Editing Japanese battleship Musashi (section)

==Design and description==
{{Main|Yamato-class battleship}}
Since the IJN anticipated it would be unable to produce as many ships as the United States, the ''Yamato''-class ships with their great size and heavy armament were designed to be individually superior to American battleships.<ref>Garzke & Dulin, p. 45</ref> ''Musashi'' had a length of {{convert|244|m|ftin|sigfig=3}} [[Length between perpendiculars|between perpendiculars]] and {{convert|263|m|ftin}} [[length overall|overall]]. She had a [[waterline]] [[beam (nautical)|beam]] of {{convert|38.9|m|ftin}} and a [[draft (ship)|draught]] of {{convert|10.86|m|ftin}} at [[deep load]].<ref name=s10>Skulski, p. 10</ref> She [[displacement (ship)|displaced]] {{convert|64000|LT|t|lk=on}} at [[Standard displacement#Standard displacement|standard load]] and {{convert|71659|LT|t}} at deep load. Her crew consisted of 2,500 officers and [[naval rating|ratings]] in 1942, and about 2,800 in 1944.<ref name=j8>Jentschura, Jung & Mickel, p. 38</ref>

The battleship had four sets of [[Imperial Japanese Navy Technical Department|Kampon]] geared [[steam turbine]]s, each of which drove one propeller shaft. The turbines were designed to produce a total of {{convert|150000|shp|lk=on}}, using steam provided by 12 Kampon [[water-tube boiler]]s, giving the ship a maximum speed of {{convert|27.5|kn|lk=in}}. She had a stowage capacity of {{convert|6300|LT|t}} of [[fuel oil]], giving a range of {{convert|7200|nmi|lk=in}} at a speed of {{convert|16|kn}}.<ref name=j8/>

===Armament===

''Musashi''{{'}}s [[main battery]] consisted of nine 45-[[caliber (artillery)|calibre]] [[40 cm/45 Type 94|460-milliimetre Type 94]] guns mounted in three triple gun turrets, numbered from front to rear. The guns had a rate of fire of 1.5 to 2 rounds per minute.<ref name=c8>Sturton, p. 178</ref> The ship's [[secondary armament|secondary battery]] consisted of twelve 60-calibre [[15.5 cm/60 3rd Year Type naval gun|155-millimetre 3rd Year Type guns]] mounted in four triple turrets, one each fore and aft of the [[superstructure]] and one on each side [[amidships]]. These had become available once the ''Mogami''-class cruisers were rearmed with [[20 cm/50 3rd Year Type naval gun|{{convert|200|mm|adj=on}}]] guns.<ref>Garzke & Dulin, pp. 91–92</ref> Heavy [[anti-aircraft warfare|anti-aircraft defence]] was provided by a dozen 40-calibre [[  12.7 cm/40 Type 89 naval gun|127-millimetre (5&nbsp;in) Type 89]] [[dual-purpose gun]]s in six twin turrets, three on each side of the superstructure. ''Musashi'' also carried thirty-six [[Type 96 25 mm AT/AA Gun|25-millimetre (1&nbsp;in) Type 96]] light [[Anti-aircraft gun|anti-aircraft (AA) guns]] in 12 triple-gun mounts, all mounted on the superstructure.<ref name=s20>Skulski, p. 20</ref> The ship was also provided with two twin mounts for the [[licence-built]] [[13.2 mm Hotchkiss machine gun|{{convert|13.2|mm|adj=on}} Type 93]] anti-aircraft [[machine gun]]s, one on each side of the [[bridge (nautical)|bridge]].<ref name=c8/>

While the ship was under repair in April 1944, the two 155&nbsp;mm [[wing turret]]s were removed and replaced with three triple 25&nbsp;mm gun mounts each. A total of sixteen triple 25&nbsp;mm mounts and twenty-five single mounts were added at that time, giving the ship a light AA armament of 115 guns.<ref name=cfrecord/>

