No. 107 Squadron RAF

No. 107 Squadron RAF was a Royal Flying Corps bomber unit formed during the First World War. It was reformed in the Royal Air Force during the Second World War and was operational during the Cold War on Thor Intermediate Range Ballistic Missiles.

Formation and the First World War
Though already formed at Catterick, Salisbury as a day bomber unit on 8 October 1917 ), no. 107 squadron was not equipped with aircraft till 15 May 1918, when it received Airco DH.9s, which it took to the Western Front on 3 June of that year. The squadron became at first part of the 13th wing of the 3rd brigade, working up to operational status. Thereafter it was transferred to the 51st wing of the 9th brigade and it began operations from Drionville. Its main targets were enemy airfields, base areas and communication lines, which it continued to attack until the Armistice. The squadron's most successful raid was made on Saponay on 21 July 1918, where a large ammunition dump was hit. From the squadron's airfield, 20 miles away at Chailly, the reflection of the explosions and fire could be seen going on all the evening and throughout the night. Another notable raid was that made on the Aulnoye railway station and junction on 1 October 1918. Returning to Hounslow Heath Aerodrome in March 1919, it disbanded there on 30 June of that same year.

Reformation and the Second World War
No. 107 squadron was reformed at RAF Andover on 10 August 1936 as a light bomber squadron, equipped with Hawker Hinds. These were replaced by Blenheim Mk.Is from August 1938 which gave way in their turn to Blenheim Mk.IVs in May 1939. It was with four of this aircraft that no. 107 took part in the RAF's first bombing raid of the war against enemy ships in the German port of Wilhelmshaven on 4 September 1939, the day after war was declared on Germany. The raid was no success: of the four aircraft despatched only one returned – and with its bomb load still intact as it had not been able to locate the enemy. The first British Prisoner of war in World War II was Sergeant George Booth, a navigator with 107 Squadron. He was captured when his Bristol Blenheim was shot down over the German coast on that 4 September 1939. In April 1940 the squadron carried out attacks on German forces engaged in the invasion of Norway and after the invasion of France and the Low Countries in May 1940 began attacking enemy columns and communications. Following the Dunkirk evacuation the squadron became engaged with attacking invasion barges and shipping concentrations in the Channel ports. In one of these attacks the new Commanding Officer, Wing Commander Basil Embry was shot down. He had taken over the squadron shortly after the disastrous first war mission in September 1939 and had taught the squadron the need for a tight formation for mutual defence which served the squadron time and again. The adventurous story of his escape from captivity eventually reached book form.

In Coastal Command
Between 3 March 1941 and till May 1941, the squadron was on loan to RAF Coastal Command and stationed at RAF Leuchars. Its duties while in Coastal Command were various: shipping strikes, convoy duties, coastal patrols, submarine searches and attacks on enemy airfields and harbours. These were quite hazardous as the squadron lost two COs during these operations, Wing Commander Cameron in April and Wing Commander Birch on 4 May 1941.

To Malta
On return to RAF Bomber Command the squadron took up its low-level daylight raids again until August of that year, when the aircraft of the unit and their pilots -the air detachment of the squadron- were sent to Malta. From there anti-shipping missions were carried out along the Axis' north-south convoy routes, around the Italian coast, Sicily, and along the North African coast. However, after the Italian and German airforces strengthened the air defence of Sicily in December, 1941, and began round-the-clock bombing of the Malta airfields, the air detachment was withdrawn and disbanded at Luqa on 12 January 1942. Losses among the squadron had been so heavy – 90% of all original and replacement crews were killed in action during the Malta operations – that at one time the squadron was commanded by a sergeant, I.G. Broom. It was not the last time this man was in command of a RAF unit, he ended his career as Air Marshal Sir Ivor Broom.

Bostons and Mosquitoes
In the meantime the rest of the squadron, forming the ground echelon, had remained at Great Massingham, Norfolk and on 5 January 1942, it received Douglas Boston trainers and new aircrews, and began converting them onto this aircraft. The squadron began flying daylight operations again in March 1942 and these were continued until February 1944, when the squadron received Mosquito Mk.VIs and switched to night intruder operations instead with these. In November the squadron moved onto the continent, flying from Cambrai and later from Melsbroek. The squadron continued to fly in the night intruder role to the end of war, when it ook up the duty of training in the light bomber role. Remaining in Germany as part of the British Air Forces of Occupation (BAFO) after the war, it was disbanded on 4 October 1948 at Wahn by being renumbered to No. 11 Squadron RAF. (Though some sources claim 15 September 1948)

On Thor missiles
When the Thor Intermediate Range Ballistic Missile were employed in the UK each operating missile squadron was originally meant to control three sites. 107 squadron so started out in September 1958 by being the 'C' flight of the first RAF Thor missile unit, No. 77 Squadron RAF. The flight was stationed at RAF Tuddenham. By June 1959 the flights had reached squadron strength and in September 1959 it was decided that such sites should carry their own identities, 'C' flight of 77 squadron was thus redesignated to No. 107(SM) Squadron RAF, to be effective from 22 July 1959, making no. 107 squadron one of the twenty RAF squadrons that reached operational status using the Thor missile. This new incarnation of no. 107 squadron did not last long though. The upcoming ICBM missiles soon made the Intermediate Range Ballistic Missile obsolete, and in 1962 the Minister of Defence announced the phase-out of the Thor missiles. The squadron therefore disbanded once again, at Tuddenham on 10 July 1963.
