What is the common designation for the multi-mission rotary helicopter MH-60R/S?

The MH-60R/S helicopters are commonly designated as SEAHAWKS. This name reflects their versatility and multi-mission capabilities, which include anti-submarine warfare, anti-surface warfare, and search and rescue operations, among other roles. The SEAHAWK is a vital platform for the U.S. Navy, enabling them to perform various missions effectively in maritime environments.

The other options, while they may represent different aircraft or missions, do not apply to the MH-60R/S helicopters. The Viper generally refers to different military helicopters, particularly in reference to the AH-1Z Viper attack helicopter. Osprey refers to the V-22 Osprey, a tilt-rotor aircraft used for transport and special operations, and SEADUCK does not correspond to a widely recognized military aircraft designation. This reinforces the significance of the SEAHAWK designation in conjunction with the specific capabilities of the MH-60R/S helicopters.
