Chinese satellite firm aids Houthi attacks on U.S. warships

Reports have surfaced that a Chinese satellite company, Chang Guang Satellite Technology, is allegedly providing imagery to Yemen’s Houthi rebels, enabling them to target U.S. warships and commercial vessels in the Red Sea.

The accusations, raised by U.S. officials and reported by the Financial Times, have sparked concerns about the role of commercial space technology in modern conflicts. The Red Sea, a vital artery for global trade, has been a hotspot for Houthi attacks since late 2023, disrupting shipping routes and prompting U.S. and allied military responses.

This development raises questions about China’s involvement, the proliferation of satellite technology, and the future of maritime security in a region critical to the global economy.

The allegations center on Chang Guang Satellite Technology, a Chinese firm with reported ties to the People’s Liberation Army. According to U.S. officials, the company has supplied the Houthis with high-resolution satellite imagery, which the Iran-backed group uses to pinpoint targets in the Red Sea.

State Department spokesperson Tammy Bruce confirmed the reports, stating, “We can confirm the reporting that Chang Guang Satellite Technology Company Limited is directly supporting Iran-backed Houthi terrorist attacks on U.S. interests.” She described the firm’s actions as “unacceptable,” noting that the U.S. had raised concerns with Beijing multiple times, to no avail.

The Chinese Embassy in Washington, however, claimed to be unaware of the issue, and Chang Guang has not issued a public response. These claims, while serious, remain unverified by independent sources, and the lack of concrete evidence underscores the need for cautious analysis.

Social media platforms like X have amplified the discussion, with analysts sharing infographics that map Houthi attacks since December 2023, though these posts offer no definitive proof of Chinese involvement.

To understand the significance of these allegations, it’s essential to examine the technology at the heart of the issue. Chang Guang Satellite Technology operates the Jilin-1 satellite constellation, a network of commercial satellites designed for high-resolution Earth observation.

The Jilin-1 satellites, first launched in 2015, are capable of capturing images with a resolution of up to 0.5 meters, allowing for detailed monitoring of objects on the ground or at sea. These satellites orbit at altitudes between 500 and 650 kilometers, providing frequent revisits—some as often as every few hours.

The constellation includes optical, hyperspectral, and video satellites, which can capture dynamic footage of moving targets, such as ships. This capability makes Jilin-1 a powerful tool for real-time surveillance, with applications ranging from urban planning to military reconnaissance.

By comparison, Western commercial providers like Maxar Technologies offer similar resolutions, with their WorldView-3 satellite achieving 0.31-meter resolution, while Planet Labs’ SkySat constellation provides 0.5-meter imagery. China’s rapid expansion of its commercial space sector, however, has outpaced many competitors, with Chang Guang operating over 100 satellites by 2025, a scale that rivals global leaders.

The Houthis, a Zaydi Shia militant group controlling parts of Yemen, have relied on relatively low-tech weapons—drones, anti-ship missiles, and small boats—for their Red Sea campaign. Their arsenal includes the Iranian-supplied Qasef-1 and Qasef-2 drones, with ranges of up to 200 kilometers, and ground-launched missiles capable of striking targets 800 kilometers away.

Integrating high-resolution satellite imagery into their operations would mark a significant leap in capability. Such data could enable precise targeting of moving vessels, compensating for the group’s lack of advanced radar or reconnaissance systems.

The process likely involves intermediaries, possibly Iranian operatives, who analyze the imagery and relay coordinates to Houthi forces. This mirrors other conflicts, such as Ukraine, where commercial satellite providers like Maxar and Starlink have supplied imagery and connectivity to support military operations.

The difference lies in the actors involved: while Western firms operate under strict regulatory oversight, the allegations against Chang Guang suggest a looser framework in China, raising questions about Beijing’s control over its private sector.

The Red Sea’s strategic importance cannot be overstated. The waterway handles approximately 12% of global trade, including 30% of container shipping and significant volumes of oil and liquefied natural gas. The Bab-el-Mandeb Strait, a narrow chokepoint between Yemen and Djibouti, is particularly vulnerable to disruption.

Since November 2023, the Houthis have launched over 100 attacks on commercial ships and U.S. warships, sinking two vessels, seizing one, and killing at least four seafarers, according to a U.S. Defense Intelligence Agency report. The group initially claimed to target Israeli-linked ships in solidarity with Palestinians during the Gaza conflict, but their strikes have been indiscriminate, affecting vessels from dozens of nations.

Major shipping companies, including Maersk and MSC, have rerouted vessels around the Cape of Good Hope, adding 7 to 14 days to transit times and increasing costs by an estimated $200 billion in 2024, per The Economist. The Suez Canal, which relies on Red Sea traffic, saw a 75% drop in throughput last year, hammering Egypt’s economy.

The U.S. response has been multifaceted. Operation Prosperity Guardian, a U.S.-led naval coalition, patrols the Red Sea to protect shipping, while American and British forces have conducted airstrikes on Houthi targets in Yemen.

