Denmark has ordered four unmanned boats from the American company Saildrone. These boats are powered by wind and solar energy, with a backup diesel engine. Saildrone CEO Jenkins stated, "We use precise machine learning and artificial intelligence on the vessels to integrate data and create a complete picture both above and below the water surface. We employ radar, optical and infrared cameras, along with radio and underwater acoustics to maximize our detection range, which can reach up to 232 kilometers or approximately 48 miles."

On June 6, two of these boats joined NATO's patrol tests, with another two handed over to the Danish Navy on the 16th. Positioned at Klerø, on the eastern side of Bornholm Island, this area holds strategic value as a gateway to the North Atlantic, making it an ideal location for NATO to monitor both the Russian navy and civilian vessels.

Following incidents such as the destruction of the Nord Stream 1 gas pipeline in 2022 and the sabotage of undersea cables in the Baltic Sea in 2024, NATO countries along the Baltic Sea have unambiguously blamed Russia, even in the absence of concrete evidence. In addition to increasing the intensity of exercises in the Baltic Sea, the deployment of unmanned boats represents a specific course of action. Danish Royal Defense Academy Assistant Professor Jackson emphasized tracking every Russian vessel is cost-prohibitive, thus finding a 'cheaper' alternative is necessary.

According to reports from the Associated Press, Denmark aims to expand its patrol range to Greenland, which raises numerous speculations regarding its relations with the U.S. However, representatives from the American firm have stated that their collaboration with Denmark was decided before Donald Trump's return to the White House and is unrelated.
