>>64007674 (OP)not ideal, mk48 is self guided with active sonar but whales don't give good active sonar signatures compared to subs
Subs have a hollow space full of air inside them so the ping bounces really well off it, the majority of the whale is watery flesh, you'll get a return but a lot of the ping just passes through
>>64008764it would have to be extremely close to hurt it, at most sonar confuses whales, even then theres way more noise pollution along shipping channels just from all the propellers that it is more likely to fuck with whales than sonar
>>64009082sonar could boil water, but then it's at a level that it would likely damage itself, it doesn't happen in regular use
