No it's not so much drag, as it is they want it to do everything under the sun, whats next a hot-tub.
LOL
All kidding aside, they where offered sweetheart deals to produce and or modify the F-16s airframe, which at the time of programme conception came closest to the flight profiles and loadouts and size constraints set out.
They wanted and sold the ideal of makeing their own design from scratch to the Europeans by makeing everybody over there think they would make a mint and create jobs in a beliegered industry.
But the fact is the oringional plane was a kick ass interceptor, and would be operational well into the next few decades. But the more multi-roles they added to the multi-role concept .... it started to grow. To the point that current models fully loaded (concept models) do not even out perform the current F-16s.
They have tossed soooooooooo much money into this programme it's a crien shame.
See it's like this .... add a bunch of hardware, dang now we are under powered. No problem we'll make the engines larger, dang now we gotta carry more fuel. Shit now it's way to heavy for the gear, no prob we'll beef them up. Shit now it's to heavy again .... how can we meet the desired flight profile ..... OK even stronger engines again .......
and it just never stops.
Very simular to what happened to the Tornado.
Two engines that where just underpowered, so they had to make two versions ..... history will repeat it's self, and I'd bet money you'll see two versions of this plane two, one small jet can't do everything under the sun, and then be expected to out turn an F-16. At least not the way they make em over there.
Thats all ....
