Britain's new aircraft carrier HMS Queen Elizabeth sighted in River Forth as £6billion fitting-out of Royal Navy's biggest ever ship continues

Britain's largest warship is still being fitted out at Rosyth Dock in Fife seven years after contracts were first agreed

The vessel's nine-deck hull is taking form with 10,000 shipyard workers and engineers working on the project 

Vessel was first unveiled in July 2014 and floated on the River Forth after Rosyth Dock was filled with water 

The cost of the project has spiraled from £3billion in 2007 to more than an estimated £6billion by completion in 2020

HMS Queen Elizabeth is as tall as Nelson's Column at 230ft, weighs 65,000 tonnes and measures 918ft bow to stern
