Jeff, do you know how much it takes to introduce anything new in the PLAN? New ideas, designs, moving things forward to the edge? Those things in the video were done more than 15 years ago. If there's someone who could push changes through in the command is a mystery. They're doing something but nothing fresh. If there's time to push new ideas is right now - when they're growing. Not when stagnation and replacement will come from this wave of 'new toys' some 30 years forward.
The Chinese Navy and Chinese military's path of R&D is immensely opaque, even more opaque than their procurement decisions.
If you're suggesting that there is no active R&D into future capabilities and doctrines, I think that's being a little bit presumptive, isn't it? If anything, considering the Chinese Navy and military's overall path of rapid development in the last decade, it should be reasonable to assume that they recognize the continuing importance of domestic R&D, especially as they are pushing up to the forefront of some existing established concepts and capabilities.
My only problem with PLAN is - when you have all those money why are you making loads of rudimentary 056 class ships which will be able to push Brunei Navy back home instead of pushing new ideas which will give you an edge for the future? Not that have anything about them but all they could in case of war would be going from one naval base on the coast to another waiting for what? Because bigger boys with more powerful radars won't have to go against them with some serious money wasted on keeping them alive. Is the problem within PLAN's nowadays officials? They don't have any visionaries in the top echelons? The tech difference is somewhat 20 years backwards like many users here wouldn't like to see? Or they're waiting for the end of the world? Because Wunderwaffe theorem is outdated - Japanese and Germans already showed that.
I'm not really sure what you're asking -- are you suggesting that the 056 class corvettes are unnecessary for the Chinese Navy's requirements, or that they are not "innovative," or both?
Because I think few people would say that the 056 class corvettes are inconsistent with the Navy's requirements, especially when considering the other procurements of the Navy.
You can argue the 056 class isn't a groundbreaking design and that it doesn't offer any groundbreaking technologies, but is that the metric to which the 056 class (or any military asset) should be measured at, instead of measuring them by how well they fulfill their intended mission? (do you even know what the role of the 056 class corvette is meant to be?)
And what has wunderwaffes or Brunei Navy got to do with anything? I think your "only problem with PLAN" is not very well described.
