The Takanami-class destroyer (たかなみ型護衛艦, Takanami-gata-goei-kan) is a class of destroyer serving with the Japan Maritime Self-Defense Force (JMSDF). This warship is the slightly modified class of second-generation, general-purpose destroyers of the JMSDF.^[1]

Background[]

Since FY1991, the JMSDF started construction of the second-generation, general-purpose destroyers (汎用護衛艦, Hanyou-goei-kan), Murasame-class. These destroyers are generally satisfactory for the fleet, but there is some discontent.^[1]

From FY1998 onwards, a slightly modified version that corrected these dissatisfaction points was to be built: Takanami-class.^[1]

Design[]

The hull design is generally based on the one of the Murasame-class. However, as a part of weapons was changed, the internal structure has also been changed. And it was said that the large lattice mast was degrading its stealthiness in the Murasame-class, so in this class, it was considered to change to two small masts, but it was not implemented.^[2]

Although its displacement become slightly increased, there is no change in its main engines, as it is not a big difference that has little effect on the performance of the ship.^[2]

Equipment[]

The combat system was slightly improved. The combat direction system is similar to Murasame-class in the first three ships, but in the fourth ship, workstations are changed to AN/UYQ-70, and in the fifth ship, it corresponded to the communication in Link 16.^[3] Radars are the same as those of Murasame-class, sonars are also small revision type.^[4]

In terms of weaponry, instead of the 3-inch gun that has been adopted by conventional DD type destroyers, a larger Oto Melara 127 mm gun is introduced. Although vertical launching systems were divided into two places in the Murasame-class, 16-cell Mk 41 for VL-ASROC on the bow deck and 16-cell Mk 48 for Sea Sparrow (later replaced with Evolved Sea Sparrow) on the middle deck, they are compiled in one place, 32-cell Mk 41 on the bow deck in this class.^[4]
