Denmark has [1]deployed four uncrewed robotic sailboats (known as "Voyagers") for a three-month trial to boost maritime surveillance amid rising tensions in the Baltic region. The Associated Press reports:

> Built by Alameda, California-based company Saildrone, the vessels will patrol Danish and NATO waters in the Baltic and North Seas, where maritime tensions and suspected sabotage have escalated sharply since Russia's full-scale invasion of Ukraine on Feb. 24, 2022. Two of the Voyagers launched Monday from Koge Marina, about 40 kilometers (25 miles) south of the Danish capital, Copenhagen. Powered by wind and solar energy, these sea drones can operate autonomously for months at sea. Saildrone says the vessels carry advanced sensor suites -- radar, infrared and optical cameras, sonar and acoustic monitoring. Their launch comes after two others already joined a NATO patrol on June 6.

> Saildrone founder and CEO Richard Jenkins compared the vessels to a "truck" that carries sensors and uses machine learning and artificial intelligence to give a "full picture of what's above and below the surface" to about 20 to 30 miles (30 to 50 kilometers) in the open ocean. He said that maritime threats like damage to undersea cables, illegal fishing and the smuggling of people, weapons and drugs are going undetected simply because "no one's observing it." Saildrone, he said, is "going to places ... where we previously didn't have eyes and ears." The Danish Defense Ministry says the trial is aimed at boosting surveillance capacity in under-monitored waters, especially around critical undersea infrastructure such as fiber-optic cables and power lines.
