Gerard Callenburgh design tradeoffs

The Netherlands was not bound by the naval treaties, yet the Gerard Callenburgh design grew only about 300 tons over the decade-older Admiralen class. Its specification combined 37.5-knot speed and a 3,200-nautical-mile range at 15 knots with five 120 mm guns in two twin mounts and one single mount. Eight 21-inch torpedo tubes, machine guns, mines, and depth charges completed the general armament. Its strongest advantage was four radar-directed 40 mm guns in the Dutch system associated with the later Allied Hazemeyer mounting. The criticism of the design is that a navy with so few ships and so many commitments needed something closer to a Tribal or French contre-torpilleur in size and hitting power. Its improvement against other destroyers was modest, and its theoretical one-on-one advantage remains doubtful in this assessment. Speed helped, but short-range destroyer brawls could require ships to slow down, making firepower at least as important.
