He is just frustrated at the lack of quality or availability of auxiliary systems around the ships like the LCAC or helicopters. Which are required to make them effective. Compared to these highly sophisticated surface vessels those systems are way behind.
I also share in his opinion. Especially in older ship types without the variable depth towed sonar the lack of available helicopters means ASW capabilities are severely flawed. The LPDs also become less useful in operations due to the lack of available landing craft including LCACs or modern heavy transport helicopters.
I think the reason for these problems is actually one and the same. The lackluster capacity of the Chinese military industry to manufacture efficient gas turbines in quality and quantity. The WZ-10 attack helicopter in that regard was a significant milestone. But even that was fraught with the engines performing below the original spec in terms of power and durability. Both the LCACs and the new helicopters in design need gas turbines to operate.
I suspect that is the reason we do not see either the LCACs or helicopters more available and in use in training operations. With the helicopters the PLAN might also not want to order more because they expect better equipment to become available sooner rather than later. With the LCACs they might be manufacturing boats with the expectation the engines will be sorted out later.
Unlike a surface vessel, an LCAC needs a marine engine with a lot more power to weight to be able to operate. Similar to an aircraft's but in martime conditions with sea salt, water spray, and things like that. This is a demanding challenge.
