Roland,
Surely QRA is a tactical role? A strategic role is something like delivering the nuclear deterrent. QRA in modern parlance could be fulfilled by a Type 45 in the N North Sea depending on the ROE in force. Presumably the Typhoons launching to meet the Bear are doing nothing more than the RN do when intercepting and shadowing Russian warships...mostly for the
PR image.
Re ownership of maritime surveillance....the current capability is owned by the RN (FAA Helos, warships and submarines). IF a wide area capability is reintroduced there is bound to be an ownership discussion. It is not an anti-RAF view, just common- sense.
