No. 231 Squadron RAF was a unit of the Royal Air Force formed during the final months of the First World War and reformed for operations in the Second World War. Active in anti-submarine warfare and air transport roles, the squadron operated a succession of maritime and transport aircraft from bases across the United Kingdom, the Mediterranean Sea, and Southeast Asia Command. Its operations connected it with major wartime organisations and theatres including RAF Coastal Command, RAF Transport Command, Allied invasion of Sicily, and the Burma Campaign.
Formed in 1918 at Walmer as a training squadron during the late First World War, the unit was disbanded in 1919 following the Armistice of 11 November 1918. Reformed in 1939 at Blackpool as No. 231 Squadron, it joined RAF Coastal Command for anti-submarine warfare and convoy patrols using aircraft such as the Vickers Wellington and Short Sunderland. During the Battle of the Atlantic, the squadron cooperated with Royal Navy escorts, Convoy SC operations, and Admiralty direction to counter U-boat threats. In 1943 elements were transferred to the Mediterranean Theatre to support the Allied invasion of Sicily and operations from Malta and Pantelleria. Later the squadron converted to long-range patrols and transport sorties supporting South East Asia Command operations during the Burma Campaign, linking with units such as No. 267 Squadron RAF and No. 355 Squadron RAF. Postwar reductions saw the squadron disbanded in 1945 during the drawdown overseen by Air Ministry policy.
Throughout its existence the squadron flew a diverse mix of aircraft reflecting shifts between maritime and transport roles. Types operated included: Airco DH.6 (training era), Avro Anson (maritime reconnaissance), Vickers Wellington (maritime patrol), Short Sunderland (flying boat patrol), Consolidated Catalina (patrol and air-sea rescue), and transport types aligned with Douglas Dakota operations during late-war airlift tasks. These aircraft connected the squadron operationally to manufacturers such as Vickers-Armstrongs and Short Brothers, and to logistical networks involving RAF Maintenance Command and Ministry of Aircraft Production.
The squadron operated from numerous UK and overseas stations reflecting strategic priorities. UK bases included Blackpool, Milford Haven, and St Eval under RAF Coastal Command control. Mediterranean deployments placed elements at Malta and Pantelleria during Operation Husky, while later stages saw postings in Ceylon and India supporting South East Asia Command logistics. These deployments brought the squadron into operational interaction with commands such as RAF Middle East Command, Mediterranean Air Command, and Allied naval formations including Force H.
Commanding officers during wartime included RAF commanders drawn from the Royal Air Force Volunteer Reserve and regular RAF lists, many with prior postings to squadrons such as No. 201 Squadron RAF, No. 209 Squadron RAF, and No. 210 Squadron RAF. Officers often attended staff courses at RAF Staff College, Andover and coordinated operations with senior figures in RAF Coastal Command like Air Chief Marshal Sir Philip Joubert de la Ferté and theatre commanders involved in Mediterranean Theatre of Operations. Command appointments reflected personnel interchange with units in Transport Command and joint planning with Royal Navy Flag Officers.
The squadron earned honours associated with major campaigns and theatres where it operated, including honours tied to the Atlantic Ocean, the Mediterranean Sea, and the Burma Campaign. Specific engagements encompassed operations during the Battle of the Atlantic, convoy escort and anti-submarine successions, and support for Operation Husky during the Allied invasion of Sicily. These honours align with broader recognitions awarded across RAF Coastal Command and RAF Transport Command for contribution to Allied maritime and air logistics.
Insignia and markings reflected maritime patrol heritage with squadron codes applied under Air Ministry insignia regulations; typical serials conformed to patterns used by units operating Short Sunderland and Consolidated Catalina flying boats. Traditions included commemorations tied to significant events such as the squadron's World War I formation near Dover and World War II operations from Malta and Ceylon, observed alongside wider RAF observances at Churchill College, Cambridge archives and memorials like the Battle of Britain Memorial. The squadron's legacy is preserved in collections of the Imperial War Museum and regimental histories held by RAF Museum.
