Admiral Sarah Chen had spent thirty years tracking submarines in the Pacific, but she’d never seen anything quite like this. Standing on the deck of a destroyer off Taiwan, she watched through binoculars as an unfamiliar aircraft circled lazily overhead. No roar of jet engines, no visible pilot – just the quiet hum of electric motors and the unsettling knowledge that something was watching her submarine crews below.
“That’s not one of ours,” her operations officer muttered, lowering his own binoculars. The sleek, white drone had been orbiting their position for six hours straight, showing no signs of leaving. What bothered Chen most wasn’t the surveillance – it was the realization that the game had fundamentally changed.
This wasn’t science fiction. This was the Wing Loong X, and it represented China’s bold new strategy to hunt submarines from the sky using unmanned aircraft that can stay airborne longer than most people stay awake.
How China Plans to Change Submarine Warfare Forever
The Wing Loong X made its public debut at the Dubai Airshow in 2025, but its implications stretch far beyond the aviation industry. Built by China’s state-owned Aviation Industry Corporation (AVIC), this drone represents a fundamental shift in how nations might hunt submarines in the future.

For decades, anti-submarine warfare belonged to expensive, crewed aircraft like the U.S. Navy’s P-8A Poseidon. These planes cost hundreds of millions of dollars, require highly trained crews, and can only stay airborne for about 10 hours at a time. The Wing Loong X offers a completely different approach.
“We’re looking at a drone that can loiter over an area for 40+ hours without a single human onboard,” explains former Navy intelligence analyst Dr. James Morrison. “That changes the economics and risk calculation of submarine hunting entirely.”
The aircraft falls into what military experts call the MALE category – Medium Altitude, Long Endurance. But don’t let the technical jargon fool you. This designation means the Wing Loong X can fly high enough to avoid most surface-to-air missiles while staying in the air long enough to wait out even the most patient submarine commander.
Technical Specifications That Should Worry Pentagon Planners
AVIC hasn’t released every detail about the Wing Loong X, but what they have shared paints a picture of a capable submarine hunter. The drone can reach altitudes of approximately 10,000 meters and maintain flight for over 40 hours straight.
| Specification | Wing Loong X | U.S. P-8A Poseidon |
|---|---|---|
| Flight Duration | 40+ hours | ~10 hours |
| Operating Altitude | 10,000m | 12,500m |
| Crew Required | 0 (unmanned) | 9-11 personnel |
| Unit Cost | ~$15 million | ~$290 million |
| Risk to Personnel | Zero | High in contested areas |
The Wing Loong X carries an impressive sensor package designed specifically for maritime surveillance:
- Advanced synthetic aperture radar for surface detection
- Magnetic anomaly detector to spot submarine hulls
- Electro-optical sensors for visual identification
- Electronic warfare systems for signal interception
- Weapons bay capable of carrying anti-submarine torpedoes
“The sensor fusion capability is what makes this particularly concerning,” notes defense analyst Maria Rodriguez. “It’s not just about having the equipment – it’s about processing all that data automatically and making targeting decisions without human input.”
Chinese engineers claim the Wing Loong X can detect, track, and engage submarines completely autonomously. If true, this would represent the first fully automated submarine hunting system ever deployed.
What This Means for Global Naval Power
The strategic implications extend far beyond the South China Sea. U.S. and allied submarines have long enjoyed relative freedom of movement in international waters, knowing that finding and tracking them required enormous resources and highly skilled crews.
The Wing Loong X changes that equation dramatically. China could theoretically deploy dozens of these drones for the cost of a single traditional maritime patrol aircraft. More importantly, they don’t risk human lives, making them perfect for contested waters where nations might hesitate to send crewed aircraft.
“Submarine commanders have always relied on the vastness of the ocean as their primary defense,” explains retired submarine captain Robert Hayes. “When you can keep dozens of persistent sensors in the air 24/7, that vastness becomes much less protective.”
The export potential adds another layer of complexity. While the U.S. P-8A Poseidon is restricted to close allies, China has already indicated willingness to sell the Wing Loong X internationally. Nations with limited naval budgets could suddenly acquire submarine hunting capabilities that were previously reserved for major maritime powers.
Regional implications are particularly significant in areas like the Taiwan Strait, where submarine movements could determine the outcome of any future conflict. A network of Wing Loong X drones could provide China with unprecedented underwater domain awareness, potentially neutralizing one of Taiwan’s most important defensive assets – its submarine fleet.
The Technology Race That’s Just Beginning
The Wing Loong X represents more than just a new weapons system – it signals the beginning of an underwater surveillance arms race. The U.S. Navy is already responding with its own unmanned systems, including the MQ-4C Triton and various underwater drone programs.
But China may have gained a crucial first-mover advantage by focusing specifically on submarine hunting rather than general maritime patrol. The Wing Loong X was designed from the ground up for one mission: finding and destroying submarines as efficiently as possible.
“We’re seeing specialization in military drones that mirrors what happened in commercial aviation,” observes aerospace engineer Dr. Lisa Park. “Instead of one aircraft doing everything mediocre, you get focused platforms that excel at specific missions.”
The implications for submarine design are equally significant. Future submarines may need to operate under the assumption that they’re being continuously monitored from above, fundamentally changing tactics, routing, and operational planning.
Intelligence agencies are also paying close attention to the Wing Loong X’s autonomous capabilities. If China has truly achieved reliable automated submarine detection and targeting, it represents a significant leap in military artificial intelligence that could have applications far beyond anti-submarine warfare.
FAQs
How effective is the Wing Loong X compared to traditional submarine hunters?
While still unproven in combat, the Wing Loong X offers significant advantages in cost and endurance, potentially staying airborne four times longer than crewed aircraft at a fraction of the cost.
Can the Wing Loong X operate completely without human control?
China claims the drone can detect, track, and engage submarines autonomously, though independent verification of these capabilities remains limited.
Which countries might buy the Wing Loong X?
China has indicated willingness to export the system internationally, potentially making submarine hunting capabilities available to nations that previously couldn’t afford such technology.
How does this affect U.S. submarine operations?
U.S. submarines may need to adapt tactics and routes based on the assumption of continuous aerial surveillance in areas where Wing Loong X drones are deployed.
What countermeasures exist against the Wing Loong X?
Potential countermeasures include electronic warfare systems, surface-to-air missiles, and submarine-launched anti-aircraft weapons, though the drone’s altitude and endurance make it a challenging target.
When will the Wing Loong X enter active service?
China hasn’t announced a specific timeline, but the system’s public debut at Dubai Airshow 2025 suggests operational deployment could begin within the next few years.
