Kingda Ka

Kingda Ka is a launched roller coaster located at Six Flags Great Adventure in Jackson, New Jersey. Designed by Werner Stengel, Kingda Ka is an Accelerator Coaster model from Intamin, opening as the tallest and fastest roller coaster in the world on May 21, 2005. Kingda Ka is the world's only operating strata coaster (a full-circuit roller coaster taller than 400 feet (120 m)) as of 2022. When it opened, Kingda Ka surpassed the now-closed Top Thrill Dragster, the world's first strata coaster, in both speed and height. The train is launched by a hydraulic launch mechanism, accelerating to 128 miles per hour (206 km/h) in 3.5 seconds. The train climbs the main top hat tower element at the end of the launch track, reaching a height of 456 feet (139 m), before dropping 418 feet (127 m) and completing the course in 28 seconds. While Kingda Ka is still the tallest, its speed record was broken by Formula Rossa at Ferrari World in 2010; however, it remains the fastest coaster in North America.
