There is not a navy dive team stationed in key west. We bring in the teams for assault training, and MDSU divers from little creek for more pedestrian dives. I do a lot of the commercial diving for the Navy here in Key West. For a Navy Diver to do a dive like that would be a huge deal.
Key West does have the Army Dive School. The students are in no way qualified to make that dive. The instructors are short handed and that isn’t really their gig.
Blesers team is/was the only team in the world that is/was formally formed to provide that service. A team of volunteers.
Cave rescuers like we saw in Thailand and north Florida are throw together teams of expert cave divers, and I take nothing from them, but the Key Largo WET is a special
Team with a special mission. For the navy to come down for that would have required mobilization of millions in assets and weeks of planning.
The Coast Guard does not even perform their own ships husbandry in Key West or Miami
