'''HMS ''E2''''' (originally ordered as HMS ''D10'') was a [[British E class submarine]] built by [[Chatham Dockyard]]. ''E2'' was laid down on 14 February 1911 and launched on 23 November 1912.

She was sold 7 March 1921 to B Zammit, [[Malta]].

==Design==
The early [[British E-class submarine]]s, from ''E1'' to ''E8'', had a displacement of {{convert|652|LT|t}} at the surface and {{convert|795|LT|t}} while submerged. They had a length overall of {{convert|180|ft|m}} and a beam of {{convert|22|ft|8.5|in}}, and were powered by two {{convert|800|hp}} Vickers eight-cylinder two-stroke diesel engines and two {{convert|420|hp}} electric motors.<ref name=Akerman>Akerman, P. (1989). ''Encyclopaedia of British submarines 1901&ndash;1955''. &nbsp;p.150. Maritime Books. {{ISBN|1-904381-05-7}}</ref><ref>{{cite web|url=http://www.csubmarine.org/html/class/eclass.html|title=E Class|publisher=Chatham Submarines|accessdate=20 August 2015|archive-date=13 August 2015|archive-url=https://web.archive.org/web/20150813023119/http://csubmarine.org/html/class/eclass.html|url-status=dead}}</ref> The class had a maximum surface speed of {{convert|16|kn|km/h mph}} and a submerged speed of {{convert|10|kn|km/h mph}}, with a fuel capacity of {{convert|50|LT|t}} of diesel affording a range of {{convert|3225|mi|km nmi}} when travelling at {{convert|10|kn|km/h mph}}, while submerged they had a range of {{convert|85|mi|km nmi}} at {{convert|5|kn|km/h mph}}.<ref name=Akerman/>

The early 'Group 1' ''E'' class boats were armed with four [[British 18 inch torpedo|18 inch (450 mm)]] [[torpedo tube]]s, one in the bow, one either side amidships, and one in the stern; a total of eight torpedoes were carried. Group 1 boats were not fitted with a deck gun during construction, but those involved in the Dardanelles campaign had guns mounted forward of the conning tower while at Malta Dockyard.<ref name=Akerman/>

E-Class submarines had wireless systems with {{convert|1|kW}} power ratings; in some submarines, these were later upgraded to {{convert|3|kW}} systems by removing a midship torpedo tube. Their maximum design depth was {{convert|100|ft}} although in service some reached depths of below {{convert|200|ft}}. Some submarines contained [[Fessenden oscillator]] systems.<ref name="McCartneyBryan2013">{{cite book|author1=Innes McCartney|author2=Tony Bryan|title=British Submarines of World War I|url=https://books.google.com/books?id=JWFapIxWZSUC&pg=PA11|date=20 February 2013|publisher=Osprey Publishing|isbn=978-1-4728-0035-0|pages=11–12}}</ref>

==Crew==
Her [[Ship's company|complement]] was three officers and 28 men.<ref name="McCartneyBryan2013"/>

==Service history==
When [[World War I|war]] was declared with [[German Empire|Germany]] on 5 August 1914, ''E2'' was based at [[Harwich]], in the [[8th Submarine Flotilla]] of the [[Home Fleet]]s.<ref>{{cite book |title=Position and Movements, H.M. Ships, War Vessels and Aircraft, British and Foreign, Parts I. and II., August 1914. |date=1914 |publisher=Admiralty Records |location=London}}</ref>

On 14 August 1915,  ''E2'' sank Turkish minelayer Samsun with her two officers and eight crew near [[Erdek]].
