Warship Vasa Capsizes: Sweden's Pride Sinks on Launch

The most powerful warship in the world sailed less than a mile before capsizing and sinking to the bottom of Stockholm harbor, taking roughly 30 crew members with it. The Vasa, pride of the Swedish navy and personal obsession of King Gustavus Adolphus, went down on its maiden voyage on August 10, 1628, barely twenty minutes after leaving the dock. A gust of wind heeled the ship to port, water poured through the open lower gun ports, and 64 bronze cannons dragged the vessel to the harbor floor in 100 feet of water. The Vasa was an engineering marvel ruined by political interference. King Gustavus Adolphus, locked in wars across the Baltic, demanded a warship of unprecedented size and firepower. He personally approved the dimensions and ordered changes during construction that made the ship dangerously top-heavy: an extra gun deck was added, increasing the number of heavy bronze cannons without a corresponding widening of the hull. The ship's ballast — 120 tons of stone in the hold — was insufficient to counterbalance the weight concentrated high above the waterline. The problems were known before launch. A stability test in which 30 sailors ran back and forth across the deck was halted after just three passes because the ship rocked so violently it nearly capsized at the dock. But no one was willing to tell the king his flagship was fatally flawed. The admiral in charge, Vice Admiral Klas Fleming, ordered the ship to sail despite the test results and the captain's reported reservations. The Vasa sat on the harbor floor for 333 years before marine archaeologist Anders Franzén located the wreck in 1956. The cold, brackish waters of the Baltic had preserved the ship to an extraordinary degree, and it was raised largely intact in 1961. Today the Vasa Museum in Stockholm is Sweden's most visited museum, drawing more than a million visitors annually. The ship that was too unstable to sail became a perfectly preserved time capsule of 17th-century naval engineering and a cautionary tale about the consequences of overriding expert judgment.
