The Sea-Wing/Sky-Wing is a unique unit in the Imperial arsenal. It is a powerful ground attack aircraft equipped with quadruple plasma relays, far more advanced than the crude Axis or the tested and tried Allied aircraft. It attacks by flying circles around its target, much like dogfighting. The most important aspect of the Sky-Wing is its ability to transform into an anti-aircraft submarine, the Sea-Wing. This makes it nearly invulnerable to most attacks.
