China’s Mysterious Stealth Jet Ignites a New Era in Air Power Competition
In the summer of 2025, blurry images of a mysterious, tailless stealth jet surfaced on Chinese social media, sending shockwaves through military circles worldwide. The aircraft’s sleek, angular design—with no vertical stabilizers, highly swept wings, and a pointed nose—immediately sparked speculation: Was this China’s third distinct sixth-generation crewed fighter, or a high-performance autonomous drone? The emergence of this jet, possibly a rival to the Shenyang J-50 or an advanced unmanned combat air vehicle, has intensified the already fierce US-China race for sixth-generation air dominance. Both nations now face a rapidly evolving technological and strategic landscape, where the balance of power in the skies is anything but certain.
What Makes a Fighter Jet ‘Sixth Generation’?
The term “sixth-generation fighter” is often used by militaries and analysts, but its definition remains fluid. Unlike previous generations, which were marked by clear technological leaps—such as the introduction of jet engines, supersonic flight, or stealth—sixth-generation fighters are defined by a combination of advanced features:
- Extreme stealth: New shapes, coatings, and systems to evade radar and infrared detection.
- Advanced sensors and networking: The ability to detect, track, and share information about enemy forces across vast distances.
- Artificial intelligence (AI) integration: AI assists with flying, threat detection, mission planning, and even autonomous decision-making.
- Manned-unmanned teaming: The ability to control or coordinate with “loyal wingman” drones that scout, jam, or attack targets.
- Long-range and high-speed performance: Engines and airframes designed for deep penetration into contested airspace.
- Flexible payloads: Internal weapon bays for hypersonic missiles, electronic warfare pods, and directed energy weapons.
These capabilities are not just about raw performance. They represent a shift toward operational dominance through integrated systems, survivability, and adaptability in highly contested environments. As Interesting Engineering explains, sixth-generation fighters are designed to act as flying command centers, gathering and sharing data instantly to enable faster, smarter decisions across air, space, cyber, land, and sea domains.
Why the Sixth Generation Matters
The development of sixth-generation fighters is not just a technological race—it’s a contest for strategic advantage. Air superiority has been a cornerstone of military success since World War II. The ability to control the skies enables maneuvering troops, resupplying forces, and conducting naval operations. As advanced air defenses proliferate and the threat environment evolves, both the US and China see sixth-generation fighters as essential for maintaining or gaining the upper hand in future conflicts.
China’s Rapid Advances: The J-36, J-50, and the Mystery Jet
China’s military aerospace industry has undergone a dramatic transformation in the past two decades. The unveiling of the J-20 fifth-generation stealth fighter in the 2010s marked a turning point, but recent developments suggest China is now pushing even further ahead. In late 2024 and early 2025, two new stealth jets—the J-36 and J-50—were spotted in test flights, followed by the appearance of the mysterious tailless jet in the summer.
The J-36: A Strategic Strike Platform
The J-36, reportedly developed by Chengdu Aircraft Corporation, is a large, tailless, tri-engine stealth fighter. Its design emphasizes:
- All-aspect stealth: The absence of vertical stabilizers and a blended wing-body reduce radar signature.
- High speed and range: Three engines provide supercruise capability (sustained supersonic flight without afterburners) and a combat radius of up to 1,500 nautical miles.
- Massive payload: A 7.6-meter internal weapons bay can carry long-range missiles, including hypersonic types.
- AI-enabled systems: Advanced avionics and networking for manned-unmanned teaming.
According to Asia Times and WION, the J-36 is designed for deep interdiction, strategic airspace denial, and acting as a command center for drone swarms. Chinese sources claim it can enforce airspace blockades up to 1,000 km away and counter advanced US platforms like the B-21 Raider bomber.
The J-50: Agile Air Superiority
The J-50, attributed to Shenyang Aircraft Corporation, is a smaller, twin-engine, tailless stealth jet. It features:
- Lambda-wing layout: For enhanced stealth and agility.
- AI-enabled flight control: For adaptive maneuvering and threat response.
- Carrier compatibility: Landing gear and design features suggest potential for naval operations.
With a top speed of Mach 2 and a combat radius of 2,200 kilometers, the J-50 is optimized for air superiority missions and could operate from China’s expanding fleet of aircraft carriers.
The Mystery Jet: Manned or Unmanned?
The latest stealth jet, seen in leaked images, has fueled intense debate among analysts. Its smaller, more streamlined airframe and lack of visible cockpit have led some to speculate it could be an advanced “loyal wingman” drone, designed to fly alongside crewed fighters and make tactical decisions using AI. Others argue it may be a third manned sixth-generation fighter, reflecting China’s strategy of developing multiple competing designs in parallel.
