Hi im new to this forum and i found the debate on the BMPT very interesting. I think that in this debate there are two levels or aspects that should be discussed separatedly. From now on i will refer to BMPT concept as Tank Support Fighting Vehicle (TSFV).

Firstly, the theoretical need for such a dedicated vehicle and the economical and logistical cost of it. So far, two armies have recognized the need for a specialized tank support vehicle which are Russia and Israel based on their experiences in Afghanistan, Chechnya, Lebanon and Gaza in asymmetrical type warfare. In that sense a TSFV should provide defense primarily against enemy infantry in the same way a SPAAG provides air defense, i like to think about it as a "bodyguard" for tanks. It has been said that Infantry and their IFVs can fulfill this role very efficiently, which is true (BTW, in the conflicts aforementioned, tanks  suffered casualties when they were in poor and often non existent coordination with infantry), by definition infantry is one of the most multipurpose units for ground warfare.  However, mechanized infantry also has its limitations: in case of an ambush the moment  infantry dismounts they instantly become easier targets to enemy than tanks, in case the infantry doesn't dismount and chooses to fight from within their IFV  they can´t be nowhere near as effective with their weapons and also IFVs have lesser protection levels than tanks. In both  theoretical cases, we would end up with 3-4 tank crewmen, 7-9 infantry dismounts  plus 3 IFV crewmen in danger for a total of  13-16 possible cassualties.  If you replace the IFV with a TSFV you get not only less people involved but also better protected and with superior firepower. From that perspective and for that specific mission, a TSFV makes sense and is preferable over mechanized infantry.  

Fully agree.

Secondly, about the specific BMPT to be adopted for Russian army. In general, i like it but i think that its far from perfect, i´ll make a list of the things i would change and/or improve:
 

- To navigate either urban or mountainous  terrain you need high maneuverability as well to be able to escape ambushes. This means to be able to NEUTRAL TURN and GOOD REVERSE SPEED, which are two things that T-72/90 can´t do. So BMPT should have had a different transmission system to allow this.

If the BMPT’s task is to support T90 squadrons, it’s not a problem. 

It would have been a problem if it was suppose to support a more mobile tank.

- Better stations for bow gunners. I think that having bigger crews is a good idea, 5 pairs of eyes see a much more than 3 provided the have the correct tools and the right crew layout. In this case, the  bow gunners hatches should have have been rotatable (like old school commanders cuppola) and/or the grenade launchers should have been mounted differently on fully rotatable RCWS. I can imagine several simple solutions to this. Currently the bow gunners and grenade launchers in the BMPT are mostly wasted potential. 

The limited travers of AG17 is a point to improve. But the current design offers the best protection and is very affordable.

- At last i would have made a slight modifications to the ATGM mounts: perhaps some sort of hard point mounts (like on the wings of attack helicopters and airplanes) to mount not only ATGMs but also MANPADS, rocket pods, flamethrowers, recoiless guns, etc depending on the mission. This way you can give the vehicle much greater flexibility and utility in any scenario outside its specific purpose of providing defense against enemy infantry using guerrilla type tactics. 

Russian companies are always producing missiles with different warheads. So, it can already provide what you call for. 

 

Manpads are specific.

If you want to improve the AD capability, you must transfert your BMPT to the AD artillery C2. 

 

An other option could be to adopte ISTAR kit to be mounted in place of the Attaka launchers with dedicated operators in place of both bow gunners.

Mixted with classical BMPTs, units can provide both close in fire support and close in EW support.

About the discussion of main armament: I think that 30mm autocannons are currently the best compromise. Firstly you have logistics commonality with the rest of the armored fleet. Secondly, you can fire up to four types of ammunition. Thirdly, you can carry much more ammo than, lets say a 57mm autocannon. Fourth and very important: the 30mm autocannons don´t protrude much from the vehicle which is a VERY important aspect for urban warfare often overlooked, actually one of the reasons the israelis kept the 120mm L44 gun is because it almost doesn´t protrude much from the Merkava and doesnt hinder as much its ability to take sharp corners in dense cities (or traverse its turret to actually use the gun). 

TLDR: I think that the concept behind the BMPT has solid foundations but the actual BMPT to be adopted, while overall good, can be improved a lot.

Yes.

