, but lower weight and bulk. The GSh-30-1 has a rate of fire of 1,800 rounds per minute, customarily limited to 1,500 rounds per minute to reduce barrel wear. Despite that, its barrel life is quite short: 2,000 rounds, with a continuous burst rated for 150 rounds. The gun uses an evaporation cooling system to prevent the detonation of a high explosive round inside a heated barrel. This cooling system consists of a cylindrical water tank around the rear end of the barrel. The GSh-30-1 is equipped with a unique
