Paris, France – Turkish defence manufacturer Makine ve Kimya Endüstrisi (MKE) has unveiled the naval version of its TOLGA twin 20mm revolver cannon system at Euronaval 2026, held in Paris from November 3 to 6. The remotely operated system is designed to protect warships against close-range threats, including drones and unmanned surface vehicles (USVs).
Before its international debut, the naval TOLGA was tested aboard the Turkish Navy’s TCG Beykoz corvette during the TURNAs-2026 naval exercise in late October. According to MKE, the system successfully engaged aerial and surface targets during live-fire trials.
Twin Cannons and High Rate of Fire
The system features two 20mm gas-operated revolver cannons, each capable of firing up to 1,600 rounds per minute, giving the twin configuration a combined rate of 3,200 rounds per minute. The firing rate of each gun is adjustable, and both cannons can operate independently or together.
It uses 20×102mm ammunition, including conventional high-explosive (HE) rounds and MKE-developed fragmentation ammunition for counter-drone operations. The fragmentation rounds use predetermined detonation settings instead of programmable fuzes. A dual-feed system allows operators to switch between ammunition types.
The mount carries 600 rounds, stored in two 300-round containers. Operators can use short bursts of around 20 rounds to engage targets while conserving ammunition.
Independent Target Tracking and Stabilisation
A key feature is its four-axis configuration, comprising azimuth, elevation and two independent boresight axes. This allows the cannons to move separately from the electro-optical sensors. The sensors can maintain target tracking while the guns aim towards a predicted interception point.
The mount provides 360-degree coverage, an elevation range of +70 to -30 degrees and a maximum traverse speed of approximately 60 degrees per second. Its stabilisation system allows firing while the ship is moving.
The targeting suite includes daylight and thermal cameras and a laser rangefinder. Its fire-control system performs automatic ballistic calculations and supports day and night operations. The system can also integrate with a ship's combat management system, external radars and electronic warfare equipment.
Designed for Naval and Civilian Vessels
The naval TOLGA has a reported effective range of 2,000 metres with conventional ammunition and 1,000 metres with fragmentation rounds. The approximately 850 kg mount is driven by servo motors and can use its own inertial navigation system or connect to the ship's systems.
MKE is also offering the system for commercial vessels operating in higher-risk maritime areas, including deepwater drilling ships, seismic survey vessels, cable-laying ships and floating power plants.
The naval variant builds on earlier land-based TOLGA configurations. Its presentation at Euronaval 2026 follows the shipboard trials and expands the system's applications to naval platforms.