I made a model of the T-34M: Astute viewers will notice that the commander's cupola is wrong - it's supposed to be a T-50 cupola rather than the T-34/85 model I stuck on.  

Development of future Soviet tank in 80-s and was a continuation of works started in 1970-s under designation “Project 101”. Necessity for development was grounded by the development of next generatio

  • Bow gunners are questinable decision in a first place. I guess i can live with 1 such gunner with control of AGS in RCWS in frontal part of BMPT with ~200 degrees arc. But having for example commander equipped with RCWS would make that additional gunner kind of less usefull.

Having one or two gunners is very different. Two men can concentrate on two directions. One man can only have one of them under control.

With an improved AG travers, it can become very interesting because it’s possible to cross both arc of fire. 

 

If you transfert one bow gunner task to the tank commander, you will burden its job. Never forget that, into a troop, one of the tank commander is a troop commander too (even a patrol commander too).

 

Having a 5 men crew is a big advantage.

How I see it:
Based on the same MBT platform that it is supporting, potentially up armoring it.
A super structure with a unmanned turret with a single 30mm gun in the middle and a 7,62mm MG that can elevate up to 75 degrees. On each side is a RCWS, with a 12,7mm HMG and a grande launcher. The right RCWS is integrated with the commanders panoramic sight, while the other RCWS could carry heavier armament. 
The commander has a towed UAV which can be elevated above the vehicle for a Birdseye view of the environment.

On  each side of the turret are mounting racks for ATGMs and similar armaments. It can be elevated above the turret for ambushes and shooting above walls.

I am not sure about the manning though. Only way to get a good traverse out of the extra guns is to mount them up on the turret, or else you risk ripping them off accidentally with the main gun. On top, there is only really two spots to mount the RCWS. And this presents the problem of where to mount the CPS. You could put it at the center-back of the turret, but then it would be blocked by the gun when elevated, and both RCWS's. 

 

For me, the best bet is a driver, gunner, commander and weapons operator. Where the commander mans one RCWS, and the weapons operator mans the other and guides ATGM and operates other equipment like drones.

Having a 5 men crew is a big advantage. 

   5 man crew was dropped during and/or shortly after WW2 and nobody is making any tank or IFV with 5-6-7+ man crew. I guess there were reasons for this and any "advantage" was outweighed by disadvantages. Instead every major AFV developing country designers tried to minimize number of crewmembers inside of single vehicle. Nobody today produce T-35-alikes, other than this BMPT thing.

   Bow gunners are fucking WH40K-level of tank design, good for killing hordes of imaginary aliens, not so useful in real combat.

 

   Having ability to fire in 3 directions doesn't help you to win combat in Urban fights. Just yesterday example from Syria:

Dbe0msuW4AA5qNd.jpg

   During SAA push to Yarmouk camp, Hayat Takhrir Ash-Sham manage to take out several AFVs. After 1st "wave" of AFVs were damaged, SAA commanders sended an assault team to bring back damaged tanks (and probably crews, but no accurate info about them that i know). So this is one of those situations for which BMPT is supposedly was made - support tanks in Urban fights and replace infantry (at least partially) during assault operations.

   As you see those guys are doing suppressive fire, fire in several directions with more serious weapons than 2 fucking AGS (which would have hard time to fire in direction in which BMP-2 main gun is firing, because those 2 AGS are facing front and can't do shit to targets at sides and BMP hull doesn't always face those buildings on the left with frontal armor because it can't drive sideways). Did their firing in several directions in the same time helped them? No.

   HTS "opened" a corridor and ambushed armor in it from sides. SAA crews couldn't fire at enemies effectively because they couldn't fucking see them and figure out where+when to fire exactly. Several tanks lost and plenty of killed soldiers are results of that. BMPT could probably survive that becaue of Relikt ERA, but this is specualtion that can be made about any tank with proper side protection modules installed like T-72B3 UBKh. 

 

   Ability to fire in several directions means nothing in cities if you don't have:

1) ability to detect enemies in your LOS, taking into account that enemies put effort in maksing their movement, positions and so on

2) ability to destroy positions and hit enemies in protected areas\cover 

 

  Puting MORE people in those boxes in urban fights is asking for more casulties per single vehicle, especially because UVZ BMPT have no serious sighting system for AGS gunners and their limited arc, limited firepower, limited capabilities to spot AT infantry in their LOS making them nearly, if not completely, useless. 30 mm autocannons would have hard time to penetrate those houses and do serious damage in deep parts of them, even if bad guys infantry was spotted getting to ambush positions or cover.

