Post-war, Marienburg, Germany, became Malbork, Poland; and Soviet Air force units were based there[specify] for a few years.[when?] In 1952 the 41st Fighter Aviation Regiment was formed to be based there, initially equipped with Mig-15 fighters, later replaced with Mig-17s, and from 1964 Mig-21s. In 2001 the regiment was dissolved and its ground and air components separated, to form the 22 Air Base[clarification needed] and 41st Air Tactical Squadron respectively. In 2003 the last Mig-21s were retired, and in 2004 the squadron was rearmed with refurbished Mig-29s obtained from Germany.
