Synopsis:
While gathering intelligence data aboard a small submarine, the Blackhawks find a new Nazi super-sub. The Nazi sub is invulnerable to attack from torpedos. The Blackhawks commandeer another Nazi sub, allowing them to approach the super-sub. They then plant explosives in the cannons of the sub. When the super-sub fires, the explosives detonate and destroy the new weapon.
