Before all nations came together as the United Earth Government, all Nations were at war with each other. There were battles being fought inside the countries that were at war. The United States was one of several allied nations fighting in the conflict. In 1999, the United States Navy Carrier battle group was tracking a Russian Sub in the South Pacific. At the same time an alien ship came out of hyperspace and entered Earth's Atmosphere and flew right over several cities and the Aircraft Carrier USS Kenosha and a fighter squadron led by Roy Fokker. Then it crashed landed on Macross Island.
