The Sankisan Maru is one of the most heavily damaged ships sunk in Truk Lagoon. An aerial bomb hit an ammunition cache in the stern of the ship and blew it completely apart. The bow and midship are relatively intact. The Sankisan was a supply ship carrying ammunition and medical supplies to the Japanese Fourth Fleet base in Truk.

The Hoki Maru was transporting aviation fuel to the supply base at Truk. An aerial bomb hit the ship and it exploded in a fireball. The fire raged fiercely below deck, killing most of the Japanese crew.

The Nippo Maru is one of the deeper wrecks in Truk Lagoon. She was most likely sunk by a 500 lb. aerial bomb on the first day of the attack. The helm and compass on the bridge are signature features, as well as a large tank secured to the midship deck.
