Starship V3 Just Cleared Its Final Test — The Biggest Rocket Ever Built Flies Next Month

If you blinked this week, you missed it. SpaceX just lit up the most powerful rocket humanity has ever designed, and the whole thing went off without a hitch.

Tuesday, April 14. Starbase, Texas. Ship 39 — the upper stage of the brand-new Starship V3 — fired six Raptor 3 engines at full power for a full-duration static fire. First time ever for the V3 hardware. No abort. No anomaly. Just clean, controlled fury on the test stand.

Which means one thing: Flight 12 is on.

SpaceX shared the footage the next morning, and it is glorious:

Teslarati broke down what just happened and why it matters:

SpaceX achieved a major milestone on April 14: “SpaceX completed a full duration of Starship V3 today clearing the path for Flight 12.” This test represented the final critical ground verification before the vehicle’s maiden flight.

The booster in question, Booster 19, had undergone earlier testing in March with a partial engine firing. After receiving the remaining engines for full capacity, the vehicle returned for comprehensive evaluation. All 33 Raptor 3 engines firing simultaneously generates approximately 9,240 tons of combined thrust, more than any rocket in history.

Regarding launch timing, Musk previously indicated Flight 12 would occur “4 to 6 weeks away” from early April, making late May a probable window. A successful full-duration static fire is the last major ground milestone before launch.

Let that sink in. 9,240 tons of thrust. More than any rocket that has ever lifted off the face of this planet. Saturn V? The rocket that took humans to the Moon? Not even close.

Space.com zoomed out on the full V3 upgrade:

The new version is expected to bring meaningful improvements over V2 in thrust, payload capacity, and reusability margins. The upcoming mission, designated as Starship’s 12th integrated flight test, will be the debut of the v3 configuration, featuring a taller Super Heavy Booster and Starship upper stage.

The changes SpaceX has made with the v3 rocket and booster are an increased propellant capacity and the more powerful Raptor 3 engines. Raptor 3 engines deliver significantly more power while reducing weight and production costs compared to earlier variants.

This is the Mars rocket. Not a concept, not a render — a real, physical, fully-fueled Mars rocket sitting on a launch pad in South Texas. And if everything holds, we get to watch it fly next month.

Raptor 3 alone is the kind of engineering leap that comes along once a generation. Nearly double the thrust of the original Raptor 1. Lighter. Cheaper. Thirty-three of them stacked in one booster, pumping out enough force to send a 5,000-ton vehicle screaming into orbit.

The best part? Each flight only teaches them more. Every Starship launch so far has pushed reusability, catch mechanics, and heat shielding further than any rocket program in history. Flight 12 will push it further still.

If you’ve been waiting for the moment the Mars timeline stops being a meme and starts being a countdown — this is it. Clear your calendar for May.
