'''HNLMS ''Draak''''' (Dutch: ''Draak'') was a monitor (Dutch: ''rammonitor 1e klasse''), built by the ''[[Rijkswerf (Amsterdam)|Rijkswerf]]'' at Amsterdam for the [[Royal Netherlands Navy]] in the late 1870s.

==Design and description==
In early 1875, the Dutch Navy in the home waters consisted of 4 ram turret ships, 10 monitors and 16 gunboats. All but two of these were armed with 23 cm muzzle loading guns. This is probably why the Dutch preferred to stick with the 23 cm gun. When England finally admitted the superiority of breech-loading guns over muzzle-loading guns, the Dutch government followed suit.

The switch from 23 cm muzzle-loaders to 28 cm breech-loaders would have strong effects on the design of Dutch monitors. The contract for the preceding monitor ''Luipaard'', ordered in July 1875, only called for a change to breech-loaders, not to an overall redesign. The result was a monitor nearly identical to the previous ten monitors, but armed with 1 breech-loading 28 cm gun instead of two 23 cm muzzle-loaders.

''Draak'' was designed from the start to balance hull and armament. She was to have two 28 cm breech-loaders. This necessitated a 33% increase in size compared to the preceding ''Luipaard''. The 33% increase in size and equivalent increase in cost, led to double the amount of firepower.

With a displacement of 2156t ''Draak'' was about the same size as the Ram turret ships of the Buffel class and the Schorpioen class. The specific task of ''Draak'' was the defense of the Texel [[roadstead]] and the [[Zuiderzee]]. Therefore she had a draught of only {{convert|3.30|m|ftin|sp=us}}, so she could sail these shallow waters. This shallow draught was compensated by a beam of {{convert|15.0|m|ftin|sp=us}}.

===Propulsion===
The machinery for ''Draak'' was made by the [[Werkspoor#Koninklijke Fabriek van Stoom- en andere Werktuigen| Koninklijke Fabriek van Stoom- en andere Werktuigen]] in Amsterdam. The two machines had a nominal power of 160&nbsp;hp each. They had diagonally placed cylinders that could make 120 moves per minute by 65 English pounds of steam pressure in the boilers.<ref name="RC23071879">{{Cite news |url=https://resolver.kb.nl/resolve?urn=ddd:011005973:mpeg21:p002 |work=Rotterdamsche courant |title=Binnenland |date=23 July 1879 }}</ref>

===Armament===
The main armament of ''Draak'' consisted of two [[28 cm A No. 1]] breech-loaders made by [[Krupp]]. At the time of her construction these were also referred to as 600 pounders.

===Armor===
''Draak'' had a [[Belt armor|belt]] of [[wrought iron]] that ranged from {{convert|204|mm|1|sp=us}} thick, to {{convert|140|mm|1|sp=us}}. The [[gun turret]], was protected by {{convert|230|mm|1|adj=on|sp=us}} armor plates.

==Service==
On 28 June 1879 ''Draak'' left the port of IJmuiden and reached Texel. In July 1879 she was on sea trials in the Texel roadsted. The results were not good. Several parts of the main machinery overheated, and attaining full speed was not possible.<ref name="RC23071879" /> In a new attempt on 14 August she was more successful. She attained the designed speed and other expectations.
