Regarding the number of catapult on 003 being 3 instead of 4 as USN, here is a research paper from 2016 by China Ship Development and Design Center. Title "基于闭排队网络的弹射器数量配置方法"/"Method of the catapult quantity deployed by using closed queuing network"

Here is the conclusion,
Based on data from Nimitz 1917 high tempo exercise, the research concludes that 2 catapults are enough.

From table 2 and the diagrams, it can be seen that only when T_launch=6min, 2 catapults will be close to 100% used which is too much. In all other cases, there is enough margins. This means 2 is the minimum and runs some risk of overloading the catapult. 3 is as good as 4. 4's redundancy advantage then 3 is visible but insignificant.

MQ-25 Stingray is essentially a cargo drone, so this is probably coming.

I do not think drone tech is sophisticated enough to do Anti Submarine warfare missions yet, at least not in the near term.
Since ROCN and Australia are both threatening to put more subs in the water in the sooner rather than later, along with Japan's already decent fleet, PLAN cannot wait for the technology to mature.

PLAN has been busy designing new method to find Submarine. They have program using laser and the conventional way of high Frequency sonar and sossus planted in south china sea(underwater great wall) There is dedicated thread in this forum check it out China coastal ASW or something like that. They even think of using satellite to find submarine. But first they have to make sensor small enough to carry into the satellite. Last I heard they have built small sensor mounted on Cessna plane

What's the bottleneck that causes this? So when you have 35 planes, 3 cats or 4 cats still yield the same sortie rate, the bottleneck is in plane handling on deck?

My data might be not correct, but as far as I found, the cargo weight of C-2 Is less than 5 tons. CH-53K is 14 tons+.

Yes, I should make a correction that C-2's irreplaceability by CH-53 is determined by capacity, speed and range altogether, not one single parameter. C-2 has more than twice the range and cruise speed of CH-53. These capabilities greatly increase the flexibility of aircraft carrier deployment.

Also CH-53K was just certified its IOC in April 2022 (although previous subtypes of H-53 have more payload weight than C-2 too).
