That ski-jump flight deck is a cheap, low-tech approach to launching aircraft, but it has a serious problem: You can't launch an aircraft with either a full fuel or weapons load . . . Only a catapult can accomplish that. It sorta leaves you with some limited options.
Yup!
And it's conventionally powered, and it holds half the air craft with half the payload capacity (it's likely closer to 1/4), and inexperienced crew.
At BEST, it's 25% of an American carrier.
Then there's experience with long range deployments, extended tours, supply lines, underway repairs and refitting.
That thing is merely a engineering and operations training tool and would be a reef within 30 minutes of a real engagement.
