In the files for vessels all the US subs have a "false" flag under anechoic coating. Even the Los Angeles class.

Is this a mistake?

Were they in wide use in the time period?

I thought they were added to the 688 flt1 in '85 or '86 but I am not an expert on this.

I'm not sure either to be honest and my Google-fu is failing me...

From what I've seen, I believe the Russians added anechoic tiles before the Americans. I can't remember where I've seen that, though.

Wikipedia claims they did in the 70's and that one US sub got it in the 80's as the first one, but the article is very sparse on detail so that doesn't really help us. :(

Well it is not on the United States submarines in the game. This would explain why the Russian active sonar is so damn affective at long ranges.

hi,

according to Clancy's book:

https://books.google.com/books?id=aw4PwvuZ1SMC&pg=PA49&lpg=PA49&dq=los+angeles+flight+ii+anechoic+coating&source=bl&ots=LagEleu4CS&sig=gdXGhAoT17O0fBo_IgOfBjBeDZw&hl=zh-CN&sa=X&ved=0ahUKEwi8h-Sf9LDUAhUKf7wKHWpNBeUQ6AEINzAC#v=onepage&q=los%20angeles%20flight%20ii%20anechoic%20coating&f=false

flight II was the first to receive the coating and they were then back fitted. considering the 1984 time frame the game setting FALSE seems correct.

ofc i'm no naval expert and i dunno how credible is Clancy on technical details vs say official navy documents that 6 more hours of googling may or may not dig up!!

Hi Julhelm,

well it...

heck IHMO it actually doesn't matter since you guys enabled modding and the value is moddable! If i think it should, i change it to TRUE, and if he thinks it shouldn't, he set it to FALSE. everyone is happy:)

Nipplespanner seems to think they were added to FLT II subs at the keel start and FLT I Los Angeles class after the fact. I cannot come up with a clear answer myself....http://www.subsim.com/radioroom/showpost.php?p=2489560&postcount=2 (http://www.subsim.com/radioroom/showpost.php?p=2489560&postcount=2) All of this varies with Wiki which states USS Batfish (Sturgeon class) was the first to have the tiles in 1980: https://en.wikipedia.org/wiki/Anechoic_tile (https://en.wikipedia.org/wiki/Anechoic_tile) :hmmm: http://www.dtic.mil/dtic/tr/fulltext/u2/d020262.pdf (http://www.dtic.mil/dtic/tr/fulltext/u2/d020262.pdf)

USS Batfish (SSN-681) and USS Olympia (SSN-717) were the two test platforms in the middle 80's. The boats were not built in hull number order.
If I remember correctly, somewhere in flight 2 is when the tiles were added in new construction. All other boats (637's included) were backfitted.

There were two main flights of 637's (not including the three specials) and FOUR distinct flights of 688. (Wikipedia is incorrect)

Flight 1 - 688-699 (upgraded to flight 2 specs at first DMP)
Flight 2 - 700-718
Flight 3 - 719-750 (First VLS)
Flight 4 - 751-773 (also called 688I)

Served on SSN-700, SSN-670 and SSN-723
