HELP

Stealth is a steel launched roller coaster located at Thorpe Park in Chertsey, Surrey, England, UK. It is the second fastest roller coaster in the United Kingdom and the third tallest, after The Big One at Pleasure Beach Resort, which opened in 1994, and Hyperia also at Thorpe Park, which opened in 2024.

The attraction is an Accelerator Coaster installation from Intamin and was designed in conjunction with Ing.-Büro Stengel GmbH. Stealth was installed by RCS GmbH.^[1]

With the closure of Do-Dodonpa in 2021, Stealth is now the fastest accelerating roller coaster.

History

Stealth opened to guests on 15 March 2006, a year after Rita at Alton Towers.

Originally specified to have an acceleration of 0-128.7 km/h in 2.3 seconds,^[2] for the 2024 season the entrance signage was updated with a new acceleration of 0-128.7 km/h in 1.8 seconds.^[3]

Design

Elements
Hydraulic launch from 0 to 128.7 km/h in 1.8 seconds 62.5 metre top hat (Outside) Hill

Using hydraulic technology, the train is launched from 0 km/h to 128.7 km/h in 1.8 seconds. Following the launch, the train rises up and over the 62.5 metre tall top hat. This is followed by an airtime hill, which leads into the final brakes.

Stealth has a transfer track, which is located in a warehouse beside the ride.

Trains

3 trains with 5 cars per train. In each car, riders are arranged 2 across in 2 rows, for a total of 20 riders per train.

Similar rides

Stealth has a very similar layout to Kingda Ka, which opened in 2005 at Six Flags Great Adventure, but is a little less than half the size. A clone of Stealth, Zaturn, at Space World, opened in April 2006 and operated until the closure of the park in December 2017.
