The 35-Knot Monster That Made Enemies Instantly Retreat—Or Be Destroyed


In the brutal naval battles of World War II, there was no room for hesitation. Hesitate, and you were dead. The Pacific was a graveyard for the slow and the weak, where Japanese warships and kamikazes prowled the waters, ready to strike at any sign of vulnerability. But then came a ship so fast, so heavily armed, that it turned the tide of battle just by appearing on the horizon. It was a war machine built for speed, destruction, and total domination.

She was the USS Alaska—a battlecruiser in all but name, a ship that combined the speed of a cruiser with the firepower of a battleship. And when she arrived on the battlefield, the enemy had only two choices: run, or be obliterated.

With a blistering top speed of 33 to 35 knots, the Alaska could outrun nearly anything her size. Traditional battleships lumbered across the sea at barely 27 knots, unable to keep up with fast-moving targets. But Alaska? She was different. She raced across the Pacific like a predator, hunting enemy cruisers and anything else unlucky enough to cross her path.

And then there were her guns. Nine 12-inch Mark 8 naval rifles—smaller than the 16-inch monsters on Iowa-class battleships, but devastating against anything lighter. Japanese cruisers that once terrorized Allied convoys suddenly found themselves hopelessly outgunned. They couldn’t outrun her. They couldn’t outshoot her. They could only die or flee.

When the USS Alaska and her sister ship, USS Guam, entered service in 1944, their first missions made one thing clear: these ships were apex predators. They shredded enemy aircraft, bombarded coastal defenses, and provided cover for carrier strike groups with unmatched speed and firepower. In the final months of the war, Alaska escorted fast carriers during raids on the Japanese homeland, swatting down enemy planes and ensuring the carriers remained untouched.

But despite her dominance, the Alaska class was a ship born too late. The war was already shifting toward air power, and the need for traditional surface combatants was fading. Though designed to counter German pocket battleships and Japanese heavy cruisers, neither threat materialized in the way planners expected. The Alaska never faced an enemy battlecruiser or pocket battleship in combat—because by the time she arrived, they were already running or sinking.

Her career was short, but her legend endured. The USS Alaska was proof that speed and firepower could rule the seas, even in an era dominated by carriers. For the enemies who saw her coming, she was a nightmare—one that gave them just two choices: retreat, or be destroyed.
