The Alaska-class cruisers were massive, expensive ships that struggled to find a clear purpose.

In short: Designed to hunt down enemy cruisers, the Alaska-class ships were a unique hybrid in the U.S. Navy. Too large to be standard cruisers and too lightly armored to be true battleships, these vessels spent their short careers as carrier escorts before being decommissioned just years after the war ended.

The Alaska-class emerged from a desire to counter German pocket battleships and rumored Japanese super cruisers. During the late 1930s, the U.S. Navy sought a vessel that could outmatch existing heavy cruisers. The resulting design, officially designated as a large cruiser (CB), was a scaled-up version of the Baltimore-class. These ships featured nine 12-inch guns, which were remarkably powerful for their size, yet they lacked the comprehensive underwater protection found on contemporary battleships. This vulnerability made them susceptible to torpedoes and near-miss shell impacts, despite their impressive 33-knot speed.

The construction process was notoriously difficult, involving at least nine different design layouts. While the U.S. Navy insisted on the large cruiser classification, many observers and historians have frequently labeled them as battlecruisers. This debate was fueled by their appearance, which mirrored that of U.S. battleships, and their intermediate size between heavy cruisers and capital ships. To emphasize this unique role, the Navy named the ships after U.S. territories rather than states or cities. However, their high cost and limited utility meant that of the six planned ships, only Alaska and Guam were completed and commissioned.

By the time Alaska and Guam entered service in 1944, the threat they were built to counter had largely vanished. They spent their limited time in the Pacific screening aircraft carriers and conducting shore bombardments. After the war, they participated in occupation duties in Korea before being decommissioned in 1947. Subsequent efforts to convert them into guided-missile cruisers or command ships were abandoned due to prohibitive costs. By 1960, the remaining ships were stricken from the register and sold for scrap, marking the end of a brief and controversial chapter in naval history.
