Like all post-''E8'' [[British E-class submarine]]s, ''E11'' had a displacement of {{convert|662|LT|t}} at the surface and {{convert|807|LT|t}} while submerged. She had a total length of {{convert|180|ft|m}}<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> and a beam of {{convert|22|ft|8.5|in}}. She was 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).

''E11'' initially did not have a deck gun.<ref name=DP>{{cite book | title = "Dardanelles Patrol" | last = Shankland, Peter and | first = Hunter, Anthony | location = [[New York City|New York]] | publisher= Charles Scribner's Sons | year = 1964 | oclc = 6420053 }}</ref> After her first Dardanelles tour, she was fitted with a [[QF 12-pounder 12 cwt naval gun|12-pounder {{convert|76|mm|abbr=on}}]] QF by the dockyard in Malta.<ref>{{cite book |title=Conway's All the World's Fighting Ships 1906–1921 |date=12 November 1985 |publisher=Conway Maritime Press |location=London |isbn=0-85177-245-5 |page=88}}</ref>

She had five [[British 18-inch torpedo|18-inch (450 mm)]] [[torpedo tube]]s, two in the bow, one either side amidships, and one in the stern; a total of 10 torpedoes were carried.<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"/>
