What is the official designation for the "Sea Stallion" helicopter?

The "Sea Stallion" helicopter is officially designated as the RH-53. This helicopter is a variant of the CH-53 Sea Stallion, which is primarily used by the United States Navy for mine countermeasures, utility transport, and vertical replenishment. The designation 'RH' specifically indicates that it is a recovery helicopter, designed for specific roles in maritime operations.

The other designations represent different helicopters: the V-22 refers to the Osprey tiltrotor aircraft, which combines features of both helical flight and vertical take-off, the H-57 does not correspond to a widely recognized helicopter model, and the SH-3 refers to the Sea King, which is distinct from the Sea Stallion with different capabilities and roles. The RH-53's specialized design and mission profile make it integral for naval operations, emphasizing the significance of its official designation.
