and raw materials and to launch Plan Z to build a colossal "Kriegsmarine" of 10 battleships, 16 "pocket battleships", 8 aircraft carriers, 5 heavy cruisers, 36 light cruisers and 249 U-boats by 1944 purposed to crush the Royal Navy. Since the fleet envisioned in the Z Plan was considerably larger than allowed by the 35:100 ratio in the agreement, it was inevitable that Germany would renounce it. Over the winter of 1938–39, it became clearer to London that the Germans no longer intended to abide by the agreement, which played a role in straining Anglo-German relations. Reports received in October 1938 that the Germans were considering denouncing the agreement were used by Halifax in Cabinet discussions for the need for a tougher policy with the "Reich". The German statement of 9 December 1938 of intending to build to 100% ratio allowed in submarines by the agreement and to the limits in heavy cruisers led to a speech by Chamberlain before the correspondents of the German News Agency in London that warned of the "futility of ambition, if ambition leads to the desire for domination".
