Formation and World War I

Despite its high squadron number, 201 Squadron is one of the oldest squadrons in the RAF. It was formed as No. 1 Squadron of the Royal Naval Air Service (RNAS) on 17 October 1914, and reformed under that designation on 6 December 1916,^[13] only being renumbered to 201 Squadron on the formation of the RAF on 1 April 1918 – all the RNAS squadrons getting new numbers by adding 200 to their original number.^[2]

A Victoria Cross was won by a member of No. 1 Squadron RNAS when on 7 June 1915 Sub-Lieutenant R.A.J. Warneford shot down Zeppelin LZ.37.^[14]

After the war the squadron was disbanded at RAF Eastleigh on 31 December 1919.^[2][13] Eighteen flying aces served in the squadron during the course of the war, including such notables as Samuel Kinkead, Stanley Wallace Rosevear, Richard Minifie, Roderic Dallas, George Gates, Reginald Brading, Maxwell Findlay, Cyril Ridley, Thomas Gerrard, John Jones, James Henry Forman, Charles Dawson Booker, Thomas Culling, future Air Vice-Marshal F. H. Maynard, Robert McLaughlin, and Hazel Wallace.^[15]

Flying boat squadron

The squadron was reformed at RAF Calshot on 1 January 1929 by expanding no. 480 Flight, a Supermarine Southampton flying boat unit. In April 1936 the Southamptons gave way to the Saro London, which the squadron still had on strength when World War II broke out. Supermarine Stranraers flew shortly with the squadron in 1939, but by April 1940 the squadron was operational on the Short Sunderland, which would remain the squadron equipment for almost seventeen years up till 28 February 1957, when the squadron was disbanded at RAF Pembroke Dock.^[2][13][16]

Shackletons and Nimrods

The squadron was reformed at RAF St. Mawgan, when No. 220 Squadron RAF was renumbered to 201 Squadron. The squadron flew the next twelve years with the Avro Shackleton MR.3, a version that used a tricycle undercarriage as opposed to the earlier tailwheel variants. Following the Shackleton's retirement, the squadron converted to Nimrods in October 1970.^{[2][13][16][17]}

The squadron was active for over a decade in the Gulf region, in support of both Gulf War 1 and 2 and more recently the conflict in Afghanistan. Until March 2010, the squadron was also on active duty in the UK and maintained continuous 24-hour/365-day search and rescue standby, shared with the sister 120 Squadron, both flying from RAF Kinloss. The Nimrod MR2 was withdrawn in March 2010,^[17] and the squadron was formally disbanded on 26 May 2011.^[18] It had been preparing to operate the Nimrod MRA4 but this aircraft was cancelled under the 2010 Strategic Defence and Security Review.^[19]

Reformation

In July 2017, it was announced that No. 201 Squadron would be one of two RAF squadrons to fly the P-8A Poseidon, based at RAF Lossiemouth.^[20] It was later confirmed the squadron would stand up in the 'Summer of 2021' operating in the role and at location as previously stated.^[21] No. 201 Squadron reformed on 7 August 2021, reclaiming their Squadron Standard from Government House in Guernsey on 22 October.^[3]
