No Benny , its not maths .
Many of us here will be not be aware how defence deals , Offsets, operational costs etc work .
And how the costs of aircraft are matter of fluctuation while purchasing and their life-long operation.
200 mill for Eurofighter involves everything , if you calculate everything for Gripen it will similarly come out to 166 mill.
Remember when you purchase a jet its not only Jet that you purchase , you buy its Support+Spares+Weapons+Training equipment+Logistics etc whole lot of things .
Just like a laptop with 5 Year service warranty and associated accessories .
What most people on Forum dont understand is the Flyaway cost f the jet and Operational cost of Jet when inducted in active service
Here is a link that will give you idea how costs are currently in world market.
Brazil AF Chief: Fighter Pick By End Of March idrw.org
Not the prices of just fighters not spares etc.
read this link below - esp last line of article
Uncle Sam's War-Mart - Special Report - Sunday TOI - Home - The Times of India
This is how prices of aircraft matter over their life time..
Now you can make out how 200mill of Eurofighter and 166 mill for Gripen over lifetime
For India what will matter is Fly-away cost + Support for parts which will not be manufactured in India under TOT + Weapons package . That will decide the final price offered by OEM to Indian gov.
