'''HMS ''Alaric'' (P441)''', was an ''Amphion''-class submarine of the Royal Navy, built by Cammell Laird laid down in May 1944 and launched 18 February 1946.<ref>{{cite web|url=http://www.uboat.net/allies/warships/ship/3615.html|title=''Alaric''|publisher=Uboat.net|accessdate=20 August 2015}}</ref>
==Design== Like all Amphion-class submarines, ''Alaric'' had a displacement of {{convert|1360|LT|t}} when at the surface and {{convert|1590|LT|t}} while submerged. She had a total length of {{convert|293|ft|6|in}}, a beam of {{convert|22|ft|4|in}}, and a draught of {{convert|18|ft|1|in}}. The submarine was powered by two Admiralty ML eight-cylinder diesel engines generating a power of {{convert|2150|hp}} each. She also contained four electric motors each producing {{convert|625|hp}} that drove two shafts.<ref name="Akermann2002">{{cite book|author=Paul Akermann|title=Encyclopedia of British Submarines 1901–1955|url=https://books.google.com/books?id=boO7WGL21EQC&pg=PA428|date=1 November 2002|publisher=Periscope Publishing Ltd.|isbn=978-1-904381-05-1|page=422}}</ref> She could carry a maximum of {{convert|219|t|ST}} of diesel, although she usually carried between {{convert|159|and|165|t|ST}}.<ref name="Akermann2002"/>
The submarine had a maximum surface speed of {{convert|18.5|kn|km/h mph}} and a submerged speed of {{convert|8|kn|km/h mph}}.<ref>{{cite web|url=http://www.worldnavalships.com/acheron_class.htm|title=Acheron class|publisher=World Naval Ships, Cranston Fine Arts|accessdate=20 August 2015}}</ref> When submerged, she could operate at {{convert|3|kn|km/h mph}} for {{convert|90|nmi|km mi}} or at {{convert|8|kn|km/h mph}} for {{convert|16|nmi|km mi}}. When surfaced, she was able to travel {{convert|15200|nmi|km mi}} at {{convert|10|kn|km/h mph}} or {{convert|10500|nmi|km mi}} at {{convert|11|kn|km/h mph}}.<ref name="Akermann2002"/> She was fitted with ten {{convert|21|in|mm}} torpedo tubes, one QF 4 inch naval gun Mk XXIII, one Oerlikon 20 mm cannon, and a .303 British Vickers machine gun. Her torpedo tubes were fitted to the bow and stern, and she could carry twenty torpedoes. Her complement was sixty-one crew members.<ref name="Akermann2002"/>
