@officialkaizenlab: Radar goes dark the second it hits water. Submarines run on sound instead, and that single physics constraint shapes almost everything about undersea warfare. Radio waves get absorbed within feet of entering seawater, while sound propagates for miles, which is why sonar became the only viable way to find something hiding below the surface. It’s also why the quietest submarine wins: active sonar gives away your position the moment you ping, so most hunting happens passively, just listening. #sonar #submarine #military #creatorsearchinsights #worththesearch
