Move over, Shark Week—Japan Airlines (JAL) is making waves with a new innovation inspired by our ocean’s sleekest predator. The airline has introduced a shark-skin-inspired riblet-shaped coating to its Boeing 787-9 aircraft. It’s slick, sustainable, and all about cutting emissions and fuel costs. Forget shark attacks—this is a shark assist!

Shark Skin on a Plane? Tell Me More!
This isn’t some wacky sci-fi plot. JAL, with a little help from the Japan Aerospace Exploration Agency (JAXA) and Orwell (the brainy paint wizards, not the dystopian author), has developed a coating inspired by the fine grooves in shark skin. These riblet-shaped grooves minimize drag by working with the airflow, helping the plane slice through the skies like a great white chasing dinner.
And the numbers? JAXA says this biomimicry reduces surface friction by 5%—that’s not just a science flex; it’s a game-changer for long-haul flights.
The Secret Sauce: Orwell’s Paint-to-Paint Method
You might be picturing someone slapping decals on a plane and calling it a day. Not so fast! This is no DIY craft project. Orwell’s Paint-to-Paint method uses a water-soluble mold to etch those riblet grooves directly into the aircraft’s paint job. The result? A lightweight, durable coating that won’t peel mid-flight. (Because let’s face it, no one wants their plane shedding mid-air.)
Big Impact, Small Grooves
So, what’s all this effort getting us? For starters, JAL has coated 30% of a Boeing 787-9’s fuselage in riblet glory. The result: 0.24% less drag during cruising. Doesn’t sound like much? Think again. That tiny tweak saves 119 tons of fuel annually on the Tokyo/Narita-Frankfurt route alone. That’s 381 fewer tons of CO2 in the air—roughly the same as planting 22,000 trees or banning every leaf blower in Tokyo for a year.
From Test Runs to Long-Haul Heroes
This isn’t JAL’s first swim with shark-inspired tech. Back in 2022, they tested it on a Boeing 737-800 to make sure it could handle real-world conditions (and, presumably, passengers who forgot to put their phones on airplane mode). With those tests aced, they’ve now unleashed this tech on their long-haul fleet.
And starting this January, JAL will test it on international routes. If all goes well, riblet technology could roll out across the fleet, making JAL the apex predator of sustainable aviation.
What’s Next for Aviation?
JAL’s shark-tech initiative isn’t just about looking cool (although it does). It’s about setting a new standard for sustainability in aviation. Airlines worldwide are diving into innovations to reduce emissions, but JAL’s partnership with JAXA and Orwell puts them ahead of the pack—or rather, the school.
Of course, there are challenges. Applying the coating is a labor-intensive process requiring skilled technicians, and industry-wide adoption will need regulatory buy-in. But when the payoff is fewer emissions, lower fuel bills, and a greener planet, it’s worth every groove.
Flying Greener, One Riblet at a Time
So, next time you’re boarding a JAL flight, take a moment to appreciate the high-tech shark-skin vibes of the plane you’re stepping into. It’s not just a feat of engineering—it’s a step toward making air travel as eco-friendly as possible.
Japan Airlines Goes Sustainable with Riblet Coating
Because if sharks can inspire us to fly smarter, maybe they deserve a little less bad press. Who knew aviation’s biggest ally was swimming in the ocean all along?
