Kitolov-2 is SALH guided, and can be fired in a top-attack profile. It has something like 12km of range. For the anti armor roll it's excellent, and for the anti-ATGM team roll... it's a 120mm mortar.
True but still worse than Kornet. BTW korent´s range is 10km in upgraded version.
Only with the thermobaric version, HEAT it's 8km, which is still nothing to scoff at. However, it will only have 4-8 rounds depending on the configuration choice they make. The effective range of the 57 is probably around 6km, which is good enough for most tasks, and with guided rounds roughly twice that. Obviously 57/kornet is a good combination. Were it lacks is cost-efficiency, and material destruction. Kornets, while cheap for an ATGM, are more expensive than a 120mm HE mortar bomb, and you can't carry as many of them. If you're attacking a large structure, lobbing a few 120mm rounds will clear it. To use Kornets, $20,000 and half, if not all your thermobaric load. The 57 can pick up a lot of the slack, but it still isn't going to match the efficiency of the 120mm.
Admittedly, my current opinion is that the 57/kornet is probably the better choice for a BMPT. It's a tank support vehicle, and as such, should be with MBT's most of the time. For the most part, the aforementioned disadvantages can be supplemented by an MBT's 125mm gun. War is a team sport.
However, if it was up to me I'd just scrap the BMPT roll. Instead, develop a heavy RWS that replaces the entire bustle and 7.62mm RWS on the T-14, give it a GSh-23 or GSh-30-2 plus a 7.62 coaxial, and put it on every third T-14.
Yes but effective range of 120mm is also less them max listed as 13-4km. Sure potential of 57mm round has worse parameters than 120mmm buuut: can be also guided/programmable and 57mm can provide goods level of AA protection not to mention mucho more rounds carried. 57mm might be also cheaper then 120mm if i am correct.
As for armata variant - the one presented as green little mockup had secondary armament 30mm gun and 4 barrel Gatling ... the only one in Russia so far was Yakushev-Borzov YakB-12.7mm. Interesting if this concept will be followed up.
