The US isn't ready to detect and defend against hostile drone attacks, a detection company warned, echoing concerns raised by others about a growing threat.Drones have become a defining weapon in Ukraine and a growing threat in the Middle East, underscoring how cheap, accessible systems can create serious security challenges abroad and at home.Companies working on counter-drone technology warn that the US isn't ready to meet the threat."I'm very concerned," Kristian Brost, the general manager of the US division of Robin Radar, a company that makes drone-detection radars used by Ukraine and US allies and has contracts with the US, told Business Insider.When he first entered the counter-drone space in 2024, Brost assumed that the US had figured out solutions to this problem."What I'm finding in the US, that is not the case," he said."I'd say frankly, we're probably behind Europe" when it comes to implementing counter-drone technology, he added. And the problem with the US is that "only the very top elite kind of law enforcement organizations protecting very critical infrastructure have any kind of drone detection technology."
