China’s first purpose-built maritime space launch command and telemetry vessel, the Dongfang Hengyuan, has recently been successfully launched. This high-end marine asset, custom-designed for the full lifecycle of maritime space launch missions, has lifted China’s maritime support capabilities for commercial aerospace to a new height. Powering this cutting-edge vessel is its core "heart" — four main propulsion units independently developed by CSSC Henan Diesel Engine Industry Co., Ltd. (CSSC HDE), a leading enterprise based in Luoyang.
Designed and constructed under the auspices of Harbin Engineering University, the Dongfang Hengyuan is a true innovation pioneered in China. To meet the stringent operational demands of maritime space launches, the vessel is equipped with an all-electric drive system paired with dual conventional shaft propellers, as well as DP-2 dynamic positioning technology. This configuration enables high-precision stationary positioning in complex marine conditions, delivering a stable operational platform for space launch command and telemetry work — an indispensable technical safeguard for successful maritime launch missions.
The vessel’s primary power comes from four main propulsion units engineered by CSSC HDE. Maritime space launch missions place extreme demands on power systems, leaving no room for compromise when it comes to reliability and stability. To address these requirements, CSSC HDE’s R&D team carried out a full-scale optimization and upgrade of the propulsion units, ensuring seamless integration with the vessel’s overall design. The finished products not only passed all rigorous bench tests and were delivered to the shipyard without a hitch, but the company also deployed professional technical personnel to provide end-to-end technical support for equipment installation, solidly fulfilling its role as the vessel’s reliable power provider.
The successful launch of the Dongfang Hengyuan is not only a landmark success for CSSC HDE’s collaboration with China’s high-end marine equipment manufacturing sector, but also lays a robust power foundation for China’s upcoming maritime space launches and marine scientific expeditions. Under the plan, the vessel will be officially delivered in June 2026. Once in service, it will operate in tandem with the Dongfang Space Port launch vessel, marking a significant boost to the support capacity and mission efficiency of China’s maritime launch system. What’s more, the vessel features an efficient dual-purpose design: during non-space mission periods, it will partner with the Dongfang Hengjing marine test platform to conduct marine scientific research operations, maximizing the operational value of this high-end marine equipment.
As a longstanding pillar enterprise in China’s marine power equipment industry, CSSC HDE has once again demonstrated the prowess of "Luoyang Smart Manufacturing" with its independently developed propulsion systems. A senior representative of CSSC HDE noted that the company will continue to focus on the R&D and manufacturing of high-end marine power equipment, deepen collaborative ties with the aerospace, marine engineering and related sectors, and contribute its share to the development of China’s maritime power strategy and aerospace industry with more reliable products and high-quality services.
From dedicated maritime launch vessels to supporting command and telemetry ships, China’s layout for commercial aerospace at sea is growing increasingly comprehensive. The launch of the Dongfang Hengyuan has not only filled the gap in China’s purpose-built maritime space launch command and telemetry equipment, but also strengthened the full-chain support system for the country’s maritime space launch missions. With the vessel’s official commissioning on the horizon, China’s maritime space launch capabilities are poised for more efficient and diversified development, propelling the nation to forge ahead at a faster pace in the global commercial aerospace race.
