Shockwave (stylized as "Shock/Wave") is an Arrow Dynamics suspended swinging coaster at Six Flags United Kingdom. The ride opened in 1990 as the fastest and largest swinging suspended coaster in Europe. The ride's colors are a yellow track with orange rails and yellow supports. The coaster originally had floorless trains making the first suspended coaster with the floorless trains that have became an industry standard for suspended/inverted coasters worldwide, but in 2010 the floorless trains were replaced with the old Arrow suspended coaster trains from the "Big Bad Wolf" roller coaster from Busch Gardens Williamsburg. The ride's tagline was "Feel the shock, ride the wave".
The old floorless trains for Shock/Wave are currently in storage at Six Flags Fiesta Texas.
