The Federal Warbirds was a special FRONT LINE issue published in April 2004. It focused on Osea and Yuktobania.[1] Below is a translation of the original Japanese text.[2]


The Osean Federation and the Union of Yuktobanian Republics, separated on opposing ends of the ocean. These two superpowers have always regarded each other as the "potential enemy" and have raced for arms expansion and global influence. The same line of evolving strategies that led to the development of ICBMs and SDI has brought about great tension across the world.

After the last great war, the two countries went on the path of improving diplomatic relations with economic activities and cultural exchange being the primary focuses. However, due to ideological differences, social movements within and conflicts between the two nations' allies have not disappeared. The establishment of a new world order for this era is needed.
