Wolf-class destroyer

The Wolf- or Fret-class destroyers, also known as the Roofdier class, lit. "predator", were a class of eight destroyers that were built between 1910 and 1913 for the Royal Netherlands Navy to serve in the Dutch East Indies. They were the first Dutch destroyers built after a British design. The first six ships were built by Koninklijke Schelde Groep De Schelde shipyards in Vlissingen, and the last two by Fijenoord in Rotterdam. The ships were replaced at the end of the 1920s by the Admiralen-class destroyer.

Design
The ships displaced 510 t and measured 70.4 m in length overall, 6.6 m in breadth, with a 2 m draught. They were powered by four Yarrow boilers installed creating steam that produced 8500 hp. They had two Krupp-Germania steam turbines that drove two shafts. The first four ships, HNLMS Wolf, HNLMS Fret, HNLMS Bulhond, and HNLMS Jakhals, each carried 120 t of coal, the last four, HNLMS Lynx, HNLMS Hermelijin, HNLMS Vos, and HNLMS Panter, carried an additional 12.5 t of fuel oil in addition to the 120 t of coal. This gave the last four ships an additional 340 nmi of endurance.

The ships were armed with four 75 mm/52-calibre guns, four 7.92 mm/80-calibre machine guns, and two 450 mm torpedo tubes.

Ships
They are named after mammals of the order Carnivora (Roofdieren is a synonym for carnivore in Dutch). Their names in English, in the sequence listed, mean: wolf, ferret, bulldog, jackal, ermine, lynx, fox and panther.
