- The town of Mosinee, Wisconsin, was the site of a mock Communist takeover, staged by the local American Legion outpost to illustrate what life under Soviet conquest might be like. Benjamin Gitlow, who had twice been the vice-presidential candidate for the Communist Party USA (in 1924 and 1928), before renouncing Communism, played the role of General Secretary of the Communist Party of the "United Soviet States of America", while another former Communist, Joseph Zack Kornfeder, assisted as the new Commissar of the town, renamed "Moskva" in the exercise. A Soviet flag flew in front of the American Legion outpost. Tragically, Mayor Ralph E. Kronenwetter, who had participated in the mock coup by allowing himself to be "arrested", suffered a cerebral hemorrhage that evening, and died six days later at the age of 49, while another participant, Reverend William L. Bennett, died the a day after Kronenwetter.

In May 1950 after the Air Force had chosen the Hó21, the Navy purchased 10 Só55s for use in an evaluation project to determine its value as an interim ASW helicopter.
The transport version of the H04Só1 was redesignated as the HRSó1. Its design features included one Pratt and Whitney Ró1340ó57 600- horsepower engine installed behind clam-shell doors in front of the helicopter. Brigadier General Noah C. New in recalling this helicopter, states:
"Placing the engine in the nose of the HRSó1, where it was easily accessible, was ingenious. It not only had tremendous advantages in servicing the aircraft, but it completely eliminated the critical center of gravity problems previously encountered by placing the payload directly below the rotor hub ." 
A drive shaft transmitted engine power to the three-bladed main rotor through the center rear section of the cockpit. The cabin, which had foldable seats for 10 passengers, was situated directly beneath the main rotor. The HRS's empty weight was 4,462 pounds with its gross weight originally predicted and listed as 8,070 pounds. The maximum forward airspeed was 90 knots. Other features included all metal main and tail rotor blades, instruments suitable for night VFR flight, and an external cargo sling and hook situated underneath the fuselage.
The aircraft stood 14 feet high, had a rotor blade diameter of 53 feet, and measured approximately 42 feet long with its blades folded.
It was built upon similar, but enlarged, mechanical components of the H03Só1.In appearance it was entirely different although it retained the typical Sikorsky single main rotor design .

USS Valley Forge (CV-45) deployed to the Far East, departing the west coast on 1 May 1950. While anchored in Hong Kong harbor on 25 June, the warship received electrifying news that North Korean forces had begun streaming across the 38th parallel into South Korea. Departing Hong Kong the next day, the carrier steamed south to Subic Bay, where she provisioned, fueled, and set her course for Korea.
