| Summary | A Japanese commercial solid-fuel small launcher that has failed on all three flight attempts through March 2026, putting its commercial viability in serious question. | Largest and most powerful rocket ever flown. Super Heavy booster uses 33 Raptor engines. V3 Ship debuted on Flight 12 (May 22, 2026) from Starbase Pad 2 — it reached space but broke up at the ocean surface, and the vehicle is grounded pending an FAA mishap review. Mechazilla booster catches demonstrated from Flight 5 (Oct 2024) onward; first payload deploy on Flight 10 (Aug 2025). Primary vehicle for the Artemis HLS lunar lander (Artemis III LEO docking demo 2027, first landing on Artemis IV). | The world's most commercially active small launch vehicle, designed and built in-house at Rocket Lab. Rutherford engines are the first flight-proven engines made with additive manufacturing (metal 3D printing). Booster recovery via parachute and helicopter catch (later transitioned to ocean recovery). |
