History
In the early years of the Cold War, the Yakovlev Design Bureau sought to regain prominence against strong rivals such as MiG and Sukhoi. In response to the Soviet Air Force’s 1955 call for a new frontal interceptor fighter, Yakovlev introduced the YA-11 Robber, an experimental design exploring swept-wing configurations and new turbojet engines with afterburners.

The first prototype, designated YA-11A, made its maiden flight in late 1954. It demonstrated remarkable high-altitude performance powered by the Klimov VK-9A engine, capable of reaching near Mach 1 speeds. However, the aircraft suffered from stability and maneuverability issues, along with higher maintenance demands compared to its competitors. The MiG-17F, being more agile and cost-effective, ultimately won the procurement competition.

Despite this, Yakovlev continued work on the project under limited internal backing. This effort led to the development of the YA-11 Robber B, a refined version featuring improved control systems, lighter composite materials, and an experimental Sokol-2 radar. Its ability to carry Vympel K-13 short-range guided missiles and its high thrust-to-weight ratio made it a powerful interceptor for regional defense and advanced training purposes.

Between 1956 and 1958, a small number of units were produced for field testing and limited deployment across air bases in the Caucasus and Central Asia. Although it never achieved widespread adoption, the YA-11 Robber B earned a reputation as a demanding yet formidable aircraft in the hands of skilled pilots.
