History
The Do 27 was developed from the Do 25, an aircraft originally designed to a Spanish military requirement for a light utility aircraft.
The Do 27 seated four to six and the original prototype first flew in Spain on 27 June 1955.[1] Most production aircraft were built in Germany, the first taking flight on 17 October 1956. The remainder (50) were manufactured in Spain by Construcciones Aeronáuticas SA as the CASA-127.
The German Luftwaffe and German Army ordered a total of 428 of the Do 27A and Do 27B (with dual controls).[2]
A later version with the same basic specifications but equipped with wider track landing gear was known as the Do 27Q-5. The aircraft was offered as a twin-float seaplane, the Do 27S-1, and with a larger engine (254 kW/340 hp Lycoming GSO-480-B1B6) and a three-blade propeller as the Do 27H-2.
In addition to the military operators in Germany and Spain, Portugal received 40 new build and 106 ex-German aircraft. The Portuguese Air Force used these extensively in the colonial war in Portuguese Africa during the 1960s-70s. In Guinea, in April 1973 two Do 27s were shot down by SAM-7 Grail shoulder launched AAMs.[3]
The Do 27 was notable for being the first mass-produced aircraft in Germany after World War II. It was appreciated for its relatively wide, comfortable cabin and excellent short-field performance.
