1477 (Norwegian) Flight) under the 210 Squadron of the British Royal Air Force, on 8 February 1942, by Captain Finn Lambrechts.

On 10 May 1943, 333 Squadron was formed from this flight[1] with de Havilland Mosquito IIs at RAF Leuchars and Consolidated PBY Catalina IBs at Woodhaven.

The Mosquitoes were operated on shipping reconnaissance flights along the Norwegian coast, whilst the Catalinas carried out anti-submarine patrols to the north of Scotland.

After the war, the squadron returned to Norway, being based at Fornebu, helping to rebuild the northern parts of the country, transporting people and equipment from the south to the north.

The Boeing P-8 Poseidon was introduced in the summer of 2023, and the squadron was subsequently relocated to Evenes Air Station, while the P-3 Orion was phased out.
