BAE Systems demonstrated the feat during a NATO training exercise, which saw a human controller fly the quadcopter strapped with the torpedo from a dock and over the ocean, where it let the weapon drop.
The electric-powered, car-sized T-600 has a payload capacity of 441 pounds, tops speeds of 87 miles per hour and has a range of up to 50 miles.
The demonstration aimed to showcase the anti-submarine warfare capabilities of the T-600 and its potential for automated logistics, resupply, casualty and evacuation.
