Aircraft Model / Manufacturer :
The Sikorsky S-58 was developed from the Sikorsky's UH-19 Chickasaw. The aircraft first flew on March 8, 1954. It was initially
designated HSS-1 Seabat (in its anti-submarine configuration) and HUS-1 Seahorse (in its utility transport configuration) under
the US Navy designation system. Under the US Army's system, also used by the fledgling US Air Force, the helicopter was designated H-34.
The US Army applied the name Choctaw to the helicopter. In 1962, under the new unified system, the Seabat was redesignated SH-34, the
Seahorse as the UH-34, and the Choctaw as the CH-34.
