Military unit
Number 111 (Fighter) Squadron, also known as No. CXI (F) Squadron and nicknamed Treble One, was a squadron of the Royal Air Force. It was formed in 1917 in the Middle East as No. 111 Squadron of the Royal Flying Corps during the reorganisation of the Egyptian Expeditionary Force after GeneralEdmund Allenby took command during the Sinai and Palestine Campaign. The squadron remained in the Middle East after the end of the First World War until 1920 when it was renumbered as No. 14 Squadron.
Operating the Hawker Hunter, No. 111 Squadron provided an aerobatic display team – the Black Arrows. It also performed aerobatics when it re-equipped with the Lightning interceptor. The Squadron moved to Scotland in 1975, shortly after changing to flying Phantoms. In 1990 the squadron began flying the air defence variant of the Panavia Tornado. It operated the Panavia Tornado F3 in air defence from RAF Leuchars, Scotland until March 2011, when the squadron was disbanded, ending Tornado F3 service in the RAF.[3]
History
First World War
No. 111 Squadron of the Royal Flying Corps was formed at Deir el-Balah, Palestine, on 1 August 1917, under the command of Major Shekleton, with a mixed bag of single seat fighters as the first dedicated fighter squadron in the region.[4] Its mission was to restrict enemy reconnaissance flights and challenge the German fighter presence over Suez. It was reinforced by Bristol F.2 Fighters in September, one of these claiming the first aerial victory for No. 111 Squadron on 8 October.[5] The squadron began to receive the Royal Aircraft Factory S.E.5a in October 1917. The same month also saw a change of command with Major Shekleton was replaced by Major Strent, after Shekleton became Commander of the 40th (Army) Wing.[4] By December, No. 111 Squadron was based at Julis.[4]
Treble One moved to Egypt after the War ended and then to Ramla in Palestine on 6 February 1919, re-equipping with the Bristol Fighter. On 1 February 1920, the squadron renumbered to No. 14 Squadron.[7] On 1 October 1923, No. 111 Squadron reformed at RAF Duxford, equipped with a single flight of six Gloster Grebe fighters, the first Grebes to enter service with the RAF.[7][9] These were supplemented by a second flight of First World War-vintage Sopwith Snipes in April 1924, and by a third flight of Armstrong Whitworth Siskins in June 1924, completely equipping itself with Siskins in January 1925.[10] The squadron, tasked with defending London, replaced its Siskins with Bristol Bulldogs in January–February 1931, with its Siskins being passed on to No. 19 Squadron.[11] The squadron moved to RAF Northolt in July 1934[12] and re-equipped with Gloster Gauntlets in May–June 1936. The squadron became the first Hawker Hurricane squadron in January 1938.[11]
Second World War
1939–1940
Still based at RAF Northolt at the outbreak of war, No. 111 (Fighter) Squadron relocated to RAF Acklington, Northumberland, in October 1939.[13] The squadron scored its first victory on 29 November, when Sqn. Ldr. Broadhurst shot down a Heinkel He 111.[4]Treble One moved even further north to RAF Drem, East Lothian, in December 1939 in order to provide cover for the Royal Navy at Scapa Flow.[13] By May 1940, No. 111 (F) Squadron had returned south to RAF Northolt due to the German invasion of France.[4] On 16 May, a flight from No. 111 (F) Squadron joined a flight from No. 253 Squadron to form a joint unit, with one half deploying to France and the other remaining in Britain.[13]Treble One flew defensive flights during the Dunkirk evacuation.[14]
No. 111 (Fighter) Squadron played a role in the Battle of Britain while based at RAF Croydon, pioneering dangerous head-on attacks against the Luftwaffe bomber streams. However, after suffering heavy losses in August 1940, the unit was rotated north in September to RAF Drem.[13] Claims included 47 aircraft shot down for 18 Hurricanes lost.
1941–1945
The squadron replaced its Hurricanes with Supermarine Spitfires in April 1941. In November, Treble One again relocated to RAF Gibraltar for support of Operation Torch, the invasion of North Africa. Under the command of Squadron Leader George Hill it moved to Malta in June 1943 to support Operation Husky, the invasion of Sicily. No. 111 (F) Squadron moved through Italy with the advancing Allied ground forces and remained there until the end of the war, after which it moved to Austria. The squadron disbanded in May 1947. 269 aircraft were claimed shot down, making the squadron one of the top RAF scorers for the war.
The squadron received the all-weather English Electric Lightning fighter in 1962 which it operated for 12 years. In 1965, under Squadron Leader George Black (later AVM) and fully equipped with Lightning F3's, it was chosen to provide a combined display with the Red Arrows for the Paris Air Show in June of that year. During the 2 to 3 months workup of the Diamond Nine formation plus a solo aerobatics Lightning, the squadron fielded 10 aircraft per day, a remarkable achievement for what was a somewhat difficult aircraft to service. In 1974, the squadron moved from RAF Wattisham after almost 18 years and re-equipped with the McDonnell Douglas Phantom FGR.2 at RAF Coningsby, before moving north to RAF Leuchars on 3 November 1975.
Tornado F.3 (1990–2011)
The squadron began to re-equip with the Tornado F.3 in 1990.[14] Throughout its time at Leuchars the No. 111 (F) Squadron was tasked with the maintenance of Quick Reaction Alert, which involves keeping aircraft at a high state of readiness to intercept, identify and, should it be necessary, destroy hostile aircraft approaching UK airspace. The squadron was involved in Operation Deny Flight and Operation Deliberate Force over Bosnia, Operations Bolton and Resinate in the Middle East and regularly participated in major Air Defence exercises, both in the UK and abroad.
Following the disbandment of No. 43 Squadron in July 2009, Treble One was the sole RAF Tornado F3 unit.[16][17] The squadron disbanded at RAF Leuchars on 22 March 2011.[3]
