Synopsis for "Hyrdofoil"
Wild Bill and Airborne transport a new transportable air-sea base with a team of Joes aboard from New Orleans to the Gulf of Mexico. The base is attached to the sunken legs of an old drilling platform and Cobra Commander observes its progress from a submarine. Meanwhile, at the Pit, Hawk interrogates Candy about her father's Cobra work, while Buzzer takes a liking to her. In the Gulf, several cargo containers are released to the surface, while Professor Appel activates a device that kills fish with vibrations.
The containers reveal three Moray hydrofoils that attack the air-sea base, causing a fire that Barbecue manages to put out. Duke and Doc consider the option of a nuclear strike, but instead, they dispatch all aircraft with a full bomb load to neutralize the hydrofoils. The explosives have the same power as a nuke but without the radioactive side-effects. However, the sea bed is affected, and Duke discovers that a faultline has been aggravated, which delights Appel, as it was part of their plan.
At the W.H.A.L.E., Deep-Six discovers an underwater bunker with a revolving electronic dish that Tripwire targets with a flare for the jets. The Cobra Tanker is also discovered, where Appel explains that nothing Candy knows can jeopardize their plan. The Joes are able to neutralize the hydrofoils, but the seismic activity caused by the explosives has put the Gulf of Mexico at risk.
