UK - London - Battleship on Thames
I've gone for quite a mean and moody post-production for this shot (rather than just underexpose it as some might think.....), it seemed to suit this photo of the HMS Ocean sat on the Thames. She's the largest warship in the Royal Navy and has been 'parked' in London as part of the Olympics security operation.
From Wikipedia : "HMS Ocean of the Royal Navy is an amphibious assault ship (or landing platform helicopter) and is the sole member of her class. She is designed to support amphibious landing operations and to support the staff of Commander UK Amphibious Force and Commander UK Landing Force.
She was constructed in the mid 1990s by Kvaerner Govan Ltd on the Clyde and fitted out by VSEL at Barrow-in-Furness prior to first of class trials and subsequent acceptance in service. She was commissioned in September 1998 at her home port HMNB Devonport, Plymouth."
