It was formed in August 1941, as the 2nd Polish Fighter Wing, from three Polish squadrons, the
No. 302 Polish Fighter Squadron and
No. 316 Polish Fighter Squadron, and the
No. 317 Polish Fighter Squadron. Its composition was not stable, as Polish Squadrons were frequently exchanged between the three Polish wings (the
No. 131 Wing RAF (1st Polish) wing, the No. 133 Wing (2nd Polish) wing, and the
3rd Polish Fighter Wing). At various times, this wing included other Polish squadrons, such as the
No. 306 Polish Fighter Squadron,
No. 309 Polish Fighter-Reconnaissance Squadron and the
No. 315 Polish Fighter Squadron. The number of Polish wings was also not constant, varying from at least two to four. On 1 November 1943
No. 1 Polish Wing RAF was renamed to
No. 133 Airfield Headquarters (Polish) RAF while the unit was at
RAF Heston under
No. 18 Wing RAF and controlling
No. 306 Polish Fighter Squadron and
No. 315 Polish Fighter Squadron both operating Spitfires. The wing moved to
RAF Coolham on 1 April 1944 and was renamed to
No. 133 Wing RAF on 12 May 1944.
No. 133 Wing RAF was formed on 12 May 1944 at
RAF Coolham. ==See also==
