Description: Naval Station Mayport (IATA: NRB, ICAO: KNRB, FAA LID: NRB) is a major U.S. Navy base adjacent to Jacksonville in coastal Duval County, Florida. It contains a military airfield (Admiral David L. McDonald Field) with one asphalt paved runway (5/23) measuring 8,001 x 200 ft. (2,439 x 61 m).
The Sikorsky SH-60/MH-60 Seahawk (or Sea Hawk) is a twin turboshaft engine, multi-mission United States Navy helicopter based on the airframe of the United States Army UH-60 Black Hawk and a member of the Sikorsky S-70 family. The most significant modification is a hinged tail to reduce its footprint aboard ships.
The U.S. Navy uses the H-60 airframe under the model designations SH-60B, SH-60F, HH-60H, MH-60R, and MH-60S. Able to deploy aboard any air-capable frigate, destroyer, cruiser, fast combat support ship, amphibious assault ship, or aircraft carrier, the Seahawk can handle antisubmarine warfare (ASW), undersea warfare (USW), anti-surface warfare (ASUW), naval special warfare (NSW) insertion, search and rescue (SAR), combat search and rescue (CSAR), vertical replenishment (VERTREP), and medical evacuation (MEDEVAC). All Navy H-60s carry a rescue hoist for SAR/CSAR missions.
