This destroyer paper model is from Japan Maritime Self-Defense Force, and it is designed by masayui.
The Hyūga-class helicopter destroyer are a type of helicopter carrier being built for the Japan Maritime Self-Defense Force (JMSDF). Two ships of the class were built to replace the two 7,000-ton Haruna-class helicopter destroyers. The new ships are the largest combatant ship operated by Japan since the Imperial Japanese Navy was superseded by the JMSDF. The first ship in the class, Hyūga, was commissioned on March 18, 2009 and stationed in Yokosuka, near Tokyo. The second ship Ise went into service on March 16, 2011 and will be stationed in Kure.
The Hyūga-class' specifications are comparable to light aircraft carriers, such as Italian Giuseppe Garibaldi, Spanish Principe de Asturias and Royal Navy's Invincible-class carriers. Under the JMSDF's naming conventions, the ships are called Goei-kan in Japanese and destroyer in English, as same as all the other combatant ships of JMSDF.
According to a PBS documentary, JS is the "first Japanese aircraft carrier built since WWII."
The Hyuga 's code-name (16DDH) and Ise 's code-name (18DDH) derive from the Japanese calendar, specifically the 16th year and 18th year of the Heisei reign (2004 and 2006), when the provisional title was given.
