The J20 offers many benefits for the military. The twin-seat version of the J20 is perfect for electronic warfare and bombing. It is also equipped with a domestic engine that eliminates the dependence on Russian engines. It could be used in surveillance and electronic warfare as well as command of wingmandrones. The United States Air Force could make use of this type aircraft in many different circumstances.

Chinese military is currently developing the J-20 stealth fighter, which can fly at speeds up to 2,100 kph. It features two lateral missile docks with four hardpoints each, and an internal gun. It has an integrated infrared/optic track and search sensor mounted on the chin and an AESA radar.

Metamaterials
CCTV recently aired an episode on military aircraft development called "Great Country’s Great Weapons". It revealed the development and use of metamaterials within its cockpit. Among the planes that could benefit from this technology are J-20 and J-16 fighter jets. In addition, the J-15 carrier-based aircraft has already entered the mass production stage.
Lock-on capability after launch
The J-20 features four PL-15 long-range medium-to-long range air-to-air (AAMs), The missiles are very similar to the American AIM-120D AMRAAM but are equipped with dual-pulse engines and AESA. They are designed to penetrate enemy fighter cover, and destroy their enablers.
Conversion of air-to ground weapons
During a recent flight demonstration in China, J-20 combat aircraft demonstrated a new missile-launch mechanism. It is simple and efficient. J-20 number 022 was equipped with a short range air-to–air missile (also known by the PL-10). The missile was then detached and released from the aircraft using an ejection mechanism.
