From a distance they look almost like ordinary sailboats, their sails emblazoned with the red-and-white flag of Denmark. However, these 10m-long vessels carry no crew and are designed for surveillance.
Four uncrewed robotic sailboats, known as “Voyagers,” have been put into service by Denmark’s armed forces for a three-month operational trial.
Built by Alameda, California-based company Saildrone, the vessels are to 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 on Monday from Koge Marina, about 40 km south of Copenhagen. Powered by wind and solar energy, the 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 30km to 50km in the open ocean.
Maritime threats such as damage to undersea cables, illegal fishing, and the smuggling of people, weapons and drugs are going undetected simply because “no one’s observing it,” he said.
Saildrone is “going to places ... where we previously didn’t have eyes and ears,” he said.
The Danish Ministry of Defense says the trial is aimed at boosting surveillance capacity in undermonitored waters, especially around critical undersea infrastructure such as fiber-optic cables and power lines.
“The security situation in the Baltic is tense,” said Lieutenant General Kim Jorgensen, director of Danish National Armaments at the ministry. “They’re going to cruise Danish waters, and then later they’re going to join up with the two that are on [the] NATO exercise. And then they’ll move from area to area within the Danish waters.”
The trial comes as NATO confronts a wave of damage to maritime infrastructure — including the 2022 Nord Stream pipeline explosions and the rupture of at least 11 undersea cables since late 2023. The most recent incident, in January, severed a fiber-optic link between Latvia and Sweden’s Gotland island.
The trial also unfolds against a backdrop of trans-Atlantic friction — with US President Donald Trump’s administration threatening to seize Greenland, a semiautonomous territory belonging to Denmark, a NATO member. Trump has said he would not rule out military force to take Greenland.
Jenkins said that his company had already planned to open its operation in Denmark before Trump was re-elected.
He did not want to comment on the Greenland matter, saying the company is not political.
Some of the maritime disruptions have been blamed on Russia’s so-called shadow fleet — aging oil tankers operating under opaque ownership to avoid sanctions.
One such vessel, the Eagle S, was seized by Finnish police in December for allegedly damaging a power cable between Finland and Estonia with its anchor.
Western officials accuse Russia of being behind a string of hybrid war attacks on land and at sea.
Amid these concerns, NATO is moving to build a layered maritime surveillance system combining uncrewed surface vehicles like the Voyagers with conventional naval ships, satellites and seabed sensors.
“The challenge is that you basically need to be on the water all the time, and it’s humongously expensive,” said Peter Viggo Jakobsen of the Royal Danish Defense College. “It’s simply too expensive for us to have a warship trailing every single Russian ship, be it a warship or a civilian freighter of some kind.”
“We’re trying to put together a layered system that will enable us to keep constant monitoring of potential threats, but at a much cheaper level than before,” he added.
‘HYANGDO’: A South Korean lawmaker said there was no credible evidence to support rumors that Kim Jong-un has a son with a disability or who is studying abroad South Korea’s spy agency yesterday said that North Korean leader Kim Jong-un’s daughter, Kim Ju-ae, who last week accompanied him on a high-profile visit to Beijing, is understood to be his recognized successor. The teenager drew global attention when she made her first official overseas trip with her father, as he met with Chinese President Xi Jinping (習近平) and Russian President Vladimir Putin. Analysts have long seen her as Kim’s likely successor, although some have suggested she has an older brother who is being secretly groomed as the next leader. The South Korean National Intelligence Service (NIS) “assesses that she [Kim Ju-ae]
In the week before his fatal shooting, right-wing US political activist Charlie Kirk cheered the boom of conservative young men in South Korea and warned about a “globalist menace” in Tokyo on his first speaking tour of Asia. Kirk, 31, who helped amplify US President Donald Trump’s agenda to young voters with often inflammatory rhetoric focused on issues such as gender and immigration, was shot in the neck on Wednesday at a speaking event at a Utah university. In Seoul on Friday last week, he spoke about how he “brought Trump to victory,” while addressing Build Up Korea 2025, a conservative conference
DEADLOCK: Putin has vowed to continue fighting unless Ukraine cedes more land, while talks have been paused with no immediate results expected, the Kremlin said Russia on Friday said that peace talks with Kyiv were on “pause” as Ukrainian President Volodymyr Zelenskiy warned that Russian President Vladimir Putin still wanted to capture the whole of Ukraine. Meanwhile, US President Donald Trump said that he was running out of patience with Putin, and the NATO alliance said it would bolster its eastern front after Russian drones were shot down in Polish airspace this week. The latest blow to faltering diplomacy came as Russia’s army staged major military drills with its key ally Belarus. Despite Trump forcing the warring sides to hold direct talks and hosting Putin in Alaska, there
North Korea has executed people for watching or distributing foreign television shows, including popular South Korean dramas, as part of an intensifying crackdown on personal freedoms, a UN human rights report said on Friday. Surveillance has grown more pervasive since 2014 with the help of new technologies, while punishments have become harsher — including the introduction of the death penalty for offences such as sharing foreign TV dramas, the report said. The curbs make North Korea the most restrictive country in the world, said the 14-page UN report, which was based on interviews with more than 300 witnesses and victims who had
