Japanese destroyer Matsu (1915)

Matsu (松) was one of 10 Kaba-class destroyers built for the Imperial Japanese Navy during World War I.

Design and description
The Kaba-class destroyers were improved versions of the preceding Sakura-class destroyer. They displaced 665 LT at normal load and 850 LT at deep load. The ships had a length between perpendiculars of 260 ft and an overall length of 274 ft, a beam of 24 ft and a draught of 7 ft. The Kabas were powered by three vertical triple-expansion steam engines, each driving one shaft using steam produced by four Kampon water-tube boilers. Two boilers burned a mixture of coal and fuel oil while the other pair only used oil. The engines produced a total of 9500 ihp that gave the ships a maximum speed of 30 kn. They carried a maximum of 100 LT of coal and 137 LT of oil which gave them a range of 1600 nmi at a speed of 15 kn. Their crew consisted of 92 officers and ratings.

The main armament of the Kaba-class ships consisted of a single quick-firing (QF) 12 cm gun located on the bow. They were also armed with four QF 3 in guns on single mounts. Two guns were positioned abreast the middle funnel, one gun was on the aft superstructure and the fourth gun was on the stern. The destroyers' torpedo armament consisted of two twin rotating mounts for 450 mm torpedoes located between the superstructure and the stern gun.

Construction and career
Matsu was laid down at Mitsubishi's shipyard in Nagasaki on 3 November 1914, launched on 5 March 1915 and completed on 6 April. During World War I the ship patrolled the area around Singapore and later served as a convoy escort in the Mediterranean Sea. Matsu was damaged during the 1923 Great Kantō earthquake, but was repaired. She was stricken from the navy list in November 1931, was decommissioned on 1 April 1932 and subsequently broken up.
