yes. But what if we want to increase power output???

I'm assuming you mean during flight? You can't afaik. Twin engines might produce twice the maximum rated electrical power but that's for redundancy purposes. Each of super hornets engine produces a little north of 75kW, which is enough for the aircraft's requirements. External modules (targeting and jamming pods) are mounted while keeping the electrical power available under consideration. If more power is required than the aircraft's output then other solutions are employed such as the jamming pods of the growler, which generate their own power.

What if we change the module which produces power??? Will it affect the thrust produced by the engine???

There are two parts of the question you have put forward.
1) power sources in an ATR72
2) increase of power output.

Thanks, but I am talking specifically about fighter jets.

Changing the module should not have any effect as long as required power of the aircraft and the modules combined does not exceed the max output from the engines.
Regarding thrust, in theory thrust should decrease as more power is drawn from the generator but in practice the change is miniscule enough to be disregarded.

Thanks, but I am talking specifically about fighter jets.

In theory the principle remains the same. The limitation is thrust produced by the engine and the weight of the aircraft as there is always a compromise.

The German Government has granted Rheinland Air Service (Mönchengladbach) an export licence for a “Torpedo-fighter-plane” to Pakistan. That would be another Sea Eagle. I have no idea if that will be a Pakistani owned ATR being converted, or a secondhand aircraft will be added to the fleet.

We have recently given a tender for the jet

That looks more like a Boeing 737 class aircraft, I wonder if that has any connection with the RAS Sea Eagle conversion?
MTOW of 737 is 120.000-130.000 lbs, an ATR72 of about 50.000 lbs.
Also the range of an ATR72 is much less I think?

This is likely RAS-72 Sea Eagle. The jet-powered LRMPA is still a ways out.

We have extra aircraft for it?

I know 2 ATR-72 are flying for the PN as cargo/passenger aircraft. Maybe one of those might be converted. But it is also possible RHeinland Air Service will buy a (secondhand) ATR72 for Pakistan

Sir, it seems like ATR-72 is not the aircraft that PN is considering. If we look at the tender then it is clearly mentioning an aircraft with MTOW and range far more than what ATR-72 offers.

In my opinion A319LR or A220-100 are more appropriate. A220-100 is powered by P&W Canada similar to the ATR's hence supply chain and maintenance will not be a problem. It is also cheaper in price as per the 2018 price list of Airbus ..Link file:///C:/Users/ADEEL/Downloads/Airbus-Commercial-Aircraft-list-prices-2018.pdf

An interesting video regarding A220.

hmmm...I think we're talking about 2 different things.

1. There's the twin-engine tender for an LRMPA
2. Germany approved the sale of a 'torpedo-fighter-plane' to Pakistan.

I'm saying No. 2 is referring to another RAS-72, that's the only 'torpedo-plane' program we have with Germany.

The twin-engine jet for the LRMPA is a separate program, likely to be designed, integrated and tested in Pakistan. I agree with you, the PN is clearly looking for a larger plane. However, I don't think they'll get A220. Unfortunately, it is too late for that and now that plane is in Airbus' hands. When it was still with Bombardier, maybe...

That said, the Bombardier Global 6000 or 7500 are a good bet. They're slightly lighter than the MTOW requirement, but we know (from the Saab Swordfish) that turning it into an LRMPA is doable. Moreover, Canada is evidently fine with countries using the jet for military purposes, even Turkey's using it for the HAVASOJ EW/ECM aircraft.

The PN will likely go the Bombardier route, either brand new from factory or through third-party companies.

But if we follow the tender requirements to the letter, then it boils down to the Airbus A220-100 or the Embraer Lineage 1000E. Yes, Boeing bought Embraer's airliner division, but the Lineage 1000E actually belongs to Embraer's VIP line (which Embraer still owns).

Sir, may be you are correct that these are two separate programs and yes PN does require 2 more RAS72 to replace the existing F-27's. Not long ago there was news regarding the upgrades for the ATR72-500 to ATR72-600 specifications for the PN. There is no news in this regards hence one might consider that one more of the existing ATR in the Transport fleet might have gone through with the upgrade hence the German approval.
Or
The wording that has been mentioned is "Sale of a Torpedo-Fighter-Plane" could also be taken as this is not based on the existing RAS72 Torpedo-Plane program but a new one hence a new tender was published specifying LRMPA. Keeping in mind if PN could use the same equipment that is already approved for the RAS72 on different platform i.e LRMPA than PN might have some amount saved. (PAF model used for SAAB).

This would give PN a new capability and required area coverage with limited funds.

Embraer Lineage 1000E

No doubt this aircraft might be available still it is too underpowered as it is based on the E170 - E-195 having the longest fuselage.
