JS Sazanami
is the fourth vessel of the s of the Japan Maritime Self-Defense Force (JMSDF). 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. 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.
