Armour

The two Yodo-class dispatch ship (淀型通報艦, Yodo-gata tsūhōkan) were a class of small, high-speed,

protected cruisers. The Yodo class was followed by the larger, more conventional Chikuma class.[1]

Background

The Yodo-class cruisers were designed and built domestically in Japan, having been ordered as part of the 1904 Emergency Fleet Replenishment Program to recover from losses to the Japanese navy from the

wireless communication used during the Russo-Japanese War of 1904-1905. Both ships were reclassified as first class gunboats on 12 October 1912.[1]

Design

The design of the two Yodo-class cruisers differed noticeably. Not only was Mogami larger and heavier than Yodo, it also had a straight raked bow with three smokestacks, compared to Yodo which had a clipper bow and two smokestacks. Another significant difference between the two ships was their propulsion systems, while Yodo had a conventional two shaft, four cylinder

reciprocating (VTE) engines with four Miyabara boilers, Mogami has the distinction of being the first Parsons-type turbine-powered vessel in the Imperial Japanese Navy.[1]

The Yodo class was armed with two

QF 12 pounder 12 cwt naval guns. The Yodo class was armed with three 457 mm (18.0 in) torpedo tubes. Armour protection of the Yodo class consisted of 64 mm (2.5 in) of Krupp armour on the deck and 51 mm (2.0 in) on the conning tower. The design did not incorporate any side armour.[1]

Ships in class

Two ships were budgeted for and completed under the 1904 Emergency Fleet Replenishment Program, one each from the

Nagasaki. Both ships served in World War I. The Yodo additionally in the Second Sino-Japanese War and the first months of World War II, and were scrapped before the outbreak of the Pacific War.[1]

Yodo ()

Yodo was completed on 8 April 1908, at the

Republic of China, with her patrol range extended during after the beginning of the Second Sino-Japanese War
in 1937.

Yodo was demilitarized on 1 April 1940 and renamed Hulk #13. It remained moored to a pier at Iwakuni throughout World War II, and was finally broken up for scrap in 1945.[1]

Mogami (最上)

Mogami was completed on 16 September 1908, at the

Bolshevik Red Army during the Russian Civil War
.

Mogami was scrapped on 1 April 1928. Although Mogami was considered the more modern and advanced in design, with her higher speed and turbine engine, she was retired much earlier than her sister ship, Yodo, largely due to performance and maintenance issues with her engines.
