Piper Cub plans

The history of the Piper "Cub" (Puppy) plane dates back to the beginning of the 1930s, when the Taylor brothers started production of the E-2 "Cud" sports plane at their Taylor Aircraft Corporation factory. It was a simple and cheap two-person upper arm that was quickly gaining popularity. By 1935, 157 aircraft had been sold, followed by 211 closed-cabin F-2s. In December 1937, after an outbreak of factories and factories moved from Bradford, Pennsylvania to Lock Haven, same state. The plane was improved, subsequent versions received the designation F-2 "Cub" and J-3 "Cub". Production grew steadily, three versions of the aircraft were offered, including a seaplane. In 1938, 737 aircraft were produced, in 1939 1806, in 1940 3016, and in 1941 the 10,000-year-old Piper "Cub" left the factory.

In 1941, the American army chose the J-3 plane for its needs, out of 12 types of light sport aircraft. After successful testing of the four sample units, the army placed an order for more. After delivering 140 copies, at the request of users complaining of poor rear visibility, of the next 948 aircraft ordered, 649 had already had the glazing enlarged on the rear and above. In 1942, another 981 aircraft were ordered and equipped with radio stations. A total of 5,548 Piper L-4 aircraft were produced for the army. Military planes received the nickname "Grasshopper" (grasshopper). After the war, the "Cub" Pipers were still produced, in the years 1931-1950, when the production ended, a total of 23,512 aircraft were produced. To this day, there are still several thousand of these aircraft in use around the world, which is the best proof of their durability. Piper L-4 planes participated in combat on all fronts of World War II, with the exception of the Eastern Front, and were used for such purposes as communication, observation and reconnaissance, correcting artillery fire, training. The planes did not have any weapons installed, but the crews used personal weapons and grenades, which were dropped manually, as at the beginning of World War I. M-6 Bazooka anti-tank missile launchers were mounted on the wing struts in a few "homemade" airplanes, they were fired electrically and reportedly were successful. During the whole war about 1000 planes were destroyed.
