World’s Longest Ranged Carrier-Based Ship Hunter

 China’s supercarrier Fujian with new J-15T configuration,  Heavy anti-ship strike capability 

New imagery confirms the PLA Navy's J-15T can launch heavy anti-ship missile payloads from the CATOBAR-equipped Fujian, marking a major leap in China's carrier strike capability and maritime deterrence.  Imagery released in early July 2026 provides the first public confirmation that the PLA Navy has integrated the J-15T into a complete anti-shipping configuration aboard the Fujian supercarrier, enabling a single fighter to deliver concentrated missile effects which were previously constrained by ski-jump limitations on earlier platforms. This demonstration pairs substantial anti-ship ordnance mass with the extended operational flexibility created by electromagnetic catapults, fundamentally altering how carrier strike packages can be composed and sustained during high-intensity maritime operations across the Indo-Pacific. The configuration signals that the PLA Navy has overcome previous payload restrictions, allowing the J-15T to function as a primary maritime strike asset capable of influencing adversary surface force movements at tactically significant distances without requiring multiple aircraft for equivalent effects.                         

The Chinese People’s Liberation Army Navy has for the first time revealed the anti-shipping configuration of its new long ranged carrier-based fighter, the J-15T, with the aircraft seen carrying four YJ-83K anti-ship cruise missiles. The image highlights the significant anti-surface firepower that China’s latest carrier air wing is able to bring to bear, with the fighters having been procured both to modernise the air wings of the Navy’s two older aircraft carriers Liaoning and Shandong, and its new supercarrier the Fujian. Not only does the J-15T have a far higher weapons carrying capacity and longer range than Western carrier-based fighters, but its operations from the Fujian also allow for higher takeoff weights due to its electromagnetic catapult launch system - a system only the US carrier USS Gerald Ford otherwise has. The YJ-83K is a well-established subsonic anti-ship cruise missile weighing approximately 700 kg's, and with a 230 km range. A J-15T carrying four such weapons therefore departs with roughly 2.8 tonnes of anti-ship ordnance before accounting for air-to-air missiles or external fuel tanks. This highlights demonstrates the substantial payload made possible by both the aircraft’s strengthened structure compared to prior J-15 variants, and by the integration of electromagnetic catapult launch systems. The new launch system can thus significant extend both the aircraft’s range and its combat effectiveness. 

Defence analysts assess that the heavy loadout represents a deliberate evolution in force posture, strengthening China’s ability to impose costs on potential intervention forces by expanding the reach and density of carrier-based anti-surface fires in contested sea lanes. The event carries clear strategic signalling value because it publicly displays a mature strike package at a time when regional maritime disputes continue to shape operational planning and alliance calculations throughout the western Pacific. Geopolitical assessments indicate the demonstration complicates adversary calculations for surface operations in the South China Sea and Taiwan Strait by showing credible ability to deliver massed missile salvos from a mobile, survivable platform backed by advanced escorts. The integration of such heavy anti-shipping loads with the Fujian’s launch system accelerates the PLA Navy’s transition toward more offensive carrier employment concepts which prioritize rapid effects generation over previous defensive or limited-strike roles. Force posture analysts note that the configuration strengthens layered anti-access capabilities when combined with long-range systems already deployed on Type 055 destroyers, creating overlapping threat envelopes which raises the operational risk for any opposing naval formation. Such developments shift the broader battlespace dynamics by enabling Chinese carrier air wings to contribute more effectively to area denial strategies that aim to deter or delay external power projection into regional chokepoints and island chains.

Ultimately the Fujian air wing’s evolution with these strike packages positions the PLA Navy to exert greater calibrated pressure on maritime domains that remain central to both economic  security and  military balance in the Indo-Pacific. It is notable that the YJ-83K is not the most capable anti-ship missile type which has been integrated onto the J-15T, with  unofficial photographs taken by Chinese aviation enthusiasts earlier having captured one of the fighters carrying two YJ-15 missiles during what appeared to be flight testing. The new missile provides a substantial leap in capability over the YJ-83K, including a near hypersonic speed and a range of 500 km's. Its distinctive aerodynamic configuration includes three sets of control surfaces extending from front to rear: forward strakes integrated around the air intake, rectangular mid-body fins, and rear control surfaces mounted near the engine nozzle. The J-15T now carries four individual 700 kg YJ-83K missiles that together deliver approximately 2.8 tonnes of dedicated anti-ship ordnance in one sortie, a payload mass that substantially exceeds the one or two missiles typically observed on earlier STOBAR J-15 variants operating from ski-jump carriers. This increased ordnance delivery stems directly from airframe reinforcements, upgraded WS-10 engines, and the removal of ski-jump weight penalties, allowing the fighter to depart with full strike load plus defensive armament and reserve fuel.

