Also, it doesn't take into account the fact that UAV control channels can be jammed by the enemy, rendering the UAV useless and sitting ducks to the slower, fatter aircraft with the meatbag in the seat.

Falcon 9 and Falcon 9 Heavy both use a single Merlin Vacuum engine for second stage, which burns LOX/RP-1.
Raptor is a rocket engine design concept, which would burn, as you noted, LOX/LH2. LOX/LH2 has a much greater impulse than LOX/RP-1, meaning it can lift more weight, but it is also much, much, much more unstable, cannot be stored at room temp, and is much more expensive.
Falcon 9/9H will both be pure LOX/RP-1 for first and second stage, with an option if a customer needed a bit more boost to swap the second stage for a LOX/LH2 stage (with associated greater risk)
Same way fighters found each other in WWII. Line of sight, "Tally" and so forth. At closer ranges, and with active scanned radar's hot, you should be able to get a return off of a contact...at the very least get enough of a heat return to fire a sidewinder. Push to shove, you could always switch to guns and duel, ala, vietnam (Phantoms vs Migs).
This is assuming that passive radar returns are too weak at medium/long range to between the two stealth aircraft (on both sides) to allow a positive lockon for AMRAAM engagement.
