Then use your knowledge of the subject to infer their meaning. Jesus Christ. If someone says 'oh yeah, the CV(T)', I'm capable of working out 'maybe they mean 'CVR(T)' because there's only a letter misplaced'.

besides, the CVR(W) were much cooler

slightly sexier (DAT VIXEN!) but not cooler.

Pffffft, this is what Syria gets when they combine the T-34 And The D-30, ITS SO CUTE YA!

carden lloyd based tankeetes are generally pretty cute little beasts.

Plz, don't make me shame you all with my creepy collection of moe tank girls.

Guys what do you think by what exstend can you armor a tank of 95 tones armed with a 140mm ETC gun? We are talking around 2017-18 timeframe in a perior where there was no end to the cold war.

[Novorden]

95 tonnes

After hours of constant shelling, 2nd tank regiment tried to hide from the enemy spotters, however something kept giving away their position....

[Gallia-]

Died of cute.

Sure that happens
My main plan for the M7A1 variant of tanks is to have a 140 mm gun, and at max be at around 95 tones. So that is why I am asking about to what extend I can realistically armor its front of the turret and the frontal plates.

[Imperializt Russia]

Why demand a 140mm ETC gun?
A 140mm gun will kill anything anyway.

[Teronia]

I've just realized that I lack any mid-scale indirect fire capability.
So yeah, other than 16" guns with insane range, I need something, preferably either 155mm or 203mm, that can put down accurate fire at ranges up to 100km. (To support my heavy artillery units, who have a 56km minimum range. They have some weapons that can cover the gap, however they are too powerful for any sort of surgical attack)

Maybe a refit of the M109A6 paladin? I'm moderately FT, so advanced superdense armor, nanomachine assemblers, and small fusion reactors are the norm. Meh, what do you guys think?

Contrary to popular belief, range of a projectile has nothing (directly) to do with caliber. This is a land-based 16-inch gun that actually existed, and it had a range of just over 25 kilometers (it also took 5 minutes to reload). As any high school physics teacher will tell you, range is a function of velocity and angle of elevation; air resistance and gravity also play a role. If you want to extend range, then either design a higher-velocity gun, or load rocket-assisted ammunition. If you want to reduce range, then load ammunition with a weaker charge or fire at a different angle.

I also don't see what you mean by "minimum range" here... can you explain this a little more? Most howitzers without direct fire capability are inaccurate when fired like an anti-tank gun, but that zone of minimum range is rarely less than 5km. How is your minimum range longer than the maximum range of the long-range howitzers in service with most RL nations?

For reference, a look through the examples on this list can help you determine what realistic, believable ranges would be. Note that ranges of over 100km are hard to find, with 30-40 km being more typical. For "insane range," you're better off using a cruise missile.

If you really want to play the FT card and say "we have ultra-velocity artillery and coilguns/railguns, so this doesn't apply," then all bets are off. But based on real-life trends, the greatest technological advancement in the field of long-range combat will likely be in the area of missiles, not guns.

Welp, it took forever for me to get back on the 'net, and you guys post fast. Anyway, yes I am aware that range has nothing to do with bore diameter. However, I need something that can fire existing 155mm, 152mm, and 203mm smart shells. Shells that I am using as a counter to my foe's anti-missile defenses.

As to the minimum range bit, my big guns are accurate just about anywhere in their reach. The problem is that they hit really, really hard, and that minimum range means that the platform won't be destroyed by the blast. (It fires either supermaterial kinetic impactors, fusion airburst rounds, or small scale clean WMDs. Thus the minimum range.)

For the unit I'm looking for, it will be able to generate enough power for a mass driver with that range. The only problem is what I should base it off of.

[Imperializt Russia]

None of those should probably pose a significant threat to the launching unit if used over the horizon. If they will, why in the name of everything are you using them as artillery?

[Mozria]

Hey, gents, I have a question on my APFSDS projectiles.

I am re-doing the stats of the CDH-14M 146 mm 45-caliber cannon that is mounted on the Manticore-IV, but I am not sure of the diameter and weight of the penetrator that I want it to fire. It is of a long-rod configuration, and is composed primarily of depleted uranium (with the exception of the stabilizing extension and fins). My current stats place it at 16 kilograms for the projectile weight and 5 kilograms for the sabot.

Are these good measurements for a 30 mm-diameter penetrator, or am I overdoing it a bit?

Hmm... i believe the abrams uses a 120mm 39lb projectile, and the sabot is, what, 5lb?
Not sure how that translates to kilograms though. I'd say a 16-18kg rounds and a 1-2 kg sabot

I have no clue then.

I usually have to face either rediculously armored opponents or those with shielding capabilities. So I usually lug around variable yield WMDs rated from 5kt to 10kt. The kinetic impactor actually releases more energy than the WMDs, but needs something hard for it to do real damage.

The platforms don't take massive doses of EM radiation well, so I need a hefty safe distance from the blast.

[Imperializt Russia]

The M829A2, according to ATK who manufactured it for a time, had a projectile weight of just 10kg

The M829A2 (full cartridge) is 41.1 lbs total, so I do not believe that the penetrator would weigh as much as you are thinking. It is likely in the ~10-12 kilogram range versus the 18.6 kilograms of the full round.

The penetrator for my round is ~5 mm thicker than the ~22-25 mm-wide penetrator used in the M829A2, and so would probably be a few kilos heavier. I have no idea of the sabot weight, however, as the bore diameter is 26 mm wider than that of the standard M256 and the cartridge is of a much higher pressure (roughly 590 MPa versus the ~550 MPa of the M829A2).

Oh, my. I certainly am not experienced in these kinds of mathematics yet, so I will just fiddle with things until I get something along the lines of what I desire (it is in a calculator, correct?).

[The Kievan People]

That is basically what I do...

[Mitheldalond]

The M829A2, according to ATK who manufactured it for a time, had a projectile weight of just 10kg

If I recall correctly, that weight includes the sabot. The penetrator itself is about 7kg. It shouldn't be too hard to calculate though.

M829A3 penetrator is 800mm long and 25mm in diameter.
Volume of cylinder = V = πr²h = π((.025m)/2)²(.8m) = 3.926x10^-4 m³

Density of DU is 19,100 kg/m³.
3.926x10^-4 m³ x 19,100 kg/m³ = 7.5 kg

[Imperializt Russia]

With the wrong numbers, you've ended up at an approximately correct value.

M829A3 is probably notably heavier than the M829A2, on account of different, larger design.

if you have a Tančík vz. 33 or CVR(W) Vixen tankgirl, that would be interesting...

How could I figure out the yield strength of my KEP?
