Nation: DASH It All!

The Navy, turning to a new use of helicopters, is equipping each of its 250-odd destroyers with two unmanned, remote-controlled choppers to attack submarines. Developed by Long Island’s Gyrodyne Co. of America, Inc., the 1,600-lb., all-weather, buglike aircraft can lift off a destroyer, reach sonar-detected subs as far as 15 miles away, unleash two homing torpedoes and land back on the ship—all at the electronic command of shipboard officers. Called DASH (Drone Anti-Submarine Helicopter), the system is designed to strike submarines before they get within torpedo range of the destroyers.
