For a bombing mission in enemy area whether you switch on your radar or not enemy radar will be monitoring you (unless you are a stealth aircraft) so it immaterial.
Read my post again...it specifies an EXACT scenario. Enemy radar detection can be evaded in certain(few) scenarios even by non stealth aircrafts.
@LKJ86 @Deino How credible is this site?https://www.china-arms.com/2020/01/ws-13ipe-for-fc-31/
WS-13IPE engine for FC-31 carrier-based fighter could be mass-produced in 2020

One design plan of WS-13 engine modification
Guizhou Liyang Aero Engine Co., Ltd. affiliated to China Aviation Engine Corporation posted the company’s key tasks in 2020 recently, one of which is the implementation of small-batch production of a new aircraft engine.
The outside world generally believes that this new engine is probably WS-13IPE (thrust-enhanced type), which mainly adds thrust on the basis of WS-13 engine in order to adapt to performance upgrade and improvement of fighters.
JF-17 Block-III
WS-13 is a medium-thrust turbofan engine developed by the Liyang company based on Russian RD-93 engine. It was originally planned for JF-17/ FC-1 fighter. However, before its successful development, the Pakistan Air Force had selected RD-93 turbofan engine for JF-17 fighter and established an overhaul line. After evaluation, the Pakistani side thought that the performance of WS-13 is similar to that of the RD-93 engine. And the entire logistics support system would almost be overturned and it would cost too much to replace the engines. Therefore, Pakistan decided to continue to use the RD-93 engine.
However, Liyang company did not abandon WS-13 in this regard, and continued to improve and increase the engine’s thrust. Liyang company believed that JF-17 Block-III fighters would undergo major changes, and will use new equipment such as source phased array radar and integrated electronic warfare systems. And the weight of the aircraft would definitely increase significantly compared to the first and second batches. So the need for a larger thrust engine is an opportunity for WS-13 engine.
FC-31
Besides, it was reported that FC-31 fighter was equipped with WS-13 engine with an afterburning thrust less than 9 tons, which is far from sufficient.
FC-31 fighter was originally planned to use a fourth-generation homemade turbofan engine, but this engine has just been developed, and it will take some time for the design to be finalized and mass-produced.
Liyang company decided to improve the thrust of the WS-13 engine as a transition for FC-31 fighter. The WS-13IPE thrust- enhanced engine adopts a relatively conservative scheme and retains the original four-stage fan, but the blades are swept forward to delay the airflow separation. This increases the fan speed and allows the engine to take in more air, thereby increasing the engine thrust.
After the improvement, the thrust of WS-13IPE engine could be over 9 tons, which can be used for JF-17 Block-III and can also meet the initial needs of JC-31 stealth fighters, especially if JC-31 is chosen as the carrier-based fighter, which would need engines with a higher thrust to carry its increased weight.
Indra EW equipment already in use with JF 17 block2 meanwhile Leonardo S.p.A. has been in continuous liaison with Pak for induction of it's gadgets in block 3. Turkish equipment may also be considered as Western. However US tech looks to be out of reach for Pak.
The news are released by Guizhou Liyang Aero Engine Co., Ltd. affiliated to China Aviation Engine Corporation from their official website about production of this engine. It con-incident with the recent debut of Blk 3. To claim is as unreliable is a not a correct statement.
I have always considered WS-13 to be a dark horse which would upset analysts' predictions someday. At 9500 Kgf, it is not something that can be dismissed easily. The only question would be about its longer term reliability.https://www.china-arms.com/2020/01/ws-13ipe-for-fc-31/

By western i meant US , British and french. and yes you are right.
It is not about the news but about the whole article piece being released by the concerned organization or the Block 3 and last para of FC-31 was just an analysis by the editor
Do not trust every opinion of Deino.
I don’t find @Deino ”unreliable” simple because of his experience of coming across all this since years. Off course you and @LKJ86 are as well as reliable or even more sometimes.
OK MAN!
