【Military Vision Mini Classroom】Heavy Weapon of the Deep Sea! The People's Navy Submarine Force Forges an 'Underwater Great Wall'

On the 72nd founding anniversary of the People's Liberation Army Navy submarine force, PLA military media published a retrospective framing the force's development as a progression 'from nothing to something, from weak to strong,' invoking the 'Underwater Great Wall' formulation to characterize its strategic deterrence role. This is anniversary commemorative content; its value is as a record of how the institution publicly frames submarine force identity and historical narrative for a general audience, not as evidence of changed posture or capability.
