Like all pre-''H11'' [[British H-class submarine]]s, ''H2'' had a displacement of {{convert|364|LT|t}} at the surface and {{convert|434|LT|t}} while submerged.<ref name="batcru">{{cite web|url=http://www.battleships-cruisers.co.uk/h_class1.htm|title=H-class|publisher=Battleships-Cruisers, Cranston Fine Arts|access-date=20 August 2015}}</ref> It had a total length of {{convert|150|ft|3|in|m|1}}, a beam of {{convert|15|ft|4|in}}, and a draught of {{convert|12|ft|m}}.<ref name="Colledge"/> It contained a diesel engines providing a total power of {{convert|480|hp}} and two electric motors each providing {{convert|320|hp}} power.<ref name="Colledge">{{Cite Colledge2006}} Retrieved from [http://www.naval-history.net/WW1NavyBritishShips-Dittmar3WarshipsA.htm#10 Naval-History] on 20 August 2015.</ref> The use of its electric motors made the submarine travel at {{convert|11|kn|km/h mph}}. It would normally carry {{convert|16.4|LT|t}} of fuel and had a maximum capacity of {{convert|18|LT|t}}.<ref>{{cite web|url=http://www.gwpda.org/naval/hpatsubs.htm|title=Building History and Technical Details for Canadian CC-Boats and the Original H-CLASS|publisher=Electric Boat Company Holland Patent Submarines|author=J.
