The winners of the Royal Navy's annual photography competition, known as The Peregrine Trophy, were announced by the First Sea Lord at a ceremony in Greenwich last night.
The competition included entries from Naval photographers deployed in Afghanistan, on counter-piracy operations and other operations both abroad and in the UK.
The winning portfolio came from Leading Airman Arron Hoare, who captured these stunning images of the Antarctic's dramatic wilderness while he served in the ice patrol ship HMS Protector.
Other photographers were awarded for specific categories. Hamish Burke's picture below won the Maritime Air Award, for best photograph of one or more Royal Navy helicopters.
Hamish Burke also won The Royal Navy ‘Life Without Limits’ Award for best photograph of a member of the Royal Navy undertaking their duties.
This picture below shows members of 30 Commando knuckle down on the challenging conditions of the Lashkar gah in Afghanistan.
Another winner was Kyle Taylor for his picture of Royal Marines capturing Somali pirates off the coast of Yemen.
He won the Media Operations Category, awarded to the best single image that is judged to create the most impact as a news photograph.