The configuration modernizes strike planning across the entire PLA Navy carrier fleet because the same J-15T airframe can now operate effectively from both the catapult-equipped Fujian and the ski-jump decks of the Liaoning and Shandong without major payload compromises. Military-technical evaluations show that concentrating 2.8 tonnes of anti-ship ordnance on a single platform reduces the number of aircraft required to achieve decisive effects against surface targets, thereby improving overall sortie efficiency and lowering the logistics burden on the carrier deck. Strategic consequence analysis reveals that this heavy loadout enables carrier strike groups to allocate fewer fighters to anti-surface missions while preserving greater numbers for air superiority or defensive tasks during complex multi-axis operations. The ability to carry such ordnance mass while retaining mixed weapon flexibility allows the J-15T to adapt rapidly between pure strike profiles and multi-role missions depending on the evolving threat environment. Analysts conclude that the 2.8 tonne package alters force packaging decisions by giving commanders the option to generate concentrated missile salvos from fewer launch platforms, which in turn complicates adversary air defence saturation calculations.

This capability directly supports broader PLA Navy objectives of developing integrated strike options which combine carrier aviation with surface and subsurface assets to create synchronized effects against high-value naval targets. Geopolitical impact assessments highlight how the demonstrated loadout strengthens deterrence messaging by showing credible capacity to threaten distant surface formations without relying exclusively on land-based missile systems. The heavier strike configuration therefore functions as both a tactical multiplier and a strategic signalling tool that raises the perceived cost of any naval intervention in waters adjacent to Chinese territory. The Nimitz class’ far older design places greater limitations on fighters’ takeoff weights, however the Gerald Ford has continued to suffer from wide ranging performance issues with its subsystems. These issues have affected its weapons elevators, electromagnetic catapults, human waste management and sensors, with a Project on Government Oversight report accordingly having referred to the program as an example of “how not to build a ship.”

Military-technical evaluations note that conventional propulsion on the Fujian imposes inherent range and on-station endurance constraints which nuclear-powered US carriers do not face during prolonged operations. The PLA Navy offsets this limitation through tighter integration between the Fujian air wing and long-range anti-ship systems deployed on accompanying Type 055 destroyer escorts, creating a more distributed but still coordinated strike network. The newer KJ-600 AEW&C platform supplies enhanced situational awareness and targeting support which multiplies the combat effectiveness of J-15T strike packages operating at extended ranges.  Analysts assess that US operational maturity, global logistics infrastructure and extensive combat experience still provide response flexibility and sustained presence advantages which current Chinese carrier numbers have not yet matched. Force posture comparisons reveal both sides optimizing different core strengths within distinct logistical, endurance and technological frameworks shaped by their respective strategic priorities and industrial bases. Geopolitical observers conclude that ongoing Chinese advancements in heavy strike configuration and electromagnetic launch capability narrow specific operational gaps while US nuclear endurance and mature integration continue to preserve broader global power projection options across multiple theatres.

The demonstrated J-15T loadout on the Fujian therefore represents a focused and rapid evolution in regional maritime strike dynamics which raises the complexity of any potential conflict without fundamentally overturning existing naval balances. Although the Fujian has a number of disadvantages, its air wing is in many respects much more capable than those of U.S. supercarriers, with the J-15 and J-35 both benefitting from significantly longer ranges and higher weapons carrying capacities than the F-18E/F and F-35C, carry much larger radars, and have superior flight performances with much higher thrust-weight ratios. Its KJ-600 AEW&C systems relied on to boost situational awareness and provide long range targeting support are also much newer and thought to integrate more advanced electronics and more powerful radars. The J-15T is in many respects now the world’s premier maritime strike fighter, with its very long range and high missile payload in particular far surpassing those of all other carrier based fighter types, complementing the advanced capabilities of its new generations of weaponry. The potency of the Fujian’s air wing itself complements the significant advantages which Chinese destroyer escorts have established in their long range anti-ship capabilities over their US counterparts.

