Liverpool University Royal Naval Unit (Liverpool URNU) is one of 14 URNUs in the country, and the oldest after the disbanding of Aberdeen URNU. The aim of the URNU is to 'provide high-quality sea training experiences to undergraduates from universities, developing seamanship, teambuilding and leadership skills in a maritime environment.' Liverpool URNU recruits undergraduates from the Universities of Liverpool, Lancaster and John Moores. Over 50 students attend drill evenings and other activities ashore.
Sea time is combined with time aboard Charger at weekends, when she visits local ports such as Holyhead, Douglas, Preston, Fleetwood, Barrow-in-Furness, Salford, Ellesmere Port, Maryport and Whitehaven and deployments during the Easter and Summer holidays when she visits ports around the UK and Northern Europe. In 2011 Charger deployed to the Baltic, visiting ports in Belgium, the Netherlands, Germany and Denmark and transiting both the Caledonian and Kiel Canals. The ship is affiliated to the Cumbrian town of Maryport and regularly visits the town during deployments and for Remembrance Day ceremonies.
In 2012, the ship's frequent visits to Preston resulted in the ship being formally adopted by the people of Preston. In 2013, Charger, became the first Royal Navy vessel in the 21st century to make the journey up the River Weaver to Northwich.
Charger flies the White Ensign at events such as the Liverpool Spring on the Waterfront, the Mersey River Festival, the Whitehaven Festival, the Northern Ireland International Airshow, the start of the 2007 Clipper Round the World Yacht Race and the Honda Powerboat Championships.
