Russia's Su-25: Moscow's 'A-10' Is a Virtual 'Flying Tank'
With the dissolution of the Soviet Union, Su-25s were passed onto the air services of all the Soviet successor states. Those that didn’t use Su-25s in local wars—on both sides of the Nagorno-Karabakh conflict, for example—often exported them to countries that did. Frogfoots have seen action in the service of Macedonia (against Albanian rebels), Ethiopia (against Eritrea, with one shot down), Sudan (target: Darfur), and Georgia versus Abkhazian separatists that shot down several. And that list is not comprehensive.
The Su-25 Frogfoot, known as the Grach or “Rook” by Russian pilots, is one of those aircraft that may not be at the cutting edge of technology, but still has seen widespread service around the world because it offers an effective and useful solution to the need to blast targets on the ground.
As such, its obvious stablemate is the American A-10 Thunderbolt II attack plane. But while the U.S. Air Force wants to retire the A-10 starting in 2022, the Su-25 is undergoing extensive upgrades to keep with the times.

Also unlike the Thunderbolt, it has been disseminated it all over the world and seen action in over a dozen wars, including in the air campaigns over Syria, Iraq and Ukraine.
Not only has Russia had a lot of experience flying Su-25s in combat—it has shot several down as well.

During World War II, Russia’s armored Il-2 Sturmovik attack planes, nicknamed “Flying Tanks,” were renowned for their ability to take a pounding while dishing it out to German Panzer divisions with bombs, rockets and cannon fire.
Unlike the U.S. Air Force in the 1960s, which was enamored with the concept of “winning” nuclear wars with strategic bombers, the Soviet air service, the VVS, placed more emphasis on supporting ground armies in its Frontal Aviation branch. However, no worthy successor to the Shturmovik immediately appeared after World War II
In 1968, the VVS service decided it was time for another properly designed flying tank. After a three-way competition, the prototype submitted by Sukhoi was selected and the first Su-25 attack planes entered production in 1978 in a factory in Tbilisi, Georgia. Coincidentally, the American A-10 Thunderbolt had begun entering service a few years earlier.
Like the A-10, the Su-25 was all about winning a titanic clash between the ground forces of NATO and the Warsaw Pact by busting tanks and blasting infantry in Close Air Support missions. This meant flying low and slow to properly observe the battlefield and line up the plane for an attack run.
Flying low would also help the Su-25 avoid all the deadly long-range SAMs that would have been active in a European battlefield. However, this would have exposed it to all kinds of antiaircraft guns. Thus, the pilot of the Su-25 benefited from an “armored bathtub”—ten to twenty-five millimeters of armor plating that wrapped around the cockpit and even padded the pilot’s headrest. It also had armored fuel tanks and redundant control schemes to increase the likelihood of surviving a hit. And in their extensive combat careers, Su-25s have survived some really bad hits.
Despite the similarities with the A-10, the Su-25 is a smaller and lighter, and has a maximum speed fifty percent faster than the Thunderbolt’s at around six hundred miles per hour. However, the Frogfoot has shorter range and loiter time, can only operate at half the altitude, and has a lighter maximum load of up to eight thousand pounds of munitions, compared to sixteen thousand on the Thunderbolt.
More importantly, the types of munitions usually carried are typically different. The Thunderbolt’s mainstays are precision-guided munitions, especially Maverick antitank missiles, as well as its monstrous, fast-firing GAU-8 cannon.