===Armour===
[[File:Musashi,Bridge.jpg|thumb|''Musashi's'' bridge in August 1942]]
The ship's waterline [[belt armor|armour belt]] was identical to {{ship|Japanese battleship|Yamato||2}}'s at {{convert|410|mm|in|1}} thick and angled outwards 20 degrees at the top.<ref name="USNTMJ">{{cite web|last1=US Naval Technical Mission to Japan|title=Ship and Related Targets: Reports of Damage to Japanese Warships|url=http://www.fischer-tropsch.org/primary_documents/gvt_reports/USNAVY/USNTMJ%20Reports/USNTMJ-200H-0745-0786%20Report%20S-06-2.pdf|website=fischer-tropsch.org|publisher=United States Navy|access-date=26 December 2016|url-status=dead|archive-url=https://web.archive.org/web/20131018053426/http://www.fischer-tropsch.org/primary_documents/gvt_reports/USNAVY/USNTMJ%20Reports/USNTMJ-200H-0745-0786%20Report%20S-06-2.pdf|archive-date=18 October 2013}}</ref> Below it was a [[strake]] of armour that ranged in thickness from {{convert|270|to|200|mm|in|1}} over the [[magazine (artillery)#Naval magazines|magazines]] and machinery spaces, respectively; it tapered to a thickness of {{convert|75|mm|in|1}} at its bottom edge. The [[deck (ship)|deck]] armour ranged in thickness from {{convert|230|to|200|mm|in|1}}. The turrets were protected with an armour plate {{convert|650|mm|in|1}} thick on the face, {{convert|250|mm|in|1}} on the sides, and 270 millimetres on the roof. The [[barbette]]s of the turrets were protected by armour {{convert|560|to|280|mm|in|1}} thick, and the turrets of the 155&nbsp;mm guns were protected by {{convert|50|mm|in|1|adj=on}} armour plates. The sides of the [[conning tower]] were {{convert|500|mm|in|1}} thick and its roof was 200 millimetres thick. Underneath the magazines were {{convert|50|to|80|mm|in|1|adj=on}} armour plates to protect the ship from [[naval mine|mine]] damage. ''Musashi'' contained 1,147 watertight compartments (1,065 underneath the armour deck, 82 above) to preserve [[buoyancy]] in the event of battle damage.<ref>Garzke & Dulin, pp. 100, 104, 122</ref>

===Aircraft===
''Musashi'' was fitted with two [[aircraft catapult|catapults]] on her [[quarterdeck]] and could stow up to seven [[floatplane]]s in her below-decks [[hangar]]. The ship operated [[Mitsubishi F1M]] [[biplane]]s and [[Aichi E13A]]1 monoplanes and used a {{convert|6|t|LT|adj=on}}, stern-mounted [[crane (machine)|crane]] for recovery.<ref>Skulski, pp. 25–26</ref>

===Fire control and sensors===
The ship was equipped with four {{convert|15|m|ftin|adj=on}} [[Rangefinding telemeter|rangefinder]]s, one atop her forward superstructure and one in each of her main gun turrets, and another {{convert|10|m|ftin|adj=on}} unit atop her rear superstructure. Each {{convert|15.5|cm|adj=on}} gun turret was equipped with an {{convert|8|m|ftin|adj=on}} rangefinder. Low-angle fire was controlled by two Type 98 [[fire-control director]]s mounted above the rangefinders on the superstructure. Type 94 high-angle directors controlled the 127&nbsp;mm AA guns, with Type 95 short-range directors for the 25&nbsp;mm AA guns.<ref>Skulski, pp. 20–21</ref>

''Musashi'' was built with a Type 0 [[hydrophone]] system in her bow, usable only while stationary or at low speed.<ref>Skulski, p. 21</ref> In September 1942, a [[List of Japanese World War II radar#Shipborne radar|Type 21 air-search radar]] was installed on the roof of the 15-metre rangefinder at the top of the forward superstructure. Two Type 22 surface-search radars were installed on the forward superstructure in July 1943. During repairs in April 1944, the Type 21 radar was replaced by a more modern version, and a Type 13 [[early-warning radar]] was also fitted.<ref name=cfrecord>Hackett & Kingsepp</ref>
