No. 78 Squadron was formed as part of the Royal Flying Corps on 1 November 1916 for home defence at Harrietsham and tasked with protecting the southern English coast. It was originally equipped with obsolescent B.E.2 two-seat biplanes, and the closely related B.E.12 single-seater. On the night of 25 September 1917 a Captain Bell of the squadron encountered a German Gotha and attacked it over RAF Joyce Green. John Rawlings, writing in Fighter Squadrons of the Royal Air Force (1969), stated that 'it was believed that he damaged it for one of the German raiders failed to return that night, being lost at sea.'[5] The squadron received Sopwith 1½ Strutters in late 1917, followed by Sopwith Camels in mid-1918. It arrived at Sutton's Farm, under the command of Major Cuthbert Rowden, in September 1917 and was there until December 1919, with a detachment at Biggin Hill. The squadron disbanded on 31 December 1919 following the Armistice.[6]
On the outbreak of the Second World War, the squadron was designated as a training squadron.[8] It moved to RAF Linton-on-Ouse on 15 October 1939, returning to Dishforth in July when it returned to front-line duties as a night bomber squadron. In February 1941, Whitleys from No. 78 Squadron and No. 51 Squadron, flying from Malta, were used to drop paratroops over southern Italy for Operation Colossus, the first British paratroop operation of the Second World War. In April 1941, the squadron moved to RAF Middleton St. George. In September, the squadron flew its first bombing raid against Berlin. It moved again, to RAF Croft, in October 1941.[7][9]
In early 1942, the squadron started to receive four-engine Handley Page Halifaxes to replace its Whitleys, with conversion being completed in March that year, and flying its first operation with the Halifax, against Ostend on 29 April 1942.[7] On the night of 30/31 May 1942, No. 78 Squadron contributed 22 Halifaxes to Operation Millennium, the first "1,000 bomber" raid against Cologne.[7]
The squadron moved back to Middleton St. George in June 1942 and to Linton-on-Ouse in September 1942.[7] In June 1943, the squadron moved to RAF Breighton to free up Linton-on Ouse for the Canadian bomber force of No. 6 Group.[9]
In January 1944, the squadron replaced its Merlin-powered Halifax B.IIs with Halifax B.IIIs, powered by Bristol Herculesradial engines which gave greater performance. The squadron continued in the bomber mission until the end of the war in Europe, both against German cities and in direct support of allied ground forces during and after the invasion of France in June 1944. In total, the squadron had dropped 17,000 tonnes of bombs and mines during 6,337 operational sorties, losing 182 aircraft but claiming 28 enemy fighters shot down.[10]
Transport operations (1945–1971)
In May 1945, the squadron was transferred into Transport Command, re-equipping with Douglas Dakota Mk.IVs in July–August 1945 and moving to Cairo in September, flying transport operations around the Middle East and Air-Sea Rescue patrols over the Eastern Mediterranean.[11] It remained active in the post-war period as a transport squadron, converting to Vickers Valetta C.1s in April 1950, before being disbanded at RAF Fayid in Egypt on 30 September 1954.[9][11]
From 1988, No. 78 Squadron was based in the Falkland Islands. The squadron operated Westland Sea King HAR.3 and Chinook HC2s.[15]
In December 2007, No. 78 Squadron reverted to its previous identity of No. 1564 Flight and a new No. 78 Squadron stood-up at RAF Benson as part of the Joint Helicopter Command on 28 January 2008,[16] flying the AgustaWestland Merlin HC3 and six new Merlin HC3A helicopters purchased from Denmark. The squadron shared the total fleet of twenty eight RAF Merlin helicopters with No. 28 (AC) Squadron, also based at RAF Benson.[17]
Following the transfer of the squadron's Merlins to 846 Naval Air Squadron of the Fleet Air Arm,[18] No. 78 Squadron was disbanded on 30 September 2014.[19]
On 24 March 2020, the squadron was awarded a battle honour, recognising its role in the War in Iraq between 2003 and 2011.[20]
Military air traffic control (2021 – present)
The squadron number plate was allocated to RAF (Unit) Swanwick during early 2021.[4] The unit is embedded in the civilian London Area Control Centre, based at Swanwick in Hampshire and provides a military air traffic control service across the UK.[21]
