If Russia objects the engine being sold to another country, it would have to be a country that was going to purchase a Russian fighter as the closest alternative. Or a country where Russia normally exerts an influence over i.e. pressures to buy Russian anyway. These potential JF-17 operating countries don't really exist. Malaysia will not be buying Mig-29s and if they get tempted by Mig-35s while choosing JF-17, there's a chance it will send the Russians into diplomatic action. Such a bridge can be crossed then. For now, JF-17 has made a few export sales and no Russian hint of cutting supply at all. If more sales come and Russians complain for some of the reasons discussed, they can use WS-13 or possibly the better engine that will replace the RD-93/WS-13.

There are a number of good reasons of not adopting IRST in Block 3 but frankly IMO, funding sacrifice for Project AZM is not one of them because the nexus is too premature given where AZM is at currently.

I think it's not only an issue of funding though. Most of the organization right now is geared towards building and mainstreaming the Thunder platform. As those resources free up they will be redirected towards Azm. So if including the IRST adds another year, or increases the cost considerably, then it won't be worth it.

We have to remember the original scope of the project. The Thunder was never supposed to be the top-tier fighter for the PAF. It was a 4th gen replacement for legacy 3rd gen A/C. It doesn't even replace our vipers.

I don't understand the reasoning behind the need for IRST especially the argument against stealth targets. Firstly there are no existential stealth threats against the PAF in the immediate or medium horizon. Secondly, how IRST could actually be meaningfully deployed is never articulated.because there are several different technological levels in IRST adoption. The current IRST detection range against frontal aspect is between 35 to 70 kms depending on the IR technological adoption but these numbers come with it a range of unknown assumptions and issues which are seldom acknowledged. For example, the OLS-35 in the SU-35 is a scanning IRST and probably 15 years behind in IR technology and has a frontal detection range of 35 kms.

In contrast, PIRATE which is adopted in the Eurotyphoon uses staring IRST and reportedly has a frontal detection range of 70 kms.

The question is if the JF-17 was getting IRST what technological IR was it going to get because IRST adoption brings with it cost and the significant processing burden that comes with such technology? More importantly, how could the PAF benefit from it given the cost and the technological limitation? The biggest drawback of IRST is that its search function is time consuming because of its very narrow FOV and long range search capability is therefore inefficient. Western platforms use IRST as an integral piece of sensor fusion and the search area its cued to a more narrow box.

I actually never considered IRST to be a counter to 5th gen at all. If I remember correctly, this whole myth started a decade ago, when the Russians started bragging that their IRST's can detect the Raptor or something (which always made me laugh.)

With that said, there is no doubt that IRST has a place against the masses of pre-AESA 4 gen A/C with pulse dopplers blasting the airspace. And that is the target set the Thunder is designed to counter, so it is a valid concern. I still think that a podded IRST for the Block III, a few per squadron, would be a good tool. But I wont sacrifice time for it.

The plan was clearly to mainstream the Thunder as soon as possible, replace our 3rd gen with the 4th, and then move on to 5th. Also, I don't think it's only about when the IAF gets 5th gen. The PAF would get 5th gen tomorrow if it could, considering the IAF has made its intentions clear on acquiring 5th gen tech already (even if unsuccessfully).

Could also be PAF not being satisfied with the IRST offered. Perhaps the performances are limited by the size constraints. Who knows. Maybe CAC and suppliers only offered IRST that were of lower spec and performance compared to the latest ones on J-10s and J-16s. Maybe those won't fit.

I doubt that it was restricted, because the J-10C is approved for export, and the JF-17 is also a Chinese export product, basically.

I'm confused about the availability of podded IRSTs though. I'm not sure what systems China produces, since it uses integrated IRSTs itself.

AZM is OT and I would refrain from further comments. As you pointed out, the JF-17 is meant to be affordable and in numbers. In this respect the project itself is achieving its goals. IMO, the PAF is being faithful to its mandate and adding IRST would add cost without the corresponding benefits.

