"HMS Revenge in Dry Dock, Portsmouth, 1918" image: a view of the looming bow of the Royal Navy battleship HMS Revenge whilst undergoing maintenance in dry dock at Portsmouth. The huge ship is tethered to the dockside and supported against the side of the dock with large struts. The lower half of the hull, usually below the water level, is a rusty orange colour. Only the tallest part of the ship's superstructure is visible at the top of the composition.
