She is also available at any time to conduct military tasking as directed by the Commander in Chief Fleet.

The undergraduates are studying towards a variety of degrees and from a wide range of backgrounds; their common ground is a general interest in the Royal Navy (not necessarily as a career), a positive attitude to embrace new challenges and the potential to become the leaders of tomorrow.

Upon a successful first year of training, members are awarded the honorary rank of midshipmen. 

The Yorkshire Universities Royal Naval Unit recruits its new entry undergraduates in the month of September each year. If you are interested in joining (remember this is University Royal Naval Unit and NOT the Royal Navy – therefore there is no liability for call up) then please contact us at: 

Yorkshire URNU, Carr Lodge, Carlton Barracks, Carlton Gate, Leeds, LS7 1HE
