Description
Japan unveiled for the first time August 2013 the Izumo (DDH-183), Japan Maritime Self Defense Force's (JMSDF) future helicopter destroyer which will become the flagship of its fleet. First of the 22DDH class, the Japanese Navy Izumo is the largest warship built by Japan since World War II. The 248-meter-long and 19,500-ton helicopter carrier named Izumo is still under construction in Yokohama and is set to be commissioned into service in 2015.

Once commissioned, the ship will initially deploy with nine helicopters (7 SH-60J or SH-60K ASW Helicopters and 2 UH-60J SAR Helicopters) despite the large size of the flight deck and hangar. Many experts speculate that 22DDH type vessels may already be able to accomodate VSTOL platforms such as the F-35B and V-22 Osprey given the large nature of the ships, especially when compared to the existing Hyuga class vessels.
