The three owners are part of the U.S. government, since it purchased or subsidized the aircraft.
As for your question on simulations, I am not going to comment on what a rival company claims to have done in a simulation. I cannot understand how they got access to it. In terms of the simulation the company used, I'm not sure what it used to build its simulation model, since that is not shared. They can announce whatever they like, I cannot contradict them. I don't have access to whatever their claims of success are based on.
All I can say to you is that we and our partners have been analyzing everything there is out there for a number of years. We compare that to the aircraft's capability in a very detailed way. That's why it's modified for adaptability to future conditions.
I cannot tell you whether their claims are true or false because I don't really have access to what they have done, but I can tell you that, on our side, we have been studying that for almost 10 years in great detail and with the help of many experts. This fighter is still the most competitive in a dangerous and integrated environment, as you mentioned.
