Question: During the Second World War, the No. 22 Squadron of the Royal Air Force operated in the torpedo bomber role over this body of water located between Great Britain, Scandinavia, Germany, the Netherlands, Belgium, and France?

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. <SEP>  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. 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.  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. <SEP>  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. The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain, Scandinavia, Germany, the Netherlands, Belgium, and France.  It is more than 970 km long and 580 km wide, with an area of around 570000 km2 . <SEP> 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.
