During the war with Russia, Ukraine became known for finding unconventional solutions to combat Russian aggression in the Black Sea.. An example is the underwater drone of the Brave 1 Toloka TLK-150 project, Naval News writes about the features of the Ukrainian development.

One of these solutions is the creation of an unmanned submarine Toloka TLK-150. This is a relatively small drone with a length of only 2.5 meters.

It has twin engines, thrusters on small wing-shaped stabilizers and a large keel.. Together with other design features, the marine device received high maneuverability.

The publication suggests that the drone camera can be used as a periscope for intelligence gathering missions near the enemy coast.. Also, the camera can help the underwater drone to aim during the attack..

Toloka TLK-150 is significantly smaller than previous Ukrainian maritime drones. He probably has a much shorter range and slower speed, but makes up for this by being more stealthy and living..

Naval News reports that in addition to the TLK-150, Ukraine has projects for larger models of this series - TLK-400 and TLK-1000.

The length of TLK-400 is 4-6 meters. It also has a much larger diameter hull, which means longer range and more payload.. The TLK-1000 has even larger dimensions - 12 meters in length and four engines at once.

At the same time, the publication does not have information whether the TLK-400 and TLK-1000 models are already ready for serial production or are in the process of development..

Ukraine has already achieved significant strategic success, pushing the Russian fleet, which initially dominated the northern Black Sea, to a defensive position..

The threat of anti-ship missiles, like those that sank the cruiser Moskva, pushed the Russian fleet back. However, Russians can still work there to launch missiles or support ground operations if necessary..

In November last year, fundraising platform UNITED24 started raising funds to create a Ukrainian fleet of sea drones..

The first such marine drone at the end of October hit three Russian ships, including the flagship of the Black Sea Fleet of the Russian Federation "
