According to reports from multiple media outlets including CCTV, footage of Chinese carrier-based aircraft training inadvertently revealed the catapult-launched version of the J-15 fighter jet. Many netizens compared two images side by side: the J-15 with its duck-style wings, arresting hook, and other distinctive features.
During this training session, it became apparent that the J-15 variant seen overhead and on the deck was noticeably different from previous versions. It is said that this aircraft is called the J-15B, an improved model previously referred to as the J-15T.
Several differences from the previous J-15 are evident from the photos.
The airspeed probe on the nose has disappeared, presenting a much cleaner appearance. Previously, aircraft had a probe resembling a dagger on the nose, which was an instrument for comprehensive air pressure detection. Many aircraft integrated the probe, known as an L-pipe, onto the fuselage, eliminating the need for the dagger-like probe on the nose.
Some speculate that the absence of the probe indicates the installation of a more advanced radar. Whether these two points are related requires further verification. Generally, phased array radar has minimal interference with the probe. However, the disappearance of this device indicates progress and development in its external design. If a more compact L-shaped airspeed probe is installed, then the traditional probe can be omitted.
The most significant feature distinguishing the two aircraft is the absence of the nose probe. In the future, when identifying the J-15, as long as there is no probe on the nose, no sharp tube, it indicates a new version.
The front landing gear doors are double doors. Previously, during takeoff, the J-15 had a single large door on one side. Now, with smaller double doors, the overall size is reduced. When the large door unfolds, it increases the radar cross-section. By reducing its size and using double doors, it contributes to the aircraft’s stealth capabilities.
Thirdly, the front landing gear is thicker and sturdier. Previously, during ski-jump takeoff, the force was balanced. However, with catapult takeoff, the electromagnetic catapult exerts significant force, requiring sturdier landing gear to withstand sudden forces.
The J-15B has undergone significant changes compared to the previous J-15. Some speculate that it may have a new engine, although this remains unconfirmed. Examination of the engine’s nozzle and comparison with other dimensions of the aircraft will clarify whether it is the previous or a new engine.
With the confirmation of this catapult-launched version, it not only signifies advancement in fighter jet models but also accelerates the sea trials of the Fujian carrier. Recent photos of the Fujian carrier have generated excitement. The presence of the Red Flag-10 and the “dense array” with protective covers indicates smooth maintenance and inspection of weapons and equipment.
After the next step of sea trials, the efficiency of the catapult on the J-15T will need to be tested. If the J-31 and J-35 are not yet ready for deployment, then the J-15B, the catapult-launched version of the J-15, can undergo precise evaluation of reliability, practicality, and fault-free operating time.
This takeoff method demands proficiency from pilots and shipboard operations. Technological advancements can be validated through testing in complex maritime environments. The emergence of this carrier-based aircraft indicates significant aerodynamic and radar developments. If a new engine is installed, it achieves power and engine autonomy. If the catapult is validated during sea trials, it marks a significant milestone.
The appearance of this aircraft demonstrates another significant step in China’s innovation in carrier-based aircraft manufacturing. Following the J-15T, the next expectation is likely the J-35. (Du Wenlong)
