SLAM-ER confusion -- bug, or User Error?

[FourSpeed]

Hi Guys,

Started dabbling with the SLAM-ER the past week or so, and, afaict, a number of it's features appear to not work.

First, I'm not talking about datalink, steering, waypoints, or anything that far along the learning curve as yet.  Basically, I'm just treating them as longer range JSOWs -- ie. PP Mode, Set fusing, Set flight profile, Enter precise co-ords for the target points, and call it a day....

What I am observing:

1.  Data Entry works exactly the same as it does for PrePlan JSOWs (Great!) with the additional option(s) of terminal guidance (for me, Drop Angle is all I want). Employing them is identical to PP JSOWs, but at much greater range (Perfect!).

2. Unfortunately, using High Flight mode (> FL350), and launching within  100 nm, I find:

    A> TERM - ANG, quite simply doesn't work/matter at all -- the PTH angle (on F6 View) *always* shows ~25 PTH (+/- a bit for range) - never what I enter using the UFC.

   B>  ELEV - also does not seem to work/matter... Whatever the map elevation is at the tgt co-ords is *always* what appears to be used, regardless of what you enter.   A little more here....

          --- Target: Some Precise LAT/LNG (that works fine - it always gets there and reaches the target if in range). Set ELEV at any number (I tested up to 2000 ft for a 16 ft TGT), and all missiles hit the same ~spot  (TERM-ANG doesn't matter either - I tested 45-85 deg, and they still hit the same ~spot with a ~25 PTH angle) 

 That said, that still works fine for a bunch of trucks on the ground, or a building on land, BUT, if you're trying to hit an oil platform above the sea level, (note: map height is negative at sea on Caucasus map, at least), missiles will often miss by flying into the sea *under* the oil platform, doing virtually no damage. Unless you're lucky enough to hit a  platform crossmember on the ~25 deg attack path, there's no joy for hitting that target, regardless of TERM:ANG or ELEV (FEET) settings you use.

So, are these parameters simply not working, or am I completely missing something here? If these are known issues, then, good to know, I'll bide my time with these missiles pending a fix. If not, I've provided the test mission I'm using, and can make some tracks, if necessary, to illustrate what I'm seeing, but what I'm observing distinctly limits SLAM-ER use cases, compared to a standard Unity Broach JSOW, which works fine, albeit at closer range... 

Any insight you could provide would be most welcome and appreciated.

 

Thanks, and Regards.

The only insight I can give you is that it's still unfinished and partially borked.

If I didn’t miss news about its completion, TERM guidance settings for JSOW and JDAM is still not implemented/completed.  Sounds about right that it would then also apply to the SLAM/SLAM-ER.
