The requirement for the "Kriegsmarine" to divide its 35% tonnage ratio by warship categories had the effect of forcing the Germans to build a symmetrical "balanced fleet" shipbuilding program that reflected the UK's priorities. Since the Royal Navy's leadership thought that the "balanced fleet" would be the easiest German fleet to defeat and a German "guerre-de-course" fleet the most dangerous, the agreement brought the UK considerable strategic benefits. Above all, since the Royal Navy did not build "pocket battleships", Chatfield valued the end of the "Panzerschiff" building.
