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 that opened as the tallest and fastest roller coaster in the world on May 21, 2005. It is also the second-ever strata coaster, a roller coaster taller than 400 feet (120 m); Top Thrill Dragster was the first and previously held both records. Intamin subcontracted Stakotra to assist with construction.[1]

The train is launched by a hydraulic launch mechanism, accelerating to 128 miles per hour (206 km/h) in 3.5 seconds.[2] 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.[3] While Kingda Ka is still the tallest, its speed record was broken by Formula Rossa when it opened at Ferrari World in 2010
