Reusable Launch Vehicle Program Gets Underway to Catch Up with SpaceX

[Financial News] SpaceX drew global attention by demonstrating the reusable technology of its Falcon 9 launch vehicle. The technology is crucial because it can dramatically reduce the astronomical cost of space launches. Korea is taking on the challenge as well. Hanwha Aerospace has begun assembling a demonstrator, while Hyundai Rotem has unveiled a dedicated engine.
Hanwha Aerospace announced on the 30th that it had begun the final assembly of a reusable-technology demonstrator as part of efforts to secure reusable launch vehicle technology. Having proclaimed its goal of becoming the "Korean SpaceX," the company is moving closer to core space-launch technologies. Several space companies, including Hanwha Aerospace, the company responsible for the overall integration of Nuri (KSLV-II), are participating in the project led by the Korea Aerospace Research Institute (KARI).
The demonstrator is 12.2 meters tall and 1.5 meters in diameter, and will be equipped with a staged-combustion-cycle turbopump engine. The plan is to complete the technology demonstration by successfully conducting a vertical takeoff and landing test scheduled for 2028. During the flight test, the vehicle will take off vertically, climb to an altitude of 500 meters within 90 seconds, and then land vertically. The test is scheduled to be conducted twice.
Falcon 9's first-stage rocket has been reused dozens of times. If first-stage reusability is achieved under Hanwha Aerospace's leadership, next-generation launch vehicles in the 2030s could cost significantly less than existing ones. Beyond simply reducing costs, this is expected to provide a foundation for securing the price competitiveness needed to enter the future space transportation services market.
The key to reusable launch vehicles is technology that can control engine thrust, along with sufficient fuel efficiency. Hyundai Rotem's methane engine has therefore attracted attention. The engine was showcased at AEROTEC 2026, the second International Aerospace Technology Exhibition, which is being held in Changwon from today through the 2nd.
Hyundai Rotem is developing Korea's first methane engine. Methane produces less soot during combustion, resulting in higher fuel efficiency. That is why it is considered suitable as a propellant for reusable space launch vehicles. The Korea Research Institute for Defense Technology Planning and Advancement (KRIT) commissioned Hyundai Rotem last year to develop methane engine technology for reusable launch vehicles.
