Gravity-2 (Yinli-2)

In Development

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. A first flight is targeted as early as 2026, with initial flights potentially using YF-102 engines while Yuanli-110 matures.
