The Douglas A-4 Skyhawk was developed in the 1950s and was one of the most famous light attack aircraft in aviation history. Its small and compact size made it extremely maneuverable and ideal for use on aircraft carriers. It featured a low-slung triangular wing, two small air intakes on the sides of the fuselage, and the use of a single Pratt & Whitney J52 turbojet engine. It was armed with two 20-mm. guns, and with hardpoints under the wings and under the fuselage, the Skyhawk could support a wide range of air-to-air, air-to-surface missiles, rockets and bombs. Due to its operational capabilities, the A-4 was a good commercial success and was adopted by several air forces around the world. In addition to the United States, it was used, in particular, by Australia, The McDonnell-Douglas A-4 Skyhawk is an American attack aircraft, the prototype of which first took to the air in 1954.
