The Royal Danish Navy has deployed four unmanned boats developed by U.S. company Saildrone to enhance patrols of underwater cables in the Baltic Sea. These boats utilize wind and solar power and also have a backup diesel engine. According to Saildrone CEO Jenkins, the vessels employ advanced machine learning and artificial intelligence to create comprehensive images of both the water surface and underwater. Their detection range extends from 232 to 48 kilometers.

Currently, two boats are participating in NATO's patrol tests, while the other two were delivered to the Danish Navy in mid-June. The Køge area, located on the eastern side of Bornholm Island, is strategically important for monitoring the Russian Navy and civilian vessels. In light of past incidents involving the destruction of the Nord Stream 1 pipeline and the Baltic Sea cables, NATO countries have been vocal in attributing these events to Russian actions.

Furthermore, Denmark aims to expand the patrol range to include Greenland, which has raised some controversies. However, the American company has clarified that the decision to extend operations in Denmark was made before Trump's return to the White House.
