These naval guns outside the Imperial War Museum are two British BL 15-inch Mk I guns from World War I. The gun on the left is from the HMS Ramillies, and the one on the right is from the HMS Resolution (which was later remounted on the HMS Roberts). They were installed in 1968 and have a range of over 15 miles.
