Royal Air Force Typhoon fighter jets have undertaken a series of exercises with visiting US B-52 bombers for the second time this year.
Based at Raf Coningsby, the fighter jets flew alongside the US Air Force aircraft and carried out a practise intercept.
The move is the latest in a series of air integration training between the two airforces, which have been training together to practice flying missions in a hostile air environment.
According to the RAF, the latest training exercise marks a shift away from counter-insurgency operations carried out in recent years.
Air Officer Commanding 11 Group, air vice-marshal Ian Duguid, said: “We have a longstanding and rewarding partnership with the United States Air Force having worked successfully together on operations and exercises and as part of NATO . That success is built on mutual respect and cooperation.”
Duguid said: “The RAF is involved in operations with partners around the world and our commitment to the Nato alliance remains as steadfast as ever.”
The Typhoons carry out a range of duties, including the UK’s Quick Reaction Alert force, which is responsible for intercepting foreign or suspicious aircraft entering UK airspace.
The aircraft recently completed a Nato Baltic Air Policing mission in Estonia. RAF Typhoons completed 21 interceptions of 56 Russian aircraft in the skies above Estonia over the four-month deployment, dubbed Operation Azotize.
Later this year, the aircraft will carry out a similar Nato air policing mission in Iceland at the request of the Icelandic Government. It will be the RAF’s first operational deployment to Iceland since the Second World War.
