China is positioning large numbers of legacy J-6 fighter jets, potentially converted into J-6W unmanned aerial systems, at forward airbases facing Taiwan, signaling a potential shift toward mass saturation strike capability.
Satellite imagery analyzed by Japan shows these aircraft deployed alongside modern J-16 multirole fighters, as well as preparation for high-intensity air operations potentially designed to overwhelm Taiwan’s air defenses. This force structure could enhance China’s ability to rapidly generate large drone waves, directly impacting Taiwan’s air defense capacity, interceptor stockpiles, and overall battlefield resilience in a high-intensity conflict scenario.

On March 17, 2026, the Japanese National Institute for Defense Studies (NIDS) identified the increasing presence of 1960s-era J-6 fighters alongside modern J-16 multirole fighters at high-readiness bases facing Taiwan, based on satellite observation of coastal and inland airbases. This configuration appears in parallel with the sustained expansion of airbase infrastructure, including runway duplication, apron enlargement, and hardened shelter construction across Fujian and Guangdong. The central issue is the operational meaning of deploying such aging aircraft, but it becomes coherent when interpreted as part of a broader strategy integrating J-6W unmanned fighter jets.
However, the Japanese analysis focuses on spatial distribution rather than capability, examining how forward deployment, inland concentration, and infrastructure layout indicate a coordinated operational design. The observed structure combines forward staging areas with rear-area stockpiles, suggesting a scalable force that can be expanded rapidly before or during a conflict. The key variable is not the performance of individual fighter jets but the relationship between quantity, positioning, and intended use in a potential war against Taiwan. First, forward airbases along the Taiwan Strait show consistent patterns of modernization designed to support sustained sortie generation.
At Suixi airfield, the addition of a parallel runway, expanded taxiways, and larger apron space increases aircraft handling capacity beyond peacetime requirements, enabling simultaneous operations of multiple squadrons. Similar upgrades at Longtian airbase include hardened aircraft shelters, ammunition storage, and expanded parking areas capable of supporting dozens of fighters simultaneously. These features reduce turnaround time between sorties and improve survivability under attack. Furthermore, the scale of construction indicates a possible preparation for continuous operations over multiple days rather than short-duration exercises. Infrastructure density and redundancy also suggest that the Chinese bases are intended to sustain high attrition rates while maintaining operational output.
This configuration aligns with a possible operational model where drone-converted aircraft are expended in large numbers, mirroring the large-scale use of drones in the Ukraine war or by Iran in the Gulf. At these forward bases, satellite imagery shows J-6 aircraft positioned on the same apron as J-16 fighters, despite the lack of relevance of these Soviet-era jets. The modern J-16, equipped for air-to-ground and anti-ship missions, represents a modern strike asset with multi-role capability, while the J-6 is clearly not suited for contemporary air combat due to limited avionics, range, and survivability. Furthermore, standard Chinese air force practice avoids mixing such fighter types at forward bases because it complicates logistics, maintenance, and mission planning.
The remaining stock of Shenyang J-6s, a jet fighter derived from the Soviet MiG-19 and developed in China during the 1960s, is not marginal but consists of hundreds to potentially several thousand airframes.
The deliberate co-location, therefore, indicates that the J-6 is assigned a role that does not interfere with modern fighter operations. The most plausible interpretation is that these aircraft are not intended for conventional combat but for expendable missions. Their presence at forward bases suggests immediate availability for rapid launch rather than long-term storage or training use. A second spatial pattern is the concentration of large numbers of J-6 fighters at inland facilities such as Baofeng airfield in Henan province, located approximately 370 km southeast of Xi’an. This site contains hundreds of legacy aircraft arranged in configurations allowing rapid movement, with taxiways extending into mountain areas that include underground storage.
The absence of hardened shelters and combat support infrastructure indicates that the site is not configured for frontline operations. Instead, the presence of maintenance buildings and open apron space supports the interpretation of a storage and preparation facility. J-6s are positioned in a manner that allows immediate towing or flight preparation, indicating that they are maintained in a usable condition. This suggests that the inland site functions as a reserve pool from which aircraft can be drawn and redeployed to forward bases. The distribution of aircraft between inland and coastal bases forms a logistical structure in which a large reserve is held in depth, and a smaller number is positioned forward.
