Without going into too much detail, what you get is:
A first-day F-117-type capability with smaller bombs, but with self-defense...
Subsequently - when you start using pylons - a modernized F-16 with no active EW, towed decoy or provision for same...
Not-very-exciting range (in the B model)...
Very spiffy avionics once all the software is working...
As for timing and cost, look at the track record, always accompanied by promises to do better this time...
You pays your money and you takes your ONLY KIDDING you just pays your money.
