This would be a pretty fantastic system for Ukraine, as well as other smaller militaries relying on 'technical' type pick up trucks.

APKWS is apparently in the last big tranche of gear from the US to Ukraine.  It's not crystal clear what the launch platform is, but I suspect integration with aircraft is likely to be too time-consuming.  So a ground launcher is quite plausible.  And probably implies that there is a current US user (USSOCOM most likely).

Turns out the Vampire APKWS has been sent to Ukraine:

Interestingly its being billed not as a ground to ground weapon, but as an anti drone system:

I suspect it will kill more ground than air targets.

APKWS continues to be upgraded, now with a multipurpose HEDP warhead.

HEAT APAM Warhead for Hydra Guided Rocket

Watch live fire testing at the Mile High Test Center in Sierra Blanca, TX May 3-5, 2022 for General Dynamics Ordnance and Tactical Systems HEAT APAM Warhead ...

Paired with the earlier shown proximity fuse (or ideally a multi mode programable fuse for proximity, point impact, or point impact delay) this will make for a really versatile little missile. 

The article lists current all in cost of APKWS is $27,500.