  

  And if you really want to use UVZ-made BMPT's AGLs, give those things to infantry! They can put them inside of buildings, between houses, fire them indirectly from safe positions and suppress areas, without driving into direct LOS of enemy infantry and asking for tandem RPG or ATGM. 

 

   Thats are reasons why i think current BMPT is useless and waste of money and time. Should be re-designed with 3 man crew*, smaller vehicle with higher protection of sides, bottom and roof; better sensors and completely 360 degrees observation system with software assistance in spotting targets (and even target tracking/aiming like Boomerang-BM claimed to have); better integration with other units - incl recon units via battlefield managment systems; high-velocity and relatively high penetration cannon/autocannon, airburst munitions. Ability to detect and quickly "service" targets on the level of SPAAGs, being capable of shooting down ATGMs/RPGs, including on considerable range during combat in field. If you need to deal with enemies from several directios - use more vehicles instead, as they also can maneuver and pick better angles, cover and positions, than 1 BMPT trying to find place to keep LOS to several enemy positions while having part of weapons locked into limited arc.

 

   *As "The Chieftain" noted - a platoon of generic "T-72s"/3-man crew tank have 4 vehicles to fight, while a platoon of generic "Abrams"/4-man crew tanks have 3 vehicles to do their job on battlefield, and platoon of T-72s in result have higher firepower. Thats why crews should be made smaller.

      SUBJ: RFP for new battle tank

      1.      Background.
      As part of the War of 2248 against the Perfidious Cascadians, great deficiencies were discovered in the Heavy tank DF-1. As detailed in report [REDACTED], the DF-1 was quite simply no match for the advanced weaponry developed in secret by the Cascadian entity. Likewise, the DF-1 has fared poorly in the fighting against the heretical Mormonhideen, who have developed many improvised weapons capable of defeating the armor on this vehicle, as detailed in report [REDACTED]. The Extended War on the Eastern Front has stalled for want of sufficient survivable firepower to push back the Mormon menace beyond the Colorado River south of the Vegas Crater.
      The design team responsible for the abject failure that was the DF-1 have been liquidated, which however has not solved the deficiencies of the existing vehicle in service. Therefore, a new vehicle is required, to meet the requirements of the People’s Auditory Forces to keep the dream of our lord and prophet alive.


       
      Over the past decade, the following threats have presented themselves:

      A.      The Cascadian M-2239 “Norman” MBT and M-8 light tank

      Despite being approximately the same size, these 2 vehicles seem to share no common components, not even the primary armament! Curiously, it appears that the lone 120mm SPG specimen recovered shares design features with the M-8, despite being made out of steel and not aluminum like the light tank. (based on captured specimens from the battle of Crater Lake, detailed in report [REDACTED]).
      Both tanks are armed with high velocity guns.

      B.      The Cascadian BGM-1A/1B/1C/1D ATGM

      Fitted on a limited number of tank destroyers, several attack helicopters, and (to an extent) man-portable, this missile system is the primary Cascadian anti-armor weapon other than their armored forces. Intelligence suggests that a SACLOS version (BGM-1C) is in LRIP, with rumors of a beam-riding version (BGM-1D) being developed.

      Both warheads penetrate approximately 6 cone diameters.

      C.      Deseret tandem ATR-4 series
      Inspired by the Soviet 60/105mm tandem warhead system from the late 80s, the Mormon nation has manufactured a family of 2”/4” tandem HEAT warheads, launched from expendable short-range tube launchers, dedicated AT RRs, and even used as the payload of the JS-1 MCLOS vehicle/man-portable ATGM.
      Both warheads penetrate approximately 5 cone diameters.

      D.      Cascadian HEDP 90mm rocket
      While not a particularly impressive AT weapon, being of only middling diameter and a single shaped charge, the sheer proliferation of this device has rendered it a major threat to tanks, as well as lighter vehicles. This weapon is available in large numbers in Cascadian infantry squads as “pocket artillery”, and there are reports of captured stocks being used by the Mormonhideen.
      Warhead penetrates approximately 4 cone diameters.