The J-15 and J-35 fighters provide longer combat radius, heavier external payload capacity and larger radar apertures than the F/A-18E/F or F-35C, enabling them to generate effects over greater distances while carrying more substantial ordnance loads. Superior thrust-to-weight ratios resulting from twin-engine designs and recent domestic engine advancements allow these platforms to maintain high performance even when fully loaded with anti-ship missiles and defensive armament. These performance characteristics enable the J-15T to carry the demonstrated four-missile strike package while retaining sufficient fuel margins for extended missions and return to the carrier without immediate refuelling requirements. Military-technical comparisons confirm that the larger radar on the J-15 family offers greater detection volume against both surface and air targets, improving situational awareness and target acquisition timelines during complex strike operations. The J-35’s stealth characteristics complement the J-15T’s heavy strike role by providing options for penetrating reconnaissance and selective engagement which can shape the battlespace before massed missile attacks are launched.

Strategic assessments indicate that these combined attributes allow Chinese carrier air wings to generate meaningful effects at ranges where Western platforms often face difficult payload, endurance or survivability trade-offs. The performance differential directly influences force design choices by enabling more flexible tasking of carrier-based fighters across air superiority, strike and reconnaissance missions within a single air wing. Analysts conclude that the larger radar and payload capacity enhance the effectiveness of coordinated strikes when supported by the KJ-600 AEW&C aircraft, which supplies extended detection and targeting data to the entire strike package. Force posture advantages emerge clearly when these fighters operate from a catapult-equipped deck that removes the weight penalties previously imposed by ski-jump operations on earlier Chinese carriers. Geopolitical impact stems from the demonstrated ability to project credible, heavy anti-ship power from mobile platforms across wider ocean areas, thereby altering the perceived balance of maritime strike capabilities in the Indo-Pacific.

The YJ-83K anti-ship cruise missile provides a 230 km engagement envelope when launched from the J-15T, allowing strikes against surface targets well beyond the immediate sensor horizon of the launching aircraft or its accompanying surface escorts. This range creates operational space for the carrier to remain outside the most effective engagement zones of many adversary air defence systems while still delivering precise effects against high-value ships. The J-15T has also been observed carrying the larger near-hypersonic YJ-15 missile, which offers an estimated 500 km reach and significantly higher terminal speeds which reduces adversary reaction windows and complicate last-ditch defensive engagements. Military-technical analysis suggests the combination of subsonic volume fire from multiple YJ-83K missiles and high-speed penetration profiles from the YJ-15 creates diversified threat vectors which stress integrated air and missile defence architectures. Strategic consequence evaluations show these missile systems enable the J-15T to contribute meaningfully to anti-access corridors at distances that previously required land-based or submarine-launched weapons for equivalent coverage. The missile evolution supports tighter integration between carrier aviation and the long-range anti-ship systems already fielded on Type 055 destroyer escorts, creating synchronized multi-domain strike options. Force posture impacts include expanded operational flexibility for coordinated air-surface operations without requiring forward deployment of additional land-based strike assets which could be more easily targeted.

Geopolitical implications centre on how these weapon ranges reshape risk calculations for any naval force attempting to operate within the expanded engagement envelopes now available to Chinese carrier strike groups. The layered missile capability therefore strengthens the overall lethality and flexibility of the Fujian air wing while raising the operational threshold required for successful intervention in regional maritime disputes. Fujian’s three electromagnetic catapults enable significantly higher takeoff weights than the steam systems installed on Nimitz-class carriers, even though the Chinese vessel displaces only around 85,000 tons at full load. The medium-voltage direct current power system delivers smoother and more controllable acceleration profiles which reduces structural stress on heavily loaded aircraft during launch, thereby supporting sustained high-payload operations without accelerated airframe fatigue. This technical advantage allows the J-15T to depart with the full four-missile anti-ship load plus additional fuel or defensive weapons, extending both combat radius and time on station compared with previous ski-jump limitations.  Military planners recognize that the ability to launch heavier packages directly increases the density of effects that can be generated per sortie, which in turn reduces the total number of launches required to achieve operational objectives.

