Air cooled part is on the pic on page 77 right bottom
Prototype means prototype of KLJ7AWhat is also interesting and if my interpretation is correct the production radar has 65% more range than the prototype (81NM) giving a range of almost 134NM or 250km for a 5sq m target! It’s a beast!
Also I didn’t find the air cooled part. Can you point out the page?
By prototype couldn't it have meant the radar on the prototype JF-17 i.e. the mechanically steered KLJ-7v1? And the more than 81NM range stated in the article is for the current one i.e. KLJ-7A?
Also, this could be the open market export version specs. Because why should we reveal what prowess our own Thunders would be having in the context of radar ranges?
