@Frederf:
I believe this is because the HARM loft profile is dependent on range to steerpoint and so close to steer = little loft. Little loft = threat in seeker FOV and acquisition. I was successful in having an acquisition of a treat emitter in RUK with a steerpoint well beyond the target but only because I was at a low altitude and it didn’t loft too far above the close threat. I estimate that because the HARM turns like a pig that you could shoot a RUK with a steerpoint 90deg left/right and it would find an emitter dead ahead before it was able to change azimuth significantly. If the loft could be disabled or countered I bet RUK could be a very workable “HARM maddog” no matter where the steerpoint is located.
I think it’s only based on STPT range. It’s some where between 30nm and 60nm that decides that the HARM loft to the STPT or goes active.
In r/l LOR I think the RWR hands off a vector (and maybe a target type) to the HARM and set the seeker in RUK mode. Then makes hard turn into the vector. <shrug>We only have bits of info on the subject.
I kind of think that PB, RUK, EOM are missile seeker modes.
POS uses PB, EOM, RUK
HAD uses??? switch to EOM if the seeker drops lock.
LOR uses RUK
HAD uses all, depending on how the target was acquired.
thanks for the info. is it safe to assume there is no self-defense type of mode implemented in BMS?
If STPT were place every 30nm RUK could be used as LOR. Just beware of the off-bore shot. The SAM will win the race. Not a great workaround <shrug>However, the SAM are not nasty enough in BMS to need a SP mode. imo</shrug></shrug>
