As for my knowlege PS-05a is a round 60cm dish, and APG 68 is a eleptical 74*48 dish. This translates to 2827 sq cm vs. 2940sq cm. Not a bigger deal.

A future Gripen AESA will be tilted and futher back positioned, which by then can be alot bigger.

Good point. 😀 Why isn’t F-16’s AESA slanted like J-10’s is?

The WS-13 is still a generation behind the F414 by the data of that link.

My mistake. That’s not WS-13.

WS-13 http://en.wikipedia.org/wiki/Guizhou_WS-13

I would hope so, it came like 2 decades later.

Airframe technology has changed very little if at all since the 1970s. In all honesty, F-35’s airframe is no better than F-14’s. We do live in a Dark Age after all.

These MIG-29K already has IRST that JF-17 lacks.

IRST is not very useful in practice. It cannot do ranging unless it is coupled to a laser rangefinder, and even then the latter is affected by clouds and weather. These days with laser warning devices, IRST with laser rangefinder aren’t so silent anymore. IRST uses mechanical scanning which results in delays in tracking as is the problem with traditional mechanical radars. Last but not the least, IRST cannot search for surface targets. With the advent of AESA which simultaneously scan the air and the surface, have strong anti-stealth and anti-jamming capabilities, virtually no delays in tracking, long range, and little need for maintenance, IRST is fading into the backstage again.

JF-17 current lacks RD-33MK class smoke free engine. at best it will become at par with MIG-29K RD-33MKM engine at some future date.

AVIC’s FADEC http://j.imagehost.org/0592/0_20100109054042689O5s6.jpg

How reliable are these specifications from PAC (Pakistan Aeronautical Complex)?

http://www.pac.org.pk/jf17.html#

Length: 49 ft
Wingspan: 31 ft
Height: 15.5 ft
Empty weight: 14,520 lb
Maximum speed: Mach 1.6
G Limit : +8/-3

That’s the initial top speed. Production aircraft are at least Mach 1.8, if I’m not mistaken. Then again, F-35 has a top speed of Mach 1.6.

You can see how slanted forward JF-17’s air inlets are due to the DSI. Is it me or are Gripen’s air inlets slanted backward?

it flies with a giant moon on the underside. enemy forces will mistake this camouflage and think its a real moon. little will they know it is a lethal aircraft that will kill them.

Interestingly, the AVIC logo has a crescent shape. Maybe they are secret Muslims? 😀

One commonality will be that they will both have a swashplate AESA.

The Gripen NG will have a considerably more powerful engine. I don’t think the WS-13 (if it is ready by Block II) will have that range of power. However, presently the RD-93 gets 98 kN (see here)

while the RM-12 only gets 80.5 kN (?)

Given that WS-10 has nearly 30,000 pounds of thrust, and WS-13 is a smaller version of WS-10, I imagine it’ll generate around 22,000 pounds of thrust. 😉

Good question. I can’t seem to find anywhere that it does!! But it states that the NG will have one, and the NG demo also has one.

Good find. Thanks for sharing. JF-17 is getting AESA, IRST, and the new FADEC-equipped WS-13 engine this year, which should put it on par with Gripen NG in terms of avionics. It still remains to be seen if Gripen NG will have DSI.
