Yes the poll times in 30 days.
I want a different name for it, but right now it stands at Semi-Active Radar Homing (SARH, not SARS). Much like the old Anti-air missiles (Sparrow, AA-6) where the pilot had to get a lock and then keep the missile in the line of sight so the missile will "ride" the radar wave from the firing aircraft to its target.
Advantages (in theory):
Faster Reload/Lock time needed because you only need an inital vector and range for the next missile to go to. Then its a matter of guiding it to the target.
Greater Range or Payload (or both). Less guidance equipment means more fuel and/or explosives
Less likely to be affected by countermeasures. You aren't locking on to the countermeasure now are you?
Good for the old-school mods like TVWP or TCs like FS:AAB
Good at longer ranges
Disadvantages:
Can only target one target at a time
Bad at shorter ranges
Bad vs maneuverable targets
Can't evade any incoming fire to any certainty
I don't know how much im gonna have to recode
