History of Truk Mitsubishi

Truk Mitsubishi was originally a major Japanese naval base during World War II.

The lagoon provided sheltered waters and a natural harbor, making it an ideal spot for the Japanese to base their operations in the Pacific.

In February 1944, the United States launched Operation Hailstone, a massive air and naval attack on Truk Mitsubishi.

The operation was highly successful, resulting in the sinking of over 40 Japanese ships and the destruction of numerous aircraft.