      E.      Deseret 40mm AC/ Cascadian 35mm AC
      These autocannon share broadly similar AP performance, and are considered a likely threat for the foreseeable future, on Deseret armored cars, Cascadian tank destroyers, and likely also future IFVs.

      F.      IEDs

      In light of the known resistance of tanks to standard 10kg anti-tank mines, both the Perfidious Cascadians and the Mormonhideen have taken to burying larger anti-tank A2AD weaponry. The Cascadians have doubled up some mines, and the Mormons have regularly buried AT mines 3, 4, and even 5 deep.

      2.      General guidelines:

      A.      Solicitation outline:
      In light of the differing requirements for the 2 theaters of war in which the new vehicle is expected to operate, proposals in the form of a field-replaceable A-kit/B-kit solution will be accepted.

      B.      Requirements definitions:
      The requirements in each field are given in 3 levels- Threshold, Objective, and Ideal.
      Threshold is the minimum requirement to be met; failure to reach this standard may greatly disadvantage any proposal.

      Objective is the threshold to be aspired to; it reflects the desires of the People’s Auditory Forces Armored Branch, which would prefer to see all of them met. At least 70% must be met, with bonus points for any more beyond that.

      Ideal specifications are the maximum of which the armored forces dare not even dream. Bonus points will be given to any design meeting or exceeding these specifications.

      C.      All proposals must accommodate the average 1.7m high Californian recruit.

      D.      The order of priorities for the DPRC is as follows:

      a.      Vehicle recoverability.

      b.      Continued fightability.

      c.       Crew survival.

      E.      Permissible weights:

      a.      No individual field-level removable or installable component may exceed 5 tons.

      b.      Despite the best efforts of the Agriculture Command, Californian recruits cannot be expected to lift weights in excess of 25 kg at any time.

      c.       Total vehicle weight must remain within MLC 120 all-up for transport.

      F.      Overall dimensions:

      a.      Length- essentially unrestricted.

      b.      Width- 4m transport width.

                                                                    i.     No more than 4 components requiring a crane may be removed to meet this requirement.

                                                                   ii.     Any removed components must be stowable on top of the vehicle.

      c.       Height- The vehicle must not exceed 3.5m in height overall.

      G.     Technology available:

      a.      Armor:
      The following armor materials are in full production and available for use. Use of a non-standard armor material requires permission from a SEA ORG judge.
      Structural materials:

                                                                    i.     RHA/CHA

      Basic steel armor, 250 BHN. The reference for all weapon penetration figures, good impact properties, fully weldable. Available in thicknesses up to 150mm (RHA) or 300mm (CHA).
      Density- 7.8 g/cm^3.

                                                                   ii.     Aluminum 5083

      More expensive to work with than RHA per weight, middling impact properties, low thermal limits. Excellent stiffness.

       Fully weldable. Available in thicknesses up to 100mm.
      Mass efficiency vs RHA of 1 vs CE, 0.9 vs KE.
      Thickness efficiency vs RHA of 0.33 vs CE, 0.3 vs KE.
      Density- 2.7 g/cm^3 (approx. 1/3 of steel).

      For structural integrity, the following guidelines are recommended:

      For light vehicles (less than 40 tons), not less than 25mm RHA/45mm Aluminum base structure

      For heavy vehicles (70 tons and above), not less than 45mm RHA/80mm Aluminum base structure.
      Intermediate values for intermediate vehicles may be chosen as seen fit.
      Non-structural passive materials:

                                                                  iii.     HHA

      Steel, approximately 500 BHN through-hardened. Approximately twice as effective as RHA against KE and HEAT on a per-weight basis. Not weldable, middling shock properties. Available in thicknesses up to 25mm.
      Density- 7.8g/cm^3.

                                                                  iv.     Glass textolite

      Mass efficiency vs RHA of 2.2 vs CE, 1.64 vs KE.

      Thickness efficiency vs RHA of 0.52 vs CE, 0.39 vs KE.
      Density- 1.85 g/cm^3 (approximately ¼ of steel).
      Non-structural.

                                                                   v.     Fused silica

      Mass efficiency vs RHA of 3.5 vs CE, 1 vs KE.

      Thickness efficiency vs RHA of 1 vs CE, 0.28 vs KE.
      Density-2.2g/cm^3 (approximately 1/3.5 of steel).
      Non-structural, requires confinement (being in a metal box) to work.

