Due to the length of time required to build warships and the short duration of the agreement, its effect was limited. Experts from the German and British navy estimated that the first year Germany could reach the 35% limit was 1942.  In practice, the absence of shipbuilding land, construction problems, the shortage of skilled labour and the lack of foreign exchange in the purchase of necessary raw materials slowed down the reconstruction of the German Navy. A lack of steel and non-ferrous metals, caused by the fact that the navy was the third highest in German armaments behind the army and air force, meant that the navy (as the German navy had been renamed in 1935) was still far from the 35% limit when Hitler lifted the agreement in 1939.  The Anglo-German Naval Agreement (AGNA) of 18 June 1935 was a naval agreement between Great Britain and Germany that regulated the size of the navy vis-à-vis the Royal Navy. For its part, the German Government considers that the agreement it has reached with Her Majesty`s Government in the United Kingdom and which it considers to be a permanent and definitive agreement with effect from today between the two Governments will facilitate the conclusion of a general agreement on this issue between all the maritime Powers of the world. The Helgoland-Zanzibar Treaty (also known as the Anglo-German Agreement of 1890) was an agreement signed on 1 July 1890 between the German Empire and Great Britain. At the Munich Conference, which culminated in the Munich Agreement in September 1938, Hitler informed Neville Chamberlain that while UK policy was able to “make it clear in certain circumstances” that the UK could intervene in a war on the European continent, the political terms of the agreement no longer existed and Germany would have to denounce it. This is how Chamberlain mentioned it in the Anglo-German declaration of September 30, 1938.  The Naval Pact was signed in London on June 18, 1935, without the British government discussing with France and Italy, or later informing them of the secret agreements that provided that the Germans could build more capable warships in certain categories than any of the three Western nations that then possessed. The French saw this as a betrayal. They saw in it a new appeasement of Hitler, whose appetite for concessions grew.
