As last month’s grounding of flights at Heathrow Airport showed us, drones can cause a lot of problems – and they can even pose a security risk – when they’re flown in the wrong places. Engineers with the US Army are developing a countermeasure, in the form of a drone-netting grenade.
The experimental 40-mm grenade was invented by Tomasz Blyskal, Richard Fong and LaMar Thompson at the Picatinny Arsenal in New Jersey.
Individual soldiers could shoot it at rogue drones using M320 portable grenade launchers, while heavy weapons platoons could utilize larger Mk-19 launchers. The former setup could target drones hundreds of yards away, while the latter has an even longer range.
