Design
The ships of the class were 86.2 metres (282 ft 10 in) long, had a beam of 14.33 metres (47 ft 0 in), a draught of 5.23 metres (17 ft 2 in), and had a displacement of 3,464 ton. The ships were equipped with 2 shaft reciprocating engines, which were rated at 4,700 ihp (3,500 kW) and produced a top speed of 16 knots (30 km/h).
The ships had belt armour of 6 in (15 cm) and 9.5 in (24 cm) barbette armour.
Armament
The main armament of the ships consisted of three 21 cm A No. 1 guns. Two of these were placed in a Barbette on the bow. The third was behind a shield on the stern.[1] These were second hand guns re-used to economize, while the newer 21 cm A No. 2 gun used on HNLMS Koningin Wilhelmina der Nederlanden was already available. This led to sharp criticism.[2] The 21 cm A No. 1 gun was a 21 cm L/35 Krupp gun first built in 1882. The 9 guns required were taken from 9 gunboats instead of buying 9 new 21 cm A No. 2 guns. The 21 cm A No. 2 was a newer model of the Krupp gun, had the same length (L/35) and was only 700 kg heavier, but had about 10% more penetrative power at 2,000 m.[3]
Secondary armament included two single 15 cm (5.9 in) guns and six single 7.5 cm (3.0 in) guns.
