Odd that the left wing tip is in primer?? you've gotta wonder about these little things, perhaps they changed a radar receiver or MAWs antenna??? Those LevCons prolly have a titanium leading edge?? anyway, these girls are finally making progress.

bro if I were you, I'd be careful: as I said, I don't know how old the picture is (its description says '2016' but the ground looks to me as in Spring)
actually now I checked

the plan is to deliver five PAKFAs to the Russian Air Force in 2017, so I have a sensation of

What's with the opening on the root of the stabilizers?

Excellent question Kwai, you will notice they are symmetrical, and each opening is ducted with one duct likely going to radar/avionics cooling at the base of the fin and probably further ducted into the stinger, the lower duct would like by a direct injection of very high pressure air injected to the "afterburner cans" in order to improve combustion and cooling and increase overall thrust??

That is on top of the fuselage, and by the aft fuselage much of the lower pressure air on top of the aircraft has begun to "reattach" and the pressure is coming up, so very those ducts move a lot of air and likely accelerate and lower the temperature of that air, so cooling woud seem to be the order of the day.

It began mass production of the radar for the PAK FA AFAR

General Director of the Research Institute of Instrumentation (NIIP) to them. Tikhomirov, Yuri White told that created the first production models of the radar complex fifth-generation fighter T-50 (PAK FA) with an active phased array (AESA).
As he told in an interview with Tass White, flight tests of the new radar "are without any comments."
He also said that in the interests of the Navy planned to build sonars for unmanned boats and towed funds for military ships. "We are confident that these trends are promising, and we hope that in the near term prospects will be supported by appropriate contracts," - said CEO NIIP.

Attention Fleet, according to White, is also attracted to the development interoferometricheskogo sonar allows you to keep shooting bandpass bottom relief (analogue multibeam, allowing to obtain a high-quality acoustic and topographic image of the bottom at the same time)

Recall, a fifth-generation aircraft flight tests (PAK FA T-50) with a unique on-board radar system with an active phased array antenna (radar AFAR), consisting of airborne avionics began in August 2012.

Meanwhile, in August 2015 the PAK FA offered to equip the radar based on the use of radio-optical phased arrays (ROFAR).
