US Navy submarine propellers are never shown uncovered, even when the vessel is in dry dock. This is not about preventing damage or corrosion. It’s about protecting one of the most sensitive elements of modern submarine warfare. This video explains why submarine propeller geometry is classified, how blade shape affects cavitation and underwater noise, and why a single clear image could allow adversaries to analyze a submarine’s acoustic signature. #Submarines #MilitaryTechnology #NavalEngineerin
