Encyclopedia - Sikorsky H-53 Sea Dragon/Super Stallion

Developed to be the most powerful helicopter outside of the Soviet Union, the CH-53 Super Stallion boasted twin turbines ranging from two 2850 hp each in the oldest version (General Electric T64-6) to three T64-415 turbines producing a colossal 4380 hp each.

The CH-53 had the main rotor, gearbox controls in common with the S-64 Skycrane, but utilized titanium incorporated and fold able blades.

Most CH-53 served in Vietnam where they performed multiple tasks including the recovery of downed aircraft. In 1968 a standard CH-53A completed continuous loops while other variants set records for payload and speed.

A total of 153 CH-53D's were build for the German Army in Germany. Even the power plants were produced in Germany.

The CH-53 is capable of 18 ton sling load.
