It is intended to equip attack aircraft (Su-25, Su-39). The basic sample of a unified system for 30-mm rapid-fire artillery weapons.
- the use of common components and assemblies serving both barrels implements high-speed artillery equipment practically in dimensions and mass of single-barreled systems;
- barrel survivability issues are resolved by distributing the queue length between two trunks and reducing fire rate per barrel.
- high fire rate (up to 3500 shots/min) is achieved by the implementation of the full alignment of the main operations of the double-barreled scheme in time - preparation of the shot, striking the churning of the cartridge, sufficient uniformity of the tape feed .
