Life is never equal. WIWOL Ltg vs Hunter was always a good scrap. Ltg could win above FL250, Hunter below, but mainly a draw providing Ltg remained fast and Hunter turned.
I was foolish enough to fly the T28, thus 2 x T28 vs F14 was fun. If you used USN rules shoot first; ask questions later, then the F14 won. With USAF rules, ident before fire, then the T28 with a gun was even.
Minimum turn performance you would accept when taking the HMD against a 9g adversary? assuming all things equal.
Assuming both aircraft turning with the same radius / turn rate and about the same centre, then isnt the turn rate of the sightline (sightline spin) for the HMS aiming point constant? If so, then for a limiting case of the HMS not being quite on the target, a touch of instantaneous g should help. Then that affects drag, speed, turn, etc, etc, and as I said things are not equal. So a cheap and reliable aircraft with a basic capability to find targets then fire and forget is preferable providing the politicos agree but nothing is equal. A good political decision (USN rules) before any engagement is more valuable than g.
