It took just minutes for a new Greek-made anti-drone system to show what it is capable of.

On its first test run with a European Union patrol in the Red Sea a year ago, the Centauros system detected and swiftly brought down two aerial drones launched by Yemen¡¯s Houthis, who have been attacking merchant vessels in the busy shipping lane.

Another two drones swiftly retreated: Centauros had jammed their electronics, said Kyriakos Enotiadis, electronics director at state-run Hellenic Aerospace Industry (HAI), which produces the anti-drone system.
