The original NG was going to have fuel capacity of ~2.8T (no idea what fuel density).
The current NG is slated for a fuel capacity of 3.4T (again, no idea what fuel density, but we can probably assume Saab are consistent with it)
The NG that was being marketed to the Dutch in 2009 had an internal fuel capacity quoted as ~3.3 tonnes (7300 lbs). And yet the empty weight being quoted was 7136 kgs (15700 lbs)..and now the internal fuel is nearly the same, but the empty weight has climbed to 8000 kgs.
So its clear that what was the original design goal, could not be achieved for the Gripen E. It’s not lying, but really, you cannot defend it as being just a nominal growth thanks to increased internal fuel. That is clearly not the case. Most likely during actual detail design, they found that the target empty weight was way too optimistic for accomodating the additional payload and fuel weight.
But any customer who would have signed on to the Gripen E looking at the specs being quoted back then, would’ve been sorely disappointed to find the empty weight ~1000 kgs higher than was promised and with its resultant payload decrease for the same fuel-fraction.
