The Fairey Swordfish was a biplane torpedo bomber designed by the Fairey Aviation Company.
 Originating in the early 1930s, the Swordfish, nicknamed "Stringbag", was operated by the Fleet Air Arm of the Royal Navy, in addition to having been equipped by the Royal Air Force (RAF) alongside multiple overseas operators, including the Royal Canadian Air Force (RCAF) and the Royal Netherlands Navy.
 It was initially operated primarily as a fleet attack aircraft; during its later years, the Swordfish became increasingly used as an anti-submarine and training platform.
 The type was in frontline service throughout the Second World War, but it was already considered obsolescent at the outbreak of the conflict in 1939.
No. 76 Squadron was a squadron of the Royal Air Force.
 It was formed during World War I as a home defence fighter squadron and in its second incarnation during World War II flew as a bomber squadron, first as an operational training unit and later as an active bomber squadron.
 With the end of the war the squadron converted to the role of transport squadron, to be reactivated shortly in the bomber role during the 1950s.
 From 2007 to 2011, it was a training unit, equipped with the Short Tucano at RAF Linton-on-Ouse.
Western Air Command was the part of the Royal Canadian Air Force's Home War Establishment responsible for air operations on the Pacific coast of Canada during the Second World War.
 When Canada declared war against Germany in September 1939 the command consisted of only five squadrons.
 Four of them equipped with obsolete aircraft including a bomber squadron with aircraft from the Great War and there were no fighter aircraft at all for its only fighter squadron (113 Fighter Squadron was thus disbanded).
 With the Japanese threat after Pearl Harbor it grew rapidly and played a critical role in fighter and anti-submarine operations in Canadian and American waters during the Aleutian Islands Campaign.
 It was there that Squadron Leader K.A. Boomer of No. 111 Squadron shot down a Rufe fighter, the RCAF's only kill in the Pacific Theatre.
 On 7 July 1942 a Bristol Bolingbroke pressed home an attack on the Japanese Submarine Ro 32 the pilot F/Sgt.
 P.M.G. Thomas of No. 115 Squadron RCAF then led American Destroyers to sink the damaged submarine.
 By January 1943 Western Air Command had expanded to include many bomber, fighter and operational units under its control.
 By the end of the war the command would involve some twenty squadrons when the last units to join were added in 1943.
 These were the 163 Army Cooperation Squadron in March flying Bristol Bolingbrokes and Hawker Hurricanes, in May the 160 Bomber-Reconnaissance Squadron was added flying Cansos from Sea Island BC (before moving to Yarmouth NS in July) and the 166 Communication Squadron formed in September flying various types.
 In addition to the new squadrons, new aircraft types came on line replacing the command's remaining Supermarine Stranraers and Blackburn Sharks with Canso's and the Bolingbrokes and Beauforts with the Lockheed Ventura.
 Countless training missions and operational patrols bolstered the air activity over the coastal areas but there was not much action until RCAF Western Command was on the look out for General Kusaba's Fire Balloons that the Japanese called the Fūsen Bakudan Campaign.
 In February and March 1945, P-40 fighter pilots from 133 Squadron, Royal Canadian Air Force operating out of RCAF Patricia Bay (Victoria, British Columbia), intercepted and destroyed two fire balloons, On 21 February, Pilot Officer E. E. Maxwell While shot down a balloon, which landed on Sumas Mountain, in Washington State.
 On 10 March, Pilot Officer J. O. Patten destroyed a balloon near Saltspring Island, British Columbia.
 During another interception a Canso forced down a fire balloon which was examined at the army headquarters.
 Patrol activity was joined by the Operational Training Schools (OTS) operated by Number 4 Training Command of the BCATP.
 They were the No. 3 OTS flying the Canso and Catalina and No. 32 OTS with Ansons, Beauforts and Swordfish at Patricia Bay.
 In April, 1944 the No. 5 OTS Heavy Conversion unit stood up at Boundary Bay when 16 B-24 Liberators arrived fresh from American factories.
 By the end of September 1944 RCAF 5 O.T.U. had grown to sizeable force of some 87 aircraft including 38 B-24 Liberators, 35 B-25 Mitchells, 5 Bolingbrokes, 8 P-40 Kittyhawks and a single Norseman.
 With the end of the war in Europe these aircraft were joined by a number of Victory Aircraft Lancaster X bombers which were to be used to train the British Commonwealth's Very Long Range Bomber Tiger Force that would soon be sent to bomb the Japanese mainland from Okinawa.
 With the unconditional surrender of Japan the RCAF's Tiger Force bomber squadrons were disbanded before they flew overseas and the total draw down of the Western Air Command was suddenly undertaken.
 Within several months almost all the flying squadrons would be completely stood down.
Marshal of the Royal Air Force Charles Frederick Algernon Portal, 1st Viscount Portal of Hungerford, (21 May 1893 – 22 April 1971) was a senior Royal Air Force officer.
 He served as a bomber pilot in the First World War, and rose to become first a flight commander and then a squadron commander, flying light bombers on the Western Front.
