From the preview:
From the other side of the Atlantic Ocean the American Alliance transports endless armies in their Light Carriers to hunt Creatures wherever they are and to protect their land wherever they need to.
The Curtis P6 Appaloosa is a compact fighter designed to be transported in the flying American carriers. The Curtis P6 is the main American fighter and it is manufactured by hundreds. Small in size and a very practical design make the Curtis P6 a reliable ride and a dreadful enemy, especially in large numbers.
