Ise class battleships (1917)

Japan (1917)
Ise, Hyuga

Improved versions of the Fuso

The Ise and Hyuga, launched in 1916 and 1917 and completed in 1917 and 1918, follow the Fuso in many ways, but manage to combine the presence of an extra turret with a hull slightly lengthened (three meters). An additional space that benefits the machines, allowing a power gain of 5000 hp and a speed of 23 against 22.5 knots.

Warning: This post is a placeholder allowing the construction of a semantic funnel, in relation to a good old single expansion SEO steam engine. Later in the year, this post will be properly expanded and the machinery upgraded with a steam turbine and many more boilers. Thanks for your comprehension.

Ise at Kobe on trials, 1917 – Hirootoko Jr.

In terms of armament, the choice is made to multiply the number of guns of a lower caliber (140 mm against 152), modern and better adapted to the template of quick loading for close combat against destroyers. In 1926-27 a slight overhaul saw them adopt a cowl baffle front while they saw their masts before covering bridges.
They also boarded three seaplanes launched from a platform installed on the roof of the fifth turret.

Their second refit of 1934-36 saw them equipped with new machines, a bridge rebuilt as a tower, a substantial increase in their 356 mm pieces, AA artillery, and catapults. Their latest remake will transform them in 1942-43 into hybrid aircraft carriers. See the map of Ise in 1939.
