About the Japanese destroyer

JS Ōnami (DD-111) is the second vessel of the Takanami-class destroyers of the Japan Maritime Self-Defense Force (JMSDF). She was commissioned into service on 13 March 2003 and was initially assigned to the JMSDF Escort Flotilla 1 based at Yokosuka.

The hull design is generally based on the one of the Murasame-class. However, as a part of the 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.

The ship has a length of 151 m (495 ft 5 in), a beam of 17.4 m (57 ft 1 in), and a draft of 5.3 m (17 ft 5 in). She can reach a top speed of 30 knots (56 km/h; 35 mph).

The destroyer is armed with Otobreda 127 mm/54 gun, two missile canisters up to 8 Type 90 (SSM-1B), two 20 mm Phalanx CIWS, two Type 68 triple torpedo tubes VLS Mk 41 (32 cells) with Evolved Sea Sparrow SAM and RUM-139 VL ASROC.
