Could I buy a bunch of T-90XEs?
Like, 2000, if that's not too much cost?
If it's too high then 1000.
If that's too high then 500.
Cost is 5.65 million per unit. You decide.
How much is one SAM-II? Can I help with R&D of the Tungsten products?
Well, normally, they're 1.43 times the cost of a standard SAM, but hardware installment for targeting systems and AI software is required, and that's where the money lies. However, since you are my ally, the price is the same for a normal SAM, and the targeting system is 0.875 times normal price for allies.
Yes, you are welcome to aid Tungsten.
