AGM-154A JSOW-A wind-correction does not account for bomblets

[Northstar98]

Hi everyone,

It seems the AGM-154A JSOW-A does not account for the drift of its bomblets when correcting for the wind. The weapon seems to correct to fly itself directly over the target, but the bomblets will encounter drift due to the wind as they fall. In order for the bomblets to actually impact the target, the JSOW should fly such that its flightpath is upwind of the target, so the bomblets drift into it.

With high-enough crosswinds (the track below is tested with a 15 knot perpendicular crosswind at 33 ft), small-enough targets and high-enough function heights (tested with it set to 1000 ft, with an actual functioning height of ~1340 ft AGL) it can lead to a total miss, doing no damage. With 0 wind however, the same target set-up has all targets destroyed.

I am waiting for a 01 GOOD alignment (testing with the F/A-18C).

Interesting, I thought that had been addressed in this patch: https://www.digitalcombatsimulator.com/en/news/changelog/release/2.9.15.9408/

Weapons. AGM-154A wind correction parameters updated.

Maybe the problem is more-so dependent on the amount of wind.

Well, in the track, the JSOW's path has it directly overfly the target - not compensating for the drift of bomblets at all.

Reducing the wind to 10 knots at 33 ft results in a near miss, the track above is with 15 knots.

I thought so too, but it drifts even in light winds.
