The U-42 Pottwal
A new type of submarine aircraft carrier that has just been launched in an underground test pool. It is not a very large ship, but it carries a large number of missiles and combat pods. The bridge is a special design that can be launched separately and used as an attack aircraft on its own.
Destroying the core on the bridge will disable the entire ship, but destroying the body first will allow the bridge unit to separate and begin flying. Destroying the flying bridge unit will reward an S. Bonus, and release the Juno mounted within.
