Design
Like all post-H20 British H-class submarines, H44 had a displacement of {{convert|423|LT|t}} at the surface and {{convert|510|LT|t}} while submerged.{{cite book |last1=Gardiner |first1=Robert |last2=Gray |first2=Robert |title=Conway's All the World's Fighting Ships 1906-1921 |date=1985 |publisher=Conway Maritime Press |location=London |isbn=0-85177-245-5 |page=92}} It had a total length of {{convert|171|ft|m}},{{cite book|author=Derek Walters|title=The History of the British 'U' Class Submarine|url=https://books.google.com/books?id=VyeJ9DOXcOAC&pg=PA2|year=2004|publisher=Casemate Publishers|isbn=978-1-84415-131-8|pages=2–}} a beam of {{convert|15|ft|4|in}}, and a draught of {{convert|12|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|10.5|kn|km/h mph}}. Post-H20 British H-class submarines had ranges of {{convert|2985|nmi|km mi}} at speeds of {{convert|7.5|kn|km/h mph}} when surfaced. H44 was fitted with an anti-aircraft gun and four {{convert|21|in}} torpedo tubes. Its torpedo tubes were fitted to the bows and the submarine was loaded with eight {{convert|21|in}} torpedoes. It is a Holland 602 type submarine but was designed to meet Royal Navy specifications. Its complement was twenty-two crew members.
