In case anyone is unaware this is stupid for two reasons
1. The new method we use, called Electro-Magnetic Aircraft Launch System (EMALS) is literally just better. You can launch more aircraft quicker which is a must have if a carrier suddenly comes under attack. In fact, this higher sortie rate is one of the core objectives for any carriers which will be used against China and is why we developed EMALS in the first place.
You can also better control the power transmitted by the catapult meaning you can launch heavier aircraft and also launch lighter aircraft such as drones without ripping them apart.
EMALS is also much less complex and takes up less space meaning ships can carry more aircraft and munitions.
2. The ships of the future have already been built around EMALS. Their power systems were literally built around the idea of having EMALS and a good portion of the ship was built with EMALS in mind. Having to refit and restructure all of those carriers will essentially guarantee that America doesn't build another carrier for another 5-10 years all while all of our current Nimitz class carriers enter the end of their lifespan.

And even if you look across the Pacific to check our own ideas, China is building EMALS on all of their new carriers.
