A Brief History

On July 12, 1918, the Japanese battleship, Kawachi, suffered a giant explosion in a main powder magazine and sank. The unlucky ship was only 6 years old and her combat career had consisted of bombarding German fortifications at Tsingtao in 1914. Maritime disasters are part of the history of men going to sea, and the military part of maritime adventure is loaded with incidents where the commanders just had to say, “Oops!” In this case, the Japanese Navy had their turn at naval embarrassment and disaster. Please see these below listed links for more great History and Headlines articles about naval “oops moments!”:

Digging Deeper

On the fateful last day of her career, Kawachi was anchored in Tokuyama Bay, waiting for seas to calm in order to conduct torpedo practice. The possibility of intentional arson was considered, but no suspect or motive could be found. Cordite in her magazine may have spontaneously exploded due to deterioration, but that conclusion is not without question. Either way, the Imperial Japanese Navy changed their handling procedures for cordite propellant.

Kawachi was the first of a 2 ship class of battleships, entering service in 1912. She brandished 12 X 12 inch guns in 6 twin (2 gun) turrets, and a secondary battery of 10 X 6 inch guns, 8 X 4.7 inch guns, and 12 X 3 inch guns, as well as 5 X torpedo tubes. The 22,000 ton ship was 526 feet long and 84 feet wide with an armor belt of 12 inches amidships tapering to 5 inches at the bow and stern. Her main turrets were heavily armored with 11 inches of steel, and her bridge protected by 10 inches of armor. Her main deck was only 1.2 inches thick. Despite her heavy armament and armor, the Kawachi was reasonably fast, with a top speed of 21 knots thanks to her 25,000 shp steam turbines.

When Kawachi suffered the fatal explosion, she began to list only 2 minutes later, and a mere 2 minutes after that capsized and then sank. About 600 men died with the ship, and another 400+ were rescued. Any attempt to refloat the ship was dismissed due to cost and delays to other projects had it been attempted.

Going to sea has always been a dangerous proposition, and living aboard a giant powder keg makes it even more so. Mistakes and accidents have taken their toll on ships of every navy, and presumably will continue to do so. Our hats are off to those that dare brave the perils of the sea.
