You're right on the P-51D, I forgot that.
The UH-1H and Mi-8 aren't ED's. They're Belsimtek products.
I don't consider DCS Combined arms a "DCS level product" insofar that it's not a detailed systems focused study of an aircraft (or piece of armor). Also, wasn't CA part of a gov project as well (or at least a bid for one) to train forward observers?
Flaming Cliffs 3 isn't a DCS level product. In name or practice.
Didn't ED actually say a while ago that they were going to be more specific with how the DCS label was applied?
In any event, let me restate:
We haven't seen a DCS level modern combat aircraft developed by ED that wasn't initially developed to fulfill a government contract.
