Stage: Keel Naval Port, Germany
The Graf Zeppelin is a massive craft which launches smaller vehicles and shoots fireballs from its turrets. After taking some damage, the deck falls away revealing the innards of the ship, as well as some small tanks.
Despite its name, the Graf Zeppelin is not a zeppelin airship; instead, it is a German aircraft carrier named for the airship's inventor. The real carrier was launched but never completely constructed or made operational .
