J-20

China's low-observable fighter — significant less for any single engagement than for what its production rate says about the trajectory of the regional air balance.

Battlefield role

Air superiority and long-range interception, with reported emphasis on engaging support and enabling aircraft at range.

Strengths

Low-observable design, long range and modern sensors, produced in numbers that have grown steadily. Its existence and production rate are the clearest single indicator of Chinese aerospace industrial capability.

Limitations

Combat performance is entirely untested. Engine development has historically been the programme's constraint, and open-source assessments of its actual capability vary very widely — reflecting genuine uncertainty rather than analytical disagreement. Vigil publishes no inventory figures, basing or deployment information, and treats confident capability claims from any direction with caution.
