Space is no longer a peaceful domain of exploration or a distant frontier. It has become the "fiercest and coldest battlefield," directly tied to national survival. The testimony of Kari Bingen, an advisor at the Center for Strategic and International Studies (CSIS), before the U.S. House Foreign Affairs Committee in late April delivers a painful warning. Her stern diagnosis is that America's space hegemony is being rapidly eroded, and that this will soon translate into a security crisis for the entire liberal democratic camp.
The point we must pay particular attention to is the "weaponization and universalization of commercial satellite technology." The recent case of Iran's attack on U.S. military bases in the Middle East starkly illustrates this. It is shocking that Iran, which does not possess advanced military reconnaissance satellites, secured precision strike coordinates by utilizing commercial satellite intelligence from China. Surveillance and reconnaissance capabilities, once the exclusive preserve of great powers, are now being placed in the hands of hostile forces under the civilian guise of "commercial satellites." The era of the "democratization of space threats" has arrived, in which civilian technology returns as a boomerang threatening security.
The Ukraine war has also proven that space is both the "primary strike target" and the "game changer" of modern warfare. Just before the war began, Russia launched a massive cyberattack on Viasat, a commercial satellite network, in an attempt to paralyze Ukraine's command structure. However, Ukraine maintained battlefield transparency through SpaceX's "Starlink" commercial satellite service, laying the foundation for its counterattack. This demonstrates that commercial space assets can serve as both the "Achilles' heel" and the "last bastion" of national security.
This pattern of global space warfare presents us with a clear and urgent task. Beyond simply importing foreign technology or relying on overseas services, we must cultivate a "self-sustaining domestic commercial space ecosystem."
First, we must secure "data sovereignty" for national security.
Intelligence is the rice of modern warfare and the foundation of blood alliances. Just as Iran borrowed intelligence from China, if we rely solely on foreign commercial satellites in a contingency, a security vacuum may emerge at decisive moments depending on the international situation and the interests of the providing country. Only when small satellite constellations built with our own technology densely monitor our skies and we directly control that data can an "independent surveillance network" and "intelligence self-reliance" — beholden to no one — be completed.
Second, space resilience stems from the speed and flexibility of domestic commercial space. The old-space, government-led approach, which requires massive budgets and more than a decade of time, is insufficient to respond to space threats that change by the day. "Space resilience" — producing and launching hundreds of small satellites cheaply and quickly so that the entire system remains operational even if one is destroyed — is impossible without the innovative capabilities of the private sector. Through bold deregulation and full-scale support, we must create an environment in which domestic private companies can shorten development cycles. The stronger domestic commercial space capabilities become, the more resilient and robust our military's security assets will be.
Third, fostering commercial space is a strategic fusion of national future growth engines and security.
The space industry is a concentrated aggregate of cutting-edge technologies including AI, ultra-high-speed communications, semiconductors and advanced materials. Growing the domestic commercial space market is not merely about forging a shield to protect the country from enemy attacks. It is also about sharpening the spear to seize leadership in the Fourth Industrial Revolution, and it is an economic security strategy to expand the territory of "K-space defense" globally as an exporting nation.
Space belongs to those who seize it first, and can only be enjoyed by those who defend it. We must squarely face the reality that commercial satellites have become the eyes of the enemy, staring us down. Fostering the domestic commercial space industry is no longer an investment for the distant future, but a matter of survival for today.
The government, industry and military must come together as one team to consolidate Korea's unique space capabilities. Time in space flows faster than on Earth. Now is precisely the moment when a decisive resolution is needed, with the fate of South Korea's space security and domestic space industry at stake.
