Jyri Kosola, former head of research at the Finnish Defence Forces, has warned that Finland is falling behind as Russia expands its drone capabilities. Speaking on
, Kosola said Finland must act fast or risk being left behind in a key area of modern warfare.
“Time is short,” Kosola said. “Russia’s advancement in the field is quick. If Finland remains a mere spectator, we’ll be left behind.”
His comments follow a string of recent incidents involving Russian drones.
He added that future drones will become increasingly autonomous. Some of the latest prototypes imitate bird flight patterns, making them harder to detect. Others are designed for underwater use and are modelled on fish.
“These are not far-off ideas. Underwater drones shaped like fish are already in operation,” Kosola said.
After the drone incident in Poland, European Commission President
Ursula von der Leyen suggested a ‘drone wall’ to defend Europe’s eastern borders. NATO countries neighbouring Russia have since begun early planning on such a system.
Kosola said the word ‘wall’ was misleading and gave a false impression of a total barrier. He called the idea more of a ‘shield’ than a wall, and warned that the cost of protecting large borders using traditional fighter jets is unsustainable.
Last week, the Finnish Defence Forces told Yle they would respond to drone threats in a similar manner to Poland, by intercepting them with fighter aircraft. Kosola said such an approach is financially unrealistic over the long term.
“Shooting down a drone with a fighter jet costs millions,” he said. “That’s not a sustainable defence method.”
Kosola said Finland must take part in international defence efforts and increase investment in domestic drone systems. He stressed that a passive approach carries risks.
