Recent Activity
Gravity-1 maiden flight from sea platform January 2024 (largest solid rocket to date); ongoing CZ-11 commercial cadence; Haiyang sea-port infrastructure expansion through 2025.
Investor Brief
Removes overflight politics entirely — Chinese sea launches avoid debris-fall complaints from Russia, Mongolia, and Central Asia that plague inland Chinese pads. Operationally critical for solid-fuel commercial launchers (LM-11, Gravity-1, Smart Dragon).

Strategic Position
36.7000° N, 121.2000° E
Azimuth: Variable — vessel positioning enables 30°–180° azimuth without overflight constraints
Mobile — vessel typically deploys to 35°N–5°N depending on mission; can reach near-equatorial positioning for GTO trades or higher latitudes for SSO
Future Milestones
- 2026
Larger sea-based platform commissioned for liquid-fuel commercial rockets
- 2027
Gravity-2 (liquid, larger payload) maiden flight from sea platform
About
The Haiyang Sea Launch Platform is China's innovative sea-based launch capability, operating from mobile launch vessels in the Yellow Sea off Shandong province. First demonstrated in 2019 with a Long March 11 rocket, sea launches allow flexible positioning to optimize orbital insertion and avoid overflying populated land areas during ascent.
Key Features
China's first sea-based orbital launch capability
Mobile launch platform can be positioned for optimal trajectories
Avoids overflying populated areas — rocket stages fall into open ocean
Supports Long March 11 solid-fuel rocket and commercial variants
Based out of Haiyang port in Shandong province
