Ships in class
On August 22, 2007, the Japanese Maritime Self Defense Force launched the Hyuga
, a new, large, flat deck vessel which had been laid down in May of 2006. The vessel is scheduled for commissioning in 2009.
This vessel has a large, flat-deck, and has been designated as a DDH, or helicopter carrying destroyer, for political purposes. The Japanese will build two vessels and they will replace two of the current, traditional DDH vessels in two of the JMSDF escort flotillas. It is contemplated that the JMSDF will then order two more such vessels to replace their other two DDH once these first two are commissioned into the fleet.
The Japanese currently list the carrying capabilitiy of these vessels as 4 small ASW helos or up to 11 large Chinook helicopters. Clearly, if capabnle of carrying 11 Chinooks, the carriers will be able to operate qutie a few more small helicopters, probably 18-24.
In addition to their aircraft carrying capabilities the vessels will have extensive command and control and communications capabilities to allow them to function as flagships and command ships for the other vessels in their flotillas. In addition, with modern Phased Array Radars (PARS), an integrated combat system, a 16 cell VLS carrying 64 Evolved Sea Sparrow anti-air missiles, and with two 20mm Phalanx CIWS, the vessels will be very capable of defending themselves against air attacks
