The Gryazev-Shipunov GSh-30-2 (ГШ-30-2) or GSh-2-30 is a dual-barrel autocannon developed for use on certain Soviet military aircraft. The cannon is not related to the Gryazev-Shipunov GSh-30-1, but is a recoil-operated cannon using the Gast principle, like the Gryazev-Shipunov GSh-23L. Its official claimed rate of fire is about 3,000 rounds per minute. Depleted uranium enhanced armor-piercing shells suitable for the GSh-30-2 are operationally qualified. The GSh-30-2 is carried by the Sukhoi Su-25 ground attack plane and in external gun pods. It measures 2044 × 222 × 195 mm, with a barrel length of 1500 mm and a weight of 105 kg. The GSh-30K is a modified version with 2400 mm long water-cooled barrels, a variable rate of fire, and dimensions of 2944 × 222 × 195 mm. It is used on a fixed mounting on late model Mi-24 helicopters, e.g. the Mi-24P. ==Specifications (GSh-30-2)== * Manufacturer: KBP Instrument Design Bureau * Type: dual-barrel automatic cannon * Caliber: 30x165 mm, electrically primed * Operation: Gast principle * Length: 2044 mm * Barrel Length: 1500 mm * Weight (complete): 105 kg * Rate of fire: 3000 rpm * Muzzle velocity: 870 m/s * Projectile weight: 390 g * Mounting platforms: Sukhoi Su-25 "Frogfoot" 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gryazev-Shipunov GSh-30-2」の詳細全文を読む スポンサード リンク