I actually never considered IRST to be a counter to 5th gen at all. If I remember correctly, this whole myth started a decade ago, when the Russians started bragging that their IRST's can detect the Raptor or something (which always made me laugh.)
Historically The Russians had been a stronger proponent of IRST with the OLS series as a way to offset the US advantage in radar technology. However, the older OLS series were based on uncooled/cooled/non imaging IR technology that was cheap but had limited utility. Even the OLS-35 is based on scanning IR not staring and the one on the SU-57 is reportedly based on QWIP. The revival of interest in IRST in the West is due to advancements in processing capabilities The planned AESA with the Block 3 will naturally demand an upgrade to its processors as AESA is signal processing intensive. Adding IRST will add further burden onto a system that is already cost constrained. .

With that said, there is no doubt that IRST has a place against the masses of pre-AESA 4 gen A/C with pulse dopplers blasting the airspace. And that is the target set the Thunder is designed to counter, so it is a valid concern. I still think that a podded IRST for the Block III, a few per squadron, would be a good tool. But I wont sacrifice time for it.
A podded IRST in my view is a better future route for the JF-17 for multiple reasons including :
1)IRST is mission set dependent. An embedded system is wasteful as opposed to a podded system that can be mated to the platform when needed.
2)IRST is typically single IR band unless you can afford the luxury of dual band IR with MWIR/LWIR. LWIR band is cheaper and typically suited for air-to-air missions. The JF-17 is predominantly multi role and using a podded system is a more optimal deployment of limited resources.
3)IR data can be data link and shared within a formation dispensing with the need to be embedded within each platform.

It would be pretty simple and straight forward for China to take existing integrated fighter IRSTs and put it in a podded form.

This does bring up a somewhat related questions - any news on the rumoured extra intake hardpoint(s) for the BLK3?

Last I heard, they were planning to add one new hardpoint under an intake for pods.

Is that confirmed? Also, it always seemed both strange and short sighted to add only one intake hardpoint.

Would make far more sense to add a pair.

That way you can add two pods without sacrificing serious hardpoints, which will be invaluable for both AA and AG missions.

For AA, a jamming pod and an IRST pod would be a perfect combo.

For AG, you can have a targeting pod and a jammer, or radar navigation pod if you want to do nap of the Earth flying.

AFAIK know, this is the first clear image of a PAF JF-17 - here number 16-223 - carrying the ASELPOD Advanced Targeting pod.

beautiful

so it means now Block II can proceed to ground attack with fire and forget capability

not like those silly Mirages with H2 and H4 which have be guided all the way to the target

ASELPOD ON JF-17 COMFIRMED!
It was recently confirmed through Aselsan's Annual Yearbook for 2017 that the company's ASELPOD advanced targeting pod was successfully integrated to and tested from the Pakistan Air Force’s (PAF) JF-17 THUNDER multi-role fighter in 2017. The PAF ordered eight ASELPODs for U$25 million from Aselsan in 2016, with deliveries in November 2016 as well as September and February 2017.

Pakistan was the launch export customer of the ASELPOD, having procured the ASELPOD in a bid to provide the JF-17 with precision-strike ground attack capabilities. By deploying the ASELPOD, the JF-17 is able to deploy laser-guided bombs and, if equipped, laser-guided air-to-ground missiles.

Though Aselsan saidat IDEAS2016 that it anticipates additional ASELPOD orders from Pakistan, it is unclear if the PAF has made another order. That said, the Daily Sabah newspaer reported that Pakistan ordered another batch for $24.9 million, citing Aselsan’s disclosure on the Turkish government’s Public Disclosure Platform (KAP) in May 2017.

It is unclear if Aselsan’s JF-17 activities will expand beyond ASELPOD, even though the company offers tactical data-link terminals, integrated avionics and electronic warfare and electronic countermeasures (ECM) systems for combat aircraft.

The forthcoming induction of the T129 ATAK attack helicopter (story

) and Agosta 90B submarine upgrade programmes will give Aselsan more opportunities in Pakistan, be it electro-optical and infrared (EO/IR) turrets, electronic support measures (ESM) systems and, potentially, radar and sonar sensors.

Since 2010, Aselsan had primarily supplied software-defined radio (SDR) kits to Pakistan.

One thing the PAF Chief, ACM Mujahid Anwar Khan said on Monday. ‘Whatever capabilities the Indian Air Force acquires, like the Rafale/Meteor BVR combo’ he said, ‘the Pakistan Air Force will match it - the balance has to be maintained. Have no doubt about that.’
