As the war in the South Pacific turned in favour of the Allies, Albion found itself with a new need for a land-based aircraft with ranges capable of covering the vast distances between Pacific islands. For the most part, Commonwealth-built aircraft were built for the tight confines of continental Europe, with neither the Spitfire nor the newer Hawker Tempest capable of making it farther than 1,000 kilometres from base on internal fuel on a reliable basis. While the country had utilized the P-51 Mustang to some extent, buying additional American aircraft was politically unpalatable to politicians in Columbia and Calapooya, who sought to make the most of the country's suddenly-booming military aircraft construction sector.
