The Euro-Fighter is a type of steel roller coaster developed by Gerstlauer. First launched in 2003, the trademark feature of the roller coaster is its beyond-vertical drop, which reaches an angle greater than 90 degrees. Although the majority of Euro-Fighters are custom designed for each installation, every design so far has included the trademark drop. A number of different track elements are possible, including vertical loops, diving loops and barrel rolls. Almost all Euro-Fighter models have a vertical chain-driven lift hill, although LSM launch systems are also available.
