It's about 920 feet in length, around 230 feet wide in girth with maximum planned displacement exceeding 70,000 tonnes and about as big as any ship can be at this location in the Firth of Forth Estuary. At first glance, it appears bizarre with its curiously shaped twin towers designed according the rules of 'radar contouring' to minimise detection by that means. It matches the largest oil tanker ever to safely progress towards this spot and where the combined efforts of A&P, Govan Shipyards, Cammel Laird and Babcock Fife have come together in a huge project to design, create and then ultimately unite the hull sections together at the Rosyth Dockyard in Fife. It's the biggest aircraft carrier ever built for use by the British Royal Navy with intent to enter service circa 2017 and expected to remain in service for fifty years. A second ship of similar design and construction, called 'Prince of Wales' is under construction with an entry date of service in 2020.
