Santa’s sleigh goes hypersonic in GE Aerospace’s vision of 3,836 mph, 40-minute New York to London flights

Santa’s sleigh is about to break every speed limit imaginable as GE Aerospace dreams up a Christmas Eve upgrade powered by the mighty GE9X.

In this tongue-in-cheek vision of the future, Santa swaps jingling reins for jet thrust and AI wizardry.

Forget drifting silently over rooftops, this sleigh is built for some serious speed.

Even Santa might need flight clearance for this one.

Santa’s sleigh ramps it up a notch

According to GE Aerospace, the new sleigh design was created using exascale supercomputing and generative AI, because nothing says Christmas magic like serious computing power.

The design features three propulsion modes, allowing Santa to switch engines depending on whether he’s cruising, conserving, or absolutely flooring it.

For long-haul reliability, the sleigh can call on a pair of GE9X engines, the most powerful commercial jet engines in the world, delivering a festive 134,300 pounds of thrust each.

For reference, these are the same engines that power the massive Boeing 777X.

When Santa wants to be greener than the Grinch’s complexion, he can engage an ultra-efficient mode inspired by the CFM RISE program.

This setup blends Open Fan architecture with hybrid-electric concepts, letting Santa save energy while still making every stop from Sydney to Stockholm.

Speed is nothing without reliability

But when the clock is ticking and billions of stockings are waiting, there’s the third mode: a dual-mode ramjet that launches the sleigh past Mach 5.

Forget Concorde and its ability to fly from New York to London in under three hours.

At a blistering 3,836 mph, Santa could fly the same distance in just 40 minutes.

Of course, speed is nothing without reliability.

GE Aerospace’s AI-enabled fleet support teams will be monitoring Santa’s sleigh 24/7, ready to predict maintenance needs before an elf even hears a strange noise.

With predictive health monitoring and on-call experts worldwide, Santa won’t be stuck on the tarmac explaining delays to disappointed kids.

As Thomas the Elf (from GE Aerospace) puts it: this Christmas, Santa is faster, smarter, and more efficient than ever.
