Event vehicles are never equal to the best vehicles in a tech tree.
The M1 CATTB would be a M1A2 SEP v2 sidegrade at worst, and that’s assuming it mounts the 120mm barrel and not the 140mm.
Something like an M1E2 or M1A2 M256E1 seems more likely to be a event vehicle than the CATTB, though the M1A2 M256E1 would be incredibly difficult to balance given (if I remember correctly) it did not have a functional stabilizer.
So where would you put an M1A2 with superior firepower to a Leopard 2A7V but without stabilization?
Even the 11.7 M1A1 is already better than any MBT in the entire Russian tech tree, so that’s not really true.
But that’s what M1’s are IRL as well?
Even the M1A2 SEP v3 isn’t really that significantly different from a SEP v2, we’re gonna have to wait for the later stage prototypes of the M1E3 before we see what a real majorly overhauled M1 looks like.
The wide range of muzzle velocity figures is thought to be due to the large number of 140mm APFSDS prototypes that were made.
Not only in the United States, but in other countries as well, many prototype APFSDSs were made, and some of them had short penetrators weighing around 5kg to 6kg in order to research how to improve muzzle velocity, achieving a muzzle velocity of 1900m/s to 2000m/s, while others had penetrators that were made as thick and long as possible in order to research the impact force due to weight, only achieving a muzzle velocity of around 1500m/s.
The existence of multiple prototypes like this is thought to be the reason for the wide range of muzzle velocities reported in the documents.
It should also be noted that the 140mm APFSDS used a structure in which the penetrator was wrapped in a thick steel sheath to withstand the energy of firing, so even if the penetrator’s diameter was around 25 to 28mm, the diameter of the APFSDS itself including the sheath was around 45mm (some prototypes reached a diameter of 54mm).
EMBT is a “look we can work together” but IT WAS worked on together by KNDS Germany and and KNDS France.
Strictly speaking, the EMBT in all of its forms, should be in both TTs, whereas Leclerc Evo which also uses the ASCALON, should be France’s, just like Leopard 3 is only going to be Germany’s.
A magic fairy called M829A2 technical schematic told me (the entire reason I’m even talking about this confidently is cus I have both for M829A2 and DM53/63 lol).
this is absolutely wrong, it is 4.9-5kg depending on source
DU penetrators dont gain as much more penetration with velocity compared to WHA ones. Using L-O, i calculated the penetration of M829A2 fired from L/55 (assuming the same velocity gain as DM53) to be 648.2mm
there is no such thing as an ideal cilinder, if not tips wouldnt even matter in darts, the reason there is a narrowing tip at the rear its for aerodynamics and if we were to do such a thing then stuff like 3BM22 wouldnt even be counted since it narrows at the back a lot more than what DM53 has, also any apfsds has a dip on the back made for aerodynamics, just different on each apfsds and its still counted as part of the penetrator for calculations
Which Gaijin doesn’t use. They take actual penetrator length and the average diameter.
Are you recalculating the length of the penetrator, taking into account the narrowing at the tip and rear?
It’s the width at the tip base, so it’s the “average” all things considered.
Based on your data, the weight is 5.08 kg without the cap, feathers, tracer, etc., which seems to be higher than the weight of the projectile.
And the weight of the projectile is what according to you?
Because funnily, the Germans actually list penetrator mass as “in-flight” weight, fx, DM33s actual “mass” is 4.6kg in total minus the sabot, but “in-flight” it’s 4.3kg, which is also the mass of its penetrator :)
Also funny, the bias ya got for Russia is powerful:
