Gravity-2 (Yinli-2)

Overview

Two-stage, partially reusable kerosene-liquid oxygen heavy-lift rocket with a vertically landing first stage powered by nine in-house Yuanli-110 engines — Orienspace's higher-than-Falcon-9-class vehicle.

The Yuanli-110 engine completed its first test firing in September 2025 and a nozzle-less restart test in November 2025. An Orienspace official has said the first flight is now targeted for the end of 2026 (a slip from earlier targets), with initial flights potentially using YF-102 engines while Yuanli-110 matures.
