Title: HMS E8
Content:  class boats were armed with four 18 inch (450 mm) torpedo tubes, one in the bow, one either side amidships, and one in the stern; a total of eight torpedoes were carried. Group 1 boats were not fitted with a deck gun during construction, but those involved in the Dardanelles campaign had guns mounted forward of the conning tower while at Malta Dockyard. E-Class submarines had wireless systems with 1 kW power ratings; in some submarines, these were later upgraded to 3 kW systems by removing a midship torpedo tube. Their maximum design depth was 100 ft although in service some reached depths of below 200 ft.
Title: HMS E8
Content:  The early British E-class submarines, from E1 to E8, had a displacement of 652 t at the surface and 795 t while submerged. They had a length overall of 180 ft and a beam of 22 ft, and were powered by two 800 hp Vickers eight-cylinder two-stroke diesel engines and two 420 hp electric motors. The class had a maximum surface speed of 16 kn and a submerged speed of 10 kn, with a fuel capacity of 50 t of diesel affording a range of 3225 mi when travelling at 10 kn, while submerged they had a range of 85 mi at 5 kn.

Title: HMS E8
Content:  When war was declared with Germany on 5 August 1914, E8 was based at Harwich, in the 8th Submarine Flotilla of the Home Fleets. On that morning the destroyers and  towed E8 and, respectively to Terschelling. E8 and E6 then made the first Heligoland Bight patrol of World War I. On 23 October 1915, E8 sank the 9,050-ton, three-funnel German armoured cruiser 20 nmi in the Baltic Sea west of Libau. As the result of this action the submarine's commander, Commander Francis Goodhart, received the Cross of St. George from Tsar Nicholas II. During her time in the Baltic, Aksel Berg, who later became the founder of Soviet cybernetics, was her liaison officer.
Title: HMS E38
Content:  when travelling at 5 kn. E38 was armed with a 12-pounder 76 mm 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; a total of 10 torpedoes were carried. E-Class submarines had wireless systems with 1 kW power ratings; in some submarines, these were later upgraded to 3 kW systems by removing a midship torpedo tube. Their maximum design depth was 100 ft although in service some reached depths of below 200 ft. Some submarines contained Fessenden oscillator systems.
Title: HMS E8
Content:  HMS E8 was a British E-class submarine built at Chatham Dockyard. She was laid down on 30 March 1912 and was commissioned on 18 June 1914. She cost £105,700. During World War I she was part of the British submarine flotilla in the Baltic.
Title: HMS E48
Content:  Like all post-E8 British E-class submarines, E48 had a displacement of 662 t at the surface and 807 t while submerged. She had a total length of 180 ft and a beam length of 22 ft. She was powered by two 800 hp Vickers eight-cylinder two-stroke diesel engines and two 420 hp electric motors. The submarine had a maximum surface speed of 16 kn and a submerged speed of 10 kn. British E-class submarines had fuel capacities of 50 t of diesel and ranges of 3255 mi when travelling at 10 kn. E48 was capable of operating submerged for five
