Explore the Antonov A-40, the Soviet Union's audacious WWII experiment to give a T-60 light tank wings to solve tactical bottlenecks on the Eastern Front.

The A-40 was a technical success in the sense that it flew and landed, but it was a total failure as a weapon system. It's a classic case of an engineering solution that creates three new problems for every one it solves.
The Antonov A-40 Krylya Tank: a comprehensive deep dive into its design, engineering story, WWII context, technical specifications, and flight testing history.

The Antonov A-40, also known as the Krylya Tanka or 'Tank Wings,' was an audacious Soviet engineering project during the Second World War. It was designed to solve the 'teeth' problem faced by paratroopers behind enemy lines by attaching a sixty-foot biplane wing assembly to a five-and-a-half-ton T-60 light tank. This experimental flying tank was intended to bridge the gap between airborne mobility and heavy ground firepower.
The Soviet Union developed the Antonov A-40 to address a classic tactical bottleneck where light infantry dropped behind German lines lacked the heavy armor needed to face Panzer divisions. By blurring the line between a tank and a glider, they hoped to create a vehicle that could glide silently into a battlefield. The goal was for the tank to shed its wings in seconds and begin firing immediately upon landing.
The experiment utilized a T-60 light tank, which weighed approximately five-and-a-half tons. Engineers bolted a massive wing assembly to the hull of the tank to transform it into the Antonov A-40. This 'mad science' approach represented the absolute limits of 1940s technology and the desperation of the Eastern Front, as the military sought ways to transport heavy armor at the speed of airborne units.
