If
China is planning to build nuclear aircraft carriers using the CATOBAR system,
then it would be in need of a new carrier based aircraft. China’s current
carrier based aircraft lack the structural integrity to survive the forces
generated by a catapult launch. As we stated earlier, the development of an aircraft
carrier using the CATOBAR system by
China would be unlikely unless it simultaneously develops a more robust
aircraft.
The
J-31 is China’s fifth generation aircraft. Photos and videos of the aircraft
began to emerge in June 2012. It is a twin engine mid-weight aircraft designed for
medium to low altitude missions such as air interdiction and aerial bombardment
in contrast to its predecessor, the J-20, which is a high altitude fighter. In
December 2013 it was reported that the J-31 would be redesigned to have ground
attack capabilities.

Although
the J-31 is an evolution of the J-20 it is unclear if the J-31 will replace the
J-20. When comparing the missions for which both planes are designed they seem
to complement each other. This could mean that the People’s Liberation Army Air
Force (PLAAF), the Chinese air force, could operate both planes in the future.
Several news reports by China in September 2013 state that the J-31 is designed
for export to offer a low cost alternative to the US F-35 aircraft. With little
real information known about China’s weapon programs it is hard to judge if the
J-31 will indeed be an export aircraft to compete against the F-35 or see
actual service in the Chinese armed forces.
Several
sources mentioned that China might use the J-31 to serve on board of a nuclear
carrier. The J-31’s chief designer, Sun Cong, has said that he hoped that the
aircraft would follow his J-15 onto China’s aircraft carriers. The J-31 was
however developed for the PLAAF. There are no indications that the People’s
Liberation Army Navy (PLAN) was involved in its design. The J-31 is smaller
then the J-20 and more robust. It also shares several similarities with the
F-35C, the new aircraft for US Navy aircraft carriers and the British Royal
Navy. The twin forward wheels are a feature that is mainly found on carrier
based aircraft.

Conclusion
Although the J-31 was developed for the PLAAF,
and not for PLAN, the question remains if the J-31 is a suitable plane for
China’s future aircraft carriers. Several questions need a definitive answer.
Does China intend to use the J-31 in its armed forces or is it indeed an export
aircraft only? And if used by the PLAAF, will the PLAN decide to convert the
J-31 so that it can be used on board of its carriers?
No
matter what the answers are to these questions, the J-31 is not only a step
forward in Chinese aircraft design, it is also a step in the direction of
building a modern aircraft that can be used on aircraft carriers using the
CATOBAR design. Until China develops another aircraft suitable for this task,
the J-31 is an aircraft that is worth to be followed up on in order to know
what direction China’s aircraft carrier development program is going.
