history
Planning and construction
In 1984 the United States Navy began looking for overseas buyers for the Aegis combat system . Four years later, in 1988, the contract with the Japanese Navy came about. As a carrier ship for the system, the JMSDF chose a modified Arleigh Burke-class destroyer adapted to Japanese needs . The first ship, the Kongō , was laid down on May 8, 1990 and commissioned with the Japanese Navy on March 25, 1993. The last ship in the class, Chōkai , entered service in 1998.
Two more ships were ordered in 2000 and entered service as the improved Atago class in 2007.

technology
Hull and drive
The Kongō-class destroyers are technically based on the Flight I Arleigh Burke-class destroyers. The hull is 161 m long and 21 m wide, the draft is 6.2 m, the displacement is 9,485 ts . The hull and superstructure are stealth -based and tilted from the vertical to reduce radar reflection. There is a helicopter landing pad on the stern, there is no hangar for permanent storage of a helicopter on board.
It is powered by four Ishikawajima Harima / General Electric - gas turbines LM2500-30 who cast their total output of 100,000 shaft horsepower to two waves with a single screw. The top speed is 30 knots (56 km / h), the maximum range 4,500 nautical miles (8,334 km) at 20 knots (37 km / h).
Armament and Electronics
The armament of the Kongos is housed like that of the American models in two Mk 41 VLS with a total of 90 cells. According to the Japanese doctrine, the ships only have defensive weapons, offensive weapons such as Tomahawk cruise missiles are not on board. The Mark-45 lightweight gun of Burkes is by a compact gun same caliber of Oto Melara replaced. There are two Phalanx CIWS on board the ships to defend against anti-ship missiles .
The main radar system on board is the SPY-1 radar of the AEGIS system , the four surface antennas of which are located on the superstructure. The fire control of the RIM-67 anti-aircraft missiles is carried out by three AEGIS FCS Mk99 radars, the antennas of which are located on the superstructure. As Bugsonar using vessels a OQS-102 sonar. The computer systems of the AEGIS system were expanded to include a submarine hunt component in order to meet the requirements of the Japanese Navy.
The NOLQ-2 jamming system is on board for electronic warfare , and the ships also have a towed SLQ-25 Nixie torpedo deception system.
On November 19, 2008, JDS Chokai (DDG 176) launched a Standard Missile 3 as a test as part of the US missile defense program. An attempt by the Missile Defense Agency to hit a US medium-range missile launched from Kauai, Hawaii failed.
