It’s the sound that gets you first. That rhythmic, mechanical hiss of hydraulic fluid building pressure behind a massive winch. You’re sitting there, staring at a horizontal stretch of track that looks way too short for what’s about to happen. Then, a voice—sometimes bored, sometimes overly dramatic—cracks over the speakers: "3, 2, 1, GO GO GO!"
Before your brain can even process the word "go," your internal organs have basically moved to the back of your ribcage.
Stealth at Thorpe Park isn't just a roller coaster. Honestly, calling it a "ride" feels a bit like calling a fighter jet a "plane." It’s an engineering marvel that has dominated the Surrey skyline since 2006, and despite the arrival of bigger, loopier attractions like Hyperia, Stealth remains the undisputed king of the "blink and you'll miss it" adrenaline rush.
The Ridiculous Physics of the Launch
Let’s talk numbers, because the math here is actually insane. Stealth isn't powered by gravity or a traditional chain lift. It uses a nitrogen-pressurized hydraulic launch system designed by Intamin, the same Swiss geniuses behind Kingda Ka and Top Thrill Dragster.
You go from 0 to 80 mph in 1.9 seconds.
To put that in perspective, a Tesla Model S Plaid—one of the fastest accelerating production cars on the planet—takes about 2.1 seconds to hit 60 mph. Stealth beats that while carrying a train full of 20 screaming people. The acceleration forces you're feeling? About 4.5G. That’s more than what astronauts feel during a Space Shuttle launch.
Why the "Top Hat" is a Psychological Trap
Once you’ve survived the initial blast, the track kicks you skyward at a 90-degree angle. This is the "Top Hat." You’re staring straight at the clouds, then suddenly, you're 205 feet in the air. For a split second at the very peak, there’s this weird, eerie silence where the train almost seems to stop.

It’s called "airtime."
Then, the drop. It’s a vertical plunge with a 90-degree twist. If you’re in the back row, you get whipped over that crest with terrifying speed. If you’re in the front, you get the unobstructed view of the concrete coming at you very, very fast.
What Most People Get Wrong About Stealth
A lot of casual visitors think Stealth is "too short" to be worth the wait. "It’s only 20 seconds long," they say.
Technically, they’re right. From the moment the catch-car hooks onto the train to the moment you hit the magnetic brakes, you’re looking at a ride time that is shorter than a TikTok video. But that’s missing the point. Stealth is a drag race, not a marathon. It’s designed to provide a specific, high-intensity shock to the nervous system that longer coasters like The Swarm or Colossus just can’t replicate.
The Infamous Rollback
There is one thing every Stealth fan secretly hopes for: the rollback.
Because the ride relies on a precise balance of hydraulic pressure and wind resistance, occasionally the train doesn’t quite have enough "oomph" to make it over the 205-foot peak. When this happens, the train stalls at the top and rolls backward down the 90-degree spike.

Don't panic. It's safe.
The track is equipped with magnetic brake fins that pop up the moment the train passes them. If the train comes back down backward, these fins slow it down to a gentle halt. It’s actually the rarest "achievement" for a UK coaster enthusiast. If you experience a rollback, you basically won the Thorpe Park lottery.
The Evolution of Stealth at Thorpe Park
When the ride opened in 2006 in the "Amity Speedway" section of the park, it was a massive gamble. The park needed a "statement" piece to compete with Alton Towers. Initially, the ride had a slightly different aesthetic, but it has always leaned into that 1950s Americana drag-racing vibe.
The area surrounding the ride—Amity—is themed after a 1950s town hit by a tidal wave. It sounds grim, but it works. The contrast between the retro, kitschy diners and the high-tech, screaming white track of Stealth is iconic.
Maintenance: The Silent Hero
You might notice Stealth closes more often than other rides when the weather turns. That’s not because it’s "broken." Hydraulic launches are incredibly sensitive to temperature and wind speed. If the fluid is too cold, it becomes more viscous, affecting the launch speed. If the wind is blowing too hard against the Top Hat, the computer might decide the risk of a rollback is too high.
Engineers at Thorpe Park spend hours every morning testing the "catch-car"—the device that pulls the train—to ensure the tension is exactly right. It’s a high-maintenance beast, but that’s the price you pay for 80 mph in under two seconds.

How to Actually Ride Stealth (The Pro Tips)
If you want the best experience, you have to be strategic.
- The Front Row: If the queue for the front row is under 30 minutes, do it. There is nothing like the feeling of 80 mph wind hitting your face with no train structure in your field of vision. It feels like flying. Or falling. Mostly falling.
- The Back Row: This is for the "airtime" junkies. Because the train is so long, the front of the train is already halfway down the drop by the time the back row reaches the peak. This means the back row gets "yanked" over the top, resulting in a much more intense feeling of weightlessness.
- The "Greyout": Some riders experience a brief "greyout" during the initial launch or at the bottom of the first drop. This is just the G-force pulling blood away from your head. It’s temporary, but if you’re prone to it, keep your head back against the headrest and stay hydrated.
Stealth vs. Hyperia: The New Rivalry
In 2024, Thorpe Park opened Hyperia, the UK's tallest and fastest roller coaster. Naturally, everyone started asking: is Stealth still relevant?
Hyperia hits 80 mph too. It’s significantly taller at 236 feet. But here’s the thing: Hyperia takes a long time to get to that speed. It’s a slow climb up a lift hill followed by a massive drop. Stealth, however, gives you that speed instantly.
They offer two completely different types of fear. Hyperia is about height and sustained grace; Stealth is about raw, aggressive power. Even with the new "big kid" on the block, the queue for Stealth remains one of the longest in the park for a reason. There’s just nothing else that hits your equilibrium quite like a hydraulic launch.
Practical Insights for Your Visit
If you're planning to tackle Stealth, keep a few things in mind to avoid disappointment:
- Check the Weather: If the wind is gusting over 30-40 mph, Stealth is likely to close. Check the Thorpe Park app before you make the trek to the back of the park.
- Loose Items: They are dead serious about this. At 80 mph, a phone flying out of a pocket becomes a lethal projectile. Use the lockers.
- Single Rider Queue: Stealth used to have a very effective single rider line. Check if it’s operational during your visit, as it can cut a 60-minute wait down to 10 minutes if you don't mind sitting next to a stranger.
- The "Pre-Launch" Lean: Keep your head firmly against the headrest before the launch starts. If you lean forward to look at the track, the 4.5G force will slam your head back into the seat, which isn't exactly fun for your neck.
Stealth remains a masterclass in minimalist thrill-seeking. It doesn't need ten inversions or a five-minute ride time. It does one thing—acceleration—and it does it better than almost anything else in Europe. Whether you're a seasoned enthusiast or a terrified first-timer, that 1.9-second blast is something you never quite get used to.
Next time you’re standing in Amity, listen for that hiss. You’ll know exactly what’s coming.
Actionable Next Steps:
- Download the Thorpe Park App: Monitor live wait times specifically for Stealth, as they fluctuate wildly after the morning rush.
- Book an Afternoon Slot: Statistically, Stealth’s reliability improves in the afternoon once the hydraulic fluid has warmed up through repeated cycles.
- Check the Maintenance Schedule: Before traveling, visit the official Thorpe Park "Island Help" website to ensure Stealth isn't scheduled for a planned maintenance closure.
