HMS Explorer

HMS Explorer is an Archer-class P2000-type patrol and training vessel of the British Royal Navy. The ship is primarily assigned to the Yorkshire Universities Royal Naval Unit (URNU), serving the universities of Hull, Sheffield and Leeds. The ship is based in Kingston-Upon-Hull and mainly operates on the East coast of the UK, particularly in and around the Humber estuary.
HMS Explorer is the second ship to bear the name; her predecessor was an unarmed experimental Walter-turbine submarine based on the captured high test peroxide (HTP) powered German Type XVIIB submarine U-1407 launched in 1956 and scrapped in 1965.
