Naval Air Facility Atsugi

Naval Air Facility Atsugi (厚木海軍飛行場, Atsugi Kaigun-hikōjō) (IATA: NJA, ICAO: RJTA) is a naval air base located in the cities of Yamato and Ayase in Kanagawa Prefecture, Japan. It is the largest United States Navy air base in the Pacific Ocean and houses the squadrons of Carrier Air Wing 5, which deploys with the aircraft carrier USS Ronald Reagan (CVN-76). Service members stationed at Atsugi also work in conjunction with the Kamiseya Naval Radio Receiving Facility.

CVW-5 shares the base with the Headquarters Fleet Air Force and Fleet Air Wing 4, Japan Maritime Self-Defense Force. NAF Atsugi is also home to Helicopter Maritime Strike Squadron 51 (HSM-51), which provides detachments of SH-60B LAMPS Mk III helicopters and MH-60R helicopters to forward deployed U.S. Navy guided missile cruisers, guided missile destroyers and frigates homeported at nearby Naval Base Yokosuka.

Despite its name, the base is 4 nautical miles (7.4 km; 4.6 mi) east northeast from the city of Atsugi, and is not adjacent to the city.
