There has been mounting speculation that all Tornado operations could be moved from Lossiemouth to RAFMarham, where engineering work for the aircraft is already based.
Liz Truss, the MP for South West Norfolk, who had campaigned to keep RAFMarham open when it was threatened with closure, was delighted the new aircraft would be based there.
Mr Hammond said that the Lightning II squadron based at RAFMarham would be a joint RAF and Royal Navy force and the station would be responsible for support and maintenance of both land-based and aircraft carrier planes.
