LOST BY CAPSIZING IN THE INLAND SEA.
For protection there is a steel deck 1½ ins. thick on the slopes. With this is associated a cellulose belt and coal protection. The total protection, so far as penetration is concerned, is not, however, more than equivalent to what a 6-in. belt of old iron armour would afford, and it would keep out nothing above a 4.7-in. shot, and that only at long ranges. Over the engine hatches is a patch of thick steel armour.
The heavy gun barbette is a strip of 12-in. Creusot steel, with a 4-in. steel shield over the breech of the gun. There is an armoured hoist that affords some support, but, speaking generally, the gun is more or less at the mercy of shell bursting underneath it.
The Hashidate was built from the same designs at Yokosuka, and is practically identical with the Itsukushima, save that the battery guns aft are in small unarmoured sponsons, and obtain thereby a slightly greater angle of fire. She is further distinguished by a red band; the Itsukushima, being the first of the class, has, of course, a black band.
Grave doubts were soon entertained as to the seaworthiness of these two ships, and the Matsushima being a little more behindhand than the others, her design was altered. She carries the big gun aft, which makes her a better sea boat. The battery is shifted forward in the main deck. In place of the single 4.7-in. that her companions carry in the stern, the raised fok’s’le of the Matsushima contains two of these pieces, firing through recessed port.
Her small quickfiring armament is also different, there being sixteen 3-pounders.
All three ships have a single tripod mast abaft the funnel, with a couple of tops on it. Each now carries three signal yards.
The Itsukushima was launched on July 11, 1889, and commissioned in Japan in 1891. The Matsushima, launched on January 22, 1890, went out in 1892. The Hashidate was not launched till March 24, 1891, but early in 1893 she was in commission.
It had been hoped that these ships would attain speeds of 17.5 knots; none of them, however, ever reached it.
