| 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. | Rocket Lab's medium-lift reusable rocket targeting the $100B constellation replenishment market. Uses a 'hungry hippo' fairings design that opens at the top rather than traditional clamshell separation. First flight delayed to Q4 2026 after a Jan 2026 propellant tank test anomaly. | 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). |
