No. 151 Squadron was a squadron of the Royal Air Force.
World War I
No. 151 squadron was founded at Hainault Farm in Essex on 12 June 1918, and was equipped with Sopwith Camel aircraft. During the five months in which 151 Squadron had taken part in hostilities overseas, the total number of hours flown by night was 1443 hrs 26 mins.
Sixteen enemy aircraft were destroyed at night on the Allies side of the lines, and five were destroyed on the enemy side and confirmed. Another five were unconfirmed, thus making a total of twenty six successful engagements. Of the enemy aircraft destroyed, twenty two were AEGs, Friedrichshafen or Gothas, with two engines and carrying a crew of three or more. Two were giant P 52's with five engines carrying a crew of up to eight or nine.
During all the numerous combats there were very few occasions when the guns jammed or caused trouble, reflecting the devotion to duty of Lt Eggar and his gunnery staff.
Too much cannot be said for the NCOs and men of the Squadron. The long hours from dawn to dusk and the urgent necessity of getting all machines serviceable during the daytime was evidence of their keen spirit and esprit de corps, and nothing was more gratifying to a pilot on landing after a successful combat than to hear the rousing cheers of the NCOs and men of his Flight, echoed by the Squadron, that greeted him."— George Kelsey on www.151squadron.org, 
The squadron was disbanded on 10 September 1919. Though it had no aces among its members, future Air Vice Marshal Quintin Brand came close; he scored his final four victories while in the squadron.
World War II
On 4 August 1936 the squadron was reformed at RAF North Weald from 'B' Flight of 56 Squadron, as a fighter squadron, flying Gloster Gauntlets. In December 1938 these were exchanged for Hawker Hurricanes, when the squadron came under Squadron Leader Edward Mortlock Donaldson. It operated throughout the Second World War, flying with Hawker Hurricanes, Boulton Paul Defiants and later de Havilland Mosquitoes, disbanding on 10 October 1946 at RAF Weston Zoyland.
After World War II
The squadron was reformed again at RAF Leuchars, Scotland on 15 September 1951 as a night fighter unit, initially operating De Havilland Vampire NF.10s and later Gloster Meteor NF.11s. It disbanded on 19 September 1961.
On 1 January 1962 the Signals Development Squadron at RAF Watton was redesignated as No. 151 Squadron operating a variety of aircraft on development and training duties. It was joined by the pilots and ground crew from the disbanded No. 97 (Strategic Missile) Squadron from RAF Hemswell on 25 May 1963.
On 18 September 1981 151 Squadron reformed at RAF Chivenor as part of number 2 TWU operating BAE Hawk T1 & T1A aircraft. When 2 TWU became 7 FTS in 1992, 151 Squadron was disbanded and its duties taken over by 92 Squadron.
