HMS E23 was an E-class submarine built by Vickers, Barrow-in-Furness. She was laid down on 28 September 1914 and was commissioned on 6 December 1915. E23 torpedoed the German dreadnought {{SMS|Westfalen}} (18,900 tons), holing her off Terschelling on 19 August 1916. E23 was sold on 6 September 1922 in Sunderland.{{cite book |last1=Hutchinson |first1=Robert |title=Jane's submarines : war beneath the waves from 1776 to the present day |date=2001 |publisher=HarperCollins |location=London |isbn=978-0007105588}}
Design
Like all post-E8 British E-class submarines, E23 had a displacement of {{cvt|662|LT|t}} at the surface and {{cvt|807|LT|t}} while submerged. She had a length of {{cvt|180|ft|m}} and a beam of {{cvt|22|ft|8.5|in}}.{{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}} She was powered by two {{cvt|800|hp}} Vickers eight-cylinder two-stroke diesel engines and two {{cvt|420|hp}} electric motors.Akerman, P.

British E-class submarines had a fuel capacity of {{cvt|50|t|ST}} of diesel and ranges of {{cvt|3255|nmi|mi+km}} when travelling at {{cvt|10|kn|mph+km/h}}. E23 was capable of operating submerged for five hours when travelling at {{cvt|5|kn|mph+km/h}}.
E23 was armed with a QF 12-pounder 12 cwt naval gun QF gun, mounted forward of the conning tower. She had five 18-inch (450 mm) torpedo tubes, two in the bow, one either side amidships and one in the stern with ten torpedoes on board.
E-class submarines had wireless systems with {{cvt|1|kW}} power ratings; in some submarines, these were later upgraded to {{cvt|3|kW}} systems by removing a midship torpedo tube. Their maximum design depth was {{cvt|100|ft}} although in service some reached depths of below {{cvt|200|ft}}. Some submarines contained Fessenden oscillator systems.
Crew
Her complement was three officers and 28 men.
