Raptor 3: The Most Advanced Rocket Engine Ever Raptor 3 is SpaceX’s latest evolution — the best rocket engine ever made. Key upgrades: • No external heat shield (full regenerative cooling) • Record thrust-to-weight ratio • Simplified design with fewer parts for faster production & higher reliability Elon Musk: “Raptor 3 engine is a very advanced engine, by far the best rocket engine ever made.” It powers Starship V3/V4 toward 10,000+ tons thrust and rapid reusability — the key to Mars.

Elon: Raptor 3 skips the base heat shield entirely “Raptor 3 is designed to require no base heat shield, saving a lot of mass on the bottom and actually improving reliability. So that if, for example, there is a small fuel leak from the Raptor engine, it will simply leak into the existing flaming plasma and not really matter.”

Flashback to July 2022: Elon Musk showing Everyday Astronaut the massive leap from messy Raptor 1 (‘Christmas tree’ vibes 😂) to clean Raptor 2 – 230 tons thrust at 300 bar, tons of parts deleted! Fast-forward to 2026: We’re already on Raptor 3 – 280+ tons thrust, even simpler design, no external pipes, in production (100+ built!), testing like crazy, set for Starship V3 flights soon. Insane progress in ~3.5 years!

One of the most underrated things about Starship isn't just that it's bigger It's that it's designed to completely rewrite the economics of spaceflight SpaceX, Falcon's reusability already removed roughly 85% of the historic cost of launching to orbit Starship aims to deliver another order-of-magnitude improvement on top of that And it's not just about cost.....It's also about throughput Falcon Heavy can deliver up to 64 metric tons to orbit Starship Version 3 is targeting roughly 100 metric tons to orbit Future versions could potentially push that to around 200 metric tons The philosophy behind all of this comes from the Elon's "The Algorithm": 1. Question the requirements 2. Delete parts and process steps 3. Simplify 4. Accelerate 5. Automate You can see this philosophy perfectly in the evolution of the Raptor engine What began as a complex engine evolved into Raptor 3 dramatically simplified, more powerful, more reliable, and easier to manufacture This is how SpaceX keeps pulling ahead Not by adding complexity......By relentlessly removing it

Raptor 3 is a beast! Testing a Raptor 3 engine doing what it would do during a Starship V3 launch. SpaceX is running different versions of this test to make sure the three center engines can handle all the conditions they’ll face on the way up.

ELON: STARSHIP V3 HAS ALL THE INGREDIENTS TO MAKE LIFE MULTIPLANETARY “Starship version 3 is really the version that, I think, achieves all of the key elements. Generally, with any new technology, it takes three major iterations to have it really work well. And with Raptor 3, Starship and Booster version 3, it should be able to achieve being a rapidly reusable reliable rocket with orbital refilling. Basically all of the ingredients necessary to make life multiplanetary will be achieved with version 3 of Starship, which we're aiming to launch for the first time at the end of this year.” Source: SpaceX Update, May 2025

.Elon Musk’s reaction to Starship Flight 5 booster catch. Flight 6 is just over a week away with another booster catch, but also with new objectives like the first ever Raptor engine in-space relight. If the relight is successful, it’ll enable orbital Starship payload missions.

ELON MUSK: "Raptor 3 engine is very advanced engine, by far the best rocket engine ever made. On liftoff, Starship is generating over 100 gigawatts of power. It's 20% of US, while not exploding. There's thousands of ways it could explode and only one way that it doesn't."
