The M1A2C IMO is a great tank. The SEP V2 is a great tank also. Just lack of maintenance and sitting in the motorpool, the tank goes to crap. The V3’s made it easier for crews to do 2 level maintenance in the field while at the same time saving down time of the tank. The V3 also has faster FCS processing along with many other improvements. The CROWS-LP is also a big improvement over the previous version with FCS improvements. The Armor on the Hull and Turret has been redesigned for the lastest modern threats.

What about the engine - is the turbine going to be replaced?

Well the link says: "The M1A2 SEP V3 is motorized with an Honeywell AGT1500 gas turbine engine."

 

So "No", at least as per the current specs.

How good is the CROWS system? I remember the old CWS on the A1 was so touchy in power mode that most TC's used the commander's override to lay the 50 cal in azimuth.  Also good way to knock your loaders head in was to forget or not lock in good the crappy leaver to power after using the manual mode to lay the 50 cal.

In general M1A2C is 1st step in a very major modernization. It focuses both on electronics, new APU, improvements in FCS and also significant, significant improvement in armor protection.

 

Next step will be M1A2D, and here it will be more focused on FCS, CITV will be replaced, GPS will be replaced with new designs that have 3rd gen FLIR, new day color cameras, new laser range finders and laser pointers... yes commander CITV or rather ICITV will have now a day color camera and laser range finder besides 3rd gen FLIR, same for new gunner IGPS.

ECP1A is M1A2C (M1A2SEPv3), and ECP1B is M1A2D (M1A2SEPv4).

So in general, lots and lots of improvements.

As for engine, transmission and also suspension, there is a lot of development work, but nothing is decided yet.

In terms of suspension I guess US Army would be happy to replace torsion bars with hydropneumatic suspension system, that is developed and ready for M1.

In terms of engine and transmission, well the variant with MTU MT883 diesel and Allison 5250MX transmission was designed, integrated and tested but, again replacing engines in the entire fleet is expensive + US Army have other priorities as AGT1500 is simply good enough.

Besides US Army invested a lot of money for Cummins and Achates Power opposed piston two stroke modular diesel engines called ACE (Advanced Combat Engine), ACE is lighter, smaller and overall better performing than MT883. This is because opposed piston two stroke diesels, in general have for example better heat rejection characteristics than V type diesels, opposed piston two stroke diesels also have better power density. They did not get popular because they are difficult to design properly, but currently with CAD, simulations and new materials, it is possible to design a reliable two stroke opposed piston diesel.

The first variant designed is ACE1000 generating 1000HP, it is meant for vehicles in 30-40 metric tons weight. On the grahics you can see how much space ACE1000 engine takes in Bradley IFV engine compartment compared to it's current V type diesel. Now imagine how much less space next in development ACE1500 variant generating 1500HP designed for platforms in 50-70 metric tons weight will take in engine compartment of MBT like Abrams.

lots of interesting and needed upgrades, although im scratching my head that M1A2C wont have newer flir, it will only come with M1A2D another few years down the line and only 3rd generation FLIR at that, when there is already 4th Generation Flir technology.

 

 

I am also sceptical about how much the armor can really be improved without increasing LOS thickness of the turret. There are only so many times you can revise NERA with DU inserts within the current existing Turret Length and expect any significant results. There will simply have to be noticeable LOS increase in turret for it to believable for "significant" armor improvements.

Maybe because new FLIR needs a development cycle, something completely normal in real world of adults...

As for armor, of course it can be upgraded, NERA efficency can be increased by changing reactive layer to more energetic one, with plates made from better steel or different metals with better properties. And who says there is NERA or NxRA left in the armor? What if it's a completely different design?

But yes I am perfectly aware that some people are completely oblivious to such simple truths... but hey Gaijin was incapable to even properly model M1A1 armor considering how realistic they pretend to be. On the other hand not surprising considering that this is not necessary non secret data, but people that know had a good laugh. ;)

Tough it's funny they even ignored fact that M1A1 have improved front hull protection, even tough M1E1 prototype have a weight simulator on hull front, clearly implying armor was improved there.

Of course I know this obvious evidence would be ignored as it's contradicts the narrative of the Russian company the Gaijin is. ;)

So in regard of vehicle protection, SB Pro PE is far closer to the truth, even if it's not intended to be for obvious reasons.

Just my little rant here.

On topic tough, here is a photo of a fresh new batch of M1A2C's in JSMC facility.

Interesting that it seems US Army returns to woodland camouflage pattern as standard.

Ok I noticed something. M1A2C turret had changed, I mean geometry is slightly different at front and armor is thicker.

And now the photos.

Ok, it's confirmed, both turret front and hull front are thicker.

Love how they are carefully avoiding any connotations with the 5TDF and L60 series of opposed piston engines that went before.....

And their reliability issues in the early years.

 

I am also curious as to when the US Army is going to give up calling it the M1A2ABCDEF etc and call it the M1A3.

Opposed piston diesels are better than V type diesels. The problem is you need to design them properly.

As for designation. It's simple, simply it's still M1A2 platform and system, M1A3 most likely will have a new turret, that is being designed by GDLS, it will be a new platform and a new system.
