No. 27 Squadron RAF

A Martinsyde Elephant in 1917.

27 Squadron formed at Hounslow Heath Aerodrome on 5 November 1915 (1915-11-05), soon being equipped with Martinsyde Elephant fighter aircraft, hence the use of an elephant for the squadron badge.[2] It transferred to France early in 1916, but although initially using their aircraft as escort fighters, by the time the Battle of the Somme began, it was clear that the Elephant was unsuitable as a fighter, and the Squadron switched to a bomber-reconnaissance role, taking advantage of the Martinsyde's good range and load carrying capacity,carrying out its first bombing mission on 1 July 1916.[3]

It re-equipped with Airco DH.4s, which carried twice the bombload of the Martinsyde at greater speed and height, while carrying a gunner to defend against enemy fighters, from between September and November 1917, flying missions in support of the British offensive at Cambrai, and low level missions against the attacking German troops during the Spring Offensive of 1918. It started to receive DH.9 bombers in July 1918, but as these proved to be inferior to the DH.4, managed to keep some of its DH.4s until the end of the war. The squadron was disbanded on 22 January 1920.[4]

On 1 April 1920, No. 27 was reformed by re-numbering No. 99 Squadron RAF then in India, flying Airco DH.9A light bombers from Risalpur over the North-West Frontier. These aircraft were eventually replaced by Westland Wapitis in 1928, when the squadron moved to Kohat.[5] In December 1928, Flying Officer Tusk and Leading Aircraftman Donaldson (both of 27 Squadron), flew the first mission of the Kabul Airlift. Strictly a reconnaissance flight to ascertain the situation of the British Legation in Kabul during a civil war, they were shot at by local tribesmen and forced to land at a nearby airstrip. After this they managed to dash across no-man's land and arrived at the legation to set up communications with their home base of Risalpur.[6]

In October 1939, the squadron became a flying training school, operating de Havilland Tiger Moth and Hawker Hart biplanes as well as Wapitis, but was re-equipped with Bristol Blenheim bombers by the end of 1940.[7][2]

It was based in Malaya when the Japanese invaded, using its Blenheims as long range fighters, but quickly received heavy losses and was effectively wiped out as a fighting unit by early 1942.[5][7]

A new No. 27 Squadron was formed in India on 19 September 1942, receiving Bristol Beaufighters, using them for ground-attack missions over Burma and anti-shipping strikes.[8] In April 1943, the squadron received a number of de Havilland Mosquitoes for evaluation, and a flight was re-equipped with Mosquitoes in December that year.[9] The glue-and-plywood construction of the otherwise excellent Mosquito proved to be less than optimal for tropical Burma, and the operations where plagued by technical problems.[10] They eventually relinquished the Mosquitoes to No. 680 Squadron RAF, retaining the Beaufighters and continuing the Squadron's diet of ground attack and anti-shipping strikes, switching to air-jungle rescue in April 1945.[2][9]

Following the Japanese surrender, it was deployed to Batavia during the Indonesian War of Independence, being disbanded on 1 February 1946.[2][9]

On 24 November 1947, the squadron reformed at RAF Oakington as a Transport unit equipped with Douglas Dakota transports. It flew both routine scheduled transport routes and trained in glider towing, and took part in the Berlin Airlift in 1948–49. It was disbanded on 10 November 1950.[9] On 15 June 1953, No. 27 Squadron reformed at RAF Scampton as part of RAF Bomber Command, with Canberra bombers. It took part in the Suez Crisis in 1956, and was disbanded at RAF Waddington on 31 December 1957.[9]

In April 1961, the squadron reformed at RAF Scampton as the first squadron to be equipped with the Avro Vulcan B2 V bomber[11] and formed part of the UK nuclear deterrent strike force. The squadron's Vulcans were equipped with the Blue Steel one megaton stand-off bomb until 1969 when their eight aircraft were each re-equipped with a WE.177B laydown bomb[12] of 450 kt yield. The squadron's role assigned to SACEUR in a low-level penetration role was tactical support for ground forces resisting a Soviet land attack into Western Europe by striking targets assigned by SACEUR, beyond the forward edge of the battlefield, and deep into enemy-held areas.[13] By the end of 1971 the squadron had relinquished its nuclear delivery role, and stood down until in December 1973 it was reformed at RAF Scampton with the Vulcan B2 to operate in the Maritime Radar Reconnaissance (MRR) role assigned to SACLANT.[2]

From 1973 to 1982 the squadron performed the duties of 'Strategic Reconnaissance' with onboard equipment to monitor the fall-out from air and ground-based nuclear tests being performed by emerging nuclear powers in the Indian sub-continent and SE Asia. The squadron's Vulcan B2s were modified (and re-designated as "Vulcan B.2 (MRR)") to carry underwing 'sniffer' and collection equipment to detect and collect samples of airborne contamination for later analysis at the Atomic Weapons Research Establishment (AWRE) at Aldermaston. The samples were collected by flying through the high altitude dust cloud of a ground-based test or the downwind contamination of the upper atmosphere after an air burst. The squadron disbanded again at Scampton in 1982.[2]

The squadron reformed again at RAF Marham in 1983 with twelve Tornado GR1 aircraft and eighteen WE.177 nuclear bombs, and once again assigned to SACEUR in 1984,[14] the squadron's role was low-level penetration tactical support for ground forces resisting a Soviet land attack into Western Europe by striking targets beyond the forward edge of the battlefield. The squadron's allocation of eighteen WE.177 weapons was because of the greater carrying capacity of the Tornado, which could carry two weapons. The apparent mismatch between twelve Tornado aircraft and eighteen nuclear weapons was because RAF staff planners expected up to one third attrition of aircraft in the conventional phase, with sufficient aircraft held back in reserve to deliver the squadron's full stock of nuclear weapons if the conflict escalated to the use of tactical nuclear weapons. In September 1993, the squadron's Tornado aircraft and personnel moved to RAF Lossiemouth and took on the number plate of No. 12 Squadron which had recently disbanded at RAF Marham.[15]

The No. 27 Squadron number plate was transferred to RAF Odiham and became No. 27 (Reserve) Squadron, the Chinook/Puma Operational Conversion Unit,[16] formerly No. 240 Operational Conversion Unit RAF (OCU). It regained full squadron status in January 1998 equipped with Chinooks only. In 2002 the squadron's Chinooks saw service in Afghanistan as they transported Royal Marines from 3 Commando Brigade for Operation Jacana.[17]

The squadron also served in a transport role during the 2003 invasion of Iraq and was stationed at Basra as part of No. 1310 Flight RAF, supporting Operation Telic.[18] In July 2006, 3 Chinook helicopters of No.27 Squadron deployed to RAF Akrotiri in Cyprus to evacuate British citizens from Lebanon.[19] It deployed to Afghanistan for Operation Herrick in 2011.[20]

In March 2020, the squadron was awarded the right to emblazon a battle honour on its squadron standard, recognising its role in the War in Afghanistan between 2001 and 2014.[21]
