An issue might be war time production if for example UVZ's T-15 is chosen over the Kurganetz 25 produced by by Kurganmashzavod.
Well no, existing tank divisions are not all going to get the T-90s replaced with T-14s and their BMP-3s are not all going to be replaced with T-15 and their BTR-82s are not all going to be replaced by K-?? Boomerang troop transports with 30mm Epocha turrets.
A tank division will have all of one type of vehicle eventually so an Armata division will have T-14s, which means it will need T-16 recovery vehicles to pull the weight of Armata vehicle chassis, and the BMP in an Armata division will be the T-15, but all the other vehicles will be Armata based eventually too.
The Kurganets will have its own divisions where the tank will be a Kurganets vehicle chassis with a T-14 turret mounted on it, and its designation will be B-??, and it will operate with BMPs and BTRs based on the Kurganets chassis so all the vehicles in the division will be Kurganets based.
The Boomerang divisions will be the same as will the Typhoon divisions and DT-30 vehicle divisions.
A tank will be developed... in this case the T-14 and its turret and systems will be fitted to all the different vehicle types to create tank or gun platform vehicles for all the different divisions.
The idea is that the logistics tail for an Armata division or a Boomerang division or a Typhoon or Kurganets or DT-30 division will be shorter because there is only one engine type and one transmission type and one type of wheel and one type of track for the three tracked types etc etc.
It also means all the vehicles will have a similar level of protection and mobility so everything should be able to keep up.
It also means Armata divisions are going to be heavy and expensive, while with APS systems and all the other NERA and equipment even a Boomerang and Kurganets type vehicle will still be well protected but will have better mobility.
Saying a Kurganets lacks the protection of a T-90 is true, but the vast majority of the vehicles in a current division would have rather less armour than the Kurganets standard vehicle and with modern APS and other special features it will still be a very good tank.
It seems that for the moment, the T-90M is like the original T-72 in this respect: a "mobilization tank" that can be built in larger numbers and more quickly than a more complex tank which back in the T-72's day was the T-64 and today is the T-14. I would argue the T-72 was a better tank than the T-64. Few here would disagree with the status of the T-14 being better than the T-90M.
The T-64 and T-80 weren't perfect tanks and had some problems, while the T-72 was the cheap mass production tank with good armour and a good gun and good mobility because it was not super heavy. The T-64 and T-80 were the best they could make them at the time, they were the expensive tanks with experimental features, some of which were applied to the simpler cheaper T-72 when they became affordable.
The first T-72s had an optical rangefinder, but got laser rangefinders soon enough as they became less exotic and more affordable.
Right now the upgraded T-72s are the bargain basement option, while the T-90 is a T-72 upgraded as far as possible without a complete redesign, while T-14 is a redesign to fix the basic problems and improve as much as possible everything they can improve.
It will be a decade or more before Armata divisions and Boomerang divisions etc etc are fully equipped and operational, and I think Kurganets based T-14s will be the mass produced lighter tank they will build while the T-14 will be for urban warfare and heavy fighting against a well equipped peer enemy once they get them into service in useful numbers.
The T-14 will coordinate with artillery and airpower in a way that makes all three much more effective... but the Kurganets and Boomerang and Typhoon and DT-30 families will be just as integrated eventually.
Today T90M is top of the line tank as it was T64 and T80s in soviet era...
The T-90AM is the best they could make it without a complete redesign. The T-72 is upgraded with new stuff as it becomes affordable, so the T-64 and then the T-80 and now the T-90AM are their best tanks but not cheap and not mass producible. The T-72 is good enough but over the years has been upgraded with new bits as they become affordable and is superior to previous generations of tanks whether they are T-54/55 or T-62.
T-14 is the best, and is designed from scratch, and the Kurganets and Boomerang and Typhoon and DT-30 models will be the cheaper mass produced versions, but they will likely continue to use upgraded T-72s and then T-90s while they have them in production.
The vast range of other family vehicles based on BMPs and BTRs and older MBT types will continue to be used and many could be converted to robot use as well moving forward... but the core plan seems to be vehicle family divisions for specific roles in specific places.
Wheeled vehicles offer good mobility where the road networks are good, but then they do have cross country ability too and can work together to overcome soft ground.
Or use Heavy Flamethrowers..
I don't think any minefield can survive a full volley of thermobaric bomberdment by Buratino
No matter what they use they will still use mine plows and mine rollers because nothing will remove every single mine from a field... except painstakingly clearing it by hand.
I should have clarified: IMHO, T-72 better in terms of cost-benefit analysis: value for money-time.
Without the T-72 their numbers tank would be the T-54/55 and slightly better T-62, so the T-72 might not be the best tank in the world or in the Russian military, but it certainly does the job it was intended to do which was replace the enormous number of older tanks in the role of main battle tank.
Not only that but it meant the Soviets and Russians could keep their tank numbers up, which was easy with the T-54/55 but would be impossible with T-64 and T-80 and T-90 only.
By combining Buartino's slavo with other mine-clearing methods, Russian forces could swiftly eliminate the majority of mine and IED threats on the battlefield.
By combining different solutions you always get a better result, but no solution or combination of solutions will be 100% effective all the time.
If needed the VKs can drop some FAB-3000´s.
When they run out of FAB-5000s... and FAB-9000s.
FOABs would just be excessive though... just showing off.
