Ukraine presented the largest underwater drone Toloka-1000: details of the new weapon

At the Defense Tech Valley 2025 exhibition, Ukrainian developers presented a model of the largest underwater drone from the 'Toloka' family. This is a whole line of robotic underwater vehicles capable of performing tasks from reconnaissance to engaging targets at distances of up to 2000 km, reports the publication 'Military'.

New technology from company Toloka: model Toloka-1000

The developer company Toloka presented three models: Toloka-1000, Toloka-400, and Toloka-200. The largest of them - Toloka-1000 - is a diesel-electric underwater drone capable of carrying up to 5000 kg of payload and operating at depths of up to 1000 meters, with a range of up to 2000 km and an autonomy duration of up to three months.

'In practice, this is a diesel-electric underwater drone,' explained a representative of the company Toloka.

Thanks to the hybrid power system, the device can submerge for extended periods, and when the battery charge drops, it comes to the surface to recharge.

Younger models Toloka-400 and Toloka-200

In the Toloka lineup, there are several smaller models, including Toloka-400 and Toloka-200, each of which has its unique characteristics and purposes.

• Toloka-400: Has a range of up to 1200 km and can carry over 500 kg of payload.
• Toloka-200: An electric drone that can be used for reconnaissance or mining. Its speed is 15 knots, range - 100 km, and the weight of the warhead is 20 kg.

Drones 'Toloka': not torpedoes, but robotic platforms

Developers emphasize that their devices are not torpedoes, but fully functional robotic platforms designed for prolonged operation and reconnaissance. Thanks to a range of sensors and artificial intelligence, they can autonomously perform a wide variety of tasks in the maritime theater of operations.

Ukrainian developers showcased new 'Toloka' models at the Defense Tech Valley 2025 exhibition. The new underwater drones can operate at great depths, have significant flight ranges and autonomy durations. These robotic platforms are designed to perform various tasks in the maritime theater of operations thanks to modern technologies and artificial intelligence.
