Nuke subs are (if I recall correctly) two pressure vessels of thick welded steel. There are well developed processes for working it and it is very forgiving. It’s a classic material that works very well.
CFRP is the last material I would use without a redundant structure for a sub’s main vessel. It’s challenging material to get right and flaws can be difficult to spot, even with ultrasound/xray. For fins, ducts and interior furniture, etc that’s fine.
U.S. subs are only one pressure vessel (single hull). The steel is HY (high yield) series. Russian subs typically have double hulls, where the inner hull is the pressure hull and the outer hull is the hydrodynamic hull.
Don't look into titanium Russian subs. Can dive deep, but causes embrittlement and interstitial defects in the material shrinking its depth band for the remainder of ship life.
Anyhow, Hadish was symbolizing Biden. Check his insta, 404 (not found) posts, started off high, ended way low, then it turns out it was a catastrophic implosion known to the administration. Comms point to rapid loss of Biden.
yeah maybe in a sphere, but the way the layers are created matters as to the strength to withstand a particular force in a particular direction. From what I saw of the wrapping it did not seem very sophisticated beyond fixed hotdog wrapping.
I don’t know why, of all materials, to use cfrp.
More pressure? no problems, more layers! That's totally how mechanical engineering works.

US subs have a hydrodynamic hull that wraps the ballast tanks. It's not really a double hull in the sense of a CVN though.
Lightweight, somewhat durable. It makes sense, but should be backed by other materials too.
Man at that depth I want titanium around me, and lots of it.
At that depth I'd want to be tethered to something so if something went wrong I could be reeled back in
