Sikorsky S-65 H-53

Sikorsky S-65 H-53

The Sikorsky S-65 is the western biggest helicopter and trace back to the 1962 US Marines Corps Heavy Helicopter Experimental (HHX) competition. The twin engined S-65 was developed as a scaled-up version of the S-61 but with the dynamic system of the S-64 Skycrane.

First flew on October 14, 1964 and this massive helicopter did it's first loops and rolls on March 1968 by a test pilot of the USMC.

Although dimensionally similar, the much more powerful three engined Sikorsky S-80 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.
