Toloka Preparing for Serial Production of TOLOKA-400 and TOLOKA-200 Underwater Drones

At Defense Tech Valley 2025, Militarnyi spoke with a representative of Toloka, a company that develops underwater drones.

A video of this conversation has also been published on our YouTube channel.

TOLOKA-1000 is a diesel-electric autonomous vehicle with a composite body. It can dive to a depth of 1,000 meters, has a diameter of 1.5 meters, and can carry up to 5 tons of payload.

The drone is equipped with a rechargeable battery and electric motors. The submarine can operate for up to three months when recharged by a diesel generator. It performs monitoring, reconnaissance, surveillance, and strike missions. The range is up to 2000 km and the speed is 5 to 15 knots.

Testing of onboard equipment is currently underway. After that, the drone is scheduled to undergo sea trials. If the results are positive, the drone will be put into mass production. At the same time, the company is preparing the TOLOKA-400 and TOLOKA-200 models for mass production.

TOLOKA-400 has a range of 1200 km, a payload of over 500 kg, and a gasoline engine. The body can be composite or metal.

The metal version of TOLOKA-400 can be submerged to a depth of 30 meters. The drone is capable of conducting search operations or acting as a kamikaze.

TOLOKA-200 is a small drone with a range of 200 km, a payload of 20 kg, and a speed of over 15 knots. It is equipped with inertial navigation, radio communication, internet, and a radio frequency guidance radar.

This vehicle can perform mining, reconnaissance, mine detection, attack as a kamikaze drone, and operate at shallow depths.

All drones can operate autonomously or in groups united by an IP protocol. They ‘communicate’ with each other via acoustic modems or radio. Above the water, they are controlled via satellite communications, while underwater they are guided by inertial navigation.

The models are equipped with artificial intelligence to recognize ships by acoustic signatures. The manufacturer uses imported engines, electronics, sonars, gyroscopes, navigation equipment, and hydrophones.

They can also scan the bottom or an area and perform mapping.
