On July 18, 1951, nine helicopters from HMR-161 participated in a demonstration at Camp Pendleton for the purpose of introducing the press to the Marine Corps doctrine for using helicopters in modern warfare.

The HRS-1 was an innovative new design, designated by Sikorsky as the S-55. By placing the radial engine in the nose, Sikorsky engineers not only solved the center-of-gravity issues of earlier designs, they also made it easier to maintain the helicopter. More important, the resulting interior space could be used to carry fully equipped combat troops or cargo. The opportunities literally opened up by this expanded space would soon be demonstrated by HMR-161. Marines had been experimenting with the concept of air assault and supply by helicopters since 1949. Now it could—and would—be put into wartime practice in dramatic fashion.

On September 13, HMR-161 conducted operation Windmill I, history’s first mass helicopter resupply mission, lifting an impressive 18,848 pounds of combat gear seven miles to a Marine battalion on the front lines and evacuating 74 casualties. Amazingly, the squadron accomplished all that work within just one hour
