(DEFENCE SECURITY ASIA) — China could launch its fourth aircraft carrier, the Type 004, in late 2027, bringing Beijing closer to a fleet that could sustain fighter and surveillance operations farther into the Western Pacific if the ship’s suspected nuclear propulsion is confirmed.

An October 27 satellite imagery assessment by the Center for Strategic and International Studies (CSIS) puts construction at Dalian roughly where Fujian stood in May 2021, making late 2027 or early 2028 a plausible launch window if assembly continues at a comparable pace.

Brian Hart of the CSIS China Power Project said he “would not be surprised” by that timetable if construction maintains its pace, a qualification that matters because joining prefabricated blocks reveals little about progress on the machinery inside them.

Fujian entered service on November 5, 2025, after more than three years of fitting out and trials, a benchmark that puts the strategic weight on when Type 004 can deploy with a trained air wing and a fully integrated strike group.

Two roughly 15-by-15-metre compartments visible in satellite imagery are consistent with shielded reactor spaces, which makes nuclear propulsion plausible and raises the prospect that the People’s Liberation Army Navy could sustain higher speeds between replenishments during distant deployments.

The unfinished hull measured about 322 metres by 46 metres in early October, giving designers more room than Fujian’s hull offered at a comparable stage and potentially easing competition for hangar space, aviation fuel, weapons storage and shipboard machinery.

A larger hull paired with electromagnetic catapults could support a broader mix of aircraft, allowing a single Chinese carrier to maintain airborne surveillance and fighter cover while reserving deck capacity for strike aircraft during an extended operation at sea.

The most immediate regional consequence would emerge east of Taiwan, where a carrier air wing could put fighters and airborne radar on a second axis and make US and allied planners account for threats approaching from the Philippine Sea.

That prospect depends on a battle group able to screen the carrier, sustain the air wing and share targeting information with shore-based forces, since a longer-ranged flight deck can add commitments for escorts and supply ships across the same theatre.

A float-out during the PLA’s 2027 centenary year would give Beijing a visible symbol of shipbuilding progress, signalling that it can build a carrier on the scale of the largest US warships while its navy develops the capacity to operate one.

If Type 004 follows even a broadly similar path, its contribution to deployed Chinese combat power would emerge in the early 2030s, when carrier availability, trained aircrews and the ability to replenish underway will matter more than the launch date.

For Washington and its allies, the planning question is how often China could keep a carrier group on station beyond the First Island Chain, where sustained aviation would complicate the movement of reinforcements between the Western Pacific and East Asia.

Dalian’s Construction Pace Makes a 2027 Launch Plausible

Prefabricated sections began appearing in a Dalian dry dock in early 2025, and by May 2026 their assembly had produced a recognisable carrier hull, showing how parallel fabrication can compress the time that large components occupy a scarce dock.

By August, the hull had reached roughly 320 metres in length and 46 metres across its widest visible section, meaning the ship was already approaching the scale of a US supercarrier before the bow and wider flight deck took shape.

Imagery from September 4 showed work on the bow, with the completed ship projected at 336 to 339 metres, a range comparable to the Gerald R Ford class and useful for judging scale while aviation capacity remains uncertain.

Scaffolding visible around October 1 indicated preparations for the forward deck, side sponsons and starboard island, milestones that will help clarify the usable flight deck area and how the ship might divide space among launch, recovery and aircraft handling.

Several large flight deck sections were reportedly added within about five days around the turn of October, a pace consistent with modules arriving ready for assembly and a reminder that visible advances depend on work completed elsewhere in the yard.

Fujian’s first modules entered dry dock around July 2020 and its superstructure was fitted about a year later, making the transition from hull assembly to installation of major structures the most useful visible comparison for judging progress at Dalian.

Fujian launched on June 17, 2022, roughly 13 months after reaching the stage used to benchmark Type 004, so the analogy supports a late 2027 or early 2028 window while leaving room for differences in the larger ship’s construction sequence.

The Type 004’s greater beam at the same stage is clearer evidence than its projected full-load displacement of 110,000 to 120,000 tons, which depends on assumptions about the completed ship, installed equipment and the loads it will carry at sea.

A launch by the PLA’s August 1 centenary would offer a precise date for political signalling, but the imagery-based estimate points later in the year and Beijing has released no schedule against which to judge whether work is ahead or behind.

