| Summary | 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. | Primary launch vehicle for Cygnus ISS cargo missions from 2013–2023. Its Ukrainian-built Zenit-derived first stage and Russian RD-181 engines became untenable after the 2022 invasion of Ukraine. Northrop switched NG-20 onward to Falcon 9 while Antares 330 (with Firefly Miranda engines) is in development. | China's workhorse medium-lift rocket, used exclusively for Tianzhou automated cargo missions to the Tiangong space station. Designed to replace the Long March 2F for high-cadence LEO/cargo missions. Uses the same YF-100 engines as Long March 5's boosters. |
