Sikorsky S-65 / S-80

H-53 Series


The Sikorsky S-65/S-80, is the western largest transport helicopter and trace back to the 1962 US Marines Heavy Helicopter Experimental (HHX) competition. The twin engined S-65 entered service in 1966. Although dimensionally similar, the much more powerful three engined Sikorsky S-80E entered service in 1981 with one more main blade rotor and tail making a 20° angle to offset the thrust required on the tail rotor to keep it straight.