The next construction milestones will sharpen estimates of when Dalian can float the hull, whereas acceptance of its propulsion, electrical and aviation systems will determine when the navy can begin turning that industrial achievement into a deployable carrier group.

Nuclear Propulsion Would Change the Carrier Group’s Logistics

The compartments visible in May imagery have multiple layers consistent with shielding and differ from Fujian’s layout at a comparable stage, while Beijing has yet to confirm the propulsion choice or disclose how many reactors the ship might carry.

If nuclear propulsion is confirmed, the carrier could spend longer at high speed without drawing down conventional propulsion fuel, giving commanders more freedom to reposition between operating areas or remain at distance while keeping more tanker capacity available for escorts.

Reactor-generated power could support repeated electromagnetic catapult launches alongside radar and other high-demand systems, with the actual operational gain dependent on how well the ship distributes power and maintains those systems through sustained periods of flying and surveillance.

A nuclear plant would reduce one of the largest fuel demands in the group, but conventionally powered escorts and the carrier’s aircraft would still draw on replenishment ships for fuel while aviation munitions, food and spare parts would require resupply.

Greater aviation fuel and weapons stowage could lengthen the interval between replenishments, especially on surveillance and fighter patrols, while intensive strike operations would burn through those stocks faster and make the timing of supply rendezvous a more important operational constraint.

Reducing the carrier’s demand for ship fuel could free replenishment capacity for other vessels, but the availability of suitable support ships and the security of their routes would still shape how far China could sustain a task group from home.

A nuclear fleet would also require specialist crews, maintenance infrastructure and reactor support, concentrating part of the logistics burden ashore and making the availability of trained personnel and appropriate facilities as consequential as the speed of hull production.

Integrating a first carrier reactor plant could extend the post-launch schedule by years, because propulsion and electrical systems would have to demonstrate reliability at sea before crews could establish repeatable operating routines during demanding flight and manoeuvring cycles.

The Gerald R Ford class offers a benchmark for the scale of ship China appears to be building, while the useful comparison at sea will be whether Type 004 can sustain operations with comparable demands on escorts, replenishment and maintenance.

The strategic gain from nuclear propulsion would therefore be greater freedom to position the carrier and stay there, with the length and intensity of an operation still governed by how reliably the wider fleet can keep aircraft armed, fuelled and serviceable.

J-35 Fighters and KJ-600 Radar Aircraft Would Define Combat Power

Type 004 is expected to use catapult-assisted take-off and arrested recovery, extending Fujian’s shift from ski-jump launches toward a system that can send heavier aircraft aloft and give the fleet more options for combining fighters with fixed-wing airborne surveillance.

Four electromagnetic catapults are a plausible configuration against Fujian’s three, but their number and placement remain unconfirmed, and any increase in launch capacity would depend on aircraft handling and recovery cycles as much as the availability of launch tracks.

Estimates of 75 to 100 aircraft exceed the roughly 50 to 60 projected for Fujian, although a ship carrying helicopters, surveillance aircraft and unmanned systems would have fewer spaces available for fighters than the headline total might suggest.

The J-15T multirole fighter would give the air wing flexibility to divide aircraft between fleet defence and maritime strike, while catapult launch could improve the trade-off between fuel and weapons loads compared with the constraints imposed by a ski-jump deck.

The J-35 stealth fighter could make opposing airborne surveillance and fighter screening more demanding, with its contribution depending on how many aircraft are available and whether the carrier can maintain them through successive sorties away from shore facilities.

The KJ-600 airborne early warning and control aircraft could extend radar coverage beyond the ship’s line of sight, giving escorts and fighters earlier warning and improving the group’s ability to coordinate interceptions when operating beyond reliable support from land-based sensors.

A mixed air wing could assign Z-20 variants and unmanned systems to support missions while preserving fighter capacity, but each aircraft type would compete for deck space, maintenance personnel and recovery windows during periods of intensive flight operations.

Additional aircraft elevators and an aft-positioned island could ease movements between the hangar and the deck, allowing crews to prepare aircraft for launch while keeping recovery areas clear if the final arrangement supports that division of work.

The final sensor, defensive and electronic warfare fit remains uncertain, making the air wing’s ability to share tracks with escorts and other forces more consequential to fleet defence than assumptions about individual systems inferred from the hull’s size.

