No.404 Squadron, RCAF, was a long range fighter and anti shipping squadron that served with RAF Coastal Command from 1941-45.

No.404 Squadron was formed on 15 April 1941 as a long range fighter squadron within Coastal Command. It was equipped with the Blenheim IVF, which it took to Scotland in June 1941.

The squadron was used to escort convoys and to fly long range reconnaissance missions. In December 1941 it supported the raid on the Lofoten Islands. It was also used to try and intercept Condors flying north of Scotland on their way between Norway and the North Atlantic.

In September 1942 the squadron began to convert to the Beaufighter.

In January 1943 the squadron moved to Devon, and began to fly patrols over the Bay of Biscay as part of Coastal Command's campaign against the U-boats.

In April 1943 the squadron returned to the north of Scotland. As well as convoy patrols, the squadron was also used to provide long range fighter escorts for strike squadrons operating along the coast of Norway.

In May 1944 the squadron moved south, and in June it was used to protect the western flank of the shipping lanes from southern England to France. The squadron took part in an attack on three German destroyers spotted south of Brest, although couldn't stop them reaching the port. However two days later, when they attempted to leave Brest, they were attacked by surface ships, and only one survived.

In July 1944 the squadron moved to East Anglia and was used to attack shipping along the Dutch coast.

In September 1944 the squadron returned to Scotland and operations off the Norwegian coast. It was part of the Banff Wing, one of the most effective anti-shipping units of the war and the largest users of the Mosquito in the anti-shipping role.

The squadron was disbanded on 25 May 1945.
