Low Level Light - IR Ship Flags Working?

The Low Level Light (LLL) flag may be over-reaching with it's detection distance. Is the IR even working?

When I ran the attached test scenario is was nighttime. You'll have to use my homemade database to run the attached test scenario (using EC2003 GIUK Battleset).


1. Play Blue and crank the time compression up to 5 mins. You'll get a detection at 21nm....if it's nighttime (haven't tested during daylight). Both Blue and Red are "Large" height so according to Harpoon paper rules the visual horizon would be 19nm for Large vs Large. Seems LLL might be overreaching by a couple of miles. LLL wasn't part of the original Harpoon paper rules as far as I can tell, so not sure if even the visual horizon of 19nm would be too far for a LLL sighting??? Debate!

2. Open attached database and change the Des Moines' flags. Delete LLL flag and add the IR flag. Save and export database. Re-start scenario as #1 above. Assuming the scenario is during nighttime again, you'll get detection at 7NM. According to Harpoon paper rules I read it as IR sensors should have a 20nm range up to visual horizon. Is the IR flag working?

3. Open attached database and change the Des Moines' flags. Delete IR flag. Save and export database. Re-start scenario as #1 above. Assuming the scenario is during nighttime again, you'll get detection at 7NM. So, with OR without the IR flag you get a 7nm detection. Proof the IR flag doesn't work?

Could be a visual horizon issue, or maybe the LLL and/or IR flags are broken, or all of the above?? And then again I could be broken and I'm just missing something and all works as intended

Interestingly enough, I made a quick scenario using HDS III GIUK Battleset and got a 19nm detection. I have no way to know if the 2 ships I used had the IR and/or LLL flags since I can't open that Battleset's database.