A larger air wing would create its strongest advantage if the navy can keep airborne radar and fighter patrols operating while preparing a strike, a test of crew proficiency, maintenance and deck coordination under pressure from opposing forces.

Taiwan and the First Island Chain Shape the Deployment Case

A carrier group east of Taiwan could bring radar coverage and fighters to approaches less directly covered by China’s shore-based air forces, giving Beijing more options to support a blockade or challenge allied aircraft and ships entering from the Pacific.

That position would become more consequential if the carrier could exchange surveillance and targeting data with China’s land-based missile and air forces, creating overlapping threats that force allied commanders to divide reconnaissance, air defence and escort resources across several axes.

The same operating area would expose the carrier to submarine patrols and long-range strike, requiring escort ships and aircraft to protect a large, hard-to-replace asset while still supporting the offensive or surveillance missions that justify its deployment there.

In the Philippine Sea, a carrier-based early warning aircraft could widen the group’s ability to detect approaching aircraft and coordinate fighters, but coverage would depend on keeping those patrols airborne and maintaining communications in a contested electromagnetic environment.

Farther into the Western Pacific, operations toward the Second Island Chain, which includes Guam, would increase the area across which US planners must track Chinese aviation while extending the distances over which Beijing would have to sustain escorts and replenishment ships.

In the South China Sea, a carrier could sustain air cover and surveillance during operations linked to Beijing’s maritime claims, with the political signal amplified by its visibility and the military value shaped by access to nearby land-based aviation.

Near the Strait of Malacca, an extended carrier presence would put Chinese naval aviation closer to a major shipping chokepoint, but operating there would also place sustained demands on escort coverage and make support ship movements more consequential.

An Indian Ocean deployment would be a more demanding test of blue-water operations, because distance from home waters would make the availability of aviation spares, maintenance support and replenishment as decisive as the endurance offered by the carrier’s propulsion.

Allied submarines, long-range strike and unmanned surveillance could impose costs by forcing the group to devote aircraft and escorts to protection, while cyber and electronic disruption could degrade the network that turns airborne detection into a coordinated defensive response.

The net effect on allied access would vary with geography and readiness, since a carrier that can sustain patrols east of Taiwan poses a different problem from one whose escorts and supply ships must spend more time in transit.

China’s Carrier Ambition Faces a Fleet Readiness Test

The progression from the ski-jump Liaoning and Shandong to the conventionally powered Fujian and the likely nuclear Type 004 gives China’s navy successive opportunities to build proficiency, with each step increasing demand for personnel trained in distinct launch and propulsion systems.

The Pentagon’s 2025 assessment projects that China aims to field nine carriers by 2035, a US estimate of Beijing’s ambitions that would require sustained construction at Dalian and Jiangnan as well as enough personnel and escorts to operate the ships.

Adding six carriers by 2035 implies an average pace of roughly one every 18 months, which would likely require parallel construction and enough industrial capacity to fit out and trial several ships while supporting carriers already in service.

Hull output would be only one measure of fleet growth, because each commissioned carrier would compete for naval aviators, deck crews, air wing maintenance specialists and escort availability, potentially widening the gap between total inventory and deployable strength.

The US Navy’s 11 nuclear carriers provide a global inventory advantage, while China’s ability to concentrate ships in nearby waters could allow it to match or exceed the number immediately available to Washington in a specific Western Pacific crisis.

That local balance would turn on deployment cycles, maintenance and warning time, since ships tied to commitments elsewhere or undergoing refits cannot influence a contingency on the same timetable as carrier groups already within reach of the theatre.

China’s ability to maintain one carrier group on station while another trains or undergoes maintenance would mark a more consequential change than a single distant deployment, because repeated availability would force other navies to account for Chinese carrier aviation routinely.

Commissioning would establish that the ship had entered service, while integrated exercises and repeated deployments would show whether commanders can combine its air wing, escorts and shore-based forces under the operational pressures likely to define a Western Pacific contingency.

A 2027 launch would give Beijing a platform for strategic signalling years before the ship could credibly sustain combat operations, making subsequent evidence of flight trials, qualified aircrews and distant replenishment essential to assessing changes in the regional balance.

The shift that matters for the Indo-Pacific will come when China can keep a carrier air wing operating beyond the First Island Chain through maintenance demands, allied pressure and repeated replenishment, turning Dalian’s shipbuilding tempo into a sustained military presence.
