Dart was an early – and enormous - anti-tank missile. Curtiss-Wright's first design proposal in November 1951. After evaluation against the French SS.10, a development contract was issued in April 1953. First launch was in August 1954. The missile was powered by a Grand Central dual-thrust solid-propellant rocket motor and was fired from an M59 truck-mounted launcher. The operator was supposed to optically control the wire-guided missile by siting on a tail-mounted sodium flare. The Dart's large cruciform wings and fins made its mobility questionable. It began to be advertised as an anti-emplacement weapon instead. Development dragged on, and the missile was finally cancelled in September 1958. The SS.10, much more compact and by then operational, was purchased for the Army instead.
