Toloka TLK-150
A compact selection from this profile, with sources and limits. Other configurations and additional measurements remain in the full profile.
A Ukrainian underwater-drone development publicly displayed through the Brave1 ecosystem, with a small TLK-150 configuration and later visible redesign. Sutton’s 2023 analysis and Militarnyi’s 2025 comparison concern different displays. They support a substantial programme history and configuration distinction, but do not establish operational acceptance or an independently measured long-distance underwater mission.[1][2]

Form, sound & identification limits
- Sutton’s original 2023 analysis identifies a submerged body with an above-water mast and explicitly leaves operational use unclear. Whether “underwater” or “semi-submersible” is preferred depends on which part remains exposed; the label alone does not certify a depth capability.[1]
- Militarnyi’s 2025 report compares the updated smallest model with the 2023 display. It is a separate authored visual analysis, not a second completed-distance trial. Old dimensions and range ambitions are not automatically assigned to the redesigned craft.[2]
- TLK-400 and TLK-1000 are other proposed family members. Their dimensions, payload and range are not TLK-150 specifications. The reviewed record does not justify a current measured envelope, universal speed or cost figure; these remain unknown.[1][2]
Shape or sound alone cannot identify a drone. Follow local public-safety alerts; do not approach wreckage.
