the point of BLOS is that the enemy donj't know where you are. all they can see are the drones buzzing around, while from somewhere, their tanks are getting killed by an unknown enemy. also drones come in all sizes: this drone will fit into an ammunition pouch. good luck shooting that one down...

BLOS top-attack is the future of tank warfare. current armour is limited by it's ability to find good terrain to fight from, and it requires significant skill to find good battle positions with good fields of fire that doesn't expose you to enemy flanking fire. anytime you expose your tank to...

US army was developing MRM-CE up until fairly recently: XM111 120mm MRM Mid Range Munition) CE Live Fire - YouTube but dunno if it was cancelled. possibly, although it has some flaws of itself, such as larger side profile, and post-penetration spalling causing ammunition cook-off, and...

it's actually inspired by the stryker MGS, and leclerc.

quick video of an autoloader design i've toyed around with. obvious flaws are vulnerability to small arms fire and such. autoloader - YouTube turret is manned, unlike TTB design, and AL only holds 16 rounds in a conveyor belt config.

right, but there doesn't seem to be much room at all for the ammunition box. either it would have to be a belt going down the side of the gun, with the box underneath the gun, or the ammobox would be very small. seems to be hard putting the elevation motor in there though. for leopard and...

seems like a good design, very similar to TTB ;) but dunno about the double autoloader. TTB autoloader was able to contain 44 ready rounds, which should be enough. also having 2 autoloaders increases complexity and cost, and with a Remote turret that should be kept to a minimum. dunno about...

from what i've read: 17 tons with "full armour kit" 13 tons with "reduced protection".

actually, talked With Nils, for armour penetration we use target hardness of 237 BHN as recommended by odermatt. in that case, things looks a little different. we get a perforation of 856mm. almost exactly the number in SB.

future tanks will be fitted with unmanned turrets, and a personal drone to scout ahead in urban warfare.

putting numbers into odematt rod length: 815mm rod diameter 20mm, speed 1555m/s density 18500 and material DU, i get 776mm penetration for M829A3

if you go by the german 2A5 mannerheim configuration, it is a total of 3850kg heavier than the A4. there is no additional front hull armour on the german A5, however there was some changes made for the sideskirts. the older perforated steel+rubber skirts were swapped with hardened steel skirts...

what would be needed is muzzle velocity, penetrator length and diameter for a decent estimate.

some more information about advanced armour that i dug up: http://www.teamdst.com/pdf/LWI_JunJul11_p13-18.pdf

japanese are apparently using "nano crystal steel" what this stuff actually is, is anyones guess, i've read "steel with an extremely hard surface coating". so maybe just a fancy name for surface hardened steel.

M829A1 penetrator is 4.6kg. length 780mm diameter 22mm from here: http://www.atk.com/products-services/120mm-m829a1-apfsds-t-ammunition/

the tests were done in 1989, the M829A1 was fielded 1 year prior in 1988. it's highly likely this is the round used in the tests. M829A1 should have a P0 of around 700mm or so, vs 600mm for the M829.

figures from fofanov: 125MM APFSDS ROUNDS 450mm@2000m for 3BM-42 and 500mm@2000m for 3BM-32.

yes you are correct, M1A1HA was fielded in 1988. before that it was M1A1 in 1985 and M1IP in 1984.

~680mm figure is for 1991 desert storm M1A1(HA) with DU armour, original 1980s M1A1 abrams had "less" protection. afaik, original M1 had about ~450mm front turret armour vs KE.M1A1 had more, probably in range 500-600mm vs KE
