Underwater vehicle symbol

Toloka TLK-150

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]

The numbers, with their sources

Intervals preserve the published bounds; they are not statistical confidence intervals. A blank lower or upper bound stays open. Values belong to the named configuration, not every aircraft.

One scale. Different machines.

No scaled drawing is provided for this configuration. See the sourced dimensions and their limitations.

Human height is an illustrative 1.8 m; bus length an illustrative 12 m. Car length uses the cited MINI specification. Vehicle heights and drone side contours are schematic. Top views preserve published length and span; an absent dimension is never guessed.

One car length here is 3.821 m: MINI Cooper 3 door, March 2020 specification.

Family & configurations

Toloka TLK-150

No sourced family relationship recorded in this edition. Similar roles do not establish a common design.

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.

No licensed, model-attested recording is available in our sound library.

What does it cost?

Published USD figures use different price bases and years. Airframes, export packages and support are not equivalent. These are not current offers or verified production costs.
