Britain's Royal Air Force has joined the US Air Force for huge training exercise in the skies over the North Sea.
More than 50 aircraft flew in Exercise Point Blank on Thursday.
The RAF was also joined by the Royal Netherlands Air Force.
US bomber planes took part for the first time this year, with other aircraft joining from an American base in Italy and USAF’s Europe and Africa units.
The annual operation is designed to hone tactics and ensure readiness.
Colonel Jason Camilletti, commander of USAF’s 48th Fighter Wing, based at RAF Lakenheath in Suffolk, said: “What started as a small grassroots training initiative between the US and Royal air forces has now grown into an adaptable large-scale exercise capable of incorporating joint service and multinational assets across the spectrum of conflict.
“We stand in lock-step with our British and Nato counterparts, and are proud that our collective efforts ensure that we are always ready to own the skies.”
Aircraft in the exercise included F-15s, F-16s, F-35s, Typhoons, B-52s, and KC-135s.
