Mikasa (battleship)

Mikasa (battleship). *Mikasa* is a pre-dreadnought battleship of the Imperial Japanese Navy (IJN), famed as the flagship of Admiral Tōgō Heihachirō during the Russo-Japanese War. Laid down in England at the Vickers shipyard in Barrow-in-Furness, she was the last of six *Fuji*-class vessels ordered from British builders. Preserved as a museum ship in Yokosuka, she is the world's only surviving example of a pre-dreadnought battleship.

History

The construction of *Mikasa* was authorized as part of the Imperial Japanese Navy's rapid expansion following the First Sino-Japanese War, under the Ten-Year Naval Expansion Program. Her design was based on the preceding Royal Navy *Majestic*-class, but incorporated several improvements. The order was placed with Vickers due to Japan's still-developing domestic shipbuilding capacity and the desire for the most advanced British warship design. Her name commemorates Mount Mikasa in Nara, a common practice for capital ships in the IJN.

Design and description

*Mikasa* was a typical pre-dreadnought, displacing 15,140 long tons at full load. Her main armament consisted of four 12-inch 40-caliber guns mounted in two twin gun turrets, one forward and one aft. Secondary armament included fourteen 6-inch quick-firing guns and twenty 12-pounder guns for defense against torpedo boats. Protection was provided by a Harvey steel armored belt up to 9 inches thick, with her conning tower protected by 14 inches of armor. She was powered by two triple-expansion steam engines driving twin propellers, giving a top speed of 18 knots.

Service history

*Mikasa*'s most significant service was as the flagship of the Combined Fleet under Admiral Tōgō Heihachirō during the Russo-Japanese War. She led the Japanese line at the crucial Battle of the Yellow Sea in August 1904 and the decisive Battle of Tsushima in May 1905, where the Imperial Russian Navy's Baltic Fleet was annihilated. On the night following Tsushima, *Mikasa* accidentally sank the damaged Japanese destroyer *Akatsuki*. In September 1905, a catastrophic magazine explosion at Sasebo sank the battleship, but she was later salvaged and repaired. She served as a coastal defense ship during World War I and was decommissioned in 1923 under the terms of the Washington Naval Treaty.

Preservation as a museum ship

Saved from scrapping by the intervention of the Japanese government, Allied occupation authorities, and figures like Admiral Chester W. Nimitz, *Mikasa* was restored as a memorial. She was opened to the public in 1926 at her current location in Yokosuka. The ship underwent major restoration work in the 1950s and again in the early 21st century to repair hull deterioration. Maintained by the Mikasa Preservation Society, she is permanently embedded in concrete and features a museum detailing her history and the Russo-Japanese War.

Cultural significance

*Mikasa* is designated a Special Historic Site and serves as a powerful symbol of Japan's emergence as a modern naval power. She is frequently referenced in Japanese popular culture, including appearances in anime, manga, and literature. The ship is a central artifact for understanding the Meiji period's technological modernization and the pivotal Battle of Tsushima, which profoundly influenced global naval strategy. Annual memorial ceremonies are held aboard, honoring the sailors of the Imperial Japanese Navy who served during the Russo-Japanese War.
