Fifty aircraft were put into service with the Czechoslovakian Air Force starting in 1958, with the majority being locally manufactured models that were delivered from 1968 onwards.
The majority of these aircraft were decommissioned before the division of Czechoslovakia, although a few may have briefly served with the newly formed successor states.
