The improvement of the DH-100 aircraft gave birth to the DH-112 Mk. 1 Venom, first flight on September 2, 1948. The Swiss Air Force became interested in this aircraft and tests were held in England and Switzerland in 1949 and 1950. In April 1951, the Federal Council's message concerning the authorized construction of 150 DH-112 Mk. 1 Venom aircraft was approved by the Federal Parliament with a commitment credit of 175 million francs. The license agreement included the Ghost-48 radial engine. It was produced by Gebrüder Sulzer AG and was installed in the aircraft from the 30th production aircraft. The Venom was the first Swiss Air Force fighter to be equipped with an ejection seat from the outset. In February 1954, the Parliament approved the construction of another 100 DH-112 Mk. 4 Venom aircraft under license. 226 DH-112 Mk. 1 and Mk. 4 aircraft were used by troops as ground combat aircraft from 1954 to 1983. 24 DH-112 Mk. 1R aircraft were used as reconnaissance aircraft by 10 Squadron from 1954 to 1968. This was the largest fleet that served Switzerland. The new nose cone, introduced in the 1970s, houses a new UHF radio, a bomb aiming computer and a friend and foe device (IFF). The Venom was retired in 1983. Our modeling is based on the latest MK4 version.
