In the late 1930s the government changed plans and increased the budget for military purchases following the German expansions in central Europe. In 1938, 12 &lt;a href="Fairey%20P.4/34"&gt;Fairey P.4/34&lt;/a&gt;s were to be produced at Orlogsværftet, along with 12 Italian Macchi C.200 fighters. None of these were produced before the German invasion of Denmark on April 9, 1940.