                                                                  vi.     Fuel

      Mass efficiency vs RHA of 1.3 vs CE, 1 vs KE.

      Thickness efficiency vs RHA of 0.14 vs CE, 0.1 vs KE.

      Density-0.82g/cm^3.

                                                                vii.     Assorted stowage/systems

      Mass efficiency vs RHA- 1 vs CE, 0.8 vs KE.

                                                               viii.     Spaced armor

      Requires a face of at least 25mm LOS vs CE, and at least 50mm LOS vs KE.

      Reduces penetration by a factor of 1.1 vs CE or 1.05 vs KE for every 10 cm air gap.
      Spaced armor rules only apply after any standoff surplus to the requirements of a reactive cassette.

      Reactive armor materials:

                                                                  ix.     ERA-light

      A sandwich of 3mm/3mm/3mm steel-explodium-steel.
      Requires mounting brackets of approximately 10-30% cassette weight.

      Must be spaced at least 3 sandwich thicknesses away from any other armor elements to allow full functionality. 81% coverage (edge effects).

                                                                   x.     ERA-heavy

      A sandwich of 15mm steel/3mm explodium/9mm steel.
      Requires mounting brackets of approximately 10-30% cassette weight.
      Must be spaced at least 3 sandwich thicknesses away from any other armor elements to allow full functionality. 81% coverage (edge effects).

                                                                  xi.     NERA-light

      A sandwich of 6mm steel/6mm rubber/ 6mm steel.
      Requires mounting brackets of approximately 10-30% cassette weight.
      Must be spaced at least 1 sandwich thickness away from any other armor elements to allow full functionality. 95% coverage.

                                                                 xii.     NERA-heavy

      A sandwich of 30mm steel/6m rubber/18mm steel.
      Requires mounting brackets of approximately 10-30% cassette weight.
      Must be spaced at least 1 sandwich thickness away from any other armor elements to allow full functionality. 95% coverage.

      The details of how to calculate armor effectiveness will be detailed in Appendix 1.

      b.      Firepower

                                                                    i.     2A46 equivalent tech- pressure limits, semi-combustible cases, recoil mechanisms and so on are at an equivalent level to that of the USSR in the year 1960.

                                                                   ii.     Limited APFSDS (L:D 15:1)- Spindle sabots or bourelleted sabots, see for example the Soviet BM-20 100mm APFSDS.

                                                                  iii.     Limited tungsten (no more than 100g per shot)

                                                                  iv.     Californian shaped charge technology- 5 CD penetration for high-pressure resistant HEAT, 6 CD for low pressure/ precision formed HEAT.

                                                                   v.     The general issue GPMG for the People’s Auditory Forces is the PKM. The standard HMG is the DShK.

      c.       Mobility

                                                                    i.     Engines tech level:

      1.      MB 838 (830 HP)

      2.      AVDS-1790-5A (908 HP)

      3.      Kharkov 5TD (600 HP)

                                                                   ii.     Power density should be based on the above engines. Dimensions are available online, pay attention to cooling of 1 and 3 (water cooled).

                                                                  iii.     Power output broadly scales with volume, as does weight. Trying to extract more power from the same size may come at the cost of reliability (and in the case of the 5TD, it isn’t all that reliable in the first place).

                                                                  iv.     There is nothing inherently wrong with opposed piston or 2-stroke engines if done right.

      d.      Electronics

                                                                    i.     LRFs- unavailable

                                                                   ii.     Thermals-unavailable

                                                                  iii.     I^2- limited

      3.      Operational Requirements.

      The requirements are detailed in the appended spreadsheet.

      4.      Submission protocols.

      Submission protocols and methods will be established in a follow-on post, nearer to the relevant time.

      Shortly after Jeeps_Guns_Tanks started his substantial foray into documenting the development and variants of the M4, I joked on teamspeak with Wargaming's The_Warhawk that the next thing he ought to do was a similar post on the T-72.
       
      Haha.  I joke.  I am funny man.
       
      The production history of the T-72 is enormously complicated.  Tens of thousands were produced; it is probably the fourth most produced tank ever after the T-54/55, T-34 and M4 sherman.
       
