Yes, really the question I was asking - pretty sure it is "contracted" for Australia too - is it in service anywhere?

To my knowledge, not in active service yet anywhere.

The more cynical amongst us would say that means it's still vaporware.

Damian's wet dream come true if this actually happens: https://www.defensenews.com/global/europe/2021/07/09/poland-could-purchase-m1-abrams-tanks-from-us/


It's probably worse news for Hyundai Rotem than KMW, though, since a significant contract like this one would have given the former an important foothold in the European tank market.

With the Polish buy of SEPv3 I realized I had not been keeping up with Abrams upgrades.




The Army Contracting Command-Aberdeen Proving Ground (ACC-APG) Belvoir is conducting market research on behalf of the US Army Product Manager Ground Sensors, in accordance with Federal Acquisition Regulation (FAR) Part 10. The purpose of this Market Research is to identify potential sources that have the skills, experience, knowledge, and capabilities required to manufacture and deliver Third Generation Forward Looking Infrared (3GEN FLIR) B-Kits under Low Rate Initial Production (LRIP) and Full Rate Production (FRP) contracts.� The 3GEN FLIR program is currently in the Engineering and Manufacturing Development (EMD) Phase of the Acquisition Life Cycle.� Upon the completion of the EMD Phase and entrance into the Production and Deployment Phase, the US Army plans to award an LRIP contract for 3GEN FLIR B-Kits.� The purpose of the LRIP contract is to establish an initial production base for 3GEN FLIR B-Kits and permit an orderly increase in the production rates leading to FRP. During LRIP, the US Army plans to procure approximately 400 3GEN FLIR B-Kits over a 2 year period.� Upon completion of Operational Test and Evaluation, the US Army plans to procure over 9,000 B-Kits during FRP.����� � The 3GEN FLIR B-Kit comprises a set of common assemblies, including the Dewar Cooler Bench (DCB) (provided as Government Furnished Property (GFP), optics (afocal, imager), and circuit card assemblies (CCAs). The B-Kit optics collect radiation in the Mid-Wave (MW) and Long-Wave (LW) infrared bands across four fields of view and focuses it onto a staring Focal Plane Array housed in the DCB.� The B-Kit components are intended to be interchangeable Shop Replaceable Units to maximize economies of scale similar to the 2nd GEN FLIR (2GF) B-Kit.� The 3GEN FLIR B-Kit provides the ability to detect threats at greater distances under a full spectrum of conflict and battlefield conditions. 3GEN FLIR enhances the platform's effectiveness and survivability by providing greater situational awareness promoting combat effectiveness and reducing fratricide.�� The 3GEN FLIR B-Kit will replace the legacy 2GF B-Kit and Thermal Receiver Unit (TRU) on the Abrams M1A2 System Enhancement Program (SEP) V4.� The 3GEN FLIR B-Kit is designed to fit and function while subjected to the thermal, vibration, and shock environments for the M1A2 SEPv4 Gunner�s Primary Sight (GPS) and Commander�s Primary Sight (CPS).� For the GPS configuration only, the B-Kit is integrated into the TRU as a sub-assembly which includes a Personality Module CCA, Electromagnetic Interference Filter, afocal guard, and electrical flexes mounted in the TRU mechanical bench.���� The TRU, B-Kit sub-assemblies, electronic modules, and the DCB, defined under RFI # W909MY-20-R-C026, will be integrated on host platforms to compose an Improved FLIR sensor. The B-Kit provider will be responsible for integrating the GFP DCB into their B-Kit design. The DCB will be provided as GFP to the B-Kit provider for final integration and testing.

General Dynamics Land Systems will add new training software and cybersecurity capabilities to the next generation of the M1 Abrams main battle tank under a contract the Army announced Feb. 19.

The Army will pay GDLS $25 million "to incorporate the Abrams Platform Embedded Training System Gate-To-Live-Fire capabilities and fault insertion language" into the Abrams M1A2 SEPv4, the announcement stated.

"This software update provides the opportunity to increase virtual opportunistic training capability for Abrams tank crews while reducing dependency on the Advanced Gunnery Training System (AGTS) as the primary provider of synthetic training in" Armored Brigade Combat Teams, Ashley John, a spokeswoman for the Program Executive Office Ground Combat Systems, wrote in an email to Inside Defense.

In addition, the contract includes "additional cybersecurity capabilities and replacement of the Loader's Portable Multifunction Display with the Mounted Family of Computing Systems tablet" for the SEPv4, according to the announcement.

Came across a document on the LV100 engine which has a tidbit on the ASM program:


Apparently, Teledyne ended up winning and producing a vehicle, though the image quality isn't great.



Is there any more info/photographs of this thing out there?

Also, JIDR 1996-02 apparently has 3-page article on the subject, but RSL does not have it.