Strategic assessments indicate that electromagnetic launch technology accelerates sortie generation rates under combat conditions by permitting aircraft to carry more ordnance and fuel on the first evolution rather than requiring multiple lighter launches. The catapult system therefore functions as a force multiplier for the entire Fujian air wing by expanding the envelope of feasible strike profiles without demanding proportional increases in deck cycle time or support assets. Force posture implications include the capacity to maintain persistent anti-ship coverage over wider areas while lowering reliance on vulnerable aerial refuelling assets that could be targeted in contested airspace. The technology narrows specific capability gaps in heavy strike reach while preserving the operational flexibility needed for rapid reconfiguration of air wing tasking during dynamic maritime campaigns. Geopolitical observers conclude that this launch system advantage contributes to a more credible power projection posture which can influence adversary freedom of movement across critical sea lines of communication. Military observers conclude that the J-15T’s demonstrated capacity to carry four YJ-83K missiles modernizes the strike options available across all three Chinese carriers, creating a more uniform and lethal air wing capability that reduces previous disparities between ski-jump and catapult-equipped platforms. This advancement directly enhances the logistics footprint of carrier strike groups by allowing heavier initial loads that extend combat endurance and reduce the frequency of rearming cycles during sustained operations.

From carbon sinks to carbon sources

 Tropical forests and their ability to store carbon during El Niño

Tropical forests draw down and store large quantities of CO₂ from the atmosphere. The Amazon rainforest in South America, for example, stores approximately 123 billion tons of carbon, more than is stored in any other terrestrial ecosystem in the world. But these forests are facing a critical challenge. New research shows that tropical forests are taking up less CO2 from the atmosphere, reducing their ability to act as ‘carbon sinks’ and instead becoming sources of carbon. What does this mean for the future of humanity? The Amazon could turn into a source of carbon instead of one of the biggest absorbers of the gas as soon as the next decade, as a result of the damage caused by loggers and farming interests and the impacts of the climate crisis. Research from 2023, found that tropical forests in South America are vulnerable to climate extremes. During an El Niño event, the warm phase of a natural fluctuation in Earth's climate system, South American tropical forests may fail to act as a carbon sink. Finding becomes even more alarming when we consider the increasing frequency and intensity of El Niño events. There have been twice as many "very strong" El Niños in the past 60 years as there were in the 60 years before that. And the US National Oceanic and Atmospheric Administration has recently confirmed that such an El Niño is currently underway.

Changes in tropical forest carbon sink strength during El Niño Southern Oscillation (ENSO) events can indicate future behavior under climate change. Previous studies revealed ˜6 Mg C ha-1 yr-1 lower net ecosystem production (NEP) during ENSO year 1998 compared with non-ENSO year 2000 in a Costa Rican tropical rainforest. Researchers explored environmental drivers of this change and examined the contributions of ecosystem respiration (RE) and gross primary production (GPP) to this carbon sink. For 1998-2000, RE using chamber-based respiration measurements, and estimated GPP in two ways: using (1) the canopy process model MAESTRA, and (2) combined eddy covariance and chamber respiration data. MAESTRA-estimated GPP did not statistically differ from GPP estimated using approach 2, but was ˜ 28% greater than published GPP estimates for the same site and years using eddy covariance data only. A 7% increase in RE (primarily increased soil respiration) and a 10% reduction in GPP contributed equally to the difference in NEP between ENSO year 1998 and non-ENSO year 2000. A warming and drying climate for tropical forests may yield a weakened carbon sink from both decreased GPP and increased RE. Understanding physiological acclimation will be critical for the large carbon stores in these ecosystems.

Tropical forests absorb CO₂ through the process of photosynthesis and convert it into biomass. However, the balance between photosynthesis and respiration is delicate and depends on two factors: temperature and water availability. In hotter and drier conditions, plants close the pores of their leaves to avoid water loss. But closing them effectively cuts off a plant's fuel supply because it is through these pores that they absorb CO₂. This starves plants of the carbon needed for photosynthesis and growth. During El Niño years, which are characterized by high-temperature anomalies, prolonged climate stress leads to reduced forest growth and increased tree mortality. The effects of this are felt for decades as carbon is released back into the atmosphere when the dead trees decompose. Intact tropical forests sequestered almost 50% of the global terrestrial carbon uptake over the 1990s and early 2000s, removing about 15% of CO2 emissions. These carbon sinks are becoming saturated in both Amazonian and African rainforests, with different patterns of change. These rainforests are now taking up a third less carbon than they did in the 1990s, owing to the impacts of higher temperatures (trees have only partially acclimated to recently rising temperatures), droughts and deforestation. This downward trend is likely to continue, as forests come under increasing threat from the climate crisis and exploitation. The typical tropical forest may become a carbon source by the 2060s. 

