During the DSEI 2025 exhibition in London, the Latvian startup SUBmerge Baltic introduced its autonomous underwater drone named Pike. According to Army Recognition, this device is designed for monitoring and mapping underwater objects near critical infrastructure.

The drone can operate in both controlled and fully autonomous modes, allowing it to inspect pipelines and cables underwater for potential damage.

In controlled mode, the drone can function for up to eight hours at distances of several hundred meters, making it suitable for detailed inspections or port operations. In autonomous mode, it can operate for several days at distances of hundreds of kilometers, although this is dependent on weather conditions and payload weight.

Pike features a modular frame that allows for sensor changes without needing to return to the factory. While it is known that the drone is powered by batteries, its specifications have not been disclosed. Furthermore, the underwater drone can be launched from a small boat or directly from a pier.

The publication notes that underwater security is a current priority for NATO in light of several incidents involving damaged cables and pipelines in the Baltic Sea. Therefore, Pike could play a significant role in defense structures.

While the drone itself cannot stop saboteurs or replace escort teams or satellite monitoring, it can reduce blind spots and lower costs for scheduled inspections.

Previously, the German company EUROATLAS introduced the new underwater drone Greyshark, which is available in two variants and can autonomously change its tasks thanks to artificial intelligence.
