There was a great hubbub after purported images of the J-36 fighter circulated on the Chinese internet. The jet aircraft, potentially a bomber, demonstrated extensive attention to stealth features. While perhaps the J-36 will not be considered a sixth-generation aircraft, it could certainly qualify as a fifth-generation platform.
New images of the J-36 have reached the public eye, and these give more insight into what could prove to be a heavy fighter, or a bomber.
Of note is the J-36’s nose section, which is very streamlined with the rest of the fuselage, and suggests that two pilots sitting in a tandem arrangement could fit in the cockpit. Additionally, viewing the J-36 from the side gives a fascinating look at the aircraft’s dorsal, or top, air intake outlet that presumably diverts air to the central engine.
The J-36: What We Can Guess
At first blush, one of the most notable aspects of the J-36 is its size. Compared to American stealth fighters such as the F-22 Raptor or the F-35 Joint Strike Fighter, China’s J-36 appears to be significantly larger.
An additional unique feature of the J-36 is its apparent three-engine design, which would be highly unusual during an age in which virtually all fixed-wing combat aircraft with more than one engine have even numbers of engines—from the F/A-18 Super Hornet, with two engines, to the B-52 Stratofortress, which sports a whopping eight.
While running on three engines could offer thrust and speed advantages, this design consideration could be attributed to weakness in China’s domestic aviation industry. Though it is not a lightweight in terms of aerospace technology, one area in which China’s industry has struggled is in the design and production of jet engines.
Though China has relied on Soviet and then Russian jet-engine designs, the country is making some progress in getting its own engines off the ground. However, the recent images of the J-36 could indicate that while progress is being made, a third engine is necessary to meet the aircraft’s desired performance requirements.
This has significant implications for fuel consumption.
The Indo-Pacific
Any combat in the Indo-Pacific would occur over great distances: wide stretches of bluewater ocean wastes cross thousands of miles in every direction. Those distances are surmountable for surface vessels, given enough time, but all except the most long-ranged aircraft would struggle. Their combat radii are measured in hundreds of miles, rather than thousands.
Internal storage space for aircraft would be of high importance. More internal space equals more fuel, which grants greater range.
Hence, the J-36 is relatively large. With the addition of a third engine, the J-36’s fuel consumption could be considerably higher than a dual-engine design.
Long-Range Strike and Strategic Reach
Whether the J-36 is a heavy fighter or a bomber of some sort is indiscernible at the moment. However, what can be surmised with some degree of certainty is that the jet places a premium on both stealth and range, as do many aircraft.
Take, for example, the U.S. Air Force’s upcoming Next-Generation Air Dominance program or F-47. If all goes according to plan, the Air Force would eventually introduce a larger, heavier fighter-like platform that shares some traits with the J-36.
The NGAD would eschew a tail, like its Chinese counterpart, in an effort to reduce the jet’s radar cross-section.
It would likely be optionally manned and able to function essentially as a command-and-control node, able to work with other extendable, attritable aircraft.
And like the J-36, the Next-Generation Air Dominance is expected to have the combat radius required to operate effectively in the Indo-Pacific—flying significantly farther than fighters such as the stealthy F-22 and F-35, or even the F-15.
What Happens Now on J-36?
The development of the J-36 and its anticipated long range points out a potential deficiency in the U.S. arsenal: air-to-air refueling.
While the United States operates the largest tanker fleet in the world, the majority of those aircraft are modified civilian airframes.
And while they have served well in uncontested environments, those aircraft are not as survivable in highly contested airspace.
During a war in the Indo-Pacific, tanker aircraft will be of incredibly high importance to keeping American jets in the sky, but they will likely be under great strain. Take, for example, the upcoming B-21 Raider bomber.
Its range is expected to be lower than that of the B-2 Spirit bomber—and the Air Force would like to acquire at least 100 B-21s, potentially more. The strain on the tanker fleet will be significant.
Fielding aircraft with a high combat radius could make the difference, and in the J-36, China appears to have taken note of that lesson.
