Sukhoi Su-25K
The export Frogfoot — flown by Czechoslovakia, Bulgaria and their successors · Built 1984–1989 · Tbilisi export series
The Su-25K (Kommercheskiy, 'commercial') was the export version of the basic Su-25, built at the same Tbilisi factory and differing only in minor details of internal equipment. A total of 180 were produced between 1984 and 1989, with two-seat Su-25UBK trainers built alongside them at Ulan-Ude.
Czechoslovakia's fleet was split 2:1 when the country divided in 1993. The Czech Republic inherited 24 Su-25Ks and one Su-25UBK and retired them in December 2000; twelve were later sold to Georgia. Slovakia received 12 Su-25Ks and one UBK, based at Malacky-Kuchyňa, and sold ten Su-25Ks and the UBK to Armenia in 2004.
Bulgaria received its first Su-25Ks and Su-25UBKs in 1985 and by 2004 had twenty Su-25Ks and three UBKs operational at Bezmer Air Base. Part of the fleet was modernised in Belarus, and The Military Balance listed five Su-25Ks and one UBK still in Bulgarian service in 2025.
