This is true, though it can be difficult to find official information on penetrator dimensions and mass, it’s the only real passable way for apfsds rounds to be fixed.
This isn’t out of bias or lack of belief in the provided material. It’s been due to lack of necessary complete official information to properly calculate the penetration of the round. Taking estimated measurements off of images just isn’t feasible, due to lense distortion and parallax, among other things.
To answer someone else, yes I submitted the information a while back, though I need to edit it a bit soon to refine it and bring it in line with US penetrator designs of the 1972-1980 period.
Does anyone know why the HSTVL can’t operate with one crew member aside from the commander? From what I understand, the driver and gunner can both drive, shoot and use the commander (hunter/killer) view. I’d like to see this added to the game.
Same with the RDFLT. Both the driver and gunner can operate and shoot the main gun. The hunter/killer system is missing as well (commander view) It can rotate independently from the turret.
Does the RDFLT have it’s own gun optic or is it just the hunter/killer system?
The TVs that the gunner, driver and commander use can all display the gunsight output, commander optic output or driver camera output. They all have controls that can manipulate the turret, gun and hull when needed.
RDF/LT and HSTV-L are the sole two turreted tanks that actually should remain combat capable with only one crew remaining.
the driver cannot operate the gun; they can likely see the gunners view but they cannot operate the gun, however true information is likely classified since the army still has the HSTVL in “storage” but its in bad shape
“being developed”, it’s not relevant to the final iteration of the HSTVL, if you can provide an updated source that was created after its completion, that would be a different story
I also noticed this, about 25.4mm of homogeneous armor and 25.4mm of aluminum. Notice the difference of coloration, the homogeneous armor is a bit rusty and the aluminum has pitting. Gaijin got that down pretty darn well!
Hey all, I found that there is a AAI penetrator from ADA058596. If we look at older documentation, it is mentioned that the AAI penetrator was named directly in the Darpa to Stoner document. I did some calculations. The muzzle penetration should be correct but I used AI to scale the original table to get the new numbers.
That is cool source you found, unfortunately you missread the penetrator diagram. The dimensions are not in inches but in calibers and here a caliber is 20.6mm.
So total length is only 316.8mm not 375.
Also the total weight is given as 1.38kg not 2.39kg.
I believe a caliber is 1 to 1 to inches here in the US
The 1.38kg is just the penetrator weight, not the projectile weight unless I’m missing something.
Here’s a picture of the supposed ammo measured in inches, the penetrator is there but the fins are sheared off
All the penetrator diagrams are normalized to the diameter of the individual projectile, unfortunately. And the weight is total, the paper this is from is concerned with flight dispersion of the projectile.
We can confirm this by looking at the XM579
The fin is given as 4.31 calibers, and a caliber is normalized to 1.39" for a total of 152mm which is the diameter of the XM150 gun launcher mounted in the MBT70 because the tail fin on the XM579 series acts as skids stabilizing the projectile in the barrel, so they are full bore:
The 14.34 number is the “Transverse mass moment of inertia” divided by the mass times the diameter squared. This is a way of describing “Aerodynamic jump” which is used to describe how a projectile changes trajectory after launch. So basically, it describes how stable the projectile is in flight.
