The Sukhoi Su-25 was designed as a low level attack aircraft used in support of ground forces, much like the A-10 Thunderbolt II. Titanium, 24 mm thick, is used to protect the cockpit and other vital components from ground fire, while the internal fuel tanks are lined with a special foam to help protect against explosion. A two-seat variant was later designed as the Su-25UB, and an un-armed version was built the Sukhoi Su-25UT, which later became the Su-28. Poor combat performance of the Su-25 in Afghanistan led to a much improved ’Frogfoot’, named the Su-39. Designed from the Su-25UB, the Su-39 included wing-tip ECM pods, chaff/flare dispensers, IR jammer, and a new navigation and attack system which provided fully automatic weapon selection and release.
