Helicopters to be replaced with drones in the Arctic

27 february 2024

Drones are planned to be used for ice exploration in the Arctic and they can replace expensive helicopters, said Oleg Devyataev, chief specialist of the Center for Ice and Hydro-meteorological Data of the Arctic and Antarctic Research Institute.

"Previously, the biggest obstacle to using UAVs was the difficulty of landing a drone on board a moving icebreaker or vessel in a difficult Arctic environment. However, now, after the completion of Rosatom's tests, we can say that this issue which has been hindering the development for a long time, has finally been solved," he said.

According to Devyataev, UAVs will transmit information about the ice situation directly to the ship's navigation bridge in real time.

The aircraft will also collect data on the hydrometeorological situation and the state of the ice cover on board the vessel. Icebreakers have already begun to be equipped with such complexes, sever-press.ru writes.
