Ok, two important things:
1) I'll compare tanks from the time the tender for Malaysia: PT-91
MZ and T-90
S.
2) This upper is very important becouse basick PT-91 is better then T-72B only in FCS. But PT-91
MZ (or PT-91
Ex) is better tank then T-90
S with erly turret.
It is obvious that T-90A and AS is better tank (except the engine, transmission, and BMS) then PT-91MZ.
But, as I said - I will write about T-90
S and PT-91
MZ
Again: PT-91 and PT-91
M is one version of the tank (1995-2000), PT-91
MZ or PT-91
Ex is another, deeply modernized version of the tank (2003 -).
The same: T-90
S with erly turret (1992- ~2000), and T-90
SA (~2000 - ) with welded turret. Similar in name but a completely different in capabilities the machines.
FCS:
In T-90S you have old 1A45T Irtysz, with not modern TO1-KO1 (TPN4-49 Buran-PA) or TO1-PO2T (with AGAWA) , PNK-4S. Night vision Buran-PA is ~1200 is in passive mode. AGAWA is much better - it can find a tank with a max. 2500 m, but the range of identification is much much lower.
In PT-91 you have SAVAN-15 Sagem with CITV (VIGY-15) (You haven't CITVit in T-90S...). It's fully computerized FCS.
About SAVAN-15:
http://www.sagem-ds.com/IMG/pdf/D1385E_savan15.pdf Savan 15 FCS – The Drawa FCS is replaced by the French Savan 15 system, built by Sagem Defence Securite. The Savan 15 FCS is derived from a similar system used in the French Army's LeClerc MBT. The system features gun stabilization enabling the tank to fire on the move, increased first round hit probability and the ability to operate at night
. The system consists of day/night gunner's sight, fire-control computer, gun stabilization sensors, lead-angle sensors and interface at the gunner's and commander's stations.
VIGY 15 optronics – also from Sagem, this is a gyro-stabilized panoramic sight for the tank commander. It has hunter-killer function – targets sighted by the TC are signalled to the gunner, or in emergencies, engaged by the TC himself.SIGMA 30 laser gyro – another Sagem product. The system is used for navigation and stabilization of the MBT. 2A46MS 125mm gun – a Slovak-designed weapon, it has a 23% increase in first hit probability as compared with the original Soviet 2A46. Ammunition includes APFSDS, HEAT and HE., and most important: full electrical stabilization EPS-91M fom Sagem
This all solutions is light-years distant from old Irtysz from T-90S with added AGAWA
Amunition.
Well. Basick HEAT and HE-FRAG are the same. But APFSDS - Russian offers what? Of course old BM-42
With PT-91M we offer definitely better IMI ammo (~460mm RHA for 2000m vs. 500-540mm RHA for 2000m).
Engine:
Simple. In T-90S you have old, ugly, fuel mass-eating W-84MS (840HP), or mod. W-92S2 (1000HP)
But mechanical power transmission is the same like in T-72B. And it's suck. It's horrible -like in all T-72 clone...
In PT-92MZ we have S-1000R diesel engine – the original PT-91 are powered by S-12 engine of 850hp. The Malaysian PT-91M has the more powerful S-1000R, rated at 1,000hp. The engine is manufactured by PZL-Wola S.A. The most important is converter power transmission ESM-350-M form SESM Renk. This is a world class. Next: Mechanical Works Diehl tracks – the PT-91M replaces the all-steel tracks with Type 570P track from Diehl Remscheid GmbH which have long service life and low maintenance requirements. It is similar to the ones used in Leopard 2 MBT
Protection.
Basick amrour PT-91MZ is about 500mm RHA vs APFSDS. Propably
in thickest turet part. So it's between late T-72M1 (1988) and T-72B. But: ERAWA-2 ERA tiles – dubbed dynamic armor, these explosive blocks are designed to improve protection from anti-tank projectiles / missiles especially HEAT rounds. Tests by the manufacturer have shown a 50-70% increase in protection against HEAT rounds and a 30-40% increase against AP rounds. The ERAWA system consists of 384 blocks (108 turret, 118 hull and 84 on each side of the anti-cumulative screen@side-skirt) Coverage is much tighter with ERAWA than with Kontact-5. With ERAWA virtually there is no gaps.
Next is polish PCO SSP-1 Obra-3 laser warning system – it's simmilar to the Sthora-1 . It's placed on each quadrant of the MBT, the system gives warning that the tank is being 'painted' by laser – whether rangefinding or targeting. This allows the crew to find the direction of the laser emission and deal with it accordingly.

then rest later - if I find time
