Waterpark operator Hawaiian Falls will open a Torpedo-branded thrill ride at each of its three Texas waterparks in Garland, The Colony and Mansfield this year.
The Torpedo, designed by Whitewater West, will feature two speed slides coming off a four-storey tower.
Riders will step into a capsule at the top of the ride before a hatch will open under their feet, turning them into human torpedoes as they free fall at speeds up to 40 mph down the slide.
Hawaiian Falls will be the first waterpark in the world to install the Torpedo ride and expects to break ground on the new rides before Easter.
The installations are part of a US$2.6m (£1.6m, €1.8m) investment programme into the Hawaiian Falls portfolio of parks.
