| Summary | A liquid-biomethane orbital smallsat launcher from Interstellar Technologies, Japan's most established private rocket startup by suborbital flight heritage, though not yet flown to orbit. | Firefly Aerospace's two-stage small-lift rocket powered by four Reaver engines at sea level and one Lightning engine in vacuum. Also provides launch services for NASA's CLPS programme (Blue Ghost lander launched on Falcon 9). FLTA007 'Stairway to Seven' succeeded Mar 11, 2026. | 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. |
