    Tanks guns and ammunition.

    Targets for the 30 mm APFSDS ammunition from Rheinmetall representing the BMP-3. Range unknown, but the official effective combat range of the Puma's MK 30-2/ABM is listed as 3,000 metres. The penetrator is optimized to remain intact after penetrating spaced armor arrays (which older types of medium calibre ammo couldn't do) and to create spall. In an older presentation, a 30 mm APFSDS managed to penetrated 15 mm HHA and 30 mm RHA in a spaced configuration at 45° slope and 2,000 metres distance. The official armor penetration of the APFSDS-T PMC 287 is listed as 106 mm line-of-sight against a 60° sloped plate at a range of 1,000 m in Rheinmetall's flyers. The APFSDS-T PMC 359 round (with ECL instead of EL propellant) is listed with the same penetration value.

    StuG III Thread (and also other German vehicles I guess)

    http://defence-blog.com/army/rheinmetalls-unterluess-plant-rolls-100th-puma-infantry-fighting-vehicle.html Don't be confused by the title. This is the 200th Puma already delivered to the Bundeswehr out of 342 on order, with the final unit delivered sometime around 2020. I just hope they're not thrown into some workshop because of certain shortages like they did with tanks, aircraft and whatnot.

    I've got to say, an American and an Israeli both trying to claim the moral high ground in a thread about Syria...

  10. Researcher lands "dream job" of studying bears in montana, promptly gets attacked by grizzly. https://www.greatfallstribune.com/story/news/2018/05/22/montana-bear-researcher-dream-job-attacked-grizzly-amber-kornak/634343002/ A government wildlife worker who recently landed her dream job researching grizzly bears in a Montana mountain range is recovering from a bear attack that left her with a fractured skull and other serious injuries. U.S. Fish and Wildlife Service seasonal field assistant Amber Kornak was attacked on May 17 while working alone near a stream in the Cabinet Mountains, agency spokeswoman Jennifer Strickland said. While being mauled, the 28-year-old Kornak managed to reach a canister of Mace-like bear spray and ended the attack, inadvertently spraying herself in the process. She then walked to her work vehicle and drove to find help, according to Strickland. Working with grizzlies had been a longstanding career goal for Kornak, who is recovering at a hospital in Kalispell following surgery for the skull injury and from severe cuts to her head, neck and back, said Jenna Hemer, a friend who spoke with Kornak following the attack. ... Kornak was working at the time of the attack on a genetic study that requires collecting grizzly hair samples. The hairs can be found on trees or other objects that grizzlies rub against, and are used to analyze the animals' DNA. ... So... mission accomplished?

    Well done, Twitter.
  18. Perhaps that's why they made a new common link, instead of using the legacy KPV link? You are either going to use a semi-rim or belt on a cartridge like that. I wouldn't trust the rotating band for headspacing. FWIW: The US played with its Cal .60 case by necking it down to 12.7mm and all the way up to 27mm before deciding upon the 20x102mm.

    That is far from the case and fuck you very much too... If you can get that from what I said, that says EVERYTHING about YOU. I have a problem with the person not the ethnicity religion or etc, which I have made quite clear. I hate assholes not JEWS ... I guess I have to be that fucking specific so I will be. I'd think it would be clear by how I can be very strident about certain political stuff with other posters, but if they post something about the Gerlach periscope I will happily discuss that with them and upvote posts of theirs that I like on other parts of the forum. It's my opinion which I reserve the right to have, and to change at any time should circumstances change. But I sure fucking won't let someone weasel out of having me say what I think because of some notional whatever that makes them somehow above reproach. And I also won't sit still and let people back handedly imply that I'm calling someone out because of some concealed racism rather than because I think they're being a smarmy asshole.

    https://forum.warthunder.com/index.php?/topic/412220-development-xm-1-c-and-xm-1-gm-ancestors-of-the-abrams/ Top tier performance just a credit card payment away... Not only do they have armor resistant to 115mm KE and 125mm HEAT, they also have stabilizers... I guess mental paraplegics need to play video games too, because they're giving away all the crutches with these tanks...
  22. Also, what is that automatic grenade launcher sitting to the side of the three-ammo-in-one belt? It isn't an AGS-30. Ammo looks different too.
  23. If it is semi-rimmed but the others are not, how does it fit into the common link? I'm pretty sure that the dummy cartridge on the left of the picture is 14.5x114mm. The proportions look about right, and all Russian ammunition of larger caliber is extensively crimped at the neck. Ironing out a 14.5mm cartridge would get you about 25mm. The brass AGL cartridge is also clearly a dummy. And it wouldn't have been too hard to make that necked-down 12.7-14.5mm wildcat either. This entire thing strikes me as the sort of thing that could be made easily and cheaply as a way to impress officials. Then the company could begin actually working on the concept once they secure funding.

    Aerospace Pictures and Art Thread

    I hadn't thought of the weight savings in the structure with an evenly distributed load across the wings (avoiding the reinforcing to take the massive moment at the wing root). Other takeaways: - This was meant to crab sideways into a long thin hangar - post-war defence budgets must have been very tight with the number of times that they mention "efficiency" - The fins on top weren't connected as rudders - the rudder was achieved with differential airbrakes in the wingtips. This meant that both rudder pedals were separate, and if you pressed both pedals then you got an airbrake

    I don't even know what's going on with all the different sides sniping at each other. It's like a Syrian Civil War cosplay on the Open Thread with all of the different sides.
  27. I’ve only seen S3 testing done with small arms. Have an agreed number of natures of ammunition tested a “qualified” for Initial Materiel Release (IMR)/Initial Operating Capability (IOC), then do the rest to get to FMR/FOC. So, in the case of a new rifle, you could have ball and blank at IMR/IOC, then reduced range training ammunition, frangible ammunition, tracer, armour piercing, and simunition by IMR/FMR. Way more complicated for mounted systems, especially when considering recoil & feed systems. I would’ve thought using the Mk44 off the shelf would’ve been lower risk, but that’s just a gut feel.

    General news thread

    https://www.dvidshub.net/news/277313/exercise-saber-strike-18-take-place-june Well this is interesting. Apparently Israel will be among the countries participating in Saber Strike 2018. It may need some context; Israel has been trying to get into NATO for quite a while now, and only been blocked by Turkey so far. Although last time I've heard about this a few years ago the plans were to integrate only the navy to NATO. I have a feeling though that this will just be a couple of advisers and observers. Maybe someday we will see those shining Merkava tanks plowing Polan... I mean driving around Europe with NATO troops.
