HM Submarine X1 was a British submarine of the interwar period. Conceived and designed as a submersible commerce raider for the Royal Navy; at the time of her launching she was the largest submarine in the world. For Britain, the idea of a submarine cruiser had been proposed as early as 1915, but the type was not put into practice until after the end of World War I in 1918. X1 was laid down on 2 November 1921 at HM Dockyard, Chatham and completed on 23 September 1925 with commissioning following in December 1925.

The 1922 Washington Naval Treaty, of which Britain was a signatory, did not ban submarines but it did ban their use against merchant ships, which was X1Шаблон:'s unacknowledged purpose; its armament had been designed to successfully engage the classes of vessels likely to be escorting convoys, such as destroyers and frigates. Therefore, a certain amount of secrecy surrounded X1, the government even going to the lengths of taking a national newspaper to court over its pictures of the new submarine following her launch, all copies of the paper being seized.Шаблон:Cn

Description

The X1Шаблон:'s Шаблон:Convert thick pressure hull was Шаблон:Convert in diameter amidships, and was divided into 10 watertight compartments. This was almost completely surrounded by her external hull, which also contained the main ballast tanks and most of her fuel. Her intended maximum diving depth was Шаблон:Convert, but was reduced to Шаблон:Convert once in service.[1]

Armament

X1 carried four QF 5.2 inch Mk I guns[2] in twin unarmoured turrets, one forward and one aft of the conning tower. They had a range of about Шаблон:Convert. A circular trunk ran from each mounting to the magazine in the pressure hull which contained 100 rounds per gun. A working chamber which was Шаблон:Convert in diameter encircled the trunk between the pressure hull and the gun mount.[1] Her ammunition hoists were problematic and could not sustain the desired rate of fire of six rounds per gun per minute. Special ballast tanks were used to compensate for the loss of weight as ammunition was fired. Working and control of the guns required 58 men.[3] The fire-control tower was in the middle of the conning tower and had a top section that could be raised Шаблон:Convert when in use. The upper control room was between the tower and the pressure hull. Just aft of the control room was the rangefinding room, with a Шаблон:Convert rangefinder on the bridge that could be raised Шаблон:Convert.[1]

Her six bow tubes for [[British 21 inch torpedo|Шаблон:Convert torpedoes]] came from a cancelled L-class submarine and she was provided with one reload for each tube. It took 24 minutes to reload them all because space in the torpedo room was restricted.[3]

Propulsion

The main engines were two 8-cylinder Admiralty diesel engines with a total output of Шаблон:Convert. Two auxiliary Шаблон:Convert MAN diesel engines taken from the German submarine U-126 were installed for battery-charging purposes. For underwater propulsion, two GEC electric motors of Шаблон:Convert each were fitted. It was hoped to achieve over Шаблон:Convert using both diesels and electric motors together, but the highest power achieved (during a full power trial in March 1926) was Шаблон:Convert. She had three groups of batteries, each with 110 cells weighing a total of Шаблон:Convert.[4] In theory she could make Шаблон:Convert on the surface, and at economical speed she had a greater range than normal cruisers, but both sets of diesel engines suffered from continual mechanical problems that reduced her speed and range.[4] The X1Шаблон:'s average diving time to periscope depth was 2 minutes 20 seconds. Her handling underwater was considered superior to other submarines of the period.[5]

Career

After X1 was commissioned in December 1925 and accepted in April 1926 she made a voyage to Gibraltar after which her main engine drive wheels were found to be damaged. After repairs she was sent to the Mediterranean Sea. Her starboard camshaft driveshaft broke during a full-power run in January 1928 and a new set of gears was needed, but after refitting at Malta her port camshaft driveshaft broke in the same place in April 1928. By 1930 her commanding officer reported "internal arrangements not very satisfactory because of overcrowding with auxiliary machinery, accommodation is cramped, ventilation poor and the ship suffers from humidity, diving arrangements good."[4] Both the main and auxiliary engines were troublesome and she spent most of her time under repair, before being laid up.[4] X1 was placed in reserve after 1930, before she was finally scrapped at Pembroke on 12 December 1936.[5]
