You seem to misunderstand me, I’m saying there is no backing layer (spall liner), go through the photos I posted.
I didn’t comment on that, and im not here to judge wether a vehicle has a spall liner based on some images
Edit: i commented on backing layer not being a spall liner
…you mean the composite armor that is between the metal you posted images of? The composite armor modules are where the spall liner is located. The references to the Abrams program in the integrated composite armor would indicate that they got their information from said program.
You know, the same tank being described as incorporating a spall lining in multiple documents now?
There is only one source that says there are spall liners inside M1s and its an editorial error.
Let’s humor you and assume its talking about the “monkey model” M1s.
Opps. No spall liners there either.

Then what are you looking for? Because the only DTIC source says the M1 Abrams does not have a spall liner, normally that would be good enough but I’m trying to add more since I was already researching this way before so I already compiled a list. The only other DTIC study talks about the XM1

God youre dense
What part do you not understand that you CANNOT see it. Because you cant see air or gravity is it not there?
Post the whole doc
Im looking for dumb statements like “backing layer isnt a spall liner”
I don’t pretend to be on topic, i like my forum threads like my trains, derailed on interesting subjects
Please note that this document can be applicable only to pre-1996 abrams.
Really? Now you are claiming that the spall liners are invisible?
LOL
I guess you got us there.
I give up. Yes, the M1 has magical invisible unobtainium armor on the insides.
Blatantly false. These DTIC sources say the Abrams have spall liners.:
https://apps.dtic.mil/sti/pdfs/ADA065838.pdf
This DTIC source references the Abrams program while showing improved methods for constructing integral composite armor modules with internal spall lining.:
So we have at least 3, including one that shows the material working. Despite the design being something you claim is impossible.
Thats the XM1 document, also the “references” arent referneces, they’re the number of copies given out to various departments.
Second one was still for the Crusader SPG program from the early 2000s.
The XM1 was a part of the Abrams program.
The document you are citing isn’t even an official Army document, though. Look who prepared it. Not even the Army Research Lab. XD
Gee, you think the Abrams program would be interested in improvements to their integral composite armor design, or seeing the results of the information they provided and how it was being represented?
A lot of cost-cutting measures were made before the M1 went into production. It was originally going to get the much better M-60A3 TTS thermal sight, but a cheaper one was installed. etc. I guess spall liners were also chopped.
What? Ok last call, GHPC discord so you can talk to more people or I move on.
Layers exist you know
No, you just keep ignoring what everyone is saying though, its integrated, not some cheap fabric dangling down like a car dashboard rug
For onions. It defeats the purpose of a “spall liner” for it to not be on the outside (inside?) to catch the spall.
