Agree - not sure why we are messing with the catapults. It will likely add a lot of cost and complications to a design that is already under production. I am guessing that two catapults would put a major strain on the ship's current steam and/or electrical system requiring more systems to be integrated into the platform.USNI: Senate Armed Services Bill Directs Navy to Start a Preliminary Design Effort for a Light Carrier, Pluses Up Shipbuilding Totals Over Trump Budget
If the purpose of a 'light carrier' is just "more hulls with strike capability, cheaper," then the most efficient way of doing that would seem to be building more non-well-deck America-class. Stand up some Navy "light" air wings with a mix of -35Bs and 'Hawks if the Marines don't want to/can't meet the extra requirement. As opposed to designing a new class, which is not going to get any new hulls in the water in less than 15 years, given our ship acquisition processes. Even a modified America-class with cats and AG would add a lot of programmatic risk. All you gain with CATOBAR is E-2 capability, which ain't nothing, but is it worth the squeeze?
I think the simpler answer would be to use the -35Bs / helos as previously mentioned.
