Sikorsky R-5 / HO2S-1 / HO3S


The second helicopter designed by Igor Sikorsky for the military was the two-seat R-5. Various versions were developed, with about 65 examples total being produced for the USAAF, U.S. Navy, and U.S. Coast Guard. The first two examples tested by the Navy were designated HO2S-1, while the remainder of the Navy/Coast Guard R-5 derivations were called the HO3S-1. A four-seat version known as the S-51 was produced for the civilian markets, and many of these were used by the U.S. armed forces as well.
