The New Chief of the Air Staff has taken up his post.
Air Chief Marshal Sir Stephen Hillier becomes head of the RAF today.
Previously he was Deputy Chief of the Defence Staff, in charge of military capability at the Ministry of Defence.
Sir Stephen, a Tornado GR4 pilot and flying instructor, has more than 3,500 hours in the air.
After serving in the First Gulf War he was awarded the Distinguished Flying Cross in 1999, during Operation Southern Watch. He was awarded the US Bronze Star Medal during the Iraq War in 2003.

He follows Air Chief Marshal Sir Andrew Pulford, who is retiring from the service.
Sir Stephen's appointment reportedly came under fire last year from a former First Sea Lord.
Admiral The Lord West of Spithead said the decision to put a man who has never served at sea in charge of Royal Navy's new £6.2bn aircraft carriers, as well as more than 20 F-35 jets and Merlin helicopters, was 'barking mad', and claimed it would 'make Britain an international laughing stock', according to the Daily Star.
But the MoD said Sir Stephen was picked for his skills in 'leadership and experience in delivering complex programmes across defence'.
