Yes, but the entire point is that other fighter planes have identical requirements but don't have comically out-dated avionics.
Don't guess. Don't make up stories. Don't carry water for incompetent people that are protecting their own backsides.
Compare. Look at what other, more competent people have done, and use that as your benchmark.
That's always the key with these things. You don't have to be an expert. You don't have to have secret knowledge. Other people do. Just look at what they've achieved (or haven't), and compare against that.
When people come up with excuses, you don't have to believe them, even if they're experts in an esoteric, specialist field such as "nuclear-war-resistant stealth fighter design". Even if they're some sort of "authority", so are other people that designed their own stealth fighters.
This is a very useful life skill. Use it!
As a random example, there's countless arguments from "experts" such as economists, politicians, and industry thought leaders about how unaffordable universal government-funded health-care would be in the United States. Meanwhile, dozens of similar countries have done it for decades! Just look at the success of other countries and then dismiss the excuses you hear back at home out of hand because now you know: they're just excuses, not reasons.
