Hidden for a reason: Why submarine propellers are key to national security

Submarine propeller designs are highly classified due to their critical role in acoustic stealth and survivability. Cavitation noise from propellers is a major vulnerability, and advanced designs aim to minimize it. Insights into these designs, even from recovered parts, have significantly impacted anti-submarine warfare tactics and strategic deterrence.
