The Silvercraft SH-4 is an Italian three-seater light helicopter designed and built by Silvercraft SpA as the first Italian helicopter to gain Italian and FAA certification. The prototype was first flown in October 1963 with development assisted with both financial and technical help from SIAI-Marchetti. The helicopter was a conventional design with two-blade main rotor and tail rotor, a skid landing gear and a high-set tubular corrugated tailboom. It is powered by either a 200hp (149kW) or 235hp {175kW) Franklin 6A-350 engines which have been flat-rated to 170hp (127kW). Two aircraft were evaluated by the Italian military.
An upgraded development, the SH-200 was developed from the SH-4 but was only flown as a prototype.
