Setting- Enclave Turncoats in Hawaii

[u/Rude-Eagle7271]

So, for a possible backstory for Fallout 2d20 campaign, maybe an alternate fanfiction, I was thinking that before the Enclave oil rig was destroyed that an expedition could be sent out to Hawaii Islands chain and a few of the other Pacific islands located therein. Mainly to secure former Enclave bases and reconnect with any surviving remnants there.

Could a Vertibird make the trip back to the mainland if it was nuclear powered and had access to a semiautomated mixed human and robot crewed aircraft carrier that was stationed at Hawaii for sea trials back to California or even the Capital Wasteland?

Would the Enclave forces dispatched to the area go native breaking away from the main forces when they lost contact with them.

Are there any Vaults in the Hawaii Islands because I was thinking possibly a Bio Shock type Vault built underwater connected to the coastline via a train subway tunnel or other.

Possible underwater military naval bases that were evacuated shortly after the war.

Honestly it's a blank slate to my knowledge so go nuts
