Design
Like all pre-H21 British H-class submarines, H11 had a displacement of {{convert|364|LT|t}} at the surface and {{convert|434|LT|t}} while submerged.{{cite web|url=http://www.battleships-cruisers.co.uk/h_class1.htm|title=H-class|publisher=Battleships-Cruisers, Cranston Fine Arts|accessdate=20 August 2015}} 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}}. It contained a diesel engines providing a total power of {{convert|480|hp}} and two electric motors each providing {{convert|320|hp}} power.{{Cite Colledge2006}} Retrieved from [http://www.naval-history.net/WW1NavyBritishShips-Dittmar3WarshipsA.htm#10 Naval-History] on 20 August 2015. 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}}.{{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.

The submarine had a maximum surface speed of {{convert|13|kn|km/h mph}} and a submerged speed of {{convert|11|kn|km/h mph}}. British H-class submarines had ranges of {{convert|1600|nmi|km mi}} at speeds of {{convert|10|kn|km/h mph}}. H11 was fitted with a {{convert|6|lb}} Hotchkiss quick-firing gun (6-pounder) and four {{convert|18|in}} torpedo tubes. Its torpedo tubes were fitted to the bows and the submarine was loaded with eight {{convert|18|in}} torpedoes. It is a Holland 602 type submarine but was designed to meet Royal Navy specifications.
