    I don't see how this would make it any cheaper. Radar and laser proximity fuzing has been around for quite a while and is fitted on Sidewinders and AMRAAMs. To kill small targets you need a small terminal miss distance, which usually doesn't come cheap.

    Electro-optics don't come cheap and the Tamirs don't have transparent noses. But what they do have is fucking huge air-search radars controlling them, so midcourse works, and terminal SARH is possible even with a cheap shitty low-gain reciever (as the targets have no EW). As the Israeli air search/ fire control radars are all AESAs, they could probably timeshare illumination like the De Zeven Provincien's Thales APAR, overcoming the problems of SARH illumination bottleneck saturation. Even with all the above considered, the 50-100k price tag is suspiciously low.

    nice, but seems to have limited coverage. In other news: >hull armor improved >Hull spaced armor added >sideskirts added >Sponson boxes added >slight experimentation with the sand colors. The 145mm gun is still in because it's the worst-case for sponson clearance. Like the turret, the hull spaced armor contains stowage space. The frontal slope would probably be used for stowage of tools, or alternatively layers of glass textolite. The other boxes will be described at some length later. All can of course be fitted with ERA when ready, and the all the thick plates are high-hardness for the shattering effect.

    won't help them in the least, but they're welcome to try.

    Mine started off as a product-improved T-55. Turns out if you tweak things and use more advanced tech than was available when the T-55 was developed, you can cram in a 145mm separate-loading gun. This of course only popped up because @Sturgeon and I had a bit of an arms race. The standard armament for me was and remains 105mm for now.

    Can you imagine what must go through the minds of tankers, raised their entire careers on the M6, when they first see the monstrosities we are cooking up? And yes, we're basically skipping a generation and a half at least. Also, think of the guys in the Deseret armored cars, barely proofed against fiddycal fire, having to go up against these beasts.

    The turret now sports spaced high-hardness armor to shatter those pesky ultra-high velocity APCR rounds our engineers are convinced will be all the rage in the near future. These are bolted and easily replaceable with, say, ERA arrays when it becomes available. The internal pockets have roof doors and are intended to hold small-arms ammo or ration boxes.

    For the non-believers, 145mm: Bore evacuators will be fitted as standard to all guns.

    Following up on a bit of an arms race on Discord, the Norman can now freely accept 125mm guns and potentially guns up to 145mm.

    Driver's hatch is now a thing: Turret had to be slightly raised and enlarged to ensure the gun clears the hatch and periscopes at full depression. For those wondering, yes the driver is mildly supine. I didn't model an IR-capable hatch because I'm lazy and didn't want to make yet another component so I just used the standard periscopes. This swinging hatch design with the periscopes mounted is inspired by the Leclerc and Leopard 2. The problem with it is that the resulting access hole is smaller than the hatch dimensions would suggest, as the periscopes must remain within the hull. For early IR, which is much larger than natural-light periscopes, the solution is to have the driver dismount the scope before opening the hatch. The IR periscope needs a rotating mount as there's only one, with a limited FoV. but maybe that can be handwaved as the head being the same as the daylight periscope and therefore fitting in the same well. Clearance illustrated: The commander has some, if limited, vision over the GPS even at full depression, allowing H-K operation. The cupola is fitted with commander's traverse and elevation override, with slew-to-cue. I'm really liking how this is shaping up. EDIT: current weight, including hull, turret, gun, extras, final drives (modeled as part of the hull for now) tracks and suspension come out at 30 tons. To do this some densities were rectally extracted (wheel hubs include ball bearings and quite a bit of air, I approximated it as half empty, likewise most of the volume of the wheels are rubber) So assuming suspension is 8-10%, tracks 8--10%, armor 50%, and the gun 5-7%, this means I've got around 70%-75% of the weight accounted for. This in turn leads me to a final weight of around 40-42 tons. Good. The tank now also has a name: XM-2239 "Norman" Named for General Stormin' "did you hear he died" Norman Schwarzkopf.

    Well IIRC the PzGr 39 was actually a very good shell against unsloped armor, while the BR-365 was uncapped and had a larger filler cavity, reducing its penetration. Try DeMarre-ing similar shell designs from different guns, say PzGr 39 from the KWK 36 and KWK 40.

    What does this even mean? 1st gen=MCLOS 2nd gen=SACLOS 3rd gen= F&F 3.5 gen (Rafael term)= F&F, man-in-the-loop 4th gen=?? 5th gen= Anti-APS??

    Brimstone is pretty much a Hellfire derivative, and Hellfires are usually quoted at around $100k apiece

    Looks like an M577.

    Quick question for those who know about this stuff, I've seen some odd numbers for missile costs around the internet and would like your opinion. The numbers I've seen suggest that ESSMs and AMRAAMs cost around $ 1M, and that Sidewinders go for around 500K. This is all very nice and pleasant, but then the numbers for the Israeli Iron Dome are around 50k-100k per interceptor. The question is- are these numbers realistic? If so, why is the iron dome so damn cheap, relatively speaking? The missiles aren't much smaller than sidewinders and the guidance doesn't look to be very primitive.
  18. N-L-M
    That looks pretty wild.

    This is a thread I wanted to post in for a while, and now I'm getting around to it. Spoilered to avoid wall-of-text syndrome. *weapons-grade naval autism warning* The reason the US carriers are the size they are is pure capability. The 90kton carriers have significantly more capability than their smaller bretheren, for a few reasons. There are a few notes I want to address on this point. 1. Deck size 2. Survivability 3. Force concentration 4. Why then, if big is so good, aren't they larger? 5. Are carriers the future? There is more to say, and I may have a follow-up post at some point.

    Turret details are now in. The turret and hull were slightly enlarged to improve ergonomics, the tank looks a bit strange now. The depicted optics are a bit of a "how much optic can I stuff in here anyway" sort of deal, I'm not sure it's even possible to make the rangefinder in the cupola work. But the idea is that when IR optics become a thing they can be seamlessly integrated. Also the gunner's line of sight is stabilized in elevation (by the magic of mirrors and electric servos), the gun drive (hydraulic) is slaved to follow it. This allows good LoS stabilization, and firing on the move can be regulated by the difference between LoS and gun (MG only, main gun from short stop). Next up on the agenda: -Sideskirts -Hull armor improvements -Sponson goodies -driver's hatch -hull interior details. It may however be a while until my next post.
  22. N-L-M
    No such thing, just start and you'll learn along the way. low-detail is fine, no need to go full autismo.
  23. N-L-M
    Thought as much, just wanted to be sure.

    living on the edge: I ended up tightening up the wheels and springs, which as this is a lighter vehicle than the Merkava and M60 (springs and wheels respectively) shouldn't be a problem. Tracks are 550mm wide, and the contact length 4375mm. the specs resulting from this will be calculated when I have a more accurate mass estimate. But for now, the track-center-pitch-to-length ratio is 1.63, the contact area 4.81 sq. m, and with 6 wheels per side the MMP won't be too high. @LostCosmonaut how "hard" a limit is the width requirement- can I have components fold out the way to fit?
