Thunderbird 4
TB41
Type: Submarine
Affiliation: International Rescue
Main Operator: Gordon Tracy
Appearances: List of Appearances

Thunderbird 4 is International Rescue's main vehicle for underwater rescue. It is a yellow mini-submarine, usually delivered to the danger zone by Thunderbird 2 in Pod 4. It is piloted by aquanaut Gordon Tracy.

It fits comfortably within one of Thunderbird 2's pods, usually Pod 4, although on occasion it has been delivered to the danger zone by other means, either by another pod (in Attack of the Alligators!, it is launched from Pod 6), direct launching from Tracy Island, or aided transportation by the World Navy (only seen on one occasion - Terror In New York City - when Thunderbird 2 was undergoing a complete rebuild).

Thunderbird 4 is equipped with a missile launcher, a searchlight, a battering ram and a laser, all of which are located in the nose of Thunderbird 4. It is capable of travelling on surface water (hover mode) or underwater. Its small interior is equipped with an airlock for access and exit while underwater.
