Ship project history: These destroyers were built under 1929 ("C" class) and 1930 ("D" class) programs. Development of "A" class, for the account some the bigger dimensions are fuel stowage increased by 20%, new fire control system established and the antiaircraft armaments are strengthened. In order to avoid loss of speed because of the increased displacement machinery power was increased to 36 000hp.

Occurrence of new fire control system led to a enlarging of the superstructure, differing original splitting (chart room, forming director basis, has was on some distance from a bridge.

The antiaircraft 76mm gun as originally appeared should change 40mm pompoms, but in an ultimate variant they remained by the ships, however they have removed from a habitual position between funnels (where now 76mm gun was placed) on a forecastle deck.

In remaining "C" class differed few from the predecessors. By analogy to "A" class they received minesweeping equipment to the detriment of anti-submarine abilities, but their a little bigger dimensions allowed to have sonar.

Leader Kempenfelt has continued originated in 1928 on "B" class tendency to standardization of the leader and destroyers and had a little bit increased aft superstructure with additional premises for a headquarters of the flotilla commander. The anti-submarine and minesweeping equipment were not established for the purpose of loads decrease.

Only 5 of planed 9 ships of "C" class have constructed, in connection with the economic crisis which has burst in 1929 building of four had cancelled.

The ships of the 1930 program ("D" class) were  built on the same design as "C", difference consisted in strengthening of anti-submarine arms at the expense of removing of the minesweeping equipment and installation on part of the ships of 12.7mm quadruple machine guns instead of 40mm pompoms. Pompoms on "C" class are on a forecastle deck, on "D" class their place had chosen to the increased bridge wings leaning against massive steel pipes. The superstructure without exotic "splitting" became last feature.
