HARM RUK mode
-
The HARM goes “active” once it is 20 miles from the active STP - even if the STP is behind you. So any threats within a 20 radius of the active STP will, subject to other parameters, be killed.
You can fire it from more than 20 miles but it won’t even start looking until 20 miles from the active STP.It’s realistic but not how most people think it works ��

just create a markpoint towards threat and make it active, the HARM will take it as a steerpoint

Yeah, but do you know how many steps it requires to do so? Not practical in a situation when you are suddenly painted and shot at by a popup threat closeby. Might as well just use HAS mode. But when there are several same type threats in the same vicinity, you might not be able to retaliate the exact threat that is shooting at you.

MARK (whatever number on ICP) -> Slew HUD/FCR -> TMS UP -> TMS UP -> ICP NUM 0
come on, do some multitasking

@Pandacat, switchology reigns supreme

That’s the problem I have with RUK: the fact that it requires a steerpoint defeats its whole purpose as a slapshot towards a popup threat
The purpose of RUK isn’t a quick response to an unplanned emitter. Don’t use a screwdriver to dive a nail. RUK is employed against a pre-planned emitter with large uncertainty in position. PB is designed for maximum range without off axis (won’t fire outside 10 degree window facing). And EOM is for a well known emitter position providing significant off-axis capability.
The F-16’s TOO mode is HAS or HAD and it doesn’t have a self-defense mode like F-18.

Yeah, this is what I am talking about. Gotta use HAS or HAD. Btw, self-defense mode is not modeled in current version of f-18 right?

HAS/HAD mode:
Slew->TMS UP->shootHave fun with the rest of your steps.

You should know that the rest of the steps contains two steps only.
OSB whatever and Pickle.

Interesting. I got my info straight from the 34-1-1
page 172
“Range Unknown (RUK): opportunity/Self-defense mode. The seeker is activated immediately after launch with a 120° FOV. Used when the range is completely unknown in self-defense.”page 178
“RUK is a self-defense mode used when you have a specific threat painting you but have no information on its range.”Anyways, here is a nice visualization of the different profiles:

that does not mean it does not need a steerpoint

That’s cool, I’ll just have to get quicker at creating markpoints

http://i.imgur.com/9xccOsi.jpgThis picture has been the source of much confusion. Many see 3 cones and think this must be the 3 different kinds of POS mode in F-16 (EOM = EOM, PB = PB, TOO=RUK). But it is not necessarily. What name has been given various HARM use in F-4, F-18, F-16, etc. has not been consistent. In certain planes there is a non-turning HARM use where the missile is lofted in a geographic direction and at some time/altitude turns on and looks. It doesn’t go for a waypoint or anything and it was known as “PB” which is distinctly different than the “PB” mode used in F-16 which does seek a geographic location. You see the confusion! F-16 PB mode was probably named because it is kinda sorta similar to F-4 unguided mode but not really. F-18 driver looking at a synthetic Maverick-like view would call this “Target of Opportunity” while F-16 driver will call it “HARM as Sensor” despite being essentially the same.
I wonder what is the origin of this picture. I think it wasn’t F-16 specific and may be some Power Point presentation for a general (pardon pun) audience. BMS isn’t exactly like real F-16 in some ways. Difference between PB and EOM/RUK would be more pronounced.

i remember reading in the book “Viper Pilot” by Dan Hampton that he used the harm in a self defense manner similarly described to original post. i don’t have the book with me at the moment. anyone remember this?
-
It would be stupid not to have MADDOG type mode on a HARM and SEAD platform. Even if the missile is blessed with GPS guidance.

In any case , without any lock the missile needs a point to fly to , wether it is preprogrammed ( we could program a steer point by default 15nm in the nose of the AC) or steer point from AC…
Harm will never perfectly mimic the real anyway since this is sensitive information we don’t want to go further
-
HARM is already quite accurate in BMS.
There are some missing things like SEAD datalink, manual threat input trough DED, tracking indication on HAS screen.
However all of above are described in non classified manuals. -
The seeker head does not go active at launch it goes active 20 miles from the active steer point.
-
even in RUK?
-
Correct - I have tested this.
Place one threat 30 miles from steer point and one, same type, at 10 miles from steer point - launch harm at 40 miles from steer point in RUK - it will over fly the first threat and kill the one 10 miles from steer point. By adjusting the distances I proved the seeker head goes active at 20 miles from steer point