This arrangement allows rapid scaling of available assets by transferring aircraft from rear to front in the period preceding or during a conflict. If even 1,000 to 3,000 J-6 airframes remain usable, and a fraction is deployed immediately against Taiwan after conversion or preparation into J-6W drones, the number of such drones available for immediate operations can increase significantly within hours or days. Ferry flight distances from inland sites to coastal bases fall within the operational range of the J-6, enabling relocation without specialized transport. This structure supports surge operations, where initial waves are followed by additional deployments drawn from the reserve. The fleet is therefore designed for volume and persistence, matching the requirements for the employment of the J-6W drone.
The functional role of these aircraft is linked to long-standing Chinese capabilities in unmanned conversion and remote operation, developed over several decades. The J-6 airframe, originally capable of carrying up to 500 kg of payload and flying at supersonic speed, can be easily modified to remove pilot systems and integrate autopilot, remote control, or pre-programmed navigation. In such a configuration, designated as J-6W, the aircraft can operate as a one-way attack system or as a decoy designed to trigger defensive responses. A converted J-6 can carry an estimated 250 kg payload and travel at approximately 1,600 km/h, reaching targets within 30 to 40 minutes over a 700 km range.
For example, if a defense network can effectively engage 700 Iranian drones, and 1,000 Shaheds arrive within the same engagement window, then 300 drones will pass through unchallenged regardless of interception efficiency.
This combination of speed and payload increases the kinetic and explosive effect compared to smaller drones, while reducing interception time. The absence of a pilot allows the aircraft to be used in missions where loss is expected. In a Taiwan conflict scenario, these aircraft could be deployed in large numbers as an initial wave to force the activation of air defense systems and the expenditure of interceptors. If we imagine, based on known information about China and Taiwan, that 700 to 1,000 J-6W drones could be launched within a short timeframe, and that Taiwan’s defensive doctrine requires two interceptors per target, this would require 1,400 to 2,000 missiles to engage fully. With an estimated available pool of 1,200 to 1,800 interceptors across all layers, the saturation would occur once the maximum number of incoming targets a Taiwanese air defense system can effectively detect, track, and attempt to intercept is exceeded.
Assuming an 80 percent interception rate, a wave of 1,000 J-6Ws would still result in 200 penetrating attacks, delivering approximately 50,000 kg of payload. The time required to launch such a wave, at 100 to 250 aircraft per hour from multiple bases, would range from 4 to 8 hours. This creates a scenario in which Taiwan’s missile defensive capacity can be degraded within a single operational day, given that an air defense radar cannot distinguish with certainty between an unmanned jet such as the J-6W and a modern fighter jet such as the J-16. Recent conflicts, such as in Ukraine or around Iran, show that large-scale use of expendable aerial systems can impose unfavorable cost ratios on defenders, and it is common knowledge that China is studying them closely in order to improve its tactics.
In Ukraine, drones costing $10k to $50k have forced the use of interceptors costing up to $3M, creating sustained economic pressure and gradual depletion of missile stocks on both sides. The J-6-based model differs in that each unit has a higher speed and payload, increasing destructive potential while maintaining a lower cost than modern missiles. However, the larger radar signature of the aircraft makes detection easier, and reliance on runways limits launch flexibility compared to truck-launched drones. The effectiveness of the approach, therefore, depends on maintaining a high launch rate and coordinating multiple waves to sustain pressure, to oblige Taiwan to use its stockpile of anti-aircraft missiles.
From a strategic perspective, the approach targets the depletion of Taiwan’s air defense systems rather than attempting an immediate destruction of all assets. Therefore, the decisive factor becomes the ratio between incoming targets and available interceptors, combined with the cost of each engagement. If defensive forces rely primarily on high-cost interceptors, a rapid depletion could occur within 24 to 48 hours under sustained attack. If layered defense with lower-cost systems and electronic warfare systems is implemented, the saturation threshold increases to 1,200 to 1,500 incoming aircraft, extending the duration of effective defense to several days.
The tactic could therefore be effective for China in the initial phase of a conflict with Taiwan, particularly if it forces the use of expensive interceptors, but its long-term impact depends on the defender’s ability to adapt. Like in Ukraine and in the Gulf, the potential outcome of this scenario would be determined by the scale of J-6 conversions, inventory depth, and the ability for Taiwan to maintain is defensive effectiveness under sustained pressure.
