Commodore? I didn’t think the USN used that title/rank anymore.

There is no rank of commodore in the US Navy. It was changed (over 25 years ago) to Rear Admiral, Lower.
Per Wiki “Today, it is no longer a rank, but it continues to be used as an honorary title within the U.S. Navy and the U.S. Coast Guard for those senior captains (pay grade O-6) in command of operational organizations composed of multiple independent subordinate naval units (e.g., multiple independent ships or aviation squadrons).”
I was enlisted. Never heard a Captain being referred to as Commodore.
Perhaps they were uncomfortable calling him ‘Lower Half’?
A senior Captain, usually on track for Admiral, with more than one ship under his overall command. (My memory)
Wiki: An American commodore, like an English commodore or a French chef d'escadre, is but a senior captain, temporarily commanding a small number of ships, detached for any special purpose. He has no permanent rank, recognized by government, above his captaincy; though once employed as a commodore, usage and courtesy unite in continuing the title.
