HMS Trenchant to the left, HMS Turbulent is hidden behind the tug. The three submarines were identical with even their periscopes in the same order, although HMS Trafalgar is easily identifiable due to having a blue sheath over it`s sonar array forward of the conning tower.

Crew 130, Length 85mtrs, Width 10mtrs, Displacement 5,200tons.
