Kamenny Ruchey (also Mongokhto, Alekseyevka, and Mongohto) (Russian: Монгохто, Каменный Ручей) (ICAO: UHKG) is an air base in Russia located 29 km north of Sovetskaya Gavan. Located just north of Vanino, this is a major military airfield that has 63 hardened areas. The airfield is designated by CAICA as Kamenny Ruchey, but Russian topographic maps indicate the nearby settlement northeast of the airfield is Mongokhto, which is also synonymous with the military base.
