Ukraine turns to sea drones in bid to take the war to Russia

The drones also appear to be composed of components that are readily commercially available and not hard to procure, involving a propulsion system derived from a civilian jet ski and guidance that seems to rely on satellite communications, said Sidharth Kaushal, a research fellow in sea power at the London-based Royal United Services Institute. Like aerial drones, they can also be quite cost-effective, he said. “So even if you lose a few, but you destroy an expensive warship or damage it, the model pays for itself.”
