Type 075 LHD discussion

Bltizo said:

Ships with gas turbines tend to run more efficiently at 30+ knots, and carriers tend to conduct operations at about 30 knots with reserve speeds being even higher.

In relation to ships like 075 (other LHDs, LPDs etc) they only tend to be able to do 20+ish knots as their top speed. The Hyuga and Izumo classes are the exception.

I think it's more accurate to say that gas turbines run more efficient at full output.

But much of the time, ships like the Arleigh Burkes only have 1 gas turbine in operation, with the other 3 switched off.

(2048 x 1162)

The blurred module on the right of the first type 075 is the second type 075?

Why are these indoor assembly halls built so closely together? Do they have doors on all sides for easy movement of built modules?

And is it me or do the modules marked as 1, 2 & 3 are wider than the ship so far assembled?

That shipyard is really busy

With 8 x LPD delivered which btw took 17 years these 3 x LHD are so much faster

No doubt HD can build fast

They launched a LPD within 6 month intervals in the end last few units

And I think they can do same again

It would make sense. Have a bit of overhang on the port side to balance out the weight of the island on the starboard side. Japans Hyuga and Izumo classes are similar. Probably a few other LHA classes i cant think of too.

Quite the same width I think, look at the green dashes I have drawn:



So the three modules may be part of the first LHD, not the beginning of the construction of the second ship.



And three positions for three missing modules on the ship so far assembled:

What will most likely be the purpose of the Type 075's air wing ? Anti-sub or airborne operations ?

As type 075's class designation indicate, it is a LHD (Landing ship Helicopter Dock), the primary role of it's air wind is to transport personnel and materials to shore. Two primary air wings would be (1) Z8 and Z20 transport helicopters and (2) Z10 attack helicopters.

Therefore the answer is simple, the main purpose is to use its air wing to send soldiers and light equipment to shore to support an amphibious assault operation, and to provide low level air support to the troops on shore.

Anti-sub helicopters may be stationed onboard, but their primary role is defence against submarine attack rather than hunting enemy submarine. To hunt a submarines your ship must have speed to chase after them, sub hunting may take hours or days, if you haven't sink the sub after 24 hours and you do not have the speed to chase after them, they will have escape beyond your helicopters' range.

So for a low speed LHD, their anti-sub helicopters are mainly for self defence, certainly not primary role of the main air wing.

Isn't LHD a USN designation ? It doesn't really make sense to use this classification when you don't know what the ship will finally be (or will even looks like). In fact this tread classifies the class as an LHD, a LHA and an LPH.

Maybe a better solution would be to see it's Chinese classification, if the chineses use one.
