt. L-4s could also be operated from ships, using the Brodie landing system. After the war, many L-4s were sold as surplus, but a considerable number were retained in service. L-4s sold as surplus in the U.S. were redesignated as J-3s, but often retained their wartime glazing and paint. Postwar An icon of the era and of American general aviation, the J-3 Cub has long been loved by pilots and nonpilots alike, with thousands still in use. Piper sold 19,073 J-3s between 1938 and 1947, the majority of them L-4s and other military variants. After the war, thousands of Grasshoppers were civilian-registered under the designation J-3. Sixty-five pre-war Taylor and Piper Cubs were assembled from parts in Canada (by Cub Aircraft Corporation Ltd.). After the war, 130 J-3C-65 models were manufactured in Hamilton, Ontario. Sixteen L-4B models, (known as the Prospector), were later manufactured. The last J-3 model was assembled from parts at Leavens Bros. Toronto in 1952. J-3 Cubs were also assembled in Denmark and Argentina and by a licensee in Oklahoma. In the late 1940s, the J-3 was replaced by the Piper PA-11 Cub Special (1,500 produced), the first Piper Cub version to have a fully enclosed cowling for its powerplant and then the Piper PA-18 Super Cub, which Piper produced until 1981 when it sold the rights to WTA Inc. In all, Piper produced 2,650 Super Cubs. The Super Cub had a 150 hp (110 kW) engine which increased its top speed to 130 mph (210 km/h). Its range was . Korean War service The L-4 was used extensively by both U.S. and South Korean Air Forces in the early 1950s. During the Korean War, the L-4 was in service in many of the same roles it had performed during World War II, such as artillery spotting, forward air control and reconnaissance. Some L-4s were fitted with a high-back canopy to carry a single stretcher for medical evacuation of wounded soldiers. Modern production Modernized and up-engined versions are produced by
