Thunderbirds Are Go is a science fiction television programme produced by ITV Studios and Pukeko Pictures. It uses a combination of computer-generated animation and live-action models. It is a remake of the series Thunderbirds created by Gerry and Sylvia Anderson which follows the exploits of International Rescue (IR), a rescue organisation run by the Tracy family out of their secret island base in the Pacific Ocean. They use technologically-advanced craft for land, sea, air and space rescues in their operations, the most important of which are a set of vehicles called the Thunderbirds, piloted by the five Tracy brothers.

Thunderbirds is a British science fiction television series created by Gerry and Sylvia Anderson, filmed by their production company AP Films (APF) and distributed by ITC Entertainment. It was made between 1964 and 1966 using a form of electronic marionette puppetry combined with scale model special effects sequences. Two series, totalling thirty-two 50-minute episodes, were filmed; production ended with the completion of the sixth episode of the second series after Lew Grade, the Andersons' financial backer, failed in his bid to sell the programme to American network television.
