- Is the 7.62mm the correct choice for the T-14? Or will we likely see other/additional weapon systems and a different commander sight setup in future production versions of the T-14?
In addition to being less powerful the rifle calibre machine gun {RCMG) lacks the range of heavy calibre machine guns (HMG).
It is less effective against protected targets.
But personally I would go with a mixed mount carrying a PKMT machine gun and a Balkan 40mm automatic grenade launcher... the HE power of the 40mm grenade greatly exceeds the performance of HMG rounds against soft and moderately hard targets with a range advantage too. Against other targets the RCMG has enough power for most targets and more ammo to allow more targets to be engaged.
The problem with 40mm grenades is the volume required for the large ammo and the low velocity can make time to target a little long.
- What type of other weapon system would make sense to be installed on a 4th generation main battle tank (if any). I am talking about current technology, not something that will only be readily available in a decade or so.
I would like to see a 57mm automatic grenade launcher fitted as a backup weapon.
the 57mm gun they have in development (not the high velocity gun for the IFV) has a very heavy shell that would be very powerful against targets that don't require a 125mm HE shell... when they change to 152mm calibre this will be even more important as space for ammo that size will be limited... it makes more sense carrying 60 x 57mm shells than maybe 10 152mm HE shells that would fit in the same space...
Note Isreali tanks carried a 60mm mortar... mostly because they used them for illumination rounds because their night vision stuff wasn't very good but the extra HE power was found to be useful for targets that didn't need 105mm HE shells.
- Do you guys prefer the panoramic sight and RWS to be combined in one unit? Or do you prefer them to be separated* for redundancy or other reasons?
The driver will be focussed on driving and not shooting at anyone, while the gunner needs to focus on the target assigned by the commander. That means the roof mounted machine gun is free to be used by the commander (the gunner aims the whole turret and main gun so they have the coaxial MG anyway.
If the commander is going to be the primary user of the roof mounted MG then it makes sense to slave his optics to it so what he can see he can shoot at straight away.
I would like to see them add a 40mm grenade launcher to that setup...
* In Western designs it makes more sense to separate them, as there is an extra crew member (the loader) that can operate the RWS from his station when not loading rounds like a madman. T-14 hull currently seats only 3 crew members so the RWS would need to operate in automatic mode most of the time, which adds complexity to the FCS. Since we will see T-15's operating besides the the T-14, would the MBT need any additional weapon system in the first place? Which brings us back to question one : is the 7.62mm the overall correct choice for the T-14?
Even if Armata had a human loader I think having the MG under the control of the commander makes more sense.
The commander should be scanning the area for targets and threats... an enemy soldier pokes his head around the corner of a building to fire a rocket and the commander sees that he needs to shoot straight away... a burst of MG fire and the command to reverse the tank to the driver should be as fast as possible... the loader wont have nearly the same level of view as the commander to the time it would take the commander to direct the loader to get up and fire the MG... it would be quicker for him to do it himself.
Worse comes to worse the commander could just monitor what the gun is aiming at in auto mode to find targets and threats himself... in a dug in position the driver could operate the roof mounted MG...
The crew positions in the Armata (and other vehicle families) are supposed to be unified so each crew position can perform any crew role so you can be gunner, commander, driver from any one position.
IMO 7.62 makes a lot of sense, but I think given the experience learned in Syria, it's time to introduce a supplementary heavy RWS in 23mm, 30mm, etc, at least for every 3rd or 4th T-14 to function as a BMPT for each platoon, without wasting hulls on a dedicated BMPT vehicle.
The BMPT concept in the past has been provided by using Shilka vehicles and even trucks with ZU-23-2s on the rear... I think having a few BMPTs in a platoon is worth it.
In fact in situations where the enemy has few or no tanks (ie COIN ops etc) I think a BMPT would actually be more valuable than an actual MBT... most MBTs are optimised to penetrate enemy MBTs which is overkill when the enemy has no or few MBTs.
In comparison a vehicle with a 120mm gun/mortar and a 23mm twin barrel cannon and a 57mm grenade launcher would be an excellent anti personnel/light armour system.
