Original Note:

Starlink operates in the 10.7 to 12.7 GHz band. https://radionavlab.ae.utexas.edu/wp-content/uploads/2023/01/starlink_structure.pdf Penetration depth of 2.45GHz in water is <8cm and falls off with increasing frequency. https://cober.com/wp-content/uploads/2018/06/Microwave-Technology-Cober-website-v08-23-17.pdf Therefore, Starlink cannot be used to communicate with an underwater submarine.