 In the early stages of the Second World War he was commander-in-chief of Bomber Command.
 He was an advocate of strategic area bombing against German industrial areas, and viewed it as a war winning strategy.
 In October 1940 he was made Chief of the Air Staff, and remained in this post for the rest of the war.
 During his time as Chief he continuously supported the strategic bombing offensive against Germany, and advocated the formation of the Pathfinder Force, critical to improving the destructive force of Bomber Command.
 He fended off attempts by the Royal Navy to take command over RAF Coastal Command, and resisted attempts by the British Army to establish their own Army Air Arm.
 Portal retired from the RAF following the end of the war.
 He served as Controller of Production (Atomic Energy) at the Ministry of Supply for six years.
 Portal was then made chairman of British Aluminium.
 He was unsuccessful in fending off a hostile takeover of British Aluminum by Sir Ivan Stedeford's Tube Investments, in what was known as the "Aluminium War".
 Afterward he served as chairman of the British Aircraft Corporation.
Marshal of the Royal Air Force Arthur William Tedder, 1st Baron Tedder, {'1': ", '2': ", '3': ", '4': "} (11 July 1890 – 3 June 1967) was a senior Royal Air Force commander.
 He was a pilot and squadron commander in the Royal Flying Corps in the First World War and he went on to serve as a senior officer in the Royal Air Force during the inter-war years when he served in Turkey, Great Britain and the Far East.
 During the Second World War, as Air Officer Commanding RAF Middle East Command, Tedder directed air operations in the Mediterranean and North Africa, including the evacuation of Crete and "Operation Crusader" in North Africa.
 His bombing tactics became known as the "Tedder Carpet".
 Later in the war Tedder took command of Mediterranean Air Command and in that role was closely involved in the planning of the Allied invasion of Sicily and then the Allied invasion of Italy.
 When Operation Overlord—the invasion of France—came to be planned, Tedder was appointed Deputy Supreme Commander at Supreme Headquarters Allied Expeditionary Force under General Eisenhower.
 After the war he served as Chief of the Air Staff, in which role he advocated increased recruiting in the face of many airmen leaving the service, doubled the size of RAF Fighter Command and implemented arrangements for the Berlin Airlift in 1948.
 After the war he held senior positions in business and academia.
No. 22 Squadron of the Royal Air Force operated the Westland Sea King HAR.3 and HAR.3A at three stations in the southern United Kingdom.
 The squadron was originally formed in 1915 as an aerial reconnaissance unit of the Royal Flying Corps serving on the Western Front during First World War.
 Becoming part of the Royal Air Force on its formation in 1918, it was disbanded the following year as part of the post-First World War scaling back of the RAF.
 During the Second World War the squadron operated in the torpedo bomber role over the North Sea and then in the Mediterranean and the Far East.
 Between 1955 and 2015 the squadron provided military search and rescue over the United Kingdom.
The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain, Scandinavia, Germany, the Netherlands, Belgium, and France.
 An epeiric (or "shelf") sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north.
 It is more than 970 km long and 580 km wide, with an area of around 570000 km2 .
No. 6 (Bomber Reconnaissance) Squadron was a Royal Canadian Air Force squadron that was active during the Second World War.
 It was formed on 4 March 1936 at RCAF Station Trenton as a Torpedo Bomber squadron before moving to RCAF Station Jericho Beach in 1938.
 During the war it was primarily used in an anti-submarine role with Western Air Command, flying from Jericho Beach and Coal Harbour.
 The squadron flew the Blackburn Shark, Supermarine Stranraer, Consolidated Canso and Consolidated Catalina before disbanding on 7 August 1945.
No. 608 (North Riding) Squadron was an Auxiliary Air Force squadron of the Royal Air Force during the Second World War.
 It flew during its existence as a bomber, fighter and reconnaissance unit and was the only RAF squadron to be equipped with the unsuccessful Blackburn Botha torpedo bomber.
No. 25 (City of Perth) Squadron is a general reserve squadron of the Royal Australian Air Force (RAAF).
 It is based at RAAF Base Pearce in Perth, Western Australia, and forms part of the Combat Reserve Wing.
 The squadron was formed in early 1937 and until early 1939 was designated as "No. 23 Squadron".
 During World War II, it provided local air defence for the Perth region, before undertaking Army co-operation duties in 1943–44 and then converting to the heavy bomber role in 1945.
 In the heavy bomber role, the squadron took part in operations against Japanese targets in the Netherlands East Indies and supported Allied ground operations during the Borneo Campaign.
 Following the end of hostilities, No. 25 Squadron was disbanded in mid-1946 but was re-raised two years later as a Citizen Air Force unit based out of Pearce.
 From 1948 the squadron's reservists flew jet fighters to provide air defence over Western Australia, but the squadron ceased flying duties in 1960 and switched to the ground support role.
 In 1989, flying operations resumed as No. 25 Squadron assumed responsibility for jet introduction training and fleet support; this role ceased in 1998 and since then the squadron has been tasked with providing a pool of trained personnel to the Air Force.
