Well this is troubling. I'm skimming through that link and it seems that the first link you posted might be* a rehash of this one. That would make the claims about IEPS and EMALS in the first article you posted 3 years old.
Not troubling per se, but why all of sudden is this making the rounds again? Ostensibly it's because the Chinese EMALS breakthrough has made it into Western news in the past week; but this likely baloney, since I've yet to see any recent Western coverage of China's EMALS program.
Then why have the Chinese rehashed this old article now? Are they perhaps implying that their EMALS is finally mature?
But remember Mr. Ma Weiming was also responsible for breakthroughs in IEP. It's possible the Chinese may in fact be suggesting that they now have mature electric propulsion technology for large surface combatants.
Or, maybe China has got both EMALS and IEP nailed.
What I know for sure is that the Chinese have voluntarily rehashed an old article from three years ago, ostensibly due to very recent Western press coverage, which doesn't actually exist. The Chinese maybe telling us something without making an announcement, which can be perceived as too 'aggressive'.
"The West thinks we've done this" is much softer than "look at what we've done".
