how does the fc-31 compare to other stealth fighters?

 The FC-31, also known as the J-31 or J-35, is China's second indigenous stealth fighter and is often compared to other stealth fighters, particularly the American F-35 and F-22. Here's how the FC-31 compares to its counterparts:

Stealth Capabilities

Both the FC-31 and the F-35 incorporate stealth technology to reduce their radar cross-sections. However, the F-35 is known for its advanced and integrated stealth design, which potentially provides a higher level of stealth capability

. The FC-31 has a stealth aerodynamic design and likely has a stealth coating, but it is too early to tell if it can match the F-35's stealth performance

Engine and Performance

The FC-31 is a twin-engine aircraft and has been known to use two types of engines, including the Russian-made RD-93. The engine's thrust-to-weight ratio indicates that the FC-31's engine is heavier and provides lesser thrust compared to some of its counterparts

. The F-35, on the other hand, uses the F135 engine, which is not only more powerful but also more advanced in reducing radar and infrared signatures

Weapons and Payload

The FC-31 has a reported weapons load capacity of 8000 kilograms, with 2000 kilograms stored internally and 6000 kilograms carried on external hardpoints. In comparison, the F-35C can carry more than 2267.96 kilograms of internal weapons or more than 8164.66 kilograms in total

. The FC-31 can be fitted with one internal cannon, two internal weapons bays in the fuselage, and three external hardpoints on each wing

Sensor Fusion and Avionics

Sensor fusion is a critical aspect of fifth-generation fighters, enhancing a fighter's situational awareness and combat effectiveness. The F-35 is known for its advanced sensor fusion capabilities. There is skepticism about whether the FC-31 can match the sensor fusion advantages held by the F-22 and F-35

Design and Development

The FC-31's design suggests it might have been designed for carrier use, with some visual similarities to the F-35 and F-22. It is intended to operate from China's forthcoming Type 003 aircraft carrier with an electromagnetic catapult system

. The F-35, meanwhile, has three variants designed for different types of operations, including conventional takeoff and landing, short takeoff and vertical landing, and carrier-based operations

Overall Assessment

While the FC-31 represents a significant leap in low-observability over previous Chinese designs, it is not expected to match the stealth capabilities of America's F-35 or F-22, largely due to America's multi-decade head start in stealth technology

8

. The FC-31 could likely challenge America’s fourth-generation non-stealth fighters but its performance against the F-35 remains to be fully assessed

2

.In summary, the FC-31 is a significant development in China's military aviation, offering improved stealth and combat capabilities. However, it is generally considered to be less advanced than the American F-35 and F-22 in terms of stealth, sensor fusion, and overall performance
