A University Royal Naval Unit (URNU) is a Royal Navy training establishment connected to a university, or a number of universities concentrated in one area. There are 15 URNUs nationwide in the UK, and each URNU has land-based facilities near the university in question, up to four training officers (members of the Royal Naval Reserve) and, with the exception of Devon, a dedicated training vessel (an Archer-class P2000 fast patrol boat).
The units and their ships are
URNU ships are part of the 1st Patrol Boat Squadron, or "1PBS". 1PBS is commanded by Commander 1PBS, who previously was also Commander URNU (however Commander Universities is now a separate post). The mission statement of 1PBS is to provide high-quality sea training experiences in support of the URNU mission and to deliver P2000 operational capability in support of other fleet tasking.
The most recently formed unit, Devon URNU was established in 2017, catering to universities across the region. The unit is the only URNU without a dedicated training vessel, but students are able to utilise available P2000s and other craft for training. Devon was the first new unit formed since 1994.
While the URNUs are commanded by Commander URNU they fall under the overall jurisdiction of Commodore BRNC (the officer-in-charge of the Britannia Royal Naval College), Dartmouth. Each URNU is commanded by a Lieutenant RN, Lieutenant Commander or RM Captain, and is associated with a P2000 patrol boat of the 1st Patrol Boat Squadron. Each URNU comprises 51 undergraduates who join for the duration of their degree, with the option of taking years out or leaving at any time.
Undergraduates join for three years, or in some cases the duration of their course. Members hold the rank of honorary Midshipman in the Royal Naval Reserve. A notable difference between this and other ranks in the Royal Navy is that there is no call-up liability and members may leave at any time.
During the first year URNU students wear URNU slides on their shoulders and are Officer Cadets (O/CDTS) and on completion of the first taskbook they receive a white officer cadet tab in addition to the URNU slide. They can then be referred to as Midshipmen RNR(MID) and on completion of the second taskbook students will wear Midshipman "Turnbacks".
Each URNU has a Senior Midshipman (SMID) and Deputy Senior Midshipman (DSMID) with a committee made up of various roles which differ according to unit, but will generally include a treasurer and sports and adventurous training officers alongside other roles, and this committee will take leading role in programme planning and assist in the running of the Unit. The committee is supported by the unit CO and a Coxn, usually a full-time Royal Navy Chief Petty Officer (CPO) as well as a civilian secretary. Each unit also has capacity for up to four training officers, who may be ex-Navy, former URNU students, or civilians with relevant experience, who are appointed as Royal Naval Reserve officers (RNR).
