China’s Jiutian SS-UAV, heralded as the world’s first “drone mothership,” has been pitched as a revolutionary leap in aerial warfare, promising to unleash swarms of drones from high altitudes to dominate battlefields. But before we get swept up in Beijing’s bold claims, let’s take a hard, critical look at this so-called game-changer. Is the Jiutian truly a paradigm shift in military technology, or is it an overhyped, oversized target waiting to be obliterated by modern air defenses? Spoiler alert: the latter seems far more likely.
The Jiutian SS-UAV, developed by China’s state-owned AVIC, boasts an 82-foot wingspan and a 16-tonne frame, designed to operate at altitudes up to 15,000 meters and deploy swarms of smaller drones for reconnaissance, strike, or electronic warfare missions. On paper, it sounds formidable—a mothership soaring above conventional threats, releasing a cloud of drones to overwhelm adversaries. But in the real world, this concept is riddled with vulnerabilities that make it more of a liability than a battlefield dominator.
China claims the Jiutian’s high-altitude operations place it beyond the reach of most air defense systems. However, as Tom Shugart, an adjunct senior fellow at the Center for a New American Security, pointed out in Newsweek, the Jiutian “doesn’t appear to be particularly stealthy” and is highly susceptible to destruction by enemy aircraft or air defenses before it can deploy its drone swarm. Let’s break this down.
With its massive size and likely significant radar cross-section (RCS), the Jiutian is anything but stealthy. Modern fighter jets like the U.S. F-35, India’s Rafale, or Taiwan’s upgraded F-16s, equipped with advanced AESA radars, can detect such a large, non-stealth platform from hundreds of kilometers away. Long-range air-to-air missiles, such as the Meteor carried by Rafale jets, boast ranges exceeding 200 kilometers and are designed to engage high-altitude targets with deadly precision. The Meteor’s active radar homing and ramjet propulsion make it a nightmare for lumbering giants like the Jiutian.
Beyond fighters, networked air defense systems pose an even greater threat. The U.S.’s Aegis-equipped destroyers, Japan’s advanced radar networks, or India’s D4 anti-drone system—successfully tested during Operation Sindoor against Pakistan’s drone swarms—demonstrate the capability to neutralize large-scale aerial threats. High-altitude surface-to-air missiles (SAMs) like the Patriot PAC-3 or the naval SM-6 are purpose-built to tackle threats at the Jiutian’s operating altitude. Even at 15,000 meters, this mothership is well within the engagement envelope of modern SAMs and interceptors.
China’s claims about the Jiutian’s endurance and ability to loiter for extended periods are equally suspect. A platform of this size, carrying a payload of smaller drones, would require significant fuel and power, limiting its operational range and loiter time. In contested environments like the Taiwan Strait or the South China Sea, where adversaries deploy layered defenses, the Jiutian would need to navigate a gauntlet of threats before even reaching its deployment zone. Electronic warfare (EW) systems, capable of jamming or spoofing the UAV’s communications and navigation, could further disrupt its mission, rendering its drone swarm ineffective.
The Jiutian’s core selling point—its ability to deploy swarms of smaller drones—sounds impressive but falls apart under scrutiny. Drone swarms, while innovative, are not invincible. India’s experience in countering Pakistan’s drone incursions during Operation Sindoor highlighted the effectiveness of integrated air defense systems combining sensors, jammers, and kinetic interceptors. A mothership like the Jiutian, which relies on its drones to achieve tactical objectives, becomes a single point of failure. If the mothership is neutralized before deploying its payload, the entire mission collapses.
Moreover, the smaller drones carried by the Jiutian are likely limited in range, payload, and autonomy, given the constraints of being launched from a mothership. These drones would face their own challenges surviving in contested airspace, where electronic countermeasures and anti-drone systems are increasingly sophisticated.
