Operation Ten-Go

Conceived in the profound desperation of a collapsing empire, Operation Ten-Go was an order that defied strategic logic. The Imperial Japanese Navy dispatched its ultimate deterrent, a vessel kept so secret that its own sailors were unaware of its true dimensions.

Carrying 2,700 men, the Yamato was fueled for a one-way voyage. The directive was absolute: fight through the American blockade, beach the massive hull upon the shores of Okinawa, and act as an unsinkable, static fortress until destruction.

The Sky Descends

The era of fleet-on-fleet engagements had passed. On the morning of April 7, the Yamato faced an enemy it could not fight on equal terms: the sky itself. A total of 386 American carrier-based aircraft located the unescorted giant in the open waters of the East China Sea.

Final Silence

The Yamato capsizes and sinks. Forward magazines detonate in a blast heard 200 km away. A mushroom cloud rises to 6,000 meters. 2,498 men are lost.

As the Yamato slipped beneath the waves, its forward magazines detonated, tearing the ship apart in a blast heard 120 miles away. It was not merely the destruction of a ship, but the violent punctuation mark on an era of naval warfare.

The colossus built to rule the oceans was swallowed by them, a permanent monument resting 1,120 feet below the surface of the East China Sea.
