No. 4 Squadron RAF

No. 4 Squadron formed at Farnborough in 1912 as part of the Royal Flying Corps. Operating a mixture of aircraft including early versions of the Royal Aircraft Factory B.E.2 and Breguet biplane, the squadron quickly moved to Netheravon where it remained until the outbreak of the First World War. The more useful aircraft in its inventory were sent to France under the command of Major G. H. Rayleigh on 16 August 1914, to carry out reconnaissance in support of the British Expeditionary Force. On 19 August Lieutenant G. W. Mapplebeck flew the squadron's first mission over France, a reconnaissance flight searching for German cavalry in the vicinity of Gembloux, Belgium. Other aircraft remained in England to carry out anti-Zeppelin patrols.Ashworth 1989, p. 32.Yoxall 1950, pp. 255–256.

The contingent in France was reinforced on 20 September by the personnel who had remained behind in England, forming C Flight, equipped with the Maurice Farman MF.11 Shorthorn. It concentrated on the reconnaissance role, standardising on the B.E.2 in 1916. In the Battle of the Somme, the squadron flew contact patrols keeping track of the position of advancing troops at low level, in addition to more regular reconnaissance and artillery spotting missions. It re-equipped with the Royal Aircraft Factory R.E.8 in June 1917, in time to take part in the Battle of Messines and the Battle of Passchendaele. During this period William Robinson Clarke, the first black pilot to serve for Britain, flew for the squadron. It remained equipped with the R.E.8 until the Armistice with Germany on 11 November 1918 ended the fighting.Yoxall 1950, pp. 256–258. The squadron returned to the United Kingdom in February 1919 as a cadre.{{cite web |url=https://www.nationalcoldwarexhibition.org/research/squadrons/4/ |title=No.4 Squadron |website=Royal Air Force Museum |access-date=15 May 2023}}

No. 4 Squadron returned to full strength on 30 April 1920 at Farnborough, equipped with Bristol F.2 Fighters. Part of the squadron moved to Aldergrove near Belfast in November 1920 as a result of the Irish War of Independence, moving to Baldonnel Aerodrome near Dublin in May 1921, before rejoining the rest of the squadron at Farnborough in January 1922.Yoxall 1950, p. 258. The squadron deployed on Royal Navy aircraft carriers when they sailed to Turkey on HMS Ark Royal and Argus during the Chanak crisis in August 1922, returning to Farnborough in September 1923. When the 1926 General Strike broke out, the squadron's aircraft were used to patrol railway lines to deter feared sabotage.Yoxall 1950, pp. 258–259.

In October 1929, the elderly Bristol Fighters were replaced with new Armstrong Whitworth Atlas, purpose-designed for the squadron's army co-operation role. These in turn were replaced by Hawker Audaxes in December 1931.Yoxall 1950, p. 259.Halley 1980, p. 22. In February 1937, it moved from Farnborough to RAF Odiham, soon re-equipping with the Hawker Hector, a more powerful derivative of the Audax. In January 1939, it discarded its Hector biplanes in favour of the new monoplane Westland Lysander.Halley 1980, pp. 22–23.

Shortly after the outbreak of the Second World War in 1939, the squadron moved to France as part of the British Expeditionary Force. Following Germany's invasion of France and the Low Countries on 10 May 1940, the squadron was frequently forced to change bases by the approach of the advancing German armies, being withdrawn to the UK on 24 May. Losses had been heavy, with 18 aircrew killed, while 60% of the groundcrew were lost. It continued in the coastal patrol and air-sea rescue role while training for its main army co-operation role after returning to the UK.

In 1942, the squadron changed its mission from the army co-operation role, where it would operate fairly low-performance aircraft from airstrips close to the front-line, to that of fighter-reconnaissance, receiving the more modern Curtiss Tomahawk and North American Mustang, with the latter soon replacing Tomahawk, flying low-level attack and reconnaissance flights against targets on the continent.

