In the mid-thirties, in connection with growth of threat from Japan, the Dutch Government has found means for building of 4 modern destroyers. As commissioned destroyers of "Admiralen" type have been insufficiently armed, for new ships the thrust became on increasing of dimensions and fire power, and it dared, not in the last instance, at the expense of advanced fire control system and qualitative enhancement of air defence weapons. Gerard Callenburgh and Tjerk Hiddes have been ordered under the 1937 program, Isaak Sweers and Philips van Almonde next year.
Gerard Callenburgh class destroyers were again projected by means of Yarrow and had increased approximately on 300t displacement. Increased dimensions have allowed to strengthen armament by one more 120mm gun, and also for the first time in Dutch fleet to mount quadruple 533mm TT. Artillery took places under the original scheme: fore and aft there were twin turret mounts (with placing of guns in common gun slide), and single gun mount on a stern superstructure. As well as in the previous designs, ability of carrying of a seaplane was kept, seaplane was placed between funnels not to eclipse fire angle of aft 40mm MG and a derrick for seaplane handling was installed at fore funnel.
Engine power in comparison with previous "Admiralen" type has increased by 45%; the endurance also was significantly increased. On trials Isaak Sweers has shown 37.5kts speed.
Isaac Sweers 10-12.5.1940 was been towed off to the Great Britain and was completed by Thornycroft at Southampton under the changed design. Incomplete Gerard Callenburgh was scuttled at Rotterdam 15.5.1940; she was salvaged by German wreckers 17.7.1940 and after repair 11.10.1942 was commissioned by Kriegsmarine as ZH1, she was lost 9.6.1944. Incomplete Tjerk Hiddes was scuttled 14.5.1940; she was salvaged by German wreckers 12.6.1940, renamed ZH2, but never completed and later scrapped. Philips van Almonde was blown up on a slipway 17.4.1940 (under some sources she received German name ZH3).
1942, Isaac Sweers: - 2 x 4 - 12.7/62; + 4 x 1 - 20/70 Oerlikon Mk II/IV
Isaac Sweers was sunk 13.12.1942 by German submarine U431 at coast of Algeria.
