Here’s what an actual battle test platform looks like:

The Russian Air Force has demonstrated high confidence in the Su-57’s stealth capabilities, and has deployed the fighters for high intensity combat operations to parts of the Ukrainian theatre with particularly high concentrations of Ukrainian air defences.

The Su-57 program has prioritised reducing maintenance needs and operational costs to avoid the very low availability rates that have plagued America’s F-117, F-22 and F-35 stealth fighter fleets. One notable means by which this had been achieved is through reduced reliance on radar absorbent coatings, which was achieved by using innovative solutions such as radar absorbent fibreglass. In contrast to American stealth fighters which consistently cost far more to operate than their fourth generation predecessors, this approach allows the Su-57 to potentially achieve lower operational costs than its direct predecessor the Soviet Su-27, thus allowing Russia to move its fleet into the fifth generation without either significantly raising sustainment funding or contracting the number of fighters in service.

You’ve displayed your lack of insight into each and every aspect enough as it is.

And addressing your childish game of name calling isn’t an ad hominem attack.

I see you don’t know what ad hominem means. Ad hominem isn’t a personal attack, it’s a way to deflect from the point being made. You’re trying to discredit what I’m saying by claiming that I don’t know what I’m talking about. You’re not providing counter points, but instead attacking me to deflect because at the end of the day you’rej ust a troll.

In any case, I’ve said all I needed to say here. You can keep on bleating if you like though. Bye.
