A series of significant transports followed under Oleg Antonov's direction. Antonov aircraft (design office prefix An-) range from a rugged An-2 (which itself is comparatively large for a biplane) through the An-28 reconnaissance aircraft to the massive An-124 Ruslan strategic airlifter. The quad-turboprop An-12 and its derivatives became the primary Soviet military transport from 1959 onward. While less well known, the An-24, An-26, An-30 and An-32 family of twin-turboprop, high winged, passenger/cargo/troops aircraft predominate in domestic/short-haul air services in the former Soviet Union and parts of the world formerly under Soviet influence. Antonov also oversaw development of the mid-range (An-72/An-74 jet airplanes family. The world's largest production aircraft, the An-124 Ruslan, flew for the first time in 1982, and its specialised shuttle-carrying/extra-heavy cargo derivative, the An-225 Mriya entered development, still under Antonov's guidance, but did not make its maiden flight until 1989 after the death of Antonov. In November 2004, FAI placed the An-225 in the Guinness Book of Records for its 240 records. Some of Antonov's designs are also built abroad, such as the Shaanxi Y-8.
