Russia’s Kalashnikov Concern has fulfilled all 2025 contracts for GSh-301 30 mm aircraft cannons and is already preparing its 2026 production schedule, highlighting the continued importance of internal guns for maintaining high-tempo sortie generation and overall combat readiness.
On December 12, 2025, Kalashnikov Concern announced it had completed all 2025 contractual deliveries of GSh-301 aircraft automatic cannons, with shipments made on schedule and follow-on production already underway for 2026, highlighting the continued importance of secondary subsystems such as internal aircraft guns in sustaining operational availability, especially when barrel life, spare parts, and depot maintenance capacity limit combat aviation forces.
Internationally known as the Gryazev-Shipunov GSh-30-1, the GSh-301 is a single-barreled, short-recoil 30 mm aircraft cannon firing the 30×165 mm cartridge, a standard Soviet and Russian aviation caliber, valued for its low weight and high cyclic rate, typically 1,500–1,800 rounds per minute depending on configuration, making it ideal for fighter aircraft where space and mass are constrained.
Operationally, the GSh-301 offers aircrews immediate, close-range lethality without relying on missile availability or seeker performance, integrated with modern fire control systems to allow targeting through head-up displays and onboard sensors, delivering short, concentrated bursts within seconds, with effective ranges of hundreds of meters against aerial targets and over a kilometer against ground targets, serving as a last-resort weapon in air-to-air combat and a versatile option for strafing lightly protected ground targets.
For the customer, Kalashnikov did not disclose, continued production primarily supports readiness and sustainment of existing combat aircraft rather than introducing new capabilities, standard on fighters and strike aircraft such as the MiG-29, MiG-29K/KUB, Su-27, Su-30, Su-35, and Su-34, complementing guided weapons with a low-cost, flexible option for targets that do not require missiles or when visual confirmation and proportional force are mandated.
The 30×165 mm ammunition family includes high-explosive incendiary and tracer rounds designed for aerial and surface targets, with high muzzle velocities enabling flat trajectories, high impact energy, and the ability to damage lightly armored vehicles, radar systems, and field fortifications during brief attack windows.
Kalashnikov emphasizes the industrial dimension, using modern production equipment and high-alloy steels, increasing output in recent years, and positioning itself as Russia’s sole aircraft cannon manufacturer, highlighting the strategic significance of uninterrupted production during extended operational demand.
Beyond Russia, the GSh-301 remains relevant to many export customers operating Su-30 and MiG-29 variants, including India, Algeria, Malaysia, Indonesia, Kazakhstan, Angola, Armenia, China, and others, as the internal cannon continues to be a core element of baseline aircraft armament.
Tactically, the completed deliveries are significant not for technological innovation but for sustaining a proven, high-rate-of-fire capability essential for training realism, engagement flexibility, and mission effectiveness when precision-guided munitions are limited, conserved, or unsuitable.