Upd: Andrei_bt has this article, translated into Russian


Earlier issues of JIDR and of other magazines from 1994-1996 should have something too.

Had the fantastic opportunity to PMCS, boresight, and road test a M1A2 SEPv3 from 4-9 CAV at Ft. Hood today.







Many images:

I can confirm the photo I posted previously that the turret weight of the SEPv3 31.5 tons (28.6 metric tons). I have a photo of the name plate but I haven't removed the serial numbers to upload it. 


I also made an extremely rough estimation of the turret armor LOS using my boot and then measuring my boot after (I didn't have a measuring tape on the tank nor did I want to piss off the crew). Using this very rough method I found the armor to be at least 1150mm LOS including the backplate. 


I may be able to get back on a SEPv3 next Monday.

      Volketten on the WoT forums posted some XM-1 trials results.
      Compare this to what the Americans claimed the XM1 will do:

      Seems like the XM1 really didn't earn that checkmark-plus in mobility or protection.

      So National Geographic has a mini series airing right now called The Long Road Home. I'm curious if any else is watching it right now. The show is about black Friday, and the beginning of the siege of sadr city in 2004. It's filmed at Fort Hood with cooperation from the U.S. Army so it features a lot of authentic armor. The first couple of episodes feature Bradleys quite heavily, and starting with episode 4 it looks like Abrams starting getting more screen time. It's pretty cool if you want to see some authentic tanks and vehicles as long as you can stand some cheesiness and army wife shit.
      Edit: Just realized I posted to the wrong board.

      Well, if you include TUSK as armor kit for the Abrams, then you also have to include the different Theatre Entry Standards (TES) armor kits (three versions at least) of the Challenger 2. The base armor however was most likely not upgraded.
      The Leclerc is not geometrically more efficient. It could have been, if it's armor layout wasn't designed so badly. The Leclerc trades a smaller frontal profile for a larger number of weakspots. It uses a bulge-type turret (no idea about the proper English term), because otherwise a low-profile turret would mean reduced gun depression (breech block hits the roof when firing). There is bulge/box on the Leclerc turret roof, which is about one feet tall and located in the centerline of the turret. It is connected to the interior of the tank, as it serves as space for the breech block to travel when the gun is depressed. With this bulge the diffence between the Leopard 2's and Leclerc's roof height is about 20 milimetres.

      The problem with this bulge is, that it is essentially un-armored (maybe 40-50 mm steel armor); otherwise the Leclerc wouldn't save any weight. While the bulge is hidden from direct head-on attacks, it is exposed when the tank is attacked from an angle. Given that modern APFSDS usually do not riccochet at impact angles larger than 10-15° and most RPGs are able to fuze at such an angle, the Leclerc has a very weakly armored section that can be hit from half to two-thirds of the frontal arc and will always be penetrated.

      The next issue is the result of the gunner's sight layout. While it is somewhat reminiscent of the Leopard 2's original gunner's sight placement for some people, it is actually designed differently. The Leopard 2's original sight layout has armor in front and behind the gunner's sight, the sight also doesn't extend to the bottom of the turret. On the Leclerc things are very different, the sight is placed in front of the armor and this reduces overall thickness. This problem has been reduced by installing another armor block in front of the guner's sight, but it doesn't cover the entire crew.

      The biggest issue of the Leclerc is however the gun shield. It's tiny, only 30 mm thick! Compared to that the Leopard 2 had a 420 mm gun shield already in 1979. The French engineers went with having pretty much the largest gun mantlet of all contemporary tanks, but decided to add the thinnest gun shield for protection. They decided to instead go for a thicker armor (steel) block at the gun trunnions.

      Still the protection of the gun mantlet seems to be sub-par compared to the Leopard 2 (420 mm armor block + 200-250 mm steel for the gun trunion mount on the original tank) and even upgraded Leopard 2 tanks. The Abrams has a comparable weak protected gun mantlet, but it has a much smaller surface. The Challenger 2 seems to have thicker armor at the gun, comparable to the Leopard 2.
      Also, the Leclerc has longer (not thicker) turret side armor compared to the Leopard 2 and Challenger 2, because the armor needs to protect the autoloader. On the other tanks, the thick armor at the end of the crew compartment and only thinner, spaced armor/storage boxes protect the rest of the turret. So I'd say:
      Challenger 2: a few weakspots, but no armor upgrades to the main armor Leclerc: a lot of weakspots, but lower weight and a smaller profile when approached directly from the turret front M1 Abrams: upgraded armor with less weakspots, but less efficient design (large turret profile and armor covers whole turret sides) So if you look for a tank that is well protected, has upgraded armor and uses the armor efficiently, the current Leopard 2 should be called best protected tank.
