A landmark achievement in space launch technology was accomplished on July 10th when the first stage of the Long March 10B rocket successfully completed a controlled recovery on a maritime platform after liftoff from the Hainan Commercial Space Launch Site.

This event marks the first successful controlled recovery of a launch vehicle's first stage in China and represents the world's inaugural implementation of a net-based recovery system for a launch vehicle.

This breakthrough signals China's formal entry into a new era of low-cost, high-frequency reusable space access, accelerating the large-scale deployment of satellite constellations and unlocking a definitive growth inflection point for the entire commercial space industry chain.

Long March 10B, developed by the First Academy of the China Aerospace Science and Technology Corporation, is a large reusable liquid-propellant launch vehicle designed for the commercial market. With a total length exceeding 70 meters and a liftoff mass of approximately 760 tons, its recovered configuration offers a low Earth orbit payload capacity of over 16 tons, placing it within the same tier as leading international reusable rockets.

Its globally pioneering maritime net-based recovery system, utilizing attitude control, engine retro-thrust, and capture by a flexible net, significantly reduces landing precision requirements and enhances fault tolerance, offering strong advantages for commercial viability.

With the completion of this technological demonstration, the stage is set for mass production and high-frequency launch campaigns, directly benefiting core suppliers across the industrial chain.

Key Investment Opportunities Across the Value Chain

Overall System Integrator: The Primary Beneficiary

Aerospace Engineering (SSE: 603698), with a 46% stake held by the First Academy, stands as its sole listed platform. As the core listed entity of the Long March 10B's chief developer, the company is deeply integrated with the First Academy's rocket development and commercial launch operations, directly capturing the industrial benefits from the Long March and Jielong series commercial rockets.

With the maturation of reusable rocket technology and the sustained growth of commercial launch orders, the company, as the core listed platform of the primary research institute, is positioned to fully capture the core benefits from the expansion of the commercial space industry.

Rocket Core Components: Critical Power and Avionics

The rocket's propulsion and flight control systems represent the technological heart and highest-value segments of a reusable vehicle. Associated component manufacturers are poised for sustained earnings growth as rocket production scales up.

Aero-Engine Corporation (SSE: 600343) supplies hot-end and fluid components for the YF-100K liquid oxygen/kerosene engine, the core powerplant for the Long March 10B's first stage. Each rocket is configured with seven YF-100K engines, making them a crucial part of the reusable rocket's propulsion system. As rocket production ramps up and reuse cycles increase, demand for engine production and maintenance will rise concurrently, positioning the company for significant earnings leverage.

Sirui New Materials (SSE: 688102) supplies the material for the inner wall of the YF-100K engine's thrust chamber. The thrust chamber is a core component operating under extreme temperatures and pressures, requiring materials with exceptional high-temperature resistance and erosion resistance, representing a key technological barrier. By breaking through these high-end aerospace material barriers and securing a position in the core supply chain, the company is set to realize sustained earnings as rocket production enters a mass manufacturing phase.

Aerospace Electronics (SSE: 600879) provides core electronic systems for the rocket, including inertial navigation and flight control systems, which are essential for precise flight and controlled recovery. Reusable rockets impose far greater demands on flight control and guidance precision compared to traditional expendable rockets. As a leading supplier in the aerospace electronics field, the company's technological prowess and market share position it to benefit deeply from the technological upgrades and increased launch frequency driven by reusable rockets.

Shaanxi Huada (SZSE: 301517) supplies electrical connectors and assemblies for the rocket, which are fundamental components for signal and power transmission across the vehicle's entire electrical system, meeting the connection needs of all subsystems. The mass production of commercial rockets will directly drive demand expansion for electrical connectors. By securing a place in the core supply chain with its reliable product performance, the company has opened up significant growth potential within the aerospace sector.

Maritime Recovery System: Executors of a Pioneering Technology

The net-based recovery system is the most distinctive core technology of the Long March 10B and a critical enabler for reusable rocket operations. Companies involved in its overall design and component supply possess significant technical barriers and promising long-term growth prospects.

CITIC Heavy Industries (SSE: 601608) served as the prime contractor for the net recovery system, leading the development and implementation of the world's first integrated "well-shaped" net capture, buffering, and locking system. The maritime net recovery solution features high technical barriers and strong reusability, positioning it to become the mainstream recovery route for China's reusable rockets. As launch frequency increases, demand for the construction and upgrading of recovery systems will grow steadily, granting the company, as the prime technical integrator, a formidable first-mover advantage and competitive moat.

Hailanxin (SZSE: 300065) provided command, measurement, and control ship support for the maritime recovery mission, undertaking critical functions for telemetry, communication, and command dispatch throughout the recovery process. This support is vital for the successful completion of offshore recovery tasks. As maritime recoveries become routine and rocket launch density continues to rise, demand for offshore measurement, control, and support services will grow in tandem, ensuring sustained benefits for the company as a core support provider.

Launch Site Support: Essential for High-Frequency Operations

Jiufeng Energy (SZSE: 301090) is the exclusive supplier of specialty gases for the Hainan Commercial Space Launch Site, providing critical gases such as liquid methane, liquid oxygen, liquid nitrogen, and helium for launch missions. The Long March 10B utilizes liquid oxygen/kerosene and liquid oxygen/methane propulsion, creating stable and inelastic demand for these specialty gases. With the anticipated increase in mission volume at commercial spaceports, the company, as the sole support provider, is set to secure a stable stream of incremental earnings.

The successful maritime recovery of the Long March 10B represents a pivotal turning point for China's commercial space sector, transitioning from technological validation to scaled application. Reusable technology promises to dramatically reduce launch costs, catalyzing the accelerated development of trillion-dollar markets like satellite internet and the broader space economy.

From the overall integrator and core components to the recovery system and launch support, the core listed companies across each segment of the A-share industrial chain are positioned to realize their long-term growth value alongside the sustained expansion of commercial space, solidifying their status as a central theme within the technology growth investment landscape.
