I thought the 2000-5 was the most classified than all due to half of it's systems been used in the Rafale. Well,yeah the 2000N variant carries nuclear weapons but the 2000D has only normal A2G weapons and the same radar only with A2G capabilities,i thought it was based on the 2000C which i think they are all based,due to the 2000C being a multirole A2A/A2G. At least we can have the 2000B,its exactly the same as the 2000C only difference it has a bit more fuel storage and the 2nd guy behind manages radar and weapons.
