Besides, and I'm a little confused here, why would Japan's territorial claims (i.e. the Senkakus) be out of range of the JASDF? They have squadrons based in Okinawa, a bit over 400km away. Why isn't that enough to protect the MSDF in that area?
As well as the Senkaku islands, there's a dispute over some godforsaken rocks half way between Taiwan & Guam called Okinotori.

I think the thread is going a bit off topic. It's about the 13,500 ton destoyer.

But any way, I think in East Asia, things will be in the funny way for while. Japan has been having these huge destroyers and frigates for quite a while. And china will launch her large peace loving training ship very soon. It actually shows the delicate situation here, but it's definitely escalating. (I have to say for the last many decades, China had nothing to respond to Japan's super navy.) The problem now is that the evil china actually responded with a larger "non-carrier" ship, what should every body do next?

I see these destroyers as operating a range of UAVs into the next decade as well. One of these Destroyers with a Aegis Destroyer and associated units will be deploying UAVs that will be giving the group a battle space situaltional awareness. Hunting for subs, surface units and even a AEW capability.

I agree with a comment above if the Japanese Navy wants to deploy a carrier, thats what they will build.

It is both, the idea I'm expressing is in regard to what purpose they are to be for JMSDF which consideres itself a "defense force". Why do they need 13,500 ton helicopter destroyers which are clearly offensive ships for defensive purposes. Japan's only possible enemy with a significant navy is China and I fail to see how 30 ASW helicopters would be of any impact to a large surface fleet.

This message I pasted hereabove is basically a typical misplaced comment.
Either the author misunderstand the real motives of JMSDF, or he wants to make that sound ugly bad guys.


Mod edit: HOW exactly does this lack of understanding make him racist? If he posts something racist it'll be deleted and he'll be banned. Simple as that. I don't thinks he's done that yet. You can message webs if you still have a problem with it.

Yeah, theres something like 3-4 soldiers stationed on survelience to ensure its not invaded, that posting has gotta suck as they are the only ones there.

This destroyer that they are building(sorry to get bak on topic:D ), it seems like a small landing platform with a missile launcher, this would seem to be a LHD. But with japan not needing to invade anything, it would be useless, hence destroyer. With the idea of F-35B This goes back to the argument of a
adequite air coverage from a converted LHD and use. This is way to small to protect any sort of fleet, or mound of rocks for that matter. A ski jump conversion would be pointless, let alone the space needed to carry enough F-35Bs while operating continous air coverage, enough fuel, supplies and so on.
Theres curretly a big push in Japan for dropping of Article 9, which would see perhaps many of their ships being relabelled if succesful?:D

Does japan have any form of attack...sry sry, defence helicopter, in way of Apache, cobra?

It's not an LHD, as it doesn't have a floodable dock (the D is for Dock). But Japan does have some amphibious assault ships - the 3 Osumi-class. The 16DDH doesn't seem to have accomodation for troops, but seems to be well-equipped as a flagship, & to support helicopter operations both by itself & by accompanying ships, with the potential, perhaps, to be converted to STOVL operations. Note the "perhaps". How big are the lifts, & how much weight will they take? Are they compatible with F-35B? What about deck construction? Could it handle take-offs & landings?

It looks as if it could easily operate Harriers, but that doesn't matter, since the Harrier is out of production, & there's no supply of sound second hand Harriers.

Japan operates AH-64 & AH-1.

Yeah, shoulda said LHP. but anyway, i would love to know how they passed a Grade A Assault helo like the AH-64 through Article 9, not exactly a good way of saying defence with a high speed Attack chopper.

Anyway, the reason i asked was that this "destroyer" could be a staging post for attack choppers if article 9 was dropped, and could be well used in covering any invasion force. As for defending Japan, i fail to see the true need for a DDH, what is the point of having 3 helo's launching if its to block enemy invasion or rescue people, would'nt a LHP such as the San Antonio or even the new dutch CSS, would go better in service with the JSDF.

The whole DDH seems a little, pointless perhaps? Can someone give me a real use and reason, keeping in mind Japan is pacifist and can not attack a dove let alone a country. Even to stop military power to Sth Korea or even china, it just seems like with all their construction of AWDs and such, this is a little out of place. If this is a first step towards japan realising their goal of an aircraft carrier, then they will tread carefully, but keep in mind, it will all be worthless if they still have article 9(my views on this are confusing, and political so i'll avoid it:cool: )
Just to note, "There has never been a destroyer that exceeded 10,000 tons".

