    Sure. I've got some peculiar recipes that have had very promising results both with the Lanz-Odermatt formulae and with the extreme-hardness/extreme-velocity calculator I wrote to make up for when L-O stops working due to shifts in how the penetrator and target behave at like 1750m/s impact velocity. Are segmented rods OK, or do we need to stay monolithic?

    I was referring to mixing tungsten into the steel alloy — several of the alloys I looked at for the California contest were not viable there because they contained >100g of tungsten in “herbs and spices” of alloying elements, and that was prohibited. If it’s not allowed, that’s fine, I have non-tungsten-containing alloys for the penetrator I can use as well.

    Very good! Thank you. Specifically speaking to steels, is there a limit on tungsten or other alloying contents? I had been experimenting predominantly with low-tungsten alloys as a result of the Californian program, but if I can toss in some new herbs and spices it would be interesting to see the results. Additionally, if I desired the use of some exotic steels in armor, and can provide validation of claimed performance, is that allowed?

    It'll be an interesting time, that's for sure. It'll be nice to work up and refine the design I have so far -- the NERA arrays should be pretty darn effective, all things considered. It'll be nice having a relatively simple design compared to the Californian gold-plated technotank.

    I'm sticking with a forced induction diesel V-12, although the option of a turbine is interesting and may be compelling given the climatic conditions in the northern areas of Texan territory, a la the Russian Federation use of T-80 in their far northern areas. That being said, the 2240 cubic inch 60-degree diesel V-12 makes sufficient power when the specific power output of the AVDS-1790 is considered that it is more than sufficient for a vehicle of the protection and armament I am working with. Also, as a solution to the loader situation, I'll be bringing an autoloaded 5"/48 gun in a welded box turret. @N-L-M What's the L:D permissible for steel DS penetrators?

    I'll be submitting a cartridge once I finish working it up, probably by the end of the week. Currently I am estimating in excess of 900ft-lb and 32 pine boards at 600 yards, and above the transonic regime to 1,000 yards. I have not downselected fancy bullet designs between a monolithic gilding metal OTM and a reverse-base-drawn exposed penetrator AP design. I have high hopes for this cartridge, and believe that it will prove quite successful.

    What if we did an airplane contest next?
  8. A. T. Mahan
    @Toxn We will be submitting our design today
  9. A. T. Mahan
    I'm looking forward to seeing what else turns up aside from Toxn's and my team's stuff

    Question: Where do we discuss the entries, here or the submission thread?
  11. A. T. Mahan
    We explain it all quite thoroughly in the proposal paper.
  12. A. T. Mahan
    That’s not at all what I did! If anything, it’s more similar to a Pershing II

    In further pursuit of open discussion of the development of tracked vehicles, SNVZ is proud to offer the RSD-1 Innovator intermediate range ballistic missile complex, capable of delivering a 425kg warhead to 1,800km with sub-100m CEP, or a heavier warhead to shorter ranges. Also, the tracks have gone missing. If anyone sees them, please return them. Below is an image of the 15Zh6 Innovator ballistic missile, which should deconstruct notions of masculinity and phallic imagery via its role defending the peace-loving matriarchal society of the DPRC, and deliver rapid reeducation through either chemical, high explosive, or special warheads in under 30 minutes, with a response time of approximately five minutes from receiving a launch order to firing, from the transit mode at a pre-prepared firing position.

    The answer is something like three weeks of ANSYS and a lot of research. I would have used a supersonic wind tunnel but they’re phenomenally expensive
  15. A. T. Mahan
    It's an Armor Piercing, Solid Fuel Ramjet-powered GLATGM with an 850mm long, 50mm diameter molybdenum tool steel penetrator, capable of killing the reference vehicle at ranges in excess of 7,500m.

    I have been permitted to pull back the veil of secrecy, and post a picture of the 125mm fully-tracked gun-tank Object 138, along with some vital statistics. 125mm Fully-tracked gun-tank Object 138 Heavy Tank of Novel Type Mass: <47,500kg Length: 6.76 m (hull) 15.42 m (gun forward) Width: 2.30 m Height: 2.41 m Crew: Three (Commander, Gunner, Driver) Armor: Novel composite armor in excess of objective requirements as stated in the RFP Main Armament: 125mm 2A35 high-velocity smoothbore gun with autoloader - APCBC performance in excess of M-62T2 and in excess of requirements and with engagement - 45 rounds, with 30 in autoloader. - Equipped with a gun-launched antitank guided missile of novel type "Armor Piercing Solid Fuel RamJet" 3UBM1 and 3UBM2 providing lethality against all known vehicles between 450 and 7,500m. Secondary Armament: - 7.62mm coaxial Machine Gun PKT, 3000 rounds; - 14.5mm commander’s Machine Gun KPVT Powerpack: VPK-3 Powerpack with Engine VDS-2330 and Transmission CD-1750; >1,500 horsepower; eight speeds. Power to Weight Ratio: >30hp/ton (2000kg per ton) Top Speed: 75 kph (governed) Suspension: Torsion bar, six per side; shock absorbers on all. Ground Clearance: 490mm Fuel Capacity: 1,200 liters internal, 416 liters aux. drums Operational Range: 460 km internal; 720km w/drums The vehicle is also equipped with advanced digital computer systems for fire control and 1,200-1,600 FOM image intensifying tubes, details of the manufacturing processes of which will be discussed in our proper submission paper. The vehicle is also equipped with advanced encrypted radio equipment using the novel TSEC/KY-57 FEINSTEIN unit, details of which will be discussed in the submission paper. Here is a larger version of the above image. 3UBM2

    @Lord_James NLM has previously said that these are not available for vehicle armor (I already tried)
  18. A. T. Mahan
    Define "Armor" -- do I count the turret and hull structure, or just the armor packages?
  19. A. T. Mahan
    That reminds me, we should all make sure to put Prop 65 warnings on everything
  20. A. T. Mahan
    @Lord_James Where does the turret ring go?
  21. A. T. Mahan
    @N-L-M Thank you! For the weight-lifting capability, is this lifting to like shoulder height or above their head? Also, could you clarify: What should we use for the mounting bracket weight for ERA/NERA? 10-30% is a wide variation. And Is there a specification for the steel one might use in a kinetic energy penetrator, specifically in terms of hardness?
  22. A. T. Mahan
    That's the spirit! But seriously, if the TC has turn out for a patrol and gets shot by a Mormon sniper, it'd be nice if they had some more protection than their uniform top and a cigarette case.
  23. A. T. Mahan
    I mean I just want to know if NLM will let me play with my aramids and para-aramids or not
  24. A. T. Mahan
    I mean, it'll be something pretty light, like the CVC Armor Vest, maybe with plate bags for a fairly low profile rifle plate.
  25. A. T. Mahan
    I just want to give the tank crews fire-protective clothing and body armor. It's nothing to do with the tank armor itself, but with keeping the crew from burning to death or getting killed when some Mormon shoots them in the chest while they're turned out.
