Fortified Fleet

Fortified Fleet is the Imperial upgrade, which can be accessed via Top Secret Protocol menu.

This upgrade can give the pure nava Imperial units (Yari Minisub, Sea Wing/Sky Wing, Naginata Cruiser, Shogun Battleship) 25% additional armor, 25% additional speed, and 25% additional vision. Affected units also have the flag of Empire painted prominently on them.
