The ships of the class were 96.62 metres (317 ft 0 in) long, had a beam of 15.19 metres (49 ft 10 in), a draught of 5.82 metres (19 ft 1 in), and had a displacement of 5,002 ton.[2] The ships were equipped with 2 shaft reciprocating engines, which were rated at 6,500 ihp (4,800 kW) and produced a top speed of 16.5 knots (30.6 km/h).[2] In addition, the machinery had two sets of triple expansions.[3]
Armor
When it came to naval armour all three ships were equipped with Krupp armour.[3] The ships had belt armour of 6 in (15 cm), 10 in (25 cm) barbette armour and 10 in (25 cm) turret armour.[2] Deck armour of the Koningin Regentes class was 2 in (5.1 cm).[4]
A small improvement over the preceding Evertsen class was that the 15 cm guns were now also protected by decent shields, instead of having only 12 mm armor protection.[5]
Armament
The artillery of the Koningin Regentes class was a big step forward in comparison with the smaller Evertsen class.[5] The main and secondary battery were now all L/40 long quick firing guns.[6] Some applauded the minister for this choice of armament.[5]
The main armament of the ships were two 24 cm SK L/40 guns in single turrets.[5][2] In fact, the German Navy used the same gun as main armament on their newest battleships of the Kaiser Friedrich III class. The quick fire capability of this gun meant that it fired about three rounds a minute. This made the difference with the 21 cm guns of the Evertsens even bigger.
Secondary armament included four single 15 cm (5.9 in) guns[4] This was also an improvement over the two 15 cm quick-firing guns of the Evertsens, which were also shorter. There were eight 7.5 cm (3.0 in) No. 3 single guns.The ships had three 45 cm (18 in) torpedo tubes of which two were submerged and one was above water at the bow.[3]
