105mm HEAT pened turret side ?

interesting design changes in gun rotor, from M1 to IPM1(PV11 XM1 seems already had IPM1 type of rotor) and to M1A1
 
IPM1 had similar structure of rotor as M1A1, but lesser thickness

"Between Jan and Dec 2001, 45 Abrams tanks suffered fires during training, some were damaged, some were destroyed entirely. Over the tank's life at that point (22 yrs), there had been >600 fires - that's almost 10% of the fleet had..."

An examination of data from peacetime fire incidents experienced by ground vehicles reveals several facets pertinent to this study. In Table 1, peacetime fire incident data for the M1/M1A1 tank for the years 1988, 1989, 1990 and the fires six months of 1991 have been summarized. These data show that the AFES system was only activated 71 percent of the time for M1/M1A1 fires and was adequate to extinguish the fire by itself only 34 percent of the time.
 
 
so how many tanks actually burned ?

engine hatches, same thing, ceramic on FRP, how they planing NOT to damage ceramic tiles during daily maintenance of tank i have no idea

the final version of Arjun's calculations, all the thicknesses of the plates correspond to the real ones according to the nomenclature of the armor plates (those that existed), the dimensions of the special armor of the turret may not be accurate because there is nothing to check them with, 2 fuel tanks inside the engine bay have been added to the diagram which were not previously visible, more accurate estimates only possible if someone undertakes to build 3D...
