Is this because of a steel shortage?

"Supply chain issues". That's what I read, without many specifics.

It seems to be that large ships are floating targets for drone strikes.

I've read that they are trying to factor in that new dynamic of warfare. Keep in mind that a supercarrier never goes anywhere by itself. It has numerous escorts, all of which are tasked with protecting it. I suspect they are figuring out how to get the screening vessels better equipped to deal with drones. The utility of the carrier in projecting power is too great to abandon the platform.

They've been vulnerable to diesel subs since forever. Seems every time we have an exercise, a smaller nation (e.g. Sweden) has a diesel boat that manages to "sink" one of our carriers.
