Although anti tank guns in west are largely phased out and look at as obsolete, Syria and other conflicts have shown us in a long drawn conflict that anti tank guns along with other older systems have proven useful. On anti tank guns they have proven useful at taking out stationary vehicles/armour as well as buildings bunkers etc, there cheap ammo, cheap systems, ease of use, and reliability is there key strengths and against armour still pack a punch and capable of taking out older vehicles and modern IFV. of course even within anti tank guns there are different types of systems, for instance the two mentioned above are different in that one is man portable and the other isnt.
As for the replacement for SPG-9 with mention of it been floating around this last year. This has likely been due to the use of SPG-9 use in Syria that has prompted Russia to seek such a newer system. I would imagine the newer system will be lighter, more accurate/better sights and with a variety of new rounds including thermobaric, and with greater likely effective range out to 1.5-2km would be ideal. The current system seems alittle lacking in areas i mentioned on improvement. Of course they could also go down the route of having a recoiless rifle system like carl gustav which has seem wide spread use and proven to be useful, although i think its likely they will focus on a SPG-9 type system as Russia has a large variety of shoulder launched systems which largely cover the range of CG system. So if anyone has any information regarding the new SPG-9 replacement or and ideas please share.
Now onto the T-12/MT-12. according to various sources they put the number of systems in Russian service from 350-500. Now when i was in the forces a many conversations were had on Russian equipment within the area i worked. And many had the opinion that anti tank system of this type was very largely outdated and had no real use since ATGW came along. Now a few people including an USA Major who was there at the time even questioned why Russia still used them as it was believed that they were now being used as artillery systems although there range wasnt great. And with Russia having 1,000's of D-30 in storage why didnt they replace them with D-30? as D-30 still offers limited anti armour capability. Some said it was down to cost to overhaul and train almost 500 systems wasn't worth the cost Vs benefit, and also that the T-12/MT-12 were largely used by conscripts they were unlikely to be deployed in any future conflict and also the training element, some also mentioned another reason that there was an abundance of 100mm ammo sitting around so it made sense to continue to use the system, and course the system also received some simple upgrades to make it a little better.
What ever the real reason what we know was that there still in service in fairly large quantity and that the Sprut-B didnt replace it. In fact the small number of sprut-B in service was likely down to them testing the gun itself and in the role of replacing T-12/MT-12 and the decision wasnt favourable to produce it. And that also could have is reasons. Even though the sprut has much better firepower it lacked the versatility of the T-12/MT-12 in that it cant be used as artillery and that it was much more heavier, T-12 is 2,750kg Vs the sprut at 6,800kg at difference of 4,050kg which is quite a lot and this could impact on means of transport including underslung on a helicopter including ammo also the fact that it was likely much more expensive.
So what could Russia replace the T-12/MT-12 with??????????????
Well this largely comes down to what role they actually want and how much money they want to invest in a replacement, my guess is that they wont want to spend a fortune. So if they intend to replace it with a artillery system then they could easily replace it with D-30 (still having some anti armour ability), or 2S1, 2S3 if they want a self propelled function.So options for artillery could include:
(self propelled artillery)
2S12 sani 120mm mortar
(self propelled mortar)
2S23 nona (BTR80)
2S34 Hosta (2S1/MT-LB)
If they want to have a role of Anti armour/anti tank then theres multiple options. Do they replace with ATGW systems or tanks? options include:
2S25M sprut SDM-1
(ATGW self propelled)
various other vehicles mounted with Kornet/Konkurs
And then they could choose something a bit different and replace the units with systems such as TOS-1 or BMPT. Or we may find that when Typhoon series and zauralets-D gets an artillery system which believe they are planning on they use these units.
or they could design a new system combining a variety of roles. Which i think would be better and wouldnt cost much. Although i would suggest that some are towed and some self propelled on various platforms. My personal opinion is that if they produced a system similar to the Nona-K. a system that can fire mortars, artillery shells, but with the addition of anti armour rounds and ATGW system, while keeping the system light.
i think they have two options. one they could use the 2A70 100mm gun from the BMP-3 which already has anti armour and ATGW systems but would need mortar and artillery rounds designed for it. And obviously mount it a suitable towed mount. Although i see this as an option i think my second option (below) would be better.
My second option would based around a 120mm calibre system. For numerous being that the 120mm calibre looks likely to be around for a long time, and on future systems. In addition to this they already have a similar system the Nona-K which can fire mortar and artillery rounds. So they could use this as a base model design. Also they already have a variety of rounds for 120mm mortars and 122mm artillery systems such as guided ammo. So this has an advantage over having to redesign a 100mm rounds of the same type (guided) for option one. So all they really need to do really is design a 120mm anti armour rounds, thermobaric rounds, etc. and this shouldnt be too hard they could use similar design as either the 2a70 100mm (bmp-3) gun or 125mm current tank rounds and either make bigger or reduce in size. As for the ATGW they could still use the Bastion round and use the same method they used on using Bastion missiles on the T-62 115mm gun using guiding rings or use a reduced size svir/refleks, or design a new missile although i think the Bastion option with guiding rings would be fine, to save on cost. I also believe they could make the system lighter than MT-12 probably around 1000kg lighter you would looking at having something similar in weight to nona-k (1,200kg). And if they design it on a mount which can then either be put onto a towed mount, or a vehicle chassis such as typhoon, MT-LB, BMP, BMD, BTR, T-55/62/72 etc this would not only give it a universal use for various units but also an attractive option for export to other countries for example if you can have it mounted in a simple turret design it could replace the turret of T-55 improving firepower of existing T-55 for poorer nations and the system would cover various roles Mortar, artillery, Anti armour/anti tank including ATGW system all on the one platform i actually think it would see fairly good export potential success, and the fact you could mount it on various vehicles would also expand export potential. The towed mount could be useful as being air dropped in hard to access areas, and yet again this would allow from one weapon system a multi role system, in hard to reach areas there might not be loads of room to have multiple systems also it means your only delivering one system by air and not multiple systems, you would have to deliver various types of ammo for the system based on what you faced. The system could also have a remote control system allowing the gunner to be some distance away from the system if the situation called for it.
so whats peoples views/opinions etc.
On another similar note which was briefly mentioned between me and GarryB on another thread of having a towed mount which could mount anything a 14.5mm gun, 30mm gun, 57mm gun, AGS, automatic 82mm mortar, strelets, SA-13, multi ATGW (kornet D type system), new rocket pods system, Hermes missile, ZAK-57 Derivatsiya-PVO 57mm AD system and maybe a pantsir type system or Sosna-R system or a combination of mentioned weapons for the use of hard to reach places or being mounted on various vehicles including export customers vehicles. Although i see these as two separate systems but similar in design and think both would have great export potential.
yet again any thoughts, ideas, opinions would be great. thanks for reading.