In August 1943, it joined the Second Tactical Air Force in support of the planned invasion of Europe, changing to the pure reconnaissance mission in January, and replacing its Mustangs with the Mosquito PR.XVI and Spitfire PR.XI. It discarded its Mosquitoes in June, moved to France in August, and briefly supplemented its Spitfires with a few Hawker Typhoons for low-level reconnaissance. It retained its Spitfires at VE Day, moving to Celle in Germany to carry out survey operations in support of the British Army of Occupation until it was disbanded on 31 August 1945.Yoxall 1950, pp. 261–262.

The squadron reformed the next day by renumbering No. 605 Squadron, a light bomber squadron equipped with Mosquitoes based at Volkel in the Netherlands. It re-equipped with de Havilland Vampire fighter-bombers in July 1950, replacing them with North American Sabres in October 1953. The Sabres were discarded in favour of the Hawker Hunter in July 1955, retaining these until the squadron disbanded at RAF Jever on 31 December 1960.

Again, the squadron did not remain dormant for long, as it reformed on 1 January 1961 by renumbering No. 79 Squadron, flying the Hunter FR.10 in the low-level reconnaissance role. It re-equipped with the Hawker-Siddeley Harrier in 1970, first flying from RAF Wildenrath in West Germany. It moved on to RAF Gütersloh in 1977.File:RAF British Aerospace Harrier GR9 Lofting-2.jpg of No. 4 Squadron wearing special tail marking during 2010|left]]The squadron operated the Harrier until the final withdrawal of the type, receiving numerous upgrades and new versions over the years. In April 1999, the squadron left Germany to move to RAF Cottesmore.{{Cite web|url=http://www.raf.mod.uk/organisation/4squadron.cfm|title=4 Squadron|work=www.raf.mod.uk|publisher=Royal Air Force|access-date=4 May 2010|archive-url=https://web.archive.org/web/20120404142703/http://www.raf.mod.uk/organisation/4squadron.cfm|archive-date=4 April 2012|url-status=dead}}

On 31 March 2010, the squadron disbanded and reformed as No. 4 (Reserve) Squadron at RAF Wittering, taking over from No. 20 (R) Squadron as the Harrier Operational Conversion Unit.{{Cite web|url=http://www.airinternational.com/view_news.asp?ID=1855|title=IV into 20 goes once|date=2010-04-01|work=Air International|access-date=4 May 2010|url-status=dead |archive-url=https://web.archive.org/web/20110617052527/http://www.airinternational.com/view_news.asp?ID=1855|archive-date=17 June 2011}} As a result of the 2010 Strategic Defence and Security Review, the squadron disbanded in January 2011,{{Cite web|url=http://www.rafweb.org/Sqn001-5.htm|archiveurl=https://web.archive.org/web/20140901003701/http://www.rafweb.org/Sqn001-5.htm|url-status=dead|title=Air of Authority: Squadron Histories 1–5|archivedate=1 September 2014}} only to reform on 24 November 2011, when No. 19 (R) Squadron, operating the BAE Hawk T2 from RAF Valley in the tactical weapons training role, was renumbered.

In March 2020, the squadron was awarded the right to emblazon a battle honour on its squadron standard, recognising its role in Bosnia during 1995.{{Cite web|url=https://www.raf.mod.uk/news/articles/raf-squadrons-receive-battle-honours-from-her-majesty-the-queen/|title=RAF Squadrons Receive Battle Honours from Her Majesty The Queen|date=24 March 2020|website=Royal Air Force|language=en-gb|access-date=25 March 2020}}

Approved by King Edward VIII in May 1936, the squadron's badge features a sun in splendour divided per bend by a flash of lightning. The red and black segmented sun suggests round-the-clock operations (day and night), while the lightning flash is a reference to the unit's early use of wireless telephony for artillery co-operation.{{Cite web |date=17 December 2003 |title=History of No. IV Squadron |url=http://www.raf.mod.uk/squadrons/h4.html |url-status=dead |archive-url=https://web.archive.org/web/20040126024320/http://www.raf.mod.uk/squadrons/h4.html |archive-date=26 January 2004 |access-date=28 February 2025 |website=Royal Air Force}}
