The Squadron was established as a detachment under the 210 Squadron of the British Royal Air Force, on 8 February 1942, by Captain Finn Lambrechts. The squadron was located in Woodhaven, Fife, Scotland. On 10 May 1943 333 squadron was formed from this flight with Mosquito Mk.IIs at RAF Leuchars and PBY-1b Catalinas 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. The squadron's Catalinas also operated in the 'Special Duties' role landing both personnel and supplies at points along the Norwegian coast. In September 1944 the Mosquito flight joined the Banff strike wing and acted in the Pathfinder role. However, on 30 May 1945 this flight was redesignated No. 334 Squadron RAF and No. 333 became a pure Catalina unit. 2nd from right On their first mission to Norway, the poet, and news-reporter Nordahl Grieg was with 333 Squadron to report from the flight. This was then a secret mission. After this mission, he wrote the poem Flagget. During the Second World War, the missions of 333 Squadron included dangerous search-and-destroy submarine missions, patrolling, and secret missions along the Norwegian coastline, behind the German defence lines. They landed and picked up agents, illegal radios, and transmitters. They also dropped Christmas presents to the Norwegian population, and did search and rescue missions.
Post-war
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 oil-activity, establishment of the Norwegian economic zone, and establishment of the coast-guard, created new demands on the squadron. They had to carry out surveillance of large sea areas, requiring new airplanes, the P-3 Orion. In the 1980s the squadron undertook search-and-destroy submarine missions along the coastline and in the fjords. Several times they have dropped sharp weapons against submarines that were illegal in Norwegian territory. In the 1990s, the Russian Northern Fleet was reduced by half, although it still has 67 operational submarines, and a large fleet of ships. Today the squadron regularly does various missions, including surveillance of military maritime operations, patrolling the economic zone, controlling fishing and resources, submarine searches, and search and rescue missions. They also take part in international missions and training. The squadron is the only one that has been active continuously since World War II, and is today a part of the 133 Air Wing.
