This is the most up-to-date PLA radar brigades deployment map.

PLAAF deploys 30 brigades whereas PLAN only 3.

Taiwan faces at least three radar brigades. pic.twitter.com/TsrJXJopKg

I agree. This is fantastic! Note the correlation between the East (China) Sea ADIZ and northern-most PLAAF 3rd Radar BDE site and southern-most PLAN site. The ADIZ created a single integrated air picture from two air surveillance sectors. The area opposite Taiwan is very dense. pic.twitter.com/u70gIF29Wo
