    Quite interesting M1A1 uses same spacers for crew compartment side armor as front ones

    An updated design of the Hyundai Rotem Next Generation Main battle Tank was showcased recently at the autumn conference of the Korean Institute of Military Science and Technology. Don't have much other in the way of info.

    A rare picture: an overhead shot of the M1 Thumper, used to test the XM291 ATAC gun (sometimes referred to as LW120) in conjunction with the XM91 cassette autoloader.
     

     
    The Thumper, which was built out of a M1A1 at Anniston Depot, used a 120mm XM291 in three different barrel lengths, one 265in/6.75m long (the standard, "long tube" XM291), a second one cut the same length as the M256 ("short tube", 5.3m) and a third, intermediary one ("medium tube") that stands somewhere between 6.75m and 5.3m.

    On-the-move test fires done at speeds of 10, 15 and 20mph showed that the target impact dispersion (TID) was bigger (read: lower accuracy) with the "long tube" XM291 compared to the "short tube" or EVEN the M256, which was problematic. To support the increased barrel length, Benét Labs also had to create a 415lbs and 22in-long extension for the gun cradle...which was later reused in the proposed installation of a XM360E1 inside the notional M1A3...and, quite likely, inside the M1 AbramsX demonstrator showcased at AUSA 2022.
     
     
     
    The 1988 M1 Thumper was only fitted with the 120mm ATAC gun, but the XM291 installed on the 1993 M1 CATTB, on the other hand, went on to trial a 120mm and a 140mm barrel. At one point, the ATAC prototype pool was noted to have successfully fired 1,300 rounds, 150 of which were of the 140mm variety. The latter (at least the KE part) was even judged capable of defeating the armor of what was tentatively described as the FST-3 (Future Soviet Tank 3, essentially a Obj.477/477A); there are no known numbers for the 140mm XM964's performance, but the 140mm ATAC itself was expected to produce a great maximum of 25MJ of muzzle energy. The ammunition for the ATAC was developed by Valentec International and Hercules.
     
     
     
    While the Thumper was originally meant to trial the 120mm ATAC, some of the official literature indicates it may have also undergone the 120-to-140mm tube conversion and done static test firings at Aberdeen Proving Grounds, where it showed precision equal to a M1A1 but "with greater penetration".
     

    >> Source document for the two above scans <<
     
    Also, a common mistake (one I've also been guilty of, mea culpa) I often see around in forums and milblogs is that the Thumper is a derivative of the CATTB, which is false, as the Thumper (AKA the ATAC Demonstration System) predates the CATTB Phase I by at least five years.
     
    M1 CATTB Phase I (using a M1 hull as basis), in 93/94, about to be shipped to Aberdeen Proving Grounds for testing:
     

     
    Picture of the CATTB Phase II (ATTD?) hull under construction, completed in 1994. Note the closed back with no exhaust grille, the absence of apertures for torsion bars (replaced by a hydro-pneumatic suspension system) and the smaller engine compartment designed to receive a Cummins XAV-1000 AIPS instead of a Honeywell AGT-1500. The freed-up volume between the XAV and the turret basket was reclaimed to accept two vertically-stacked non-ready cassettes housing a total of 22 rounds (either single-piece 120mm or two-piece 140mm), which would have given the CATTB Phase II a maximum loadout of 39 rounds (either 120mm or 140mm), just five less than a M1A2. The huge tradeoff, of course, was that all this made the CATTB massively overweight.
     

     
    Apparently, at least one of the two CATTB testbeds is currently sitting at the Sierra Army Depot in Herlong, California, but one has to wonder if it's not a case of mistaken identity; the Thumper was, after all, spotted in 2010/09/30, in Ohio, as it was being relocated by train to parts unknown. Here's to hoping any of these big bois shall make their way to a museum one day, as did the TTB, the Crusader and many others before them.

    In current year low-recoil 30/35 mm autocannon with proximity/electronic time fuzes in RCWS makes more sense than MGs only in RCWS. Infantry in cover, drones, shit like that is easier to at least damage with airburst/AOE weapon rather than direct bullet hit. Would be better if they had 7.62 MG as second weapon, for suppression, but that could be a bit too heavy and eat too much space.

    So this showed up today

     
    First glance, seems like a modified hull with extra periscopes which would be the case if the crew was to be taken out of the turret and into the hull. But on the other hand, the shape of the turret seems to be the same classic Abrams pre SEPv3.

    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.

    "The Army is currently testing a fleet of Next Generation Combat Vehicles (NGCVs) at Project Convergence 2021 (PC21), a large-scale modernization experiment and cornerstone effort of U.S. Army Futures Command.
    As part of the experiment, which is taking place at Army installations in Arizona and New Mexico, teams of Soldiers, civilians, contractors and industry experts are testing the newest advances in modern warfare, including in the realm of artificial intelligence (AI)-enabled ground combat vehicles.
    The new vehicles undergoing testing include the Army’s Robotic Combat Vehicle, Optionally Manned Fighting Vehicle and Next Generation Tank."

    It's somewhat reminiscent of the Chieftain 900. The displayed weight (52 t) seems a bit light for an upgraded Chieftain.

    Fitted with Trophy radars and Norwegian camo. It's said that this K2 will be spotted at the upcoming ADEX 2021 (along with the Desert K2 we've seen at expos in the past) so we may get more pictures and details then.

    M1A2 SEPv3 being used to test a new German railcar to support increased weights.
     
    However, interesting to note is that this particular tank came from the prepositioned stocks in Mannheim, Germany. Therefore it seems that at least some portion of US prepositioned armor in Europe is made up of SEPv3 tanks (in a gorgeous three-tone paint job).
