The numbers of personnel based at RAF Menwith Hill are given below, and are current as of 8 November 2017:

US Military


US Contractors


US Civilians


UK Military

7 (5 RN; 2 RAF)

UK Contractors


UK Civilians


The number of GCHQ employees is included in the overall figure for UK civilians as it is Government practice not to disclose the number of personnel working in intelligence at specific locations.

The US authorities do not release a detailed breakdown of US civilian personnel; therefore the overall total of US civilians has been provided.
