Mirage 2000H, MiG-29UPG, Jaguar DARIN III - Medium Multirole Aircraft of IAF

Yeah, turns out the DARIN III program is not that expensive, it's the engine program that's expensive.

Honeywell is asking for exhorbitant amounts to integrate and then deliver the engines. Their offer is more than the price of a single MKI.

HAL claims they can cut the cost by half by doing the integration themselves. Even then it's an expensive proposition, although way cheaper than a single MKI.

I suppose the best option is to go for a slightly less powerful Adour engine.
Just a thought, How about the Turmansky R195:

India should just make peace with China, with our obsession for "cheap", Chinese equipment and our habits are a match made in heaven.

Your data is completely wrong. You do not even know what you have posted.
Reference
I haven't tested the thrust or measured the dimensions myself, but pretty sure there are references for the number posted.
For R195
Turbofan and turbojet engines

For F125 and Adour its pretty easily available

It is a turbojet, it would be a significant downgrade from the current Adour engine.

Plus it doesn't have afterburners.
Seems like adequate thrust, with a proper engine control module, with just controlling 28-44 operating range it would most likely be adequate.
What other engines are out there in the same range? Sorry I meant the R195 on the SU25 not R129.

what about the Turbo-Union RB199
fits close to the F125N : L 3.6m D: 0.72m W: 976.

It's still turbojet, acceleration and deceleration are going to scuk. SFC will scuk. Maintenance will scuk.

RB199 is too heavy. IAF is looking for something well below 700Kg. Plus dry thrust rating for Jag is 25-30KN. All these engines are too powerful.

The only engines available are from Honeywell and Adour. The other potential alternative is the XF5-1, but dunno how open the Japanese are when it comes to this.
 
Can we consider 2-3 squadrons of su34 to take over as low flying interdictor strike aircraft or would we have to set up new infrastructure for it.It has basically same body( except front) and engine as the su30.If its cost is affordable and HAL can use mki spares on it ..can we consider it?
We cant do it if we dont have spares match with mki though, dont need another new aircraft with its own logistics.

Either way we would still have same problems of adding more mkis,high maintainence and 2 pilots.
If they do go mki they need irbis,MAWS and al41 at least.But im sure what will happen is another HAL handout.Best option is more rafales.

The engine diameter is reported in two manners. The max overall diameter including AGB and the fan diameter. Your data does not make the difference between the two. The Adour has the fan dia while the F125 has the max engine dia.
 
HAL wants IAF to order MKI for their own goals, nothing to do with the IAF.

The best option to replace Jaguars is only AMCA and Rafale.

Fully and wholeheartedly agreed.

Su-30 as a Jag replacement makes no sense. Rafale on the other hand is perfect due to a variety of reasons -

> Low altitude flight performance of Raffy cannot be matched by Su-30, which makes it the ideal DPSA
> The MKI upgrade is not finalized. If we buy more Su-30s, they won't really be an upgrade in terms of tech to a DARIN-3 Jag until after we pay for a deep upgrade later on. In certain cases like the lack of an AESA, they'll actually be a downgrade (Jag already certified ELM-2052). The IAF Rafale F3R standard which we already paid for & finalized meets all our needs out of the box.
> Rafale inherently a more survivable platform, both due to EW and signature reduction. Neither of which Su-30 can compete with.

The MKI apparently has some stability issues at low altitude. Plus its autopilot isn't as advanced as Rafale's. And without MAWS, it's in danger of being killed by IR-guided SAMs. And the radar can only track 2 ground targets at a time.

Earlier, even with the above problems, the Jaguar DARIN I and II were inferior to the MKI, so replacing those with MKI was fine. But, as you're pointed out, the MKI can't replace DARIN III.

Honeywell knows the IAF doesn't have much of a choice, hence the ridiculous pricing.

Well, in that case, doesn't it make sense to mothball half the fleet of Jaguars , order around 40 MKI's preferably in Super Sukhoi configuration and wait for the HTSE to be certified before updated iterations to power the Jaguars are introduced which maybe anywhere between 4-6 years from date?
 
Can LCA perform the all duties of Jags in terms of weapon load & range?

If yes, then we should get our own LCAs.

LCA Mk1/1A, no chance. MWF, partly yes, but only in terms of avionics. Jag is more survivable because of twin engines. You want two engines for deep strike aircraft so that you can at least limp home afterwards. F-15E, Su-34, Su-30, JH-7 and Tornado are some examples.

The Jaguars are going to leave service from 2028 onwards anyway. The planned 200-250 Rafales are supposed to take care of their exit.

There is no immediate need to replace the Jaguars. It's just that the DARIN IIIs, which are supposed to be operated until 2042 will have to be replaced much, much earlier, that's all, and until te engine upgrade comes through, it will be a real dog to fly.

Also, the Super Sukhoi is better utilised towards the air superiority mission than deep strike. So any "replacement" of the Jaguar with Super MKI would mean these Super MKIs will be used for air superiority while the older MKIs will get stuck with deep strike, and the older MKIs are not entirely suitable for deep strike.

If Honeywell fails, then IAF will have to go back to Adour for an inferior engine, and they may also try to do the same anyway. HAL's engine is many, many years away.