The AH-64, & before them the AH-1, were bought to blat invading tanks, & perhaps landing craft (a Hellfire would do that quite well - and Japan developed its own heavy "anti-tank" missile which was issued to coast defence units for exactly that purpose). As for the 16DDH, I think the real reason is for helicopter ops, particularly anti-submarine but also anti-ship & anti-mine, & flagships. Japan has a strong interest in sea control, being utterly dependent on seaborne trade for raw materials, particularly fuel & food. You lot down there, with your ample food, coal, iron ore, etc*., can afford to be a bit relaxed about such things, but not Japan. They're thinking less in terms of the Red Army coming in from the north, nowadays, & more in terms of Chinese submarines. Lots of Japanese islands, very strung out. Count the sea between Japanese islands & it suddenly becomes a huge country.

The Kongos have awesome air-defence capabilities (Aegis with 90 VLS cells), but can't sustain helicopter ops. These will make good partners for them, & can lead an ASW or sea control flotilla of a Kongo or two & several smaller vessels.

If Japan was attacked, how could it protect itself without such versatile platforms? Article 9 in its current state would technically imply that the SDF cannot exist in any form, so obviously there is room for interpretation. No one, except perhaps people that wish Japan harm (not implying you), would say that it cannot have crucial equipment like attack helicopters when they could be very necessary in a time of war.

As for defending Japan, i fail to see the true need for a DDH, what is the point of having 3 helo's launching if its to block enemy invasion or rescue people
3 is the official number - in reality it could carry nine or perhaps even more.

Even to stop military power to Sth Korea or even china, it just seems like with all their construction of AWDs and such, this is a little out of place.
As I have tirelessly pointed out, China is committed to greatly modernising its submarine force, while maintaining large numbers of them. This project will help ensure that Japan can counter this threat if necessary. Without it, when the Haruna class is retired over the next several years, Japan would be severely limited in the helicopter-born anti-submarine operations it could undertake.

Just to note, "There has never been a destroyer that exceeded 10,000 tons".
Plenty of countries have fiddled definitions to suit themselves. We had "through deck cruisers"; the Russians had "aircraft carrying cruisers". Japan isn't doing anything new.

See, i just rekon the range would be smaller compard to, say, an orion operating from Japanese base . A helo might sound good and all, but having as has been pointed out, 9, you've still got me as to why they need 9 for one or two damn subs. unless the enemy tactic is to swarm Kriegsmarine style the japanese oceans this seems like an awful waste.
And while on ASW, thats why i mentioned the CSS, thats a role it can operate in(and i ment danish, not dutch, although i believe they do have CSS.) The flyvefisken-go on, pronounce it!- class multi roles are for anti-surface/anti-submarine, anti-mine, and survellience.:ar15
And lets not forget, we rely on japan for our Tvs and playstations, without, we'd be lost, and i'm not kidding here!
And since when has mudgee made wine, jeez they'll let anyone do it these days. :D

Flyvefisken is easy when you're part Danish. :) But Flying Fish aren't intended to operate as far from home, commanding a fleet. They're small country ships, jacks of all trades because they have to be. Japan can build ships to do all roles.

An Orion from a land base a long way away won't have the endurance or reaction time of helicopters on a ship near , & can't escort tankers from the Straits of Malacca.

And what's wrong with those on the other side of the Great Divide from you lot making wine? They've got to do something out there in the wilds. Very hospitable people, actually. I won the cricket club raffle in a local pub (we only bought tickets to be polite), & the locals were fine with it. Won a slab - my pick of what they had. :) Then we went to the town disco, where I was doing very well with a local young lady until one of my bloody colleagues (who'd drunk too much) decided to protect her compatriot (who didn't want protecting) from the randy Englishman & butted in. :(

We'd really need somebody from Japan in this internet site ;)

My position remains that this 13,000 tonne "destroyer" is a helicopter carrier such as the British Ocean, same size, though faster and with better self-defence capabilities.
There are only 2 options :
> either the ship will be an illogically big platform for approx 10 big ASW helos, and that's it...
> or the ship is used as a complement to the Osumis to support overseas missions. In this case it can house several helos (not only ASW) and it would make huge sense to add F35Bs. The lifts are certainly big enough, though I don't have any data about the flight deck's suitability for vertical landing of a F35B. By the way, V22 Ospreys would be perfect aboard this ship:D

