"The British planes are doomed. Heligoland is surrounded by ships with artillery designed to swat your bombers from the sky. Like insects. Oh, I'm afraid the island defenses will be quite operational when your friends arrive."
Zerstörers appear once the player reconstructs the radio and broadcasts a message to call in a bombing run to destroy the island. Afterwards, the German destroyers will appear off the coast, visable from the Artillery Bunker and Overlook areas. The German destroyers are armed with special anti-air artillery guns to defend Heligoland from the bombers of the Royal Air Force, meaning the player must destroy them if they are to complete the mission. To do this, the player must use a coastal artillery cannon in the Artillery Bunker, which can be activated once the player is able to successfully escort the Artillery Loader to the bunker. The player must now angle the cannon to destroy the three ships. Once all three ships are sunk, it will bring the player once step closer to destroying the island.
