Seems like it was an SSBN which came in and out very quickly. Quite unusual as the article makes clear.
From the War Zone article:
' it does not appear to have the modified hull associated with the four SSGNs, indicating that this is one of the remaining 14 Ohios configured to carry nuclear-armed ballistic missiles, also referred to as SSBNs.'
'When asked, @WarshipCam, who spotted the submarine entering San Diego Bay, was kind enough to provide the following additional information:
Basically, the Ohio class submarine came into San Diego today and did a quick turn and headed back out. Ohio class subs don't come into there all that often - with the last one I've seen being in May of 2020. At that time the incoming Ohio was involved in a missile test.
Without knowing which Ohio class submarine this for sure, it is difficult to try to determine what its reason or reasons for visiting San Diego might have been. We have reached out to U.S. 3rd Fleet, which is headquartered in San Diego, seeking more information about this brief stopover.'
