Imagery released on 13 February 2026 by the People’s Liberation Army Navy (PLAN) shows twin-seat Shenyang J-11BSH fighters from the Southern Theater Command conducting intensive over-water flight training. Published via China Military Online and relayed by People’s Daily Online, the photo series provides a rare open-source glimpse into how the People’s Liberation Army Naval Air Force (PLANAF) is refining long-range airpower integration into routine South China Sea operations amid sustained regional activity. The J-11BSH is the naval adaptation of the twin-seat Shenyang J-11BS, itself derived from the Shenyang J-11 family. The baseline J-11 traces its lineage to the Russian-designed Sukhoi Su-27SK, locally produced and progressively indigenised by Shenyang Aircraft Corporation. The J-11BSH retains the tandem cockpit configuration of the Su-27UB lineage, optimised for complex mission profiles and high workload maritime operations.
Open-source reporting indicates the J-11BSH incorporates Chinese-developed avionics, including a multi-mode fire-control radar with dedicated maritime search and air-to-surface modes. The aircraft is equipped with a digital glass cockpit and hands-on-throttle-and-stick (HOTAS) controls, enhancing situational awareness and reducing pilot workload during long-range over-water sorties. Such features are consistent with PLANAF requirements for persistent presence and flexible response in contested maritime environments. Like the broader J-11B/BS family, the navalised variant is assessed to be powered by the indigenous WS-10 turbofan series. The engine reportedly provides high thrust-to-weight performance, enabling strong climb rates and sustained supersonic cruise at altitude. Imagery from the February drills shows aircraft departing with both engines in full afterburner and landing gear extended, indicative of maximum-power take-offs aligned with long-range training profiles.

The J-11BSH is believed to employ the same air-to-air missile inventory as its air force counterparts, including the PL-8 missile and PL-12 missile, with later blocks likely compatible with the longer-range PL-15 missile. For anti-surface missions, integration with YJ-series anti-ship missiles and guided bombs is widely expected, offering a credible stand-off maritime strike capability aligned with the aircraft’s radar and payload capacity. Close-up imagery reveals two visible underwing stations per wing, with the outermost station carrying a short-range air-to-air missile, while wingtip rails appear unoccupied. The absence of external fuel tanks, targeting pods, or heavy anti-ship ordnance suggests these sorties prioritised handling, formation flying, and tactical procedures over water rather than full-scale strike rehearsals. This configuration aligns with a training emphasis on air combat manoeuvring and maritime domain familiarisation.
The PLANAF is assessed to operate approximately 40 J-11BH single-seat fighters and 32 J-11BSH twin-seat aircraft. While the carrier-based J-15 and land-based J-16 families often attract greater analytical focus, the publicisation of J-11BSH activity underscores the continued relevance of land-based heavy fighters in theatre-level maritime air operations. Their endurance and payload capacity complement carrier aviation and long-range bomber assets. By releasing imagery of J-11BSH maritime drills, the PLAN signals sustained investment in integrating long-range fighters into South China Sea routines. The visibility of these operations serves both training transparency and strategic messaging functions, demonstrating that land-based Flanker derivatives remain central to China’s layered maritime airpower construct alongside carrier air wings and other joint-force elements.
