421st Assault Aviation Regiment The 421st Assault Aviation Regiment was established on December 20, 1944, in
Laćarak, from
Yugoslav Partisan aviators serving with the
Soviet Air Force 17th Air Army's 165th Guards Assault Aviation Regiment (165.GShAP). It became independent from Soviet command and personnel in May 1945, and became part of the 42nd Aviation Assault Division, equipped with Soviet
Ilyushin Il-2 ground-attack aircraft. The regiment took part in the final operations of the
liberation of Yugoslavia, during which time it was based at Laćarak,
Krnješevci,

FPR Yugoslavia cc.1949. The 107th Assault Aviation Regiment remained at Niš for a short time, then in 1949 it was re-based at
Leskovac, where it remained until 1953, when it returned to Niš. In 1953, the Soviet Ilyushin Il-2 attack aircraft were replaced with Yugoslav-made
Ikarus S-49A fighter aircraft. The regiment was soon renamed the 107th Fighter Aviation Regiment (
Serbo-Croatian: 107. lovački avijacijski puk / 107. ловачки авијацијски пук) and in 1957, it was reequipped with the American-built
F-47D Thunderbolt. This resulted in yet another name change, when it became the 107th Fighter-Bomber Aviation Regiment (
Serbo-Croatian: 107. lovačko-bombarderski avijacijski puk / 107. ловачко-бомбардерски авијацијски пук). The P-47 remained in service with the regiment until 1960. On August 18, 1960, the regiment was converted into the 107th Helicopter Regiment (
Serbo-Croatian: 107. helikopterski puk / 107. хеликоптерски пук). It was equipped with Soviet-made
Mil Mi-4 and British
Westland S-55 helicopters. In 1961, with the "Drvar" re-organization of the Air Force, a new system was put in use to identify squadrons, and the three squadrons of the 107th Helicopter Regiment became the
780th, the
781st and the
782nd Transport Helicopter Squadron. In 1964, the
677th Transport Aviation Squadron was attached to the regiment, equipped with
Douglas C-47 Skytrain and
Lisunov Li-3 cargo aircraft. The following year, the
891st Liaison Aviation Squadron with Yugoslav-made
Ikarus Kurir monoplanes was also attached to the regiment. In 1966, the
783rd Helicopter Squadron was also assigned to the 107th Regiment. Other organizational changes included the
780th and
781st Transport Helicopter Squadron being reassigned to the
111th Support Aviation Regiment, and the
782nd Transport Helicopter Squadron being reassigned to the
81st Support Aviation Regiment. Both Mi-4 and S-55 helicopters remained in service until 1973. During the period 1964 to 1973, the regiment was known as the 107th Support Aviation Regiment. By 1973, the regiment was once again converted into a helicopter regiment and was transferred to
Mostar Airport, becoming part of the
Military Aviation Academy with its main task being helicopter training. It was originally equipped with Soviet-made
Mil Mi-2 helicopters, which were replaced in 1974 with Yugoslav-built
Soko SA.341 Gazelle helicopters. The regiment then consisted of the
782nd and the
783rd Helicopter Squadrons. In 1988, the 783rd Helicopter Squadron was renumbered as the
722nd Anti-Armored Helicopter Squadron, being equipped with the new
Soko SA.342 Gazelle Gama anti-tank helicopter. In the same year, the
334th Fighter-Bomber Aviation Squadron was attached to the 107th Regiment. In 1990, the 334th Fighter-Bomber Aviation Squadron was disbanded. The regiment was again renamed in 1991 as the 107th Mixed Aviation Regiment. It was used in combat operations in 1991 and 1992 during the
wars in Croatia and
Bosnia and Herzegovina. With the withdrawal of
Yugoslav People's Army units from
Bosnia and Herzegovina, the regiment moved in April 1992 from Mostar Airport to
Golubovci Air Base in
Montenegro. The regiment was disbanded in May 1992, with most of the regiment's equipment and personnel being transferred to the
722nd Squadron within the
97th Helicopter Regiment. The commanders of regiment in this period were Dimitrije Kovačević, Ljubo Vukčević, Slobodan Alagić, Radovan Daković, Miloš Bogdanović, Vojislav Mikić, Nikola Petrović, Vukadin Živković, Stevan Vukmanović, Života Pavković and Ivan Mihajlović. ==Assignments==
