Original Note:
Context: Although the support vessel on the surface uses Starlink, all communication with the sub is via text message transmitted using low frequency radio and has nothing to do with Starlink. Starlink operates in high frequency (SHF/EHF) bands and can't be used underwater. https://en.wikipedia.org/wiki/Communication_with_submarines https://www.americantv.com/what-frequency-does-starlink-use.php
