  1. It is not an autoloader, but a semi-automatic ammo rack. The ammunition is stored in a separate compartment, the gunner or loader selects the desired type of round, then the mechanism pushed the round into the crew compartment, where the loader takes it. Similar system is also used on Merkava 4.

  6. Final Judgement Third place: Carro Armato P.35/105 I hate having to place this vehicle third, as it's the most impressive in terms of paper stats and just looks so... right. It looks like exactly the sort of late-war (for them, anyway) prototype that the Italians would have produced, only for it to become forgotten under a fountain of "hurr durr pasta tank" memes. And talk about performance! What @Lord_James has managed to do here is wring a Tiger-analogue out of a 28-tonne pre-war vehicle. Unfortunately, when I try to game this thing out the numbers end up

    How we do it

    Having very recently finished a design cycle, I can now offer insight into how I do things. The first thing I do is look at the requirements, and the available options (whether limited by name or simply similar in performance), and try to figure out a first order approximation of what it is I'm hoping to get done. It's usually at this point that I sketch out the design in pencil and make a list of design features I intend to include in the design - this typically helps solidify the concept in my mind, as well as making sure I don't miss anything major along the way. I set myself certain desi

  12. My submission: "P 28/32" I used the T-28 hull and modified it by reworking the entire front and widening the turret ring to the side of the hull (it is now ~1.85m wide). The gun is an leFH 16 or leFH 18/1, German stock that is probably phased out of service by 1942-43 (the 16 was definitely not in front line service). Also, by this time, HEAT shells were starting to be added to inventory, which gives the tank the ability to engage the Sherman from the front, and from any range. As you guess by the name, the P means this tank is meant to support the M13s, 14s,

    I don't think the camera angle can explain the difference. In the photograph I posted, the hollow space occupies about 30% of the total thickness along the line of sight... that is despite the fact that most of the armor is closer to the camera and hence perspective distortion enlarges it a bit. In your image, the hollow space accounts for 22% of the total line of sight. Your protection "ideas" are way to optimistic and not based on any real life incidents. They read like the old and massively over-exaggerated protection estimates of the past. Based on the Ch

  18. NGP Render 2 Versions: IFV Variant with 50mm Rh503 (300 shots) and 6-8 dismounts, MBT variant with 140mm nPzK (30 rounds) Both variants were proposed to have significant ballistic protection (55-70t) and (as seen on the render) the Diehl AVePs APS. Both operated by 2 man crews with all around camera / thermal vision. Kind of resembles Armata platform if you ask me.

    The Leopard 2 Thread

    The source you referenced spoke about 2,200 m/s rather than 2,000 m/s though... Performance as in penetration scales linearly with KE, if the shape of the penetrator is designed to optimize it. As Rheinmetall doesn't measure penetration using steel, but rather focuses on complex armor arrays only (customers have to pay extra, if they want a test campaign against pure steel targets), it would be easier to achieve a 20% increase in penetration than actually achieving a 20% higher muzzle energy. As stated in the presentation (which was not a press release, but a

  21. At -10 degrees depression, the gun only just hits the turret roof at full recoil but the tube clips through. Limiting depression to -5 degrees solves that problem. Perhaps ejecting not with a tube but with a T-62 style roof hatch (only on the front of the turret) would allow the full 10 degrees of depression. Also apparently elevation is +15 not +10 as previously stated. I dun goofed there. The tube requires a bit of a mantlet expansion but nothing special. The latter. At -5 degrees they're aligned, as the barrel elevates and the breech drops theres a bit of a dr

    No, the gun just supports a higher chamber pressure. It does not mean that current rounds have increased pressure, velocity or muzzle energy.

  23. So apparently Norway is finally moving ahead to replace their old Leopard 2A4 MBTs. According to their "Long Term Defense Plan" they want to equip one brigade with new tanks. Currently the Norwegian Army operates 36 MBTs, if they want to equip an entire brigade of their maneuver bataillons that would translate to a need for quite a big number of vehicles. The main competitors seem to be the Leopard 2 and the K2 Black Panther. Leopard 2 upgrade proposal which was posted somewhere in this forum already South Korean K2 Black Panther (proposal for

  39. 11-12th May 1945 near Příbram, Czechoslovakia. I guess it's little known event but in fact it was a real battle in terms of scale. While the German capitulation was signed already on 8th May the war continued in Czechoslovakia for coupple more days. Fighting in Prague ceased finally on 9th May but the German units didn't want to surrender to the Red Army and intended to fight their way to the Americans. Quite a strong group of them found themseves south-east of Příbram. Roughly 6-7 thousand soldiers from various SS and Wehrmacht units, mainly remains of SS Kampfgruppe Wallenstein,

    The Leopard 2 Thread

    The Leopard 1A3's fire control system and optics were derived from the contemporary Leopard 2 development; in particular the EMES 12 steoroscopic rangefinder, the PERI R12 commander's sight and the FLER-H are based on early Leopard 2 components. But on the Leopard 2 prototypes the EMES 12 was not just an optical rangefinder. Paul-Werner Krapke in his book essentially calls it an optical rangefinder with integrated laser rangefinder, which leaves tonnes of room for imagination. The Jahrbuch der Wehrtechnik from 1974 explains some details regarding this arrangement. Basically the las

  45. GMerlon is correct but if you happen to experience a soft head failure the entire rifle is probably going to be wrecked and you are heading to the ER or undertaker. Example of a soft head failure I investigated. This happened on the sixth round in a M1 Garand. I was contacted and told him to send me all the fired cases prior to it and he did. Headspace was perfect on the first 5 and no 6 completely wrecked the Garand. This round was loaded in Britain for the Greek Army in the 50s and found out this arsenal had these prior.
