The Su-25 ground attack aircraft entered service with the Soviet Air Force in 1984. The Su-25UB is a two-seat derivative of the Su-25 designed to provide training. This aircraft has been purchased by several countries. Approximately 300-400 Su-25s have been produced to date. The Su-25SMK is being offered as an inexpensive modernization option for existing Su-25K aircraft. It includes a new cockpit instrumentation, new avionics, a radar warning system, a new weapon system, a GPS-based (NAVSTAR or GLONASS) navigation system and a new IFF transponder. The Su-25UBMK is a two-seat trainer version of the same upgraded aircraft. As of October 2008, the Russian Air Force plans call for keeping the upgraded Su-25SM equipped with GLONASS navigation system in active duty through 2020.

The Su-39, also known as the Su-25T or Su-25TM, is a derivative of the proven Su-25UB training aircraft with enhanced anti-tank features. Additional armor, reduction in thermal signature and increased weapons load through 11 pylons has been provided to Su-39 aircraft as well as compatibility with latest Russian precision-guided weapons. It can accommodate a pod-mounted radar for guidance of advanced weapons such as R-73, R-77, R-27, Vikhr, and Kh-31 missiles. These weapons provide enhanced anti-tank capability (Vikhr missile), new anti-ship and anti-radiation capability (Kh-31) and medium-range air-to-air capability (remaining missiles). The Russian Air Force intends to upgrade current Su-25 ground attack aircraft to the Su-39 configuration. The new high-performance aircraft is available for export.

The Russian Air Force Su-25SM3, also known as Supergrach, is an upgraded variant of the Su-25SM ground attack aircraft. The Su-25SM3 Supergrach is a further version with better air-to-ground engagement capabilities introduced in 2017. The Su-25SM3 is equipped with the Vitebsk protection system designed against fire from Man Portable Air Defense Systems (MANPADS) such as Stinger and Igla missile system. The new variant features GLONASS positioning aids for navigation and to conduct strikes on the ground with an accuracy of less than 10 meters even in conditions of poor visibility. A new array of self-guided bombs and missiles may be added to the Su-25SM3 aircraft along with the capability of flying at speeds between 100 kilometers per hour (kph) to roughly 1,000 kph without stalling.
