Good point there, Waylander-
Here's some of my general thoughts:
Origin:
I think that the origin of the new fighter, let's say weapon system, isn't going to play that big role anyway.
Remember, the Indians are already operating russian, french (Mirage 2000) and british (Harrier, anglo-french Jaguar) designs side by side, so they are open minded I think. Shouldn't be too much of a problem for the European contenders. Could be a bit of a problem for our American friends though.
Another point is that the Indians might want to diversify their suppliers a bit more which would make a point against russian planes.
General Layout/ Performance:
The IAF has lost hundreds of fighters during the last decades and might prefer a twin engine layout for safety reasons (Same thing with the German Luftwaffe which after that awful lot of starfighter accidents decided to never buy a single engined fighter again).
India is a huge country and it seeks to improve control over surrounding "blue waters", therefore any true MRCA needs to be a capable interceptor/ air superiority fighter with good range and speed. Given that all contenders do have a decent sensor suit and BVR capabilities and weapons, this too would make one of the twin engine solutions probable at least.
As far as "true MRCA" is concerned: Could be a problem for the Typhoon as there still is some development work to be done. But this point also requires a big weapon load, which some have, some haven't. IMO a true MRCA has to carry anti radiation missiles, bombs and air to air missiles at a time to switch roles during the mission.
Another thing is that I think the IAF definitely wants to have an edge over the PAF on a face-to-face basis which would rule out the F-16.
Politics:
As this competition is about 126 potentially expensive fighters and there are rumours around (see DID's coverage today) that it could extend to around 180 fighters, each of the contenders will pretty much do everything to win and as all of the involved potential bidders (USA, France, UK, Russia) are very experienced with sweetening defence contracts, that's gonna be an interesting competition! I think we too will see some interesting technology transfer and economical incentives here...
Last point: New and warming relationships are a good thing, but keeping old ones hot is just as good...
Which brings me to the conclusion:
F-16:
+ multi-role
+ warming indo-us relations
- range
- single engine
- PAF flies it
- old design, growth potential doubtful
F-18:
+ multi-role
+ twin engine
+ warming indo-us relations
+ potential powerful carrier plane for the indian carrier plans
- speed
- very ugly (complete waste of metal and electronics)
Rafale:
+ multi-role
+ very good performer
+ already strong defence ties (mirage 2000)
+ twin engine
+ potential powerful carrier plane for the indian carrier plans
+ availability
+ modern design
- further development in doubt as there are few users (France and India) and low numbers so far
Typhoon:
+ great performer
+ best dogfighter
+ already strong defence ties with the British
+ twin engine
+ modern design
+ enormous growth potential with lots of developments already on the way
+ sexy
+ availability
- multi-role not yet proven
- expensive
Gripen:
+ multi-role
+ new but proven design
+ offered by the British (see above)
+ low purchasing and operating cost
+ easy to maintain
- range and speed
- weapon load
- in some respects competitor to the Tejas
Flanker:
+ multi-role
+ twin engine
+ best range
+ very good performer
+ Flanker already in service
+ low price tag
+ very strong defence ties with russia
- old design
- diversification issues
- probably inferior to western contenders in terms of avionics (sensor fusion, situational awareness, etc.) and reportedly in ergonomics
Fulcrum:
+ multi-role
+ twin engine
+ good performer
+ low price tag
+ very strong defence ties with russia
- old design
- diversification issues
- probably inferior to western contenders in terms of avionics (sensor fusion, situational awareness, etc.) and reportedly in ergonomics
