China has formally branded its carrier-based J-35 stealth fighter as “Blue Shark,” signaling that the aircraft is moving from development into early operational integration within its naval air arm. The move underscores Beijing’s push to field a stealth-capable carrier fighter that can extend air superiority and strike reach from its expanding fleet of aircraft carriers.
The J-35 combines low observable design, internal weapons carriage, and carrier compatibility to support contested airspace operations and long-range interception missions. Its development alongside a land-based variant reflects a broader strategy to accelerate fifth-generation capability, improve survivability at sea, and strengthen China’s ability to project power across maritime theaters.

On April 23, 2026, lyman2003 revealed that Shenyang Aircraft Corporation confirmed that the Chinese Navy’s carrier-based variant of its J-35 stealth fighter carries the official nickname “Blue Shark” (蓝鲨), formalizing a designation that had already appeared at the Zhuhai Airshow in November 2024 on a Shenyang design institute patch. References to this name had circulated since at least 2022, indicating that the designation was internally established well before public confirmation. Fighters linked to the naval variant of the J-35 have been photographed with PLA Navy insignia and fuselage marking, but without the numerical side codes typical of operational squadrons.
This absence of tactical numbering is consistent with aircraft not yet assigned to combat units. By mid-2025, multiple airframes were visible on assembly lines and in flight testing configurations, indicating a transition from prototype to early production. The confirmation of the nickname coincides with the broader public exposure phase observed between 2024 and 2026, where visual identification, flight demonstrations, and carrier trials were progressively disclosed by Chinese authorities. The naming structure follows an established pattern within China’s PLA Naval Aviation, where carrier aircraft are assigned shark-related identifiers.
The J-15 operates under the name Flying Shark, while the electronic warfare J-15D is designated Electric Shark, placing the J-35 within a consistent naming lineage tied to carrier aviation units. The land-based variant J-35A is designated Yunlong (Cloud Dragon), indicating a separation in identity between naval and air force configurations despite shared design origins. The first visible reference to “Blue Shark” occurred through a unit patch at Zhuhai 2024 rather than through formal announcement channels, indicating a phased disclosure approach. The persistence of the name in informal circulation since 2022 suggests that the designation was stable throughout late development stages.
The alignment of naming conventions across carrier aircraft supports continuity in fleet aviation identity and corresponds with the navalized J-35’s transition into early operational integration. The development of the J-35 begins with the FC-31 prototype 31001, which conducted its first flight on October 31, 2012, establishing the baseline configuration for the program. A second prototype introduced on December 23, 2016, incorporated structural redesigns, a single-piece canopy, and WS-13E engines producing about 87 kN of thrust, replacing earlier RD-93 engines. The navalized J-35 prototype conducted its first flight on October 29, 2021, featuring a catapult launch bar, folding wings, and a reinforced landing gear configuration.
A land-based variant, later designated J-35A, conducted its first flight on September 26, 2023, with a single-wheel nose landing gear and reduced wing area. The J-35A was publicly displayed and flown at Zhuhai in November 2024, marking its first official demonstration. On September 3, 2025, both variants were included in the PLA inventory during the V-Day parade in Beijing. On September 22, 2025, the PLA Navy confirmed successful catapult launch and recovery trials aboard the Type 003 aircraft carrier Fujian. By mid-2025, aircraft with serial numbers linked to test units were observed, indicating entry into a low-rate production phase. The J-35 is a medium-weight stealth fighter with a twin-engine layout, single-seat cockpit, and internal weapons carriage designed to reduce radar cross-section.
The airframe incorporates diverterless supersonic intakes, serpentine inlet ducts to obscure engine faces, and canted twin vertical stabilizers. Naval-specific modifications include folding wings to reduce deck footprint, a twin-wheel nose landing gear to absorb catapult launch stress, and an arrestor hook for carrier recovery. The integration of a catapult launch bar enables compatibility with electromagnetic launch systems installed on Fujian. The aircraft has also been evaluated for operation on STOBAR carriers such as Liaoning and Shandong, indicating dual compatibility across all three Chinese aircraft carriers. Maximum takeoff weight is reported at 30,000 kg, with a combat radius of about 1,200 km on internal fuel.
