Wirbelwind

A large fast battlecruiser, boasting battleship-sized guns, heavy torpedoes, and MLRS units. It is capitalized on speed to dodge heavy ordnance while still capable to trade punch heavily. Ingame design suggests that some kind of a very large jet turbine is installed and somewhat directly propel the ship.

It's rumoured that their speeds are even higher than the ones of a normal Torpedo (80+knots). It is the very first superweapon the player will face in every storyline.

History
The Empire's first seaworthy superweapon, deployed to attack the retreating U.S. Pacific Fleet from Hawaii. Along with the Archaeopteryx, these two superweapons demolished the fleet, leaving it very vulnerable. The Royal Guard saved the U.S. Pacific Fleet from an enemy fleet. Soon, the gigantic ship was deployed off the West Coast of the U.S. Along with a few destroyer detachments, the ship and those escorts were, after a long battle, destroyed.
