The Russian ironclad ''Ne Tron Menia'' ((ロシア語:Не тронь меня)) was the second of the three broadside ironclads built for the Imperial Russian Navy during the mid-1860s. She joined the Baltic Fleet upon completion and never left Russian waters. Beginning in 1870 the ship was assigned to the Gunnery Training Detachment and was frequently rearmed. ''Ne Tron Menia'' was placed in reserve and hulked a decade later. In 1905 the ship was disarmed and she was sold in 1908. After the end of the Russian Civil War, she was acquired by the Soviets before being sold to a factory in 1925. The ship was sunk in the Siege of Leningrad during World War II and was scrapped after she was salvaged in 1950. ==Design and description== The ''Pervenents''-class ironclads were designed as Coastal defence ships to protect the approaches to Saint Petersburg and were referred to as "self-propelled armored floating batteries". As such, a heavy armament and protection were the most important factors in their design. ''Ne Tron Menia'' means ''Touch Me Not'' and refers to the Biblical verse, John 20:17.〔McLaughlin, pp. 115, 127〕 ''Ne Tron Menia'' was long overall, with a beam of and a designed draft of . She displaced and her iron hull had a pronounced tumblehome. She was fitted with large rams at bow and stern; the stern ram also serving to protect her rudder and propeller.〔McLaughlin, p. 117〕 The ship did not steer well and had "an unpredictable habit of suddenly lurching to one side or another", probably as a result of poor water flow to the rudder. ''Ne Tron Menia'' required six men to man her wheel〔McLaughlin, p. 119〕 and her total crew numbered 459 officers and enlisted men.〔 She received the refurbished engine from the steam ship of the line as a cost-cutting measure, originally intended for her sister . This was probably a direct-acting steam engine and was built by the British firm of Humphrys & Tennant. Steam was provided by four rectangular fire-tube boilers. During sea trials on 18 July 1865, the engine produced a total of and gave the ship a maximum speed of . She carried a maximum of of coal, but her endurance is unknown. ''Ne Tron Menia'' was schooner-rigged with three iron masts. Under a combination of sail and steam the ship could reach a speed of 〔McLaughlin, pp. 117, 124–26〕 ''Ne Tron Menia'' was completed with seventeen rifled guns. Fifteen were mounted on the broadside on the main deck and two guns were placed in pivot mounts on the upper deck to serve as chase guns. One of the main deck guns was removed and a 60-pounder smoothbore gun was added on the upper deck in 1868.〔McLaughlin, pp. 120, 122〕 Unlike ''Pervenets'', the ship's tumblehome of 27°, intended to deflect shells, began above the waterline so the narrow vertical strake of wrought iron armor at the waterline was increased to a thickness of in compensation for its reduced protective abilities. The rest of the ship's side was protected with 4.5 inches of armor that reduced to beginning from the ship's ends. It backed by of teak and extended below the waterline. The ship's hull was divided by six watertight transverse and two longitudinal bulkheads for protection against underwater damage. The open-topped conning tower was also protected by 4.5 inches of armor.〔McLaughlin, pp. 122, 124〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Russian ironclad Ne Tron Menia」の詳細全文を読む スポンサード リンク