These features place the aircraft within the same general class as the F-35C in terms of size and mission profile. The internal weapons bay is configured with six hardpoints, allowing the carriage of air-to-air missiles such as PL-10 for short-range engagements and PL-15 for beyond-visual-range interception. The developing PL-21 long-range missile is also associated with the J-35, indicating an intended role in extended-range air combat. Internal strike configurations include small-diameter precision-guided bombs and up to four 500 kg-class penetration munitions. Anti-ship and anti-radiation missiles can be carried internally in limited configurations, constrained by bay dimensions.
Externally, the aircraft includes six pylons, enabling a combined payload capacity estimated at about 8,000 kg, when internal and external loads are used together. External carriage significantly increases payload but increases radar signature and reduces survivability in contested environments. The ability to shift between internal-only and mixed loadouts allows mission-specific configuration depending on threat environment and strike requirements within a carrier air wing. Engine development has progressed through multiple stages, reflecting incremental improvements in thrust and efficiency. Early J-35 prototypes used the Russian RD-93 engine, which was later replaced by the Chinese WS-13E, delivering about 87 kN of thrust and improved fuel efficiency.
Subsequent prototypes incorporated WS-21 or WS-13 derivatives with thrust levels near 93 kN, serving as interim solutions for testing and early production. The intended production engine, the WS-19, is projected to deliver between 110 and 116 kN of thrust, enabling higher thrust-to-weight ratios and improved performance margins. As of late 2025, there was no confirmed operational deployment of the WS-19 on production J-35. Differences in exhaust nozzle appearance across observed J-35s indicate that multiple engine types may still be in use simultaneously. Carrier operations impose strict requirements on engine reliability, particularly under repeated high-stress launch and recovery cycles.
This operational constraint supports a phased engine introduction, where newer engines are likely validated in land-based variants before integration into carrier-based units. Engine maturity remains a critical variable affecting the J-35’s operational readiness. Production indicators point to a transition from prototype development to early manufacturing, but not full-scale deployment. In May 2025, J-35s with serial numbers 61820 and 61821 were identified and linked to a PLA Air Force test brigade based in Shenyang. In July 2025, multiple J-35 airframes were observed on an assembly line within Shenyang facilities, confirming active production. Additional aircraft bearing naval markings were photographed without standardized tactical numbering, indicating they had not yet been assigned to operational squadrons.
The presence of multiple airframes in production and testing suggests a low-rate initial production phase rather than full-rate manufacturing. This phase typically involves limited output for evaluation, pilot training, and system integration. The aircraft’s inclusion in the September 2025 parade indicates formal entry into the inventory, but not necessarily full operational deployment. The combination of production activity and incomplete unit assignment supports the assessment that the aircraft is approaching initial operational capability. Full operational capability will depend on sustained production, training, and carrier integration. The naval J-35 and the land-based J-35A share a common design lineage but differ in structural configuration and operational role.
The naval variant, the J-35 Blue Shark, features a larger wing area, folding mechanisms, a twin-wheel nose landing gear, and a catapult launch bar, all required for carrier operations. The J-35A uses a smaller wing, a single-wheel nose landing gear, and lacks carrier-specific hardware, reflecting optimization for land-based deployment. The development sequence shows that the naval variant entered development earlier, but the J-35A was publicly revealed first in November 2024. This sequence indicates that the land-based variant was maybe used to validate avionics, propulsion systems, and flight characteristics in a less complex operational environment. Like the F-35, the parallel development reduces program risk by allowing subsystem testing to proceed independently of carrier certification timelines.
This approach accelerates overall program progression while maintaining compatibility between variants. The shared design also facilitates potential cross-service logistics and maintenance efficiencies. In comparative terms, the J-35 program remains in an early stage relative to established fifth-generation fighter fleets. By October 2025, total production exceeded 57 units, indicating limited-scale output. The Lockheed Martin F-35 Lightning II has surpassed 1,200 delivered units and operates within a mature global support network. The difference in scale reflects disparities in production capacity, operational experience, and system integration.
Export variants such as the J-35AE have been referenced, but their viability depends on domestic fielding and sustained operational use. Export readiness requires demonstrated reliability, logistical support structures, and integration with command and control systems. The J-35’s effectiveness depends not only on its individual performance but also on integration with ISR assets, data links, and carrier strike group operations. Without these supporting systems, the introduction of a stealth fighter does not produce equivalent operational capability.
