At the moment there are only enough operational Typhoons to man the Coningsby based Southern QRA unit on a monthly basis (3 squadrons Typhoons and 25 squadrons Tornado F3s alternate between the role every month), not the Leuchars based Northern QRA which was involved in these intercepts.
Given time the Typhoon will be fielded on the front line in sufficient numbers to completely take over the task (2009?)
