HARM in POS mode
-
<p>@Mav-jp <br />The AGM-88D Block VI and the AGM-88<strong><u>B</u></strong><strong> Block IIIB (yes, a </strong><strong><em>-B</em></strong><strong>) </strong>did have a GPS/INS (replacement of the standard “mechanical guidance gyros”). The -D was never fielded, but the AGM-88<strong><u>B</u></strong><strong> Block IIIB </strong>was fielded in the late 90s, early 2000’s. The USA never used them, but other countries like Germany and Italy did so, according to some sources.<br /></p>

<p>@Mav-jp but the HARM is the fastest, others come in glide form which takes a while.</p>

<blockquote>BMS simulated AGM-88<strong>C</strong> which does not have GPS capability, hence the requirement for the targeted emitter to be active for the HARM terminal guidance to work.</blockquote><p>does that mean that you still need emission from the source even when in the POS mode?</p>

<blockquote>does that mean that you still need emission from the source even when in the POS mode?</blockquote><p><br />I expect you’ll hit the ground somewhere close to the radar, but you (probably) won’t hit the radar dish.<br /><br />It’s 150 lbs warhead, which sounds like a lot, but I suspect a majority of that is the weight of heavy tunsten fragments, than raw explosive charge. (Compared to eg. GBU-39 SDB, which is 250 lbs and presumably more accurate guidance to a GPS target.)<br /><br />I think the HARM warhead is about spraying large pattern of tungten fragments, which will be coming in at high mach… vs a more conventional explosive or armor-piercing warhead.</p>

<p>@Alfred Yes, you need your SAM target to be emitting for a HARM to hit in <strong><em>any </em></strong>mode.<br /><br /></p>

<p>If we want to implement INS/GPS in our HAMRS we should implement also the Sa20 Sam</p>

<p>@Revientor Bring it on :-)</p>

<p>@Mav-jp Sure, never claimed the contrary. <br />It is perhaps interesting to implement a HARM version compatible with the time frame simulated in BMS. </p>

<p>BMS HARM cannot target GPS coordinates like SDB. I tested it in 4.34 and it didn’t hit when fired at a TGP locked target.</p>

<p>@airtex2019 <br />I agree an all what you have said… and this weapon “works” just as you have supposed to, the main thing is not the weight of the bullets <em>(please let me call them so)</em>, but the speed they are sprayed on the hitting area.<br /><br />With best regards.</p>

<p>This is an interesting topic, and one I am of 2 minds . As someone who is more DEAD then SEAD, there are situations where a HARM with GPS would definitely be nice. However, having our HARM version has made me a better Weasel . Without the “Magic Bullet”, I’ve had to learn other ways to accomplish the mission. In the Hornet I use SLAM a lot. I’ve had to rely more on tactics such as using terrain, etc.</p>

<p>@drtbkj <br />So it is, dear Joe. And here we are, with “the talk”.<br />In my humble opinion, choosing between SEAD and DEAD is only a matter of strategical, more than tactical, decisions.<br />I mean for that: what is more useful for our troops (yeah, it’s always all aimed to them, you know)? Calling for a JTAC (an aspect to be still full implemented in Falcon, as far as I know) or a more generic air support, with TOO and stuff of that same kind? First come first. <br />And the second is: what kind of SAM battalions we have there, first (this may drive to SEAD) or second generation (and this one could drive to DEAD instead)? But, first of all: what do we know about their presence in the area of our interest? And are those informations reliable, and how much? And this may drive to the conclusion: may I have JSTAR or drone (= local, more useful because it’s real time constatly updated) support, if available? And to this conclusion too: the relevance of having a 3D map, and correctly reading and interpreting it when planning sorties.<br />Can you realize now how much work is behind a TE (or a campaign, it’s the same) properly conceived and done, and all the others, and what is the meaning and relevance of a briefing seriously made before taking off?<br />All seen in those Discord discussions of ours, remember? And here they come, eh eh eh. <br /><em>“Learn to think before you shoot”</em><br /><br />With best regards.<br />Gianni.<br /><br /><br /><br /><br /><br /></p>

It is a very cool aspect of BMS that it allows us to “think strategically”, and SEAD has it’s time and place. However, for me it remains more fun to blow things up As the poet said-“If they’re in a million pieces they’re suppressed.”<br /><br /><br /><br /><br /><br /><br /></blockquote><p><br /></p>

<p>@drtbkj <br />Hi, Joe.<br /><br />Blowing up things? It’s my sport too, as you sure remember - and that is just what I am used to do with SAMs <em>(when I am allowed to, of course)</em>. <br />No matter of how many pieces left behind, though, because often I haven’t time to count them, you know. <img src=“/plugins/nodebb-plugin-emoji/emoji/android/1f606.png?v=dsk3o53jm16” alt=“” class=“not-responsive emoji emoji-android emoji–laughing” /> <br /><br />With best regards and to soon,<br /><br />Gianni.<br /></p>

@DUSTOFF17 said in HARM in POS mode:
<p>@Alfred Yes, you need your SAM target to be emitting for a HARM to hit in <strong><em>any </em></strong>mode.<br /><br /></p>
why then the HARM doesn’t miss at all in POS, SD, GS DE mode when the fire radar is not emitting even?

could you please give me a repro case because i can’t reproduce it
easiest way of course is to fire in POS in TE on a Friendly sam
how do you set up your waypoint ?
-
Got a repro case with a precision steerpoint
Fact is that the INS deviation code is acting only after the first detection in case signal is lost but not on the standard flying phase to the steerpoint
thanks for the bug report
