Astronstone develops AS-1, a partially reusable orbital rocket for commercial payload customers in the medium and heavy launch market.
Astronstone is a Chinese small-launch company building AS-1, a 4.2m-diameter stainless-steel methalox two-stage rocket, having completed a second-stage static-fire campaign in December 2025 and claiming China's first full-scale 100-ton-class chopstick capture-arm ground test. It targets a first-stage static fire in 2026 and a debut in Q1-27 at a $2,900/kg price, and is the most hardware-advanced of the Mechazilla-style Chinese entrants. It is pre-revenue (~$72M raised since 2023, including $29M in March 2026).
