Although effectively only a stopgap model until more advanced helicopters were introduced, the HO5S was widely used in the Korean War by the USMC for observation, scouting and medevac. This example is displayed in the colours of VMO-6 with whom it served in Korea before being damaged and returned to the US after a brief detachment in Japan. Moving to VMO-1 at MCAS New River, NC it was civilianised as N8003E by 1963 and entered the Naval Aviation Museum around 1988

125519 served in the Korean War in 1952, assigned to VMO-2. In the photo it is temporarily on the museum floor with rotor blades removed while being rehung in a new location. On display in the museum main building.

USMC four-seat version of the Sikorsky S-52-3. 79 delivered to the Marines from 1952.

HO5S was the navy designation for the S-52 and 87 examples were procured for the Navy, Marines and Coast Guard. Although it was used in Korea as a scout, observation and medevac helicopter the HO5S was always something of a stopgap until the more advanced designs that superseded it came along. Now on display at the fantastic national Naval Aviation Museum.
