PFC James (LURCH) Janota6959379<div class="images-v2-count-0"></div>I was watching a documentary about WWII and the different ships and they said the bulkheads were 17” thick. I took out a tape measure to show him what that looked like and he made the comment, that was thicker than our house walls. So he and I just wanted to know if modern day ships are that thick?Are the bulkheads still 17” thick on today’s ships as they were in WWII?2021-05-08T04:46:57-04:00PFC James (LURCH) Janota6959379<div class="images-v2-count-0"></div>I was watching a documentary about WWII and the different ships and they said the bulkheads were 17” thick.

But I would guess that this type of specification would go danger close to OPSEC violations. Not the type of thing to discuss on an open forum (even if it probably *is* unclassified).<br /><br />Not in the Navy, not sure how "public" that info is. Just looking at it from an adversary POV.Response by SFC Casey O'Mally made May 8 at 2021 1:13 PM2021-05-08T13:13:23-04:002021-05-08T13:13:23-04:00MAJ Ken Landgren6960341<div class="images-v2-count-0"></div>Would you like to read a narrative of how important the US Navy was in our quest to defeat Japan?Response by MAJ Ken Landgren made May 8 at 2021 2:21 PM2021-05-08T14:21:25-04:002021-05-08T14:21:25-04:00LTC Jason Mackay6960343<div class="images-v2-count-0"></div>Would say this specification is not the same as many US Navy vessels have aluminum hulls.

That has a lot to do with materials used, weapons used, and naval tactics as a whole. If you compare something like the USS Alabama to a modern littoral you can see how tech has evolved. We don't use 16 inch guns anymore so ships don't need to be so large to support that weapon system.Response by SSgt Christophe Murphy made May 8 at 2021 3:02 PM2021-05-08T15:02:20-04:002021-05-08T15:02:20-04:00Maj John Bell6960443<div class="images-v2-count-0"></div>You are probably referring to the armor plates that make up the hull, particularly at or near the water line. Bulkheads are something entirely different.<br /><br />A bulkhead is essentially any wall that divides two or more compartments. They can be steel or aluminum, thick or thin. A powder magazine may have vented blast walls of case hardened steel in excess of 16 inches thick. <br /><br />Officer's country, above the waterline, the compartment walls will normally be made of stiffened sheet metal less than 1/8" thick.<br /><br />It is all about the contents of the compartment and the stability/seakeeping ability of the hull formResponse by Maj John Bell made May 8 at 2021 3:59 PM2021-05-08T15:59:55-04:002021-05-08T15:59:55-04:00CWO3 Private RallyPoint Member6960517<div class="images-v2-count-0"></div>That's how we had 50,000 ton battleships.Response by CWO3 Private RallyPoint Member made May 8 at 2021 4:40 PM2021-05-08T16:40:39-04:002021-05-08T16:40:39-04:00SGT Private RallyPoint Member6960662<div class="images-v2-count-0"></div>Not today ISIS.Response by SGT Private RallyPoint Member made May 8 at 2021 5:48 PM2021-05-08T17:48:55-04:002021-05-08T17:48:55-04:002021-05-08T04:46:57-04:00
