Stealth is a steel roller coaster built by Intamin of Switzerland. The coaster is located in the Amity Cove area of Thorpe Park in Surrey, England, UK and opened in 2006. The ride reaches a maximum height of 62.5 m (205 ft). When the ride opened in 2006 it previously accelerated from 0-80 mph in 1.9 seconds, but in 2010 the trains were upgraded and stripped of weight to enable it to accelerate from 0-80 mph in 1.8 seconds (an acceleration of approximately 2G). It is the fastest accelerating and also the tallest launch coaster in the UK. It also has the fastest acceleration time on any roller coaster in Europe. At the base of the top hat on each side, G-forces of up to 4.7G are produced.
