What is a piper J-3?

Answer

The J-3 Cub aircraft were born from Piper Aircraft engineer Walter Jamouneau's changes to the existing J-2 design. Even before J-3 Cub aircraft went into production, war had already broken out in Asia, while armed conflict in Europe seemed imminent; thus, on 27 Dec 1938, President of the United States Franklin Roosevelt announced a Civilian Pilot Training Program ("CPTP") that would train civilians piloting skills in preparation of war, and J-3 Cub aircraft became the primary trainer aircraft of the program.

Between 1938 and 1944, over 75 percent of 435,165 pilots who graduated from the program were trained in J-3 Cub aircraft. As the United States entered the war, civilian J-3 Cub aircraft patrolled both coasts of the United States, spotting for enemy submarines. Very soon, the United States military placed their order for J-3 Cub aircraft.

The military variant, with enlarged Plexiglas windows, was designated L-4 Grasshopper by the US Army and O-59/NE-1 Grasshopper by the United States Navy and Marine Corps. Grasshopper aircraft were used extensively for reconnaissance, transport of supplies, and evacuation of wounded. Some US Army Grasshopper aircraft were equipped with infantry rocket launchers to support ground troops, and they fulfilled their ground support missions effectively.

Production of J-3 Cub and L-4/O-59/NE-1 Grasshopper aircraft continued until 1947; a total of 19,073 were built during the design's production life, most being the L-4 variant. At the height of demand, one aircraft was built every 20 minutes. A few remained in service with the US Army through the Korean War, though most were scrapped or sold to the civilian market as surplus.
