PLAN Anti-Piracy Deployments

You can probably cram as many helos as you want but that isn't really the point, we are talking about simultaneously operating 3 x Z8 class medium lift helos which can carry say 25 troops



The first solid white line from the aft position is around 22 metres from the back of the vessel, pretty clear cus the Z8 is probably bang on the line or jus behind it, makes sense since its around 23m long

The second line the one in the middle, that is the dashed white one is shorter, around 18 metres from the first solid line, so it can't take a Z8 maybe a Z9 yes no problem

Then the 3rd solid white line is again 22 metres so it can take a Z8, however the 3rd helo the one closest to the hanger can be brought forward easily by 3-5 metres to make the space in the middle to be also ~22m to accommodate a Z8

Main point is that the 3rd helo can be brought forward because there is actually another 10m of space which is unmarked, yeah there's crane on the side but it's not in the way, you would only need to bring the 3rd helo (one closest to the hanger) forward by few metres really, here's a picture from inside the hanger looking out

Again I think it's PLAN who is being way to conservative with its operations, there's no question three Z8 can operate off the deck together, that's 75 marines in a single wave

we've seen 2 Z-8 and 1 Z-9 on the deck at the same time.

Japan's new Izumo "destroyer' (lol) is 248m long and operates 5 helicopters, so 2 for the 071 LPD is about right. .

Well, yes, but that is all part of the JMSDF game of understating the capabilities of this vessel. Although five landing sport are painted on it, when you compare the space available, it is clear they could operate 8 at once if they wanted.

Here's how the deck layout is shown:


Here's a Wasp Class deck, which is only 30 ft longer:


Now, using the same seperation that the JMSDF shows for the five, here's how they could make use of it for eight.


So, I believe it safe to say that ther Izumo was designed to do a lot more than what they are talking about...including the overall numbers of aircraft. The hanger on the Izumo is a LOT larger than that of the Wasp and is very close to the hanger size on the USS America LHA...whch can hold over 30 aircraft.

Yes Wasp has the well deck which takes out lots of space

Jeff what's the dimension of the hanger for the Izumo, if we are talking exclusively helos how many do you think they can get into that hanger

Secondly if we mix the helos with the F35B what is the number of F35B?

The hanger on the Izumo is 550 feet long, and 80 feet wide. It is approximately the same size (a little smaller) as the hanger on the new America LHA-6, which was designed to be aircraft centric and specifically to handle the MV-22 Opsrey and F-35B JSF.

I expect the Izumo could carry 18 or more F-35Bs if it were dedicated to the Sea Control role with only 4 helos. Otherwise, probably 12 JSFs and 12-18 helos.

The Japanese are indicating nine to eleven helos...which is obviously far understated.

I wouldn't want to land my helicopter nearer to the hangar. You have to think about the way the air flows about the ship's superstructure. Nearer the hangar turbulence will be too great a problem.

Actually I just had a question. How are big helos moved about on LPD/LHD deck? Do they need a tractor to pull them?

I hope this answers your question. I have however seen a few times where if a helo needs to be move just a couple feet a bunch of guys can push/pul em w/o the need for the tow tractor.

The reason I asked is because I remember people are really interested in the vehicle on the Liaoning for towing aircraft. But they must have similar vehicles before for the 071 LPD to get large helos like the Z-8 into the hangars, so wondering if they are the same or the ones for helo can be smaller.

you can't really compare a LPD to a LHA or even a carrier. Biggest difference is an LPD generally do not have below deck aircraft hangers. There is less on deck maneuvering of aircraft. LPD's also do not have an open deck. They also do not have to compete with non rotary aircraft unlike a carrier or LHA. Generally speaking, with an LPD as long as there is big enough clearance for a helo to land it's good enough. On a carrier or even a LHA with STOVL aricrafts you obviously can't just park a helo anywhere you want and leave it there unless you want some spectacular crash!!
