| Summary | NASA's human deep space launch vehicle for the Artemis programme. Uses heritage RS-25 shuttle main engines (4 per flight, expended). Block 1B with Exploration Upper Stage cancelled Feb 2026; Block 1 will fly through Artemis IV at minimum. | 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). | A family of medium-lift launchers from SAST serving China's growing SSO/LEO commercial and government satellite demand, with the 6A and 6C variants adding solid boosters or a simplified expendable configuration respectively. |
