The Piasecki PD-22 was a development of the U.S. Navy's HRP-2.  First flown in 1952, the U.S. Air Force designated this helicopter the H-21 Workhorse.

The U.S. Army also ordered the H-21 naming it the Shawnee.  The Shawnee could carry 20 fully-equipped troops into combat, which it did in Vietnam.

In production from 1954 - 1959, the H-21 was flown by the armed forces of the U.S., Canada, France and West Germany.  The H-21 was also known as the Flying Banana.
