HNLMS Stier

HNLMS Stier was a Schorpioen-class monitor monitor built in England for the Royal Netherlands Navy in the 1860s.

Design and description
The Schorpioen-class ships were designed to the same specification, but varied somewhat in details. The dimensions here are for HNLMS Schorpioen, with her British-built sister ship, Stier, being marginally smaller. They were 205 ft long overall, had a beam of 38 ft and a draft of 16 ft. They displaced 2069 - 2175 LT and was fitted with a ram bow. Their crew consisted of 110–136 officers and enlisted men.

Stier was powered by a pair of horizontal trunk steam engines, each driving a propeller shaft using steam from four square boilers. The engines produced 2225 - 2250 ihp and gave the ship a speed of 12 kn. The Schorpioen-class ships carried a maximum of 200 LT of coal that gave them a range of 1030 nmi at a speed of 10 kn. They were also equipped with two pole masts.

The Schorpioens were armed with a pair of Armstrong 9 in rifled, muzzle-loading guns mounted in the gun turret. The ships had a complete waterline belt of wrought iron that ranged in thickness from 6 in amidships to 3 in at the ends of the ships. The gun turret was protected by 8 in inches of armor and the armor thickness increased to 11 in around the gun ports. The base of the turret was also protected by 8 inches of armor and the walls of the conning tower were 144 mm thick. The deck armor ranged in thickness from 0.75 to 1 in.
