DCS World - Stream Highlight - F4e Phantom - Shrike WRCS mode

Hi there folks ! Here is a short video from my stream highlighting the use of Agm45 Shrike in the WRCS mode. Broadcasted live on Twitch -- Watch live at / shiftiemover

Nice video! Can you also explain how to select the correct seeker during rearming phase? Thank you!

Shrike WRCS mode isn't fully implemented yet ;)

[@shiftiemover4110]

I know this :) but wanted to try it, as guess what , it is the most commonly used method according to the user guide we get with the module.

What I don’t get about WRCS mode is… how can the Shrike actually know the range? You’re not entering a range in the WRCS, just the altitude, so how does it know?

[@shiftiemover4110]

Seeker sees target radar and computer compares to nav computer and selected waypoint , then uses slant range to calculate I think ?

[@ghostdog688]

Trick is that the shrike doesn’t know the range. The WRCS is telling us when to release based on range to the coordinates in the selected steerpoint.
After that, the Shrike flies like a rocket blind at the target unless it emits a signal the shrike can detect. Once that happens, it goes for that signal until the signal stops or it hits something.
If it helps, think of the WRCS as an artillery computer. You tell it how far away the target is and what altitude it is at, the plane will tell the WRCS how high/fast it is, and the WRCS will take that and feed in a pitch, roll and yaw angle to fly and release at the required range based on the weapon mode (Laydown, Loft, AGM-45, DT, etc…)

@@shiftiemover4110 I’d feel safe betting that the Shrike isn’t good enough to provide a sufficiently accurate angle for that.
Did you have the position as a selected waypoint? @ghostdog below says it’s based on that, and I just tested firing against a target without using a waypoint on it and didn’t get launch cues until I indeed placed a waypoint on it, so he might be on to something.

[@mumblerinc.6660]

@@ghostdog688 that seems to be the way it works (I can’t say the manual explains it too well right now), since I couldn’t even get launch authorisation without a waypoint on the target.
Not as though it came close to hitting though, think I fired upwards of 20 Shrikes before even just a few came close with one hitting.
