Sukhoi Su-25 Frogfoot (Wallpaper 4) attack aircraft remains the mainstay of Russian ground-attack regiments. The type is broadly analogous to the US A-10 but has been matured into a more sophisticated warplane. The T-8 prototype made it's first flight on 22 February 1975, but type was comprehensively redesigned before series production was authorized. It is intended to support ground forces, destroy heavy armored vehicles, fortifications and other targets. The Su-25 "Frogfoot" is some kind of competitor to the US A-10 "Thunderbolt" attack aircraft. Comparing them "Frogfoot" is significantly smaller, lighter but features more powerful armament and speed. Also the Su-25 has lighter protection than the "Thunderbolt". It is explained that US designers paid more attention to develop aircraft with good survivability while soviet designers developed smaller aircraft with better maneuverability that is harder to hit. Furthermore Sukhoi Su-25 Frogfoot (Wallpaper 4) was completed with more powerful turbojet engines instead of turboprop on the A-10. Weapons available include a double-barrel 30-mm cannon with 250 rounds, and underwing capacity for 4.4 tones of ordnance on 8 pylons. This disposable ordnance can include unoperated rockets, laser-guided rocket proprlrd bombs, "dumb" bombs of incendiary, anti-personnel, and chemical types, Air-to-Air missiles for self-defense, Air-to-Ground missiles, Anti-tank missiles. "Frogfoot" features a 24-mm welded titanium cockpit armor tub, an air mixing duct system to cool engine exhaust, and other survivability features like foam-filled fuel tanks and pushrod-actuated control surfaces. In addition, 256 flares or chaff dispensers are carried near the rear of the aircraft in the tailcone and above the engine exhausts. The laser designator and target indicating electronics are carried in the extreme nose. The Su-25T is an improved version of the Su-25. As "Frogfoots" flew some 60 000 combat sorties in Afghanistan and this experience led to a range of modifications applied to production aircraft from 1987. The need for an al-weather and night capable Su-25 with increased range, endurance and survivability led to the Su-25T ("T" for "Anti-tank"). This is based on the airframe of the Su-25UB two-seat trainer version with the humped rare cockpit faired over. This space now holds a fuel cell and extra avionics. An early batch of 20 Su-25Ts was built during 1990-1991 in Tbilisi (Georgia). Sukhoi Su-25 Frogfoot (Wallpaper 4)