Tropical rainforests act as net carbon sinks when the amount of carbon gained through the establishment of new trees and tree growth is larger than the amount lost through tree mortality. In these circumstances, the quantity of carbon stored in the biomass increases over time. Findings revealed that during the 2015–2016 El Niño, when temperatures on land were at least a degree higher on average than usual conditions, some of South America's tropical forests effectively stopped absorbing carbon. This raises concerns about the possible impact of the current El Niño on the Amazon and global climate. In the research, team measured over half a million trees across six South American countries over a period of more than 30 years, using tape measures to track their growth. These trees belonged to more than 4,000 different species. This data was used to calculate precise estimates of the amount of carbon stored as a forest's aboveground biomass. The vulnerability of these forests to El Niño conditions was closely linked to their baseline climate. By assuming that rainforests are all hot, wet and biodiverse ecosystems, seasonal drought is a reality for many tropical forests. Conditions in regions at the edge of the Amazon rainforest, for example, tend to be particularly hot and dry. Findings revealed that drier forests at the edge of the Amazon, where trees regularly endure periods of limited water availability, were especially susceptible to extreme El Niño conditions. On average, a 0.5°C increase in temperature caused these forests to lose 0.5% of their aboveground carbon. 

Larger trees suffered the most. While tree mortality rates increased from 1.8% to 3%/year during the El Niño in South American tropical forests as a whole, mortality rates effectively doubled for medium (classified as over 20 cm) and large trees. The fact that larger trees with less dense wood died at much higher rates than small trees and those with high wood density points strongly to hydraulic failure, when intense atmospheric moisture demand snaps the tension in the tree's internal water column rather than slow carbon starvation. These results suggest that adaptation to seasonal drought may not be sufficient to protect tropical forests from extreme events. Climate extremes are possibly already pushing forests at the edges of the Amazon beyond their capacity to adapt, causing catastrophic carbon losses. The researchers of the study monitored tree establishment, growth and mortality in 244 undisturbed forest plots in Africa across 11 countries between 1968 and 2015. This data was then compared with similar measurements from 321 plots in the Amazonian region. The results showed that carbon uptake in the Amazonian region started to decline around 1990, whereas signs of a potential slowdown in Africa appeared in 2010. The uptake of carbon from the atmosphere by tropical forests peaked in the 1990s when about 46 billion tonnes were removed from the atmosphere, equivalent to about 17% of carbon emissions from human activities. By the last decade, that amount had sunk to about 25 billion tonnes, or 6% of global emissions, similar to a decade of fossil fuel emissions from the UK, Germany, France and Canada put together. 

According to the report, by 2030, the carbon sink in Africa will be 14% lower than in 2010-2015, while the Amazonian carbon sink will reach zero by 2035 (meaning that there will be no more net carbon uptake from the atmosphere). The researchers say that the reason for this difference between Amazonian and African tropical forests is because of increasing mean annual temperatures and droughts since 2000 that have reduced tree growth, offsetting the increase in carbon uptake. These reductions are smaller in Africa than in Amazonia. Scientists have warned that 2026 may again be the warmest year on record. Heightening the alarm further is the severity of the current El Niño. Never before has an El Niño begun when oceans are already so warm and air temperatures so high. On top of this is the fact that, over the past three decades, the edges of the Amazon have experienced some of the highest temperatures and most rapid warming the tropics have ever seen. The structural integrity of a forest is compromised when a major climate anomaly occurs before it has recovered from recent, multi-year stress. These compounding factors mean that we risk witnessing tree and carbon losses on scales not yet seen.

Further, the higher carbon gains persisted for longer in Africa than in Amazonia because the warming rate was slower, there were fewer droughts and air temperatures were generally lower (because African forests are located at higher elevations). Generally, trees in Amazonia grow faster and have shorter residence times than those in African forests. According to the report, the carbon sink strength of the world’s two most extensive tropical forests ‘have now saturated’. Reaching emissions reduction targets counts largely on the continuation of a large tropical carbon sink, which are disappearing at a rapid rate and could soon turn into carbon sources by the end of the decade. The protection of these tropical forests as well as faster greenhouse gas emissions will be needed to prevent catastrophic climate changes.  Tropical forests are invaluable assets in the fight against climate change. But South American tropical forests, a once-reliable carbon sink, are vulnerable to intensifying heat and drought. There is a risk that these essential ecological allies will stop acting as a carbon sink as extreme climate conditions become the norm. Preserving tropical forests is thus essential. Their ability to continue acting as carbon sinks hinges on efforts to protect them and a collective commitment to limit global temperature rise. The Amazon's future depends on this, and so does ours. UN climate talks will most likely see many countries coming forward with plans to reach net zero emissions by mid-century. This will be crucial in the fight against anthropogenic global warming.
