JS Ōnami

is the second vessel of the s of the Japan Maritime Self-Defense Force (JMSDF).

Design

The hull design is generally based on that 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.
