First Japanese Suicide Submarine Attack in 1944

Prelude to the Attack on Ulithi Atoll

The Japanese Strategy

As World War II progressed, Japan faced severe challenges in the Pacific Theater. Despite their early successes, the tide was turning against them after significant losses at battles such as Midway and Guadalcanal. The Japanese military began to explore more unconventional tactics, leading to the inception of the suicide submarine attacks, known as the 'Kairyu' (meaning "ocean current") to inflict devastating damage on Allied naval forces.

Ulithi Atoll: A Strategic Location

Located in the Caroline Islands, Ulithi Atoll served as an essential base for the U.S. Navy during the war. Its strategic positioning provided a perfect spot for staging operations in the Philippines and further into Japanese-held territories. On November 25, 1944, it became the target of Japan's desperate measures as they attempted to turn the tide of the war.

Executing the Kairyu Attack

In the early morning hours, **Japanese submarines** launched a surprise attack on U.S. naval vessels anchored at Ulithi. This operation marked the first use of **suicide submarines** in American waters, demonstrating Japan's commitment to employing all available resources to counteract Allied naval dominance.

Consequences of the Attack

The attack resulted in a mix of luck and flaw, with only limited successes. While the Japanese managed to sink a few vessels, the overall impact was minimal compared to their losses. The U.S. Navy's well-prepared defenses minimized damage, and they went on to learn and adapt to this new tactic in the following engagements.
