HMS SMITER is part of the 1st Patrol Boat Squadron (1PBS). 1PBS consists of 16 patrol ships, 14 of which are assigned to URNUs, while the remaining 2 form the Faslane Squadron providing protection to submarines transiting to and from the submarine base HMS CLYDE.

Her primary mission is to support the URNU's activities but she also conducts other Royal Navy tasking. This includes anything from Warfare Officer training to attending high profile events and representing the Royal Navy across the country often with officer cadets embarked to assist.

The Ship's Company of HMS SMITER comprises of 5 full time Royal Navy personnel: the Commanding Officer, 2 senior ratings and 2 junior ratings. They train up to 10 officer cadets for up to 12 days at a time. Sea training affords the officer cadets the opportunity to put into practice the navigation, seamanship skills and theory learnt at weekly Drill Nights during the University term. Throughout the year HMS SMITER takes students to sea for weekends and deployments at Easter and Summer.