As aviation analyst Andreas Rupprecht told Swarajya, “The design bears similarities to the under-development J-50 and may reflect China’s push toward collaborative combat aircraft.”
Regardless of its exact role, the repeated sightings confirm that China is rapidly advancing both manned and unmanned next-generation air platforms, posing a significant challenge to the United States and its allies.
US Response: The Next Generation Air Dominance (NGAD) Program and the F-47
The United States has long enjoyed air superiority, thanks to its fifth-generation F-22 and F-35 fighters. However, the rapid pace of Chinese development has forced a reassessment. The US Air Force’s Next Generation Air Dominance (NGAD) program aims to deliver a sixth-generation fighter—now designated the F-47—alongside a family of unmanned Collaborative Combat Aircraft (CCA).
The F-47: Ambition Meets Reality
Announced by President Trump in March 2025, the F-47 is billed as the most advanced and lethal fighter ever built. Its features include:
- Stealth-optimized design: For survivability in contested environments.
- AI and advanced networking: To coordinate with drone wingmen and other assets.
- Long-range and payload: A combat radius exceeding 1,000 nautical miles and the ability to carry hypersonic and nuclear weapons.
- Carrier and land-based variants: To meet both Air Force and Navy requirements.
The NGAD program, however, faces significant challenges. With estimated costs of over $300 million per jet and a total program budget approaching $300 billion, affordability and production timelines are major concerns. The program was paused in 2024 for a reassessment, and only resumed after a new administration took office. The Air Force aims for a fleet of over 185 F-47s, supported by more than 1,000 drone wingmen, but questions remain about operational timelines and integration.
Meanwhile, the US Navy is pursuing its own next-generation carrier-based fighter, the F/A-XX, with concept art from Northrop Grumman showing a stealthy, single-pilot design optimized for carrier operations. The future of this program is also uncertain, as funding and priorities are debated within the Pentagon.
Strategic Implications and Risks
The introduction of the F-47 is seen as a direct response to China’s advancements. Defense Secretary Pete Hegseth claims it will reassure allies and deter enemies, but some analysts warn it could fuel an arms race and increase the risk of crisis escalation, especially among nuclear powers. As The Diplomat notes, “Enhancing military capabilities alone does not guarantee deterrence; credibility and resolve are also crucial.”
Comparing Capabilities: J-36 vs. F-47
Both the Chinese J-36 and the American F-47 represent the cutting edge of military aviation, but their approaches reflect different strategic priorities.
- Stealth and Survivability: Both jets use tailless designs and advanced materials to minimize radar and infrared signatures. The J-36’s triple engines and large airframe suggest a focus on range and payload, while the F-47 emphasizes multi-role flexibility and deep penetration.
- AI and Manned-Unmanned Teaming: Both programs prioritize AI integration and the ability to control drone wingmen. The US plans to field over 1,000 CCAs alongside the F-47, while China is developing collaborative combat aircraft and swarm tactics, though practical implementation lags behind.
- Weapons and Mission Profiles: The J-36 is designed to carry hypersonic missiles and enforce airspace blockades, potentially countering US bombers like the B-21. The F-47 is expected to carry a mix of air-to-air, air-to-ground, and electronic warfare payloads, with nuclear and hypersonic options.
- Carrier Integration: Both nations are developing carrier-capable variants, with China focusing on extending its naval reach and the US Navy pursuing the F/A-XX.
Experts caution that overreliance on stealth can be risky, as advances in detection technology may reduce its effectiveness. The true test will be the integration of these jets into broader systems of systems, including satellites, drones, and cyber capabilities.
Why Is China Moving So Fast?
One of the most striking aspects of China’s sixth-generation fighter programs is the speed of development. The J-20 moved from first flight to frontline service in just six years, compared to the 15-16 years it took for the US F-22 and F-35. This rapid pace is attributed to:
- Centralized planning and funding: China’s government can direct resources and prioritize military programs without the same budgetary constraints as the US.
- Digital design and manufacturing: Advanced simulation and assembly technologies accelerate prototyping and testing.
- Parallel development: Multiple competing designs are pursued simultaneously, increasing the chances of success.
US officials have expressed concern that China could field an operational sixth-generation fighter years before the US, potentially shifting the balance of power in the Indo-Pacific region. As The Aviation Geek Club notes, “China is not debating the relevance of sixth generation air dominance and is on track to field such fighters soon.”
