The RAF operate three marks of the Britten-Norman Islander. The first aircarft accuired was Serial ZF573 a CC.2A varient which was delivered on the 1st April 1991. This Islander was orginally intended as a stop gap until ZH536 was delivered, but eventually became based. The aircraft was initially operated in a blue and white scheme but was repainted in the standard grey scheme by June 1993 which it still wears today.

A second Islander a CC.2 varient, Serial ZH536 was delivered on the 17th December 1992. A third aircraft was accuired in April 2008 when ZH537 a Islander CC.2B was delivered, this airframe once served with the United Arab Emirates Air Force.

These three aircraft form the Northolt Station Flight at RAF Northolt, near London and are flown in a classified surveillance role and perform electronic intelligence gathering.
