has a hangar, so 64 cells are placed on the foredeck and 32 cells on the afterdeck. These cells contain not only RIM-162, SM-2, and SM-3, but also VL-ASROCs. Additionally, they are equipped with HOS-302, one of the Japanese variant of the Mark 32 Surface Vessel Torpedo Tubes, as anti-submarine weapons. While the Kongō class is equipped with domestic sonar and ASW combat system, the Atago class is equipped with American-made AN/SQQ-89(V)15 with AN/SQS-53C sonar. Only the towing sonar was a domestic OQR-2D-1, which was later replaced with an American-made SQR-20 Multi-Function Towed Array (MFTA). The 127mm bore gun's barrel has been extended from the 54 caliber of the Kongō class to the 62 caliber with strengthened powder charge enabling a firing range. As with other Japanese ships being refit, the American-made Harpoon missiles (such as in the initial configuration of the Kongō class) can be replaced with the Japanese-made Type 90 (SSM-1B) surface-to-surface missiles; those interfaces are compatible.
