Editing Java-class cruiser (section)

==Service history==
===''Java''===
After she was commissioned, ''Java'' sailed to the East Indies and visited several cities throughout [[East Asia]] and [[Oceania]]. In 1937, she returned to Europe to escort convoys through the [[Strait of Gibraltar]] during the [[Spanish Civil War]] and underwent a refit in 1938. By 1939, she continued to escort convoys in Asia before she joined an [[Allies of World War II|Allied]] fleet and participated in several attempts to repulse [[Dutch East Indies campaign|Japanese invasions of the East Indies]]. After several failed attacks, the cruiser was [[torpedo]]ed and sunk while attempting to prevent the [[Battle of Java (1942)|invasion of Java]] during the [[Battle of the Java Sea]].{{sfn|Whitley|1996|p=190-191}} Her outdated design proved fatal as she lacked modern protections and redundancies. She was struck by a Japanese torpedo on her stern, which caused her aft magazine to detonate. The resulting explosion ripped apart the ship, and she sank in about 15 minutes with most of her crew.{{sfn|Cox|2014|p=316-317}}

===''Sumatra''===
''Sumatra'' likewise operated with ''Java'' in the East Indies. Upon ''Java''{{'}}s return from her 1938 refit, ''Sumatra'' sailed to Europe where she also escorted convoys during the Spanish Civil War and served as a [[training ship]]. She was docked and awaited her own refit in May 1940 when [[Nazi Germany|Germany]] invaded the Netherlands. She then fled for the United Kingdom and was placed under the command of the [[Royal Navy|British Royal Navy]]. The next month, she sailed for Canada to evacuate members of the [[Monarchy of the Netherlands|Dutch Royal Family]] and later patrolled the [[Caribbean]] and [[Mid-Atlantic gap|mid-Atlantic]] for [[commerce raiding]]. Later that year, she returned to the East Indies, was retrofitted, and had her crew reassigned to other vessels. After war was declared against Japan, the cruiser fled Asia with only a portion of her crew and machinery online. She sailed around the world and arrived back to the United Kingdom. The Royal Navy viewed her as obsolete, and had her disarmed to replace worn-out weapons on other Dutch vessels and later had her sunk as a breakwater during the construction of an [[Mulberry harbours|artificial harbors]] after the [[Operation Overlord|Invasion of Normandy]].{{sfn|Whitley|1996|p=191}}{{Sfn|Willigenburg|2010|p=16,24}}
