No. 9 Group RAF

No. 9 Group RAF (9 Gp) was a group of the Royal Air Force, which existed over two separate periods, initially at the end of the First World War, and latterly during the Second World War when its role was air defence.

History
The group was first formed on 1 April 1918 in No. 2 Area. The next month it was transferred to South-Western Area and then disbanded on 15 May 1919.

Its next incarnation was as part of RAF Fighter Command. As 1940 wore on, the need for another Group headquarters to control fighter operations became more and more apparent. No. 9 Group was formed in September 1940 to cover North West England and Northern Ireland. It was based at RAF Barton Hall and initially only controlled No. 308 Polish Fighter Squadron at RAF Speke,

On 1 January 1941 the group was only using the Hawker Hurricane I fighter aircraft:
 * No. 96 Squadron RAF at RAF Cranage
 * No. 229 Squadron RAF at RAF Speke
 * No. 306 Polish Fighter Squadron at RAF Tern Hill
 * No. 308 Polish Fighter Squadron at RAF Baginton
 * No. 312 (Czechoslovak) Squadron RAF at RAF Speke

No. 275 Squadron RAF was formed at RAF Valley on 15 October 1941 as No. 9 Group's Air Sea Rescue unit, to cover the Irish Sea.

9 Group also supplied the staff that were trained by Robert Watson-Watt, the inventor of radar, to operate the Chain Home early warning system. The staff being RAF females (they were never WAAF members).

On 1 May 1942 it consisted of:
 * No. 131 Squadron RAF at RAF Llanbedr with Spitfire
