ZDK-03 Karakoram Eagle

ZDK-03 is an export AWACS system being developed for the Pakistani Air Force. This project was initiated in the early 2000. A Y-8 AWACS testbed (serial # T0518/Project 021) based on Y-8 Category II Platform was first discovered at CFTE in early 2006. Unlike KJ-200, this variant carries a traditional rotodome above its fuselage, with a mechanically rotating antenna inside. The PESA radar is thought to scan electronically in elevation but mechanically in azimuth. Therefore the Y-8 AWACS was speculated to be developed for the export market only as it appears less advanced than KJ-200 which features a fixed AESA radar. However this design does provide a true 360° coverage and carry a cheaper price tag. The AEW radar may be the product of the 38th Institute/CETC, but no details are available. The aircraft also features a solid nose and tail with MAWS sensors on both sides, as well as small vertical stabilizers attached to its tailplanes. Another two MAWS sensors are attached to the tailcone as well. Additional fairings are seen at the wingtips and the tail housing ESM antennas. The Y-8 AWACS protoype was promoted to Pakistani AF in 2006. After some negotiations a much improved design was developed based on PAF's specifications. The variant is now named ZDK-03 (ZDK means CETC) and is based on the new Y-8 Category III Platform featuring WJ-6C turboprops with 6-blade high efficiency propellers. It was reported in early 2009 that a total of 4 were ordered by PAF in a $278m contract. The first ZDK-03 prototype rolled out in November 2010 at SAC. Since then it has been undergoing test at CFTE (S/N 733). Another 3 were built by late 2011. ZDK-03 is expected to serve as the airborne command & control center for the JF-17 fighter fleet currently in service with PAF. However it does not have the secure NATO datalink installed to effectively command western fighter aircraft such as American F-16. Therefore ZDK-03 operates together with Saab-2000 in a "high-low" combination in order to coordinate various Chinese and western made combat aircraft effectively. The first ZDK-03 (S/N 11-001) was delivered to PAF in December 2011. The 2nd (S/N 11-002) is currently undergoing flight tests. A recent image (March 2012) suggested that at least one more ZDK-03 has been built.
 
great shot! where was this taken?



edit: is it genuine, or photo-shop image; i actually cant tell! not sure if i recognize the tail number

China has developed a plethora of AEW platforms. The Plaaf itself uses the “high end” KJ-2000, based on the Beriev A-50, and the smaller KJ-2000 based on the Xian Y-8 turboprop transport, with a “balance beam” AESA antenna like that of the Saab Erieye. China has also exported the Y-8-based ZDK-03 with a “saucer” radar array to Pakistan. These will be joined soon by the Chengdu/Guizhou Soar Dragon box-wing strategic UAV.

What the hell on earth this thing is ??
 
Oscar is the only person whom can answer this question, but i doubt if he will.

Im afraid I cant be any more helpful than you on this...
My contribution was on the datalink and protocol. Not what will be transmitted to it.
But.. to add something.. The fact about having to go through a ground station to talk may change.
There was an effort underway to allow partial communication between our western and Chinese assets.

What's keeping PAF at bay for having complete communication between eastern and western platforms?

If we look at immediate neighbor, they are are and will data link russian assets with western ones. So if ZDK-03 having western COTS communication gear, i'm still unable to comprehend what's blocking it's way to communicate directly with F-16 rather communicating with F-16 through ground station.
