Ship project history: Authorised under the Act of 2/3/1889. Intended as a harbour defence ram, she differed from the British Polyphemus to having no torpedo armament.

Ship protection: The 152mm side armour, 76mm at lower edge, was inclined outwards and joined the turtle deck which was 152mm at the edge, then 140mm and 64-51mm at the centre line. The knuckle was backed by 1143mm of timber, and the hull normally 1.5-1.8m maximum above water, was lowered 0.15m for action by water ballast.

Modernizations: None.

Naval service: Katahdin was only commissioned up to April 1897 and again from March to October 1898. Stricken 9/7/1909, she was used as 'Ballistic Experimental Target A' in important firing trials which determined the need for 343mm armour in future battleship designs.
