Prince William is back after being deployed to the Falklands, St James's Palace said on Wednesday.
A royal spokesperson told The Huffington Post UK the Duke of Cambridge arrived in Brize Norton with a four-man crew on Wednesday morning.
"Prince William's come back from the Falklands. He got back to Brize Norton this morning," they said.
The Duke of Cambridge was deployed to the Falklands in February, amid heightening tensions with the country as the 30th anniversary of the Falklands war approaches. The Argentinian foreign minister said at the time William would be arriving in "the uniform of a conqueror".
In an interview with the country's La Red radio station, Argentina's Vice-president Amado Boudou said that the move was a case of "bravado" to mask high unemployment and the prospect of Scottish independence.
"In Europe they are trying to cover up problems such as unemployment and social dissatisfaction by seeking issues which have high media impact.
"They are seeking to cover up daily reality with a matter which is very far away from London, such as the Malvinas [the Argentinean term for the disputed islands].
The Ministry of Defence issued photographs of William in his role as an RAF search and rescue helicopter pilot during his tour of duty.
In one shot the 29-year-old is sitting at the controls of a yellow Sea King helicopter leafing through papers, concentration etched on his face.
The images also show William, who is part of a four-man team, consulting maps with a colleague in a squadron operations room.
