Submarine warfare evolves from hand-cranked curiosities to stealthy nuclear deterrents shaping global sea power.
Submarines pioneered stealth not by quieter engines but by trolling crews to ignore onboard noise, creating the first acoustic stealth arms race.
Nuclear submarines trade speed for silence: they travel slower submerged to avoid cavitation revealing their presence.
German U-boats influenced modern sonar by accidentally using 'shadow zone' tactics that revealed how propeller wake betrays subs.
The most effective anti-submarine weapon in WWII was actually a depth-sounding batched into air-dropped signals, not conventional depth charges.
