Details of the propulsion system for the new Helicopter Carrier of the Japanese Navy / Maritime Self-Defence Force (JMSDF) have been announced. To be built by IHI of Tokyo, the LOA 814 ft (248 m) and beam of 124 ft (38 m) vessel will have a fully loaded displacement of around 27,500 tons. The official Japanese 22DDH designation of the ship is of a “destroyer” but in reality it is a helicopter carrier. The reason for the diplomatic designation lies in the post World War 2 constitution which prohibits Japan to own aircraft carriers.

Japan already has two smaller Hyuga Class helicopter carriers of 18,000 tons full displacement and the new ship will become the largest vessels in the Japanese Navy.

The propulsion system comprises four GE LM2500 gas turbines of 33,600 hp (25 MW) each giving a total power of around 135,000 hp (100 MW) in a COGAG arrangement giving a speed of 30 kt. The ships will also be using GE’s smaller turbine, the LM500 with an output of approximately 6,000 hp (4.5MW)  in a turbo-electric configuration for on board power generation.

The turbines will be built by GE licensee IHI with a delivery date of late 2012 for the LM500s and early 2013 for the LM2500 engines.

The LM2500 and LM500 gas turbines have been in service on a number of other ships of the JMSDF. LM2500s presently power the Hyuga helicopter carrier class, the destroyer classes Atago , Takanami, Murasame and Kongou:  LM500 are in service on the Hayabusa class patrol boats and Sparviero fast attack class hydrofoils.

It looks like they used destroyer parts at least.... the superstructure looks like it was cut-and-pasted from a US Arleigh Burke (DDG-51 class).
