It was also the first helicopter to be procured under the US Navy's new weapon system concept, under which Sikorsky was responsible not only for the design and production of the airframe itself but all of the major onboard systems, such as the sonar, navigational equipment, electronic devices, and support equipment.
Tamén foi o primeiro helicóptero adquirido baixo o novo concepto de sistema de armas da Armada, baixo o cal Sikorsky era responsable non só do deseño e fabricación da célula, senón tamén de todos os principais sistemas a bordo do aparello, como o sónar, o equipo de navegación, os dispositivos electrónicos e o equipamento de apoio.
