In 1914, the assassination of Archduke Franz Ferdinand triggered a series of events which launched the world into the Great War. For four years, the United States have remained aloof, isolated by the expanse of the Pacific Ocean and its own Great White Fleet. In the absence of assistance from abroad, Great Britain has been battered by the every growing fleet of the German Empire’s Wehrzeppelins, massive airships which dominate the skies over Europe and rain death in massive, prolonged bombing attacks. In 1917, the British Intelligence Agency passed news on to the United States that the German Empire had begun researching a means to build Wehrzeppelins capable of trans-atlantic attacks. Contentedly disengaged until now, the United States began a frantic push to muster an army, and even more, to develop its own technology to counter the Wehrzeppelin.
