This Su-7BM was delivered into Czechoslovakia in July 1964 to 28. sbolp (fighter-bomber regiment) at Caslav AFB. In 1980 was Sukhoi transfered to 20. sbolp in Namest nad Oslavou and later after 1 252 flying hours was in March 1985 withdrawn from duty.
These Czechoslovakian Su-25 was one of the first former Warsaw Pact aircraft I saw. This aircraft was transferred to the Slovak air force when Czechoslovakia broke up in 1993.
