because of its configuration, the Pantsir missile can not engage target at ranges under 4 km. That's why Pantsir has guns.
Interesting point on the min-range, I'd say they went with the booster on Pantsir because they have guns though rather than guns to fill the engagement hole.
It is almost certain that navalized TOR will be installed on some vessels. Just don't know which ones. My bet is on the Project 22160 patrol ships.
22160 definitely seems like a good prospect for naval Tor, been trying to work out where they could put it.
Previously released art of Naval Tor could fit on foredeck in place of the gun, that could be possible for an AA version of Karakurt, also 22160.
Otherwise the only thing that seems possible without a big superstructure rework is containerised in the module section but that'd need the engagement radar to elevate somehow. Not impossible but a bit awkward & I've seen no sign of any concepts like that.
Over on Balancer forum they've been considering similar question but more on how to fit it on a 11356 to give it a 2nd AA layer
This config seems fairly possible
But the main problem for 11356 is still the engine issue, they could at least as easily put Palash/naval Pantsir if they wanted to.
