AVIC-Chengdu J-20 Mighty Dragon

The Chengdu J-20, also known as Mighty Dragon, is a twinjet all weather stealth fighter aircraft developed by China’s Chengdu Aerospace Corporation for the People’s Liberation Army Air Force (PLAAF).

Variants

J-20A

J-20A is the first production variant of the J-20 platform.

Flight testing began with prototypes in late 2010, with maiden flight in 2011.

The variant entered serial production in October 2017. J-20A was incorporated into training units of the People’s Liberation Army Air Force in March 2017, and the combat unit in September 2021.

J-20S

The twin-seat variant of J-20, named J-20S or J-20B by defence analysts, is a version of J-20 in development.

J-20S was first spotted in October 2021, taxiing inside a Chengdu Aircraft Corporation facility in yellow primer paint and untreated composite, making it the first twin-seat stealth fighter in the world.

The twin-seat design allows the possibility for the second operator to conduct airborne early warning and control (AEW&C) missions, which J-20 would leverage its avionics and networking capability to provide battle space surveillance, battle management, and intelligence analysis.

The stealth fighter could act as a more survivable and distributed alternative to traditional airborne warning and command post aircraft.

In addition to aircraft teaming, a twin-seat configuration may also provide marginal benefits in pilot training and strike missions.

The advantage for a second operator includes the potential for better interpreting and exploiting the enormous sensory data that could overload the limited cognitive and processing capacity for a single human.

The back seat operator would focus on managing the manned or unmanned aircraft fleet, reducing the pilot’s workload in a contested air combat environment.

With increased automation and artificial intelligence in the aircraft system, the two men crew would likely be able to delegate more complex AEW&C tasks, absorb information, and make tactical decisions.
