The PLAN LCAC Type 726 Yuyi Class

I was contemplating the same. The current design could well be unsatisfactory due to the large dimensions of the engines relative to the craft, or perhaps even the engines' performance. Hopefully a redesign, if it's being considered, involves new and more (space) efficient engines, freeing up more cargo space, and perhaps even shrinking its width a bit because it barely clears the 071's well deck.

I don't think that is the problem though. They have vibration issue with the engine using the ukrainian engine But they have succeeding in manufacturing domestic engine Henri K wrote and extensive article
No as I conclusively proof Type 726 is not small It has volume to carry 2 IFV side by side. It can carry type 96 tank which is 50 ton
Now why it hasn't been shown with those load?

My guess is doctrinal don't forget that the production model is only now entering the service We still see them outfitting in Jiangnan shipyard Dec 2016 So still not 1 year with the new engine

When I say doctrinal they still hasn't figure out how to fit Yuyi in the overall scheme of amphibious assault. Thaw is why they don't train with load on
Don't forget that Chinese marine is still small 10000 and very young service They are in the process being augmented . Traditionally they are only task to storm Taiwan but now may get wider scope

Here is the article
The Chinese navy is in the process of reviving mass production of its equivalent of the US LCAC, the Type 726A , at the Jiangnan Changxing Shipyard in Shanghai, based on satellite images as of December 9, 2016.

Indeed, apart from the presence of two Type 055 destroyers and six Type 052D destroyers , two of them outside the artificial basin of production line 4, there are also two Type 726A in water and two Other on the ground ( in yellow frame ).

The first four of the Type 726 class , a priori endowed with Ukrainian gas turbines UGT-6000 ДМ71 (*), were produced at the same shipyard six years ago.

These 150-ton airplane landing craft designed to enter the raft of the Chinese Navy's Type 071 amphibious vessel would have encountered a number of technical problems that temporarily halted production, forcing the four Type 071 shifting more than 20,000 tons to limit their projection capabilities to only amphibious IFVs and helicopters, not combat tanks.

The most widespread rumors spoke of the concern to replace Ukrainian turbines with native ones, and also a problem of the steering system. But according to a source working at the shipyard in question, the problems were rather the low frequency vibration and also the loud noise.

The improved model and equipped with a Chinese propulsion, with the QC-70 gas turbine developed from the WS-10 aviation engine , seems to be called the Type 726A now.

Each Type 726 / Type 726A can carry up to 60 tonnes of payloads, the mass of a Chinese combat tank such as ZTZ-96A or ZTZ-99A. The distance is estimated at 320 km, sufficient to cross the Taiwan Strait at a speed of up to 80 kn, one way, if the sea situation is unknown.


In terms of development, it is interesting to note that the design of the Type 726 / Type 726A is not entirely realized by the players in the naval sector, but also by those of the Chinese aeronautical group AVIC.

For example, the assembly of the propeller fairing is made by the CAC (Chengdu Aircraft Corporation), a subsidiary of AVIC, which today produces J-10B and J-20 fighter jets .

And it is all the more surprising to note the presence of a little French touch in this Chinese LCAC - indeed, ACC, assisted by Nanjing University of Aeronautics and Astronautics, uses factory software Dassault Systemes, DELMIA, to plan and simulate a construction part related to the Type 726A.

To increase productivity and anticipate possible problems in the assembly of the fairing - which measures 4.7 meters in diameter and 1.9 meters in height, and weighing 1.3 tonnes in total - the Chinese engineers use the module DPE (DELMIA Process Engineer) for scheduling and scheduling operations, as well as DPM Assembly and Human modules, as a 3D interface, to simulate the editing sequence and ergonomics of the workstation.

The same software suite is used today in the assembly and installation of A350 aircraft.

It will also be interesting to know how these engineering and industrial data are managed, secured and shared in a cross-sector supply chain environment, between the avic group of the aeronautics sector and the CSSC group of the naval sector.

While waiting for the new Type 726A to be tested and delivered to the Chinese Navy, a recent video broadcast on local television shows that a new copy, registered 3332, entered service and participated in an amphibious landing exercise, Now only three Type 726 - registered 3319, 3320 and 3321 - have been seen.

Right. Fanbois "proving" nothing but hot air aside, space-efficient engines and design optimization will be key to opening up the surface area of a redesigned 726 or future ACV to potentially accept two or even three columns of vehicles. This would significantly force-multiply the 071 and ?075 during amphibious landing.

What the devil happened here? I came in expecting pictures or at least some sort of useful content, instead I see Iron Man screaming at thin air. Did somebody got banned or something?

Guys...steer clear of the personal attacks.

...and if someone attacks you, do not respond in kind. Let myself or one of the other mods know.

Right now, Preux and Iron Man you both are walking too close to that line and it will lead to moderation. Consider this a warning.

As it is, we have seen the existing commissioned and in use LCAC, and we have seen perhaps four new ones.

But we have not seen any with anything close to what would be considered a full load.

until I see that, I am going to presume the PLAN has still not overcome whatever problem they are having....and have been having for years nopw.
