In 2023 Australia acquired a former oil rig support ship, to use as a 
drone tender, renamed ADV Guidance.

Australia already had two similar ships, ADV Reliant and ADV Ocean 
Protector. The latter had "moon pools", which are hatches in bottom of 
the ship. These allow a drone to be launched and recovered out of sight. 
Very James Bond. ;-)

The details of the Ghost Shark submarines are classified, which leaves 
us free to speculate. ;-)

My guess is they would be preprogrammed to follow a set course, but come 
up to periscope depth, to report anything of interest, via satellite (by 
radio or laser). Crewed submarines use low frequency radio to receive 
messages, but the antenna is too big for a drone.