Since January 2024, the U.S. has targeted Houthi command centers, weapons facilities, and leadership, with recent strikes killing at least 53 people, according to Yemen’s Houthi-run health ministry. President Donald Trump, in a March 2025 statement on Truth Social, warned the Houthis that “Hell will rain down upon you like nothing you have ever seen before” if attacks persist, signaling an escalation in U.S. policy.

The alleged involvement of Chang Guang complicates this strategy. If confirmed, it could prompt targeted sanctions, as seen in 2023 when the U.S. penalized the firm for reportedly supplying imagery to Russia’s Wagner Group. However, broader measures against China risk straining diplomatic ties, especially given Beijing’s role as a mediator in Middle East conflicts.

Geopolitically, the allegations fit into a complex web of interests. China’s Belt and Road Initiative relies heavily on secure trade routes, including the Red Sea, where Chinese firms have invested billions in Egyptian infrastructure along the Suez Canal.

Beijing’s silence on the Houthi attacks—despite threats to its own commercial interests—reflects a cautious approach. The Diplomat noted in January 2024 that China’s People’s Liberation Army Navy abstained from joining Operation Prosperity Guardian, and its warships ignored distress calls from attacked vessels. This restraint aligns with China’s policy of non-interference, but it also exposes the limits of its global security influence.

The Houthis’ reported agreement to spare Chinese-flagged ships, possibly in exchange for support, suggests a pragmatic arrangement. A March 2024 incident, where Houthi missiles struck a Chinese-owned tanker by mistake, highlights the risks of such deals.

Iran, the Houthis’ primary backer, adds another layer. China’s purchase of 90% of Iran’s oil exports helps Tehran evade sanctions, creating an indirect link to the Houthis. Yet Beijing also maintains ties with Saudi Arabia and the U.S., balancing competing interests in a volatile region.

Historically, the use of commercial satellite imagery in conflicts is not new. During the Cold War, reconnaissance satellites were the domain of superpowers, with the U.S. Corona program and Soviet Zenit satellites providing grainy images for strategic planning.

The commercialization of space in the 1990s changed this dynamic. Companies like Space Imaging [later GeoEye] and DigitalGlobe [now Maxar] began offering high-resolution imagery to governments and private clients. The 2003 Iraq War saw widespread use of commercial satellite data by U.S. forces, while the 2011 Libyan conflict demonstrated its value for real-time targeting.

Today, the accessibility of such technology has democratized intelligence, enabling non-state actors like the Houthis to acquire capabilities once reserved for nation-states. This shift has outpaced international regulations, which struggle to address the dual-use nature of commercial satellites. The 1967 Outer Space Treaty, for instance, governs state activities but offers little clarity on private firms.

The credibility of the allegations against Chang Guang remains a critical issue. The Financial Times cited anonymous U.S. officials, and the State Department’s confirmation provides some weight, but no public evidence—such as intercepted communications or imagery samples—has been released.

Posts on X, including infographics tracking Houthi attacks, offer valuable context but lack specificity about Chinese involvement. The Washington Institute’s maritime incident tracker, for example, documents over 100 attacks since November 2023 but does not mention satellite imagery sources.

Past accusations against Chang Guang, such as its 2023 sanctions for aiding the Wagner Group, suggest a pattern, but they also highlight the challenge of distinguishing corporate actions from state policy. China’s military-civil fusion strategy blurs these lines, as firms like Chang Guang often serve both commercial and government clients.

Independent verification, perhaps through signals intelligence or open-source analysis, would be necessary to substantiate the claims. Until then, the allegations risk being overshadowed by geopolitical rhetoric.

The implications for Red Sea security are profound. If the Houthis are indeed using satellite imagery, their ability to conduct precise, long-range strikes could escalate, challenging the U.S. Navy’s dominance in the region.

The Department of Defense reports that the Houthis have targeted U.S. warships over 170 times without success, thanks to advanced countermeasures like the Aegis Combat System. However, commercial vessels, often equipped with minimal defenses, remain vulnerable.

The U.S. could counter this threat through cyberattacks on Houthi communication networks or diplomatic pressure on China to rein in its firms. Long-term, the proliferation of commercial satellite technology demands new strategies. Proposals for international oversight, such as a UN framework for regulating dual-use imagery, have gained traction but face resistance from spacefaring nations.

The Council on Foreign Relations has warned that unchecked disruptions in the Red Sea could ripple through global supply chains, raising consumer prices just as inflation stabilizes.

Looking ahead, this situation underscores broader trends in warfare and geopolitics. The democratization of space technology has lowered the barrier for non-state actors to wage sophisticated campaigns, blurring the line between conventional and hybrid conflicts.

China’s role, whether intentional or incidental, highlights the challenges of managing a multipolar world where economic and security interests collide. The U.S. must navigate this carefully, balancing military resolve with diplomatic engagement to avoid alienating key partners.

The Red Sea crisis also exposes gaps in global governance, as commercial technologies outpace regulatory frameworks. Could other groups—pirates, militias, or rogue states—exploit similar tools to destabilize critical regions? The question lingers, demanding a reckoning with the unintended consequences of a commercialized cosmos.
