Context
The Adder class monitors very much resembled the preceding Heiligerlee class. There were some small differences, but the main difference was that the Adder class got a ram, which was very popular after the Battle of Lissa.
Haai would become the first monitor to be built by a private Dutch shipyard.
Armament
Just like the preceding Heiligerlee class, the Adders were armed with two 23 cm Armstrong rifled muzzle loaders. Luipaard differed by having only a single Krupp 28 cm breechloader, known as 28 cm A No. 1.[1]
Later all ships of the class were re-armed with the 28 cm A No. 1, except Adder, which sank beforehand.
