HMS Express (P163) is an Archer-class P2000-type patrol and training vessel of the British Royal Navy. Express was the only P2000-type vessel in the fleet to retain the black hull inherited from the original operator; the RNXS. She was also the only black-hulled surface vessel in the entire Royal Navy (all submarines are black). However, as the photograph shows, by April 2010 her hull was painted the standard Royal Navy battleship grey. Up to 12 students from Wales URNU can be accommodated on board, as well as 5 permanent ships company drawn from the Royal Navy.
