Did they get to name it before being fired? Also has someone now charted it?
Technically speaking, we now know that there is a seamount somewhere in an area couple of miles wide. It’s exact position, depth, and area coverage would still be unknown.
Someone (preferably either a 5 Eyes nation or Japan/South Korea/Singapore) needs to send hydrographic survey ships to do a formal survey of the area. Easier said than done as there isn’t a huge survey capacity at start with and they are some of the busiest ships in any Navy and quality commercial survey ships have years of back orders just supporting oil exploration.
