    Japanese Hyūga-class Helicopter Destroyers

    The Japanes Navy, or to be politically correct, Japan Maritime Self-Defense Force (JMSDF) commissioned a Helicoptier carrier Hyūga (Pennant DDH-181) in March of this year. They are planning to add at least one more ship of the same class at some future date.

    They are of similar size to the Royal Navy Invincible Class





    • Displacement: 13,500 tons standard;
      18,000 tons full load

      Length: 197 m

      Beam: 33 m

      Draft: 7 m

      Propulsion: COGAG, two shafts, 100,000 hp

      Speed: 30+ knots (56 km/h)

      Crew Complement: 347

      Armament: 16 cells Mk 41 VLS
      16 ESSM
      12 ASROC
      2 × 20 mm Phalanx CIWS
      2 × triple 324 mm torpedo tubes
      12.7mm MG

      Aircraft: 3 × SH-60K
      1 × MCH-101
      Up to 11

      Manufacturer: IHI Marine United





    The JMSDF fleet is actually quite formidable and is continuing to grow in size under the radar so to speak as a counter to the ever growing Chinese Navy.


    All Japanese ship classes:

    • DDH: Destroyer Helicopter

      DDF: Guided Missile Destroyer

      DD: Destroyer

      DE: Destroyer Escort

      SS: Submarine

    Note that each cell on a Mk 41 VLS can carry 4 ESSM missiles, so they could increase the numbers of SAMs to 64 if ASROC wasn't carried.

    There seems to be a quiet growth in large helcopter platforms over the last few years, Korea has the Dokdo at 14,340 tons (loaded displacement: 18,860 tons), with 3-4 units expected.

    Simply put, the entire world understands the importance of using helicopters for disaster relief work. The one exception is the Irish naval service.

    Japan is forbidden by treaty from operating Aircraft Carriers. Hence the name"Helicopter Destroyer".

    How many helicopters do the Irish Air Corps operate? There are more medivac helicopters in many cities throughout America.

    You shouldn't give up just because the last time Ireland chose too small a boat, and chose an underpowered helicopter. There are bigger boats and more powerful helicopters.

    If its too technically challenging, I suggest you start first with your education system.

    That you for that pearl of wisdom. It is of course entirely down to the Naval Service that it, as a small force operating mainly in the fisheries protection role, has never managed to swing a quadrupling of its funding to fund these endeavours and fundamentaly change national security policy with regard to the deployment of assets abroad.

    And there we all were, labouring under the illusion that, somehow, the nature of the political attitude to defence spending, the general small scale of the Defence Forces, and indeed the almost complete lack of a naval tradition in this state had something to do with the relative size and equipment of the NS.

    Thank you so much for enlightening us all. Really.

    lets see where do I start......

    It has nothing to do with education etc...its money! Nothing else but money!

    We are not a nation who needs a large armed force as we are not at war with large portions of the world at any given time nor have we ammassed enough enimies who want to wipe us of the face of the earth that we have to spend a large proportion of the nations GNP on vast armies and navies to defend ourselves.

    The Naval Service even gave your own Service lesson on how to operate the machines from similar sized ships.

    We could operate the helos you do from the ships you do if we had your money and resources and often total disregard for human life.

    I'm sure there are cities in the US that have double our entire AC fleet and ships as large as small towns here... but size ain't everything.
    Lets look at the country that threw oney at projects like the V22 Osprey over the last 25 years and it still isn't right

    Invaded a country on the pre text of weapons of mass destruction that never existed.....

    Spent thirty years fighting a war which was 100 years old in SE Asia and still lost with all the weapons in the world to draw on

    Fought a war in Korea with a third world nation and still only managed a draw.

    Spent the last 7 years spending billions of dollars a day looking for one man and invaded two countries on the pre text

    while a large percentage of your own population are living below internationally recognised poverty levels.


    And you call us uneducated.........definetely watching too much CNN
    Time for another break I think......

    Completely unrelated of course is the mention in the tenders for the EPV for a helipad, and the OPV to be able to operate UAVs.

    Of course would it be easier to throw 200 odd million at one great white hope to replace the vintage antiquated fleet of the USCG, and then realise as she is being handed over that, well, most of her sensors don't work proper, but hey, why not take it anyway, and let the customer sort out the problems...

    So sort out your own problems before you try ours.

    We still have a HPV with an operational helipad.
    However, as mentioned many millions of times here, it became impractical to operate the Heli from it.

    We no longer have Naval helis, I'll give you that.

    However we do have a fixed wing maritime patrol aircraft that was so fantastic at its job that the USCG decided it wanted it too.

    In fact, if there was respect and tolerance shown to these same countries from the outset, would there be as as many 'Bin Laden's' running around today? I don't think so.

    When will these men in power realise that if you jump all over people, they will respond in a negative fashion.

    Wake up Mr. Bush and others in power, get a grip!

    Well, there is one ray of light on the horizon, in that there is now an opportunity for real change. My gut feeling is that the American people will get an administration that will pull back from the brink of wars and work for the betterment of human kind. And in doing so will set an example for the rest of the world.

    I am siting on the edge of my seat in expectation.

    Sea Toby is what is reffered to in 'The Guardian 'as a' puddle pirate...'

    In 1986 we had some of the same visit us on the L.E. Eithne to see how were operated with helos from small ships....
    Hence the Dolphin..

    Now back to the Bertwolf fiasco..you buy a 465 million dollar vessel and accept it as unfinished and nobody wants to set up comms with you as the comms are all flawed.

    This is the newest vessel in the USCG and a 40 year average is the norm with the newer stuff all older than 20 years and nothing bigger than the David F{ google it)

    Yes ST maybe we could go back to education standards and maybe the USCG could be in the remedial class.
    We'll set the standards..you can follow.

    They're also forbidden by the Constitution from having an Army, Navy and Air Force.

    Just call it something else, you'll be good to go. It'll be a fixed-wing-capable anti-submarine air-operations cruiser or something equally stupid. Either way, it's fitted for VSTOL should they buy some.

    The Invincible-class were once called "through deck cruisers" and the Kuznetsov a "heavy aircraft carrying cruiser" (well it does carry more than 1,000 SAMs).
