| Summary | Relativity Space's Falcon-9-class successor to Terran 1, partially 3D-printed, with 13 Aeon R methalox engines on a reusable first stage; second stage and fairing expendable. | The world's most frequently flown orbital rocket. Block 5 first stages have landed over 280 times and reflown up to 23 times. Backbone of Starlink and commercial crewed launches. | Australia's first domestically developed orbital launch vehicle attempt, using a hybrid-propellant first and second stage; the maiden flight failed 14 seconds after liftoff in July 2025. |
