PROGRAMME Proposed in the FY87 program; first one accepted in FY88 estimates, second in FY90, third in FY91, fourth in FY93. Designated as destroyers but these ships are of cruiser size. The combination of cost and US Congressional reluctance to release Aegis technology slowed the program down but the plan is to complete all four by mid-1998.
STRUCTURE This is an enlarged and improved version of the USN Arleigh Burke with a lightweight version of the Aegis system. There are two missile magazines. OQS 102 plus OQR 2 towed array is the equivalent of SQQ-89. Prairie-Masker acoustic suppression system.
OPERATIONAL As well as air defense of the Fleet, these ships contribute to the air defenses of mainland Japan. Planned to become the Flagship for each of the four Escort Flotillas.