16DDH (DDH-13500) will be vessels in the same category of Garibaldi was before she received her Harriers. An helicopter carrier with a powerful weapon & sensor suite by itself. Like some other explaines above, a capable ASW, MCM & command ship. In JMSDF doctrine they would be the capital ships of a destroyer squadron in the same way that present DDH do.
May be in the future they could operate F-35B but aren´t the ideal vessel to do so. Only the aft elevator seems sized for F-35B (20 x 13 m), the other is some smaller (20 x 11 m). Hangar is capable up to eleven helos (a mix of Seahawk & Merlins). It's a beat bigger than the Garibaldi one but I think that only 6-7 F-35B could be fitted into in a "confortable" way.
Probably they will be capable of carry some troops but they aren´t an anphib like the Oshumis (at best a part time LPH?). Anyway, they have a ro-ro door in starboard side, I suppose in order to fit some equipment directly to the hangar deck.
Remember that they'll have a 4 faced "APAR" system (¿FCS-3?), 2 MK-41 modules for up to 64 ESSM and a pretty impressive sensor suite.

I still fail to see the point of an LHP for their navy, if their all defensive, one would think that an amphibious assault platform would not be needed:ban , and even with the escort duties, anyone, anyone at all see 9 or 10 now, thats right 10, helos. we'll say 9.5 to be safe, as a little excessive, if its for escorts, i still rekon something smaller would work so so much better, cause you could, just think bout this for a moment, have 2-3 ships instead of 1 covering the AOR. think of the range on that.

The CSS could'nt be just for inshore defence, Denmarks not that bloody big to require 10. Plus don't they protect...greenland or iceland or snowland or something. gotta get from Denmark to that place^ Although, Jack of all trades, masters of none comes to mind.

Flyvefisken is easy when you're part Danish.
Ahh ha, very funny, ya got me there. Freaky deaky Danish is wat it is!
And those guys on other side of the divide can stay their, thats why its a divide, to keep the peace, and it was to keep out the POMs, but i guess the guards were asleep again. Come here stealing our jobs and women, lucky we're stealing yours at the same time, but not quite a fair trade if ya look at it.:girl ;)

Its my opinion the new Japanese helicopter destroyers are fleet flagships first, and ASW warships second. The flagships role is very similar to the American navy's Blue Ridge and Mount Whitney, with the Japanese adding ASW helicopters and the ASW roles. The American navy also operates old LSDs as fleet flagships, their helicopter decks and large berthing spaces are very useful. These Japanese destroyers fulfill the same role. The American navy may build a similar warship when the time comes to build new fleet flagships.

If the Japanese were to build an aircraft carrier, they would definitely build a proper one similar to the new British carriers.

1. It has been explained enough times. If you fail to understand then I can't help you any more. There's nothing wrong with having spare capacity, nor a vessel built to serve as a flagship as Toby said.

2. Don't use the "banned" emote like that. It's very rude.

We, the freaky deaky Danes, use 3,500 tonne OPV's with icebreaking capabilities for patrolling Greenland, the Faroes and Snowland. :D

Flyvefisken just don't have the seakeeping and endurance for that kind of work. It's a 450 tonne plastic cup that's half missiles.


On topic: I agree that this DDH is for sea control, as a command platform, and will match the Kongo's well.

It isn't an amphibious assault platform. It lacks the cargo & troop space for that. It's fast, pointy-ended, & loaded for bear. But Japan does have some amphibious assault ships (the Osumi-class), & that's fair enough, for a country consisting entirely of islands. Defence requires the ability to retake lost bits. You can't defend every little island all the time.

This ship isn't an alternative to smaller ships, it's as well as them. As I pointed out in an earlier post, Japan has whole classes of ship equipped to carry but not support helicopters. They've been confined to home waters until now. This ship enables a flotilla of them, led by a 16DDH, to operate in the open ocean or on trade routes. The 16DDH can enable the smaller vessels to operate helicopters away from shore support, & can provide area air defence in most environments, as well as looking after itself. For somewhere really hairy, you send along a Kongo as well. Imagine one of these, as well as several smaller ships & maybe a Kongo, hunting subs - not one or two, but a big chunk of the PLA sub fleet - over tens of thousands of sq km of sea. The 16DDH would act as the flagship, comms relay, mother ship for the helicopters, etc., while the rest spread out, providing landing platforms for the helicopters & using their own sensors. That's one scenario. There are others.

If the job only needs one or two ships, then you send the GP or ASW destroyers or frigates which can support their own helicopters.

You bring up an interesting point here - are you sure about the ESSMs ? So far I've read of 16 VLS for Sea Sparrow. I don't doubt capability to upgrade, but I haven't read that the upgrade is coming soon.
Btw my question is valid for VLS on the other DDGs in the Japanese NSDF.
