The Wolf- or Fret-class destroyers, also known as the Roofdier class, lit. "predator",^{[A 1]} 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.^[1]

The ships displaced 510 tonnes (502 long tons) and measured 70.4 metres (231 ft 0 in) in length overall, 6.6 m (21 ft 8 in) in breadth, with a 2 m (6 ft 7 in) draught. They were powered by four Yarrow boilers installed creating steam that produced 8,500 horsepower (6,300 kW). They had two Krupp-Germania steam turbines that drove two shafts. The first four ships, Wolf, Fret, Bulhond, and Jakhals, each carried 120 t (120 long tons; 130 short tons) of coal, the last four, Lynx, Hermelijin, Vos, and Panter, carried an additional 12.5 t (12.3 long tons; 13.8 short tons) of fuel oil in addition to the 120 t of coal. This gave the last four ships an additional 340 nautical miles (630 km; 390 mi) of endurance.

The ships were armed with four 75-millimetre (3 in)/52-calibre guns, four 7.92 mm (0.31 in)/80-calibre machine guns, and two 450 mm (18 in) torpedo tubes.

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.
