Hanwha Group will invest 55 trillion won - roughly $38 billion - in aerospace and defense AI by 2040, building an independent space infrastructure that spans launch vehicles, satellite constellations, and a dedicated defense AI data center in South Korea's Yeongnam region. The plan, announced July 3 by Vice Chairman Kim Dong-kwan, puts hardware, software, and massive data systems on a single multi-decade roadmap.
A three-layer space architecture
Hanwha Systems is committing 20 trillion won to satellite technologies. The architecture starts with a very low Earth orbit (VLEO) synthetic aperture radar (SAR) constellation at 350 kilometers for ground and maritime surveillance. A space-based AI data center sits at 400 kilometers, and a low Earth orbit (LEO) communications network at 900 kilometers handles real-time data transmission. The company aims to launch 64 SAR satellites by 2031. The communications network will begin with 192 satellites, then add 60 more to replace older units and cover the Arctic. All satellites will ride on launch vehicles built by Hanwha Aerospace.
This stacked infrastructure demands continuous synchronization between edge computing on orbit and ground-based processing. The space AI data center and the data link layer form a closed loop where AI for IT & Development disciplines - distributed systems, low-latency networking, and model deployment across constrained environments - become central to delivering whole-of-orbit intelligence.
Launch and defense AI investments
Hanwha Aerospace will put 23 trillion won into launch vehicle development, including an integrated assembly facility and test infrastructure to shift from government-led launches to commercial service. Another 2 trillion won from the same unit targets defense AI: crewed and uncrewed aerial and ground weapon systems, plus integrated manned-unmanned teaming capabilities.
"The first step toward securing space sovereignty is developing our own launch vehicle," Kim said. "We will ensure that South Korea has the capability to reach space whenever it chooses."
A ground-based defense AI data center and Defense OS
Hanwha Aerospace, Hanwha Systems, and Hanwha Energy are jointly investing 10 trillion won in a defense AI data center in Changwon, South Gyeongsang Province. The facility starts at 45 megawatts this year and scales to 135 MW by 2032, with electricity supplied through Hanwha Energy's generation assets. The group is also spending an additional 2 trillion won on Defense OS, a battlefield AI model scheduled for completion in 2040. The model will turn platforms like the K9 self-propelled howitzer, unmanned surface vessels, underwater vehicles, and autonomous drones into intelligent weapon systems, while strengthening counter-unmanned aircraft systems.
Why this matters for IT and development
The full stack - from SAR satellites and orbital AI compute to a 135-MW ground data center and a custom defense AI model - represents a multi-decade buildout that will generate demand for skills in satellite ground station engineering, real-time data pipelines, model training on classified data, and hardened edge inference. It links software-defined payloads, orbital networking, and large-scale data center operations in a single program. Developers and infrastructure engineers who understand AI lifecycle management across distributed, power-constrained nodes will find a direct line from these investments to the tools and architectures they will be asked to build over the next 15 years.