      For being such an ubiquitous vehicle, it's frustrating to find information in English-language sources on the T-72.  Part of this is residual bad information from the Cold War era when all NATO had to go on were blurry photos from May Day parades:
       

       
      As with Soviet aircraft, NATO could only assign designations to obviously externally different versions of the vehicle.  However, they were not necessarily aware of internal changes, nor were they aware which changes were post-production modifications and which ones were new factory variants of the vehicle.  The NATO designations do not, therefore, necessarily line up with the Soviet designations.  Between different models of T-72 there are large differences in armor protection and fire control systems.  This is why anyone arguing T-72 vs. X has completely missed the point; you need to specify which variant of T-72.  There are large differences between them!
       
      Another issue, and one which remains contentious to this day, is the relation between the T-64, T-72 and T-80 in the Soviet Army lineup.  This article helps explain the political wrangling which led to the logistically bizarre situation of three very similar tanks being in frontline service simultaneously, but the article is extremely biased as it comes from a high-ranking member of the Ural plant that designed and built the T-72.  Soviet tank experts still disagree on this; read this if you have some popcorn handy.  Talking points from the Kharkov side seem to be that T-64 was a more refined, advanced design and that T-72 was cheap filler, while Ural fans tend to hold that T-64 was an unreliable mechanical prima donna and T-72 a mechanically sound, mass-producible design.
       
      So, if anyone would like to help make sense of this vehicle, feel free to post away.  I am particularly interested in:
       
      -What armor arrays the different T-72 variants use.  Diagrams, dates of introduction, and whether the array is factory-produced or a field upgrade of existing armor are pertinent questions.
       
      -Details of the fire control system.  One of the Kharkov talking points is that for most of the time in service, T-64 had a more advanced fire control system than contemporary T-72 variants.  Is this true?  What were the various fire control systems in the T-64 and T-72, and what were there dates of introduction?  I am particularly curious when Soviet tanks got gun-follows-sight FCS.
       
      -Export variants and variants produced outside the Soviet Union.  How do they stack up?  Exactly what variant(s) of T-72 were the Iraqis using in 1991?

      -WTF is up with the T-72's transmission?  How does it steer and why is its reverse speed so pathetically low?

      Hello, my friends and Kharkovites, take a sit and be ready for your brains to start to work - we are going to tell you a terrible secret of how to tell apart Soviet tanks that actually works like GLORIOUS T-80 and The Mighty T-72 from Kharkovites attempt to make a tank - the T-64. Many of capitalists Westerners have hard time understanding what tank is in front of them, even when they know smart words like "Kontakt-5" ERA. Ignoramus westerners!
       
       
         Because you are all were raised in several hundreds years old capitalism system all of you are blind consumer dummies, that need big noisy labels and shiny colorful things to be attached to product X to be sold to your ignorant heads and wallets, thats why we will need to start with basics. BASICS, DA? First - how to identify to which tank "family" particular MBT belongs to - to T-64 tree, or T-72 line, or Superior T-80 development project, vehicles that don't have big APPLE logo on them for you to understand what is in front of you. And how you can do it in your home without access to your local commie tank nerd? 
       
       
         Easy! Use this Putin approved guide "How to tell appart different families of Soviet and Russian tanks from each other using simple and easy to spot external features in 4 steps: a guide for ignorant western journalists and chairborn generals to not suck in their in-depth discussions on the Internet".
       
       
       
      Chapter 1: Where to look, what to see.
       
      T-64 - The Ugly Kharkovite tank that doesn't work 
       
         We will begin with T-64, a Kharkovite attempt to make a tank, which was so successful that Ural started to work on their replacement for T-64 known as T-72. Forget about different models of T-64, let's see what is similar between all of them.
       
       
       

       
       
         
       
       
      T-72 - the Mighty weapon of Workers and Peasants to smash westerners
       
         Unlike tank look-alike, made by Kharkovites mad mans, T-72 is true combat tank to fight with forces of evil like radical moderate barbarians and westerners. Thats why we need to learn how identify it from T-64 and you should remember it's frightening lines!
       

       
       
       
      The GLORIOUS T-80 - a Weapon to Destroy and Conquer bourgeois countries and shatter westerners army
       
         And now we are looking at the Pride of Party and Soviet army, a true tank to spearhead attacks on decadent westerners, a tank that will destroy countries by sucking their military budgets and dispersing their armies in vortex of air, left from high-speed charge by the GLORIOUS T-80!
