From the harsh mountains of Afghanistan to the complex modern conflicts of today, the Su-25 has carved out an enduring legacy as a resilient, effective, and utterly indispensable close air support aircraft.

From Cold War Necessity to Battlefield Dominance: The Su-25's Genesis

The story of the Su-25 begins in the late 1960s, when the Soviet Ministry of Defense recognized a critical gap in its air force capabilities. Existing fighter-bombers, while fast, lacked the armor and low-speed maneuverability essential for effective close air support. They were too vulnerable to ground fire and too quick to maintain visual contact with targets. This realization spurred a competition among Soviet design bureaus to create a specialized armored assault aircraft, a shturmovik.

Pavel Sukhoi and his team at the Sukhoi Design Bureau rose to the challenge, developing the T-8 design. The first prototype took to the skies on February 22, 1975, marking the birth of an aircraft that would redefine close air support. The Su-25 quickly outshone its competitors, leading to series production commencing in 1978 in Tbilisi, then part of the Georgian Soviet Socialist Republic. This meticulous development process, driven by the lessons of past conflicts, ensured the Su-25 was purpose-built for survival and effectiveness in the most demanding environments.

A Closer Look at the Frogfoot: Design, Capabilities, and Features

Its conventional aerodynamic layout features a shoulder-mounted trapezoidal wing, a robust airframe constructed from 60% aluminum, 19% steel, and a significant 13.5% titanium. This blend of materials contributes to its legendary toughness. The pilot is ensconced in a formidable titanium tub, designed to withstand direct hits from 12.7mm rounds, a testament to the aircraft’s emphasis on pilot protection. Even the front windshield is bulletproof, offering an additional layer of security. A unique titanium panel separates the twin engines, protecting one from shrapnel if the other is damaged.

Powering the Frogfoot are two R-95Sh non-afterburning turbojets, housed in compartments on either side of the rear fuselage. These engines, along with their sub-assemblies and surrounding fuselage, are cooled by an intricate air system, ensuring reliability under strenuous conditions. The aircraft’s wings are equipped with five hardpoints each, capable of carrying a diverse array of weaponry, mounted on load-bearing ribs and spars. These include a five-section leading edge slat, a two-section flap, and an aileron, all contributing to its maneuverability at low altitudes.

When it comes to armament, the Su-25 is a formidable platform. It boasts an internal 30mm GSh-30-2 double-barrel autocannon, fed by 250 rounds, known for its exceptionally high rate of fire. Its ten hardpoints can carry up to 4,000 kg of ordnance, ranging from unguided rockets and conventional bombs to advanced laser and TV-guided munitions. The outermost pylons are often reserved for air-to-air missiles like the infrared-guided R-60 (NATO: AA-8 Aphid), while the innermost can be fitted with external fuel tanks for extended range. Chaff and flare dispensers (ASO-2V) further enhance its survivability against missile threats.

The Frogfoot in Action: A History of Combat Operations
