[edit]Description330-PSA-54-63 (USN 711254) (22138360726).jpg | 330-PSA-54-63 (USN 711254): “DASH” on the flight deck of USS Hugh Purvis (DD 709), loaded with two homing torpedoes. The double-rotor helicopter is powered by a Boeing 300 HP Engine, March 7, 1963. Master caption: Drone Anti-Submarine Helicopter (DASH). Dash, a remote-controlled anti-submarine weapon, built by the Gyrodyne Company of America, Inc., recently completed operational evaluation flights at sea onboard USS Hugh Purvis (DD 709). A pilotless aircraft, DASH, is an all-weather system designed to extend the range of a destroyer’s anti-submarine arsenal. It possesses a “stand-off” capability for destruction of enemy submarine before they can approach to within torpedo attack range. The drone carries two homing torpedoes. When contact is made with a submarine, the craft is flown by remote control to the vicinity of the contact, drops it torpedoes and is recovered aboard the destroyer, one on the flight deck, another in the Combat Information Center (CIC). Personnel on the flight deck control the take-off, initial flight toward the target, and landing under visual conditions. When DASH appears on the ship’s radar, control is assumed at the CIC station and the helicopter is maneuvered to the contact and its torpedoes dropped. It is controlled back to the ship on radar until the flight deck personnel pick it up visually for landing. (2015/10/13). |
