RAF Mona

RAF Mona is a Royal Air Force station located near Bodffordd on the island of Anglesey, Wales. It primarily serves as a relief landing ground for RAF Valley. The site's aviation history began during the First World War, when it was established as Royal Naval Air Station (RNAS) Anglesey in 1915. Operating SS class airships, the station conducted anti-submarine patrols and escorted ships in the Irish Sea. Experimental work, including the use of hydrophones and phosphorus for smoke screens, was also carried out. After the First World War, the site was sold and used as an isolation hospital.

During the Second World War, the site was requisitioned in 1941 and reopened as an airfield, initially named RAF Heneglwys before being renamed RAF Mona. Concrete runways were laid in 1943. It was used by No. 3 Air Gunnery School, equipped with Blackburn Botha, Fairey Battle, and Miles Martinet aircraft, later replaced by Avro Ansons. It also hosted No. 5 (Pilots) Advanced Flying Unit and No. 8 (Observers) Advanced Flying Unit for training. The airfield was placed on care and maintenance at the end of the war.

RAF Mona reopened in 1951 as a relief landing ground for RAF Valley, a role it maintains today. It supports circuit practice for BAE Systems Hawk T.2 aircraft from RAF Valley. In addition to its military operations, the base also hosts Mona Flying Club and 2474 (Cefni) Squadron Air Training Corps.
