Never heard of any modern PLA ship disaster for the last 10 years...!
If your Navy Friend is from the US Navy, let me remind him about the USS Fitzgerald crashing into a gigantic container Ship, USS Bonhomme catching on Fire due to negligence and a Seawolf Submarine crashing into who-knows-what. All these disaters occured within the last 5 years.....in Peacetime....! From this small sample, I would deduce that the Chinese Navy is far more Professional and organised than the 'Rambo-style' US Navy.
Is it too small a sample to make any judgement....? Maybe....but that is exactly what many so-called US 'experts' or 'anal-ysts' do when talking about the Chinese Military. They pick on the tiniest flaws and make a mountain of it. Using the same yardstick for both the USN and the PLAN, we can correctly conclude that the Chinese Navy is more capable with the platforms that they have, judging on recent records.
