Sea Wing

0
Sea-Wing is an anti-air sub mainly used for air defense for Imperial fleets, while the Sky-Wing is a close air support plane that is useful for taking out groups of infantry. However, it lacks the firepower to pierce the heavy armor of tanks and ships.
The Wings are not without their flaws, since they are vulnerable to whatever they cannot target. When airborne, anything that isn't infantry can and will destroy it quickly, particularly air superiority fighters. While underwater, it cannot safely operate without escort from some Naginata cruisers, as it only provides air defense, and while being a submarine does have its perks, it falls very easily to enemy vessels, many of which can target them directly.
