History

After World War II, the Soviet Air Force worked to produce a faster-firing machine than their existing Berezin UB. Since reducing the cycle time would cause unacceptable levels of wear on the components and reduce the service life, Nikolay M. Afanasev decided to add an acceleration lever to a prototype design. The lever converted the energy from the short action of the slide into a long action for chambering and extraction. This weapon was tested under the designation TKB-481. Slated to be the defensive armament for the Tu-4 "Bull", the Soviet Air Force soon decided that machine guns were obsolete for bomber defensive armaments and the mounting of the NS-23 cannon. However, development continued with the TKB-481, which could fire at a rate of 1,400 rounds per minute. The focus of the program switched to helicopters such as the Yak-24 “Horse” which mounted this machine in a flexible mount. The issue of barrel wear persisted until the design was finally refined into the A-12.7 machine gun adopted in 1953.
