CV-18 Fujian/003 CATOBAR carrier thread

train?

My point exactly it is all about electrical design, which in the commercial market it is still a work in progress. Personally when it comes to crictical infrastructure I will stick to a tried and tested product until the new tech. had been tested to death. But in China's case both system has not achieved operational maturity

Yes.

From China's perspective, both its steam and EM catapults are unproven.

In the 1950th the steam cat was chosen because of its simple design.

And what about a maglev train?

Edit: To be clear I'm not trying to trivialize the technical challenges.

Maglev trains are not subject to the brutal operating conditions military equipment is call to operate in.

Capacitors are solid state electronics, which are less complicated and prone to failure.

Plus my understanding is that EMALs uses spinning flywheels for energy storage rather than capacitors.

Don't know about the storage medium use on EMALS but large capacitors use for energy storage that are call upon to release massive amount of energy, even though solid device they maybe can fail in a dramatic way. I had one that blew up on commissioning and did not hurt anyone because it is install in a blast resistance cabinet.

Don't know about the storage medium use on EMALS ...

The CVN-78 from the US-Navy uses three systems with four flywheels each, distributing the energy to four catapults. The landing gear uses electrical energy, too.

Yes, which is why they went with spinning flywheels for EMALs energy storage on the Ford-class carriers.

Going for EMALS means 002 will not be commissioned in Xi's presidency, takes some courage to make the call.

Unless Xi's presidency is stretched.
