Astra Rocket 4 Astra Launch System

Mission Profile

The Rocket 4 (Astra Rocket 4, Astra Launch System) is a planned two-stage American launch vehicle in the Astra family, a next-generation design intended to replace the unsuccessful Rocket 3 series with significantly improved performance and reliability. With a speculative first launch around 2030, the Rocket 4 represents Astra's pivot from its earlier ultralow-cost small launcher concept toward a more capable orbital vehicle, though the programme faces significant development uncertainty.
