Shenyang FC-31

China's aviation industry has been a topic of global interest, particularly when it comes to its endeavours in stealth aircraft development. Among these, the Shenyang FC-31 has gained significant attention. In this article, we'll delve into the history, purpose, and future prospects of the FC-31.

The FC-31 vs. J-20 Naming Confusion

The FC-31, despite its prominence, has often been incorrectly referred to as the "J-31" or "J-21" by various sources. This naming confusion stems from the complex landscape of Chinese military aircraft designations. The important thing to note is that the FC-31 is not a project actively developed by the People's Liberation Army (PLA). Instead, it is a self-funded technology demonstrator, originating from the collaboration between Shenyang Aircraft Corporation (SAC) and AVIC (Aviation Industry Corporation of China). Consequently, terms like "J-31" or "J-21" are inaccurate when describing this aircraft.

The FC-31's Unpredictable Arrival

The FC-31's introduction to the world of aviation was anything but conventional. Unlike its predecessor, the J-20, which had a buildup of rumours and speculations leading to its unveiling, the FC-31 appeared seemingly out of nowhere in 2012. This surprise unveiling was marked by photographs of a partially disassembled airframe being transported on Chinese roads, shrouded in protective covers, concealing its silhouette and design. Initially, many in the aviation community dismissed this as possibly a disassembled trainer aircraft or a less ambitious project. However, in September of that year, photographs taken at SAC confirmed the existence of a complete and assembled aircraft, sporting serial number 31001, and bearing a striking resemblance to the earlier speculated "F-60" model. This aircraft made its maiden flight on October 31, 2012, becoming the second stealth fighter design actively flown by China at the time, following the J-20.

The FC-31's Export Prospects

When the FC-31 first came into the spotlight, it was initially considered a potential export-oriented fifth-generation fighter. The relatively open profile of the FC-31 at various airshows and arms expos, as well as promotional efforts by AVIC, created an impression that the aircraft might be targeted at the international market. However, over time, it became apparent that the export prospects for the FC-31 were limited. This was due to several reasons.

Firstly, developing the FC-31 into a fully-fledged fifth-generation fighter suitable for export would require substantial additional work. This would involve improving the aircraft's avionics suite, weapons systems, and other crucial components. Moreover, it would necessitate the creation of maintenance and infrastructure facilities, as well as extensive flight and systems testing. These factors would demand significant financial investments, time, and a willingness to tolerate risk. At the time, the PLA had not expressed interest in the FC-31 or any of its derivatives, resulting in a lack of PLA commitment and funding. Furthermore, there were no foreign nations willing to invest the substantial resources required for the FC-31's development into a mission-ready fighter for export. Consequently, it is likely that AVIC, SAC, and the Chinese government did not harbour serious intentions of promoting the FC-31 as a dedicated export fifth-generation fighter. Instead, it served as a means of showcasing AVIC's potential for developing future fifth-generation fighters that might be offered on the international market, as well as initiating discussions with potential customers to gauge their interest.

FC-31 as a Technology Demonstrator

Amidst the confusion surrounding its purpose, academic papers from SAC have suggested that the FC-31 primarily functioned as a technology demonstrator. This role involved showcasing advanced manufacturing technologies, including additive manufacturing (3D printing), and experimenting with new structural principles aimed at reducing cost and weight. Rumours have also hinted at the FC-31 potentially incorporating improved stealth technologies to enhance ease of maintenance and operation compared to its counterpart, the J-20.

FC-31's Transition to Carrier-Based Fighter

While its initial role as an export fighter may not have materialized, the FC-31's story took an intriguing twist. It became evident that the PLA Navy had selected an FC-31-derived airframe for development into its carrier-based fifth-generation fighter. This variant is often referred to as "J-XY/J-35" in reference to the past "J-XX" nomenclature used for the J-20. However, this choice brought about its own set of challenges and complexities, including questions about the aircraft's size and potential numerical designations.

J-XY/J-35's Development

The development of the J-XY/J-35 variant of the FC-31 has been a topic of keen interest. While there were tentative expectations of its unveiling around mid-2021, it remains subject to factors such as the global pandemic and global stability. Assuming a 2021 first flight, the development of the aircraft would likely take at least four to five years, suggesting the earliest possibility of initial production around 2026. This timeline could potentially be expedited by leveraging the years of prior flight testing that FC-31 airframes have undergone from 2012 to 2021. Additionally, utilizing existing, mature subsystems already employed on the J-20 could contribute to a faster development pace.

J-XY/J-35's Weapons and Avionics

The J-XY/J-35 is expected to retain a similar main ventral weapons bay configuration as the FC-31, resembling the setups seen on the J-20 and F-22. However, it is unlikely to feature dedicated side weapons bays like the F-35. While the exact dimensions of its weapons bay remain undisclosed, there is a possibility that the J-XY/J-35 may be capable of carrying powered strike weapons, similar to those accommodated in the ventral bay of the J-20. In terms of sensors and avionics, it is highly likely that the J-XY/J-35 will feature derivatives of the same suite employed on the J-20. Given the potential overlap in production between the J-20 and J-XY/J-35, both aircraft may share common subsystems.

Land-Based J-XY/J-35 Variant

An intriguing possibility lies in the development of a land-based variant of the J-XY/J-35. Such a version could leverage the extensive development work undertaken for the carrier-based model. The land-based J-XY/J-35 could potentially serve as a medium-weight fifth-generation fighter complementing the larger J-20 in the PLA Air Force's arsenal. However, the pursuit of such an aircraft remains uncertain, and it is unclear how it might compare to other potential single-engine fifth-generation fighter options.

Export Potential

Should a land-based variant of the J-XY/J-35 materialize, it could open up possibilities for export in the late 2020s. This export version would be appealing to nations seeking fifth-generation capabilities but unable to acquire F-35s due to geopolitical alignment or budget constraints. Notably, the Pakistani Air Force has shown interest in such capabilities, but it is concurrently pursuing its indigenous fifth-generation project, Project Azm.
