Sadly, I cannot find those comment again, and IIRC it only mentioned the computation being done, but not how. Obviously, it's very rough, but it helped him to debunk the 60 knots Ohios and stuff like that, using a best case scenario for power, and public data for displacement. I remember /u/Vepr157 discussing this on reddit, on how they could provide an upper bound on reactor power using the size of the hull section housing the reactor, and public data on the power density of PWR reactors. īut then I wondered how those public estimate using OSINT data are actually made. I feel like that's unlikely, because the alfas barely did more than 43 with around the same power, for half the displacement / A much smaller wetted surface / (i'm getting more speculative / unsure here) a more efficient hull / sail form (blended sail, body of revolution hull form). Someone on reddit is telling me that SSN21 could do more than 47 knots. I don't own the book, so I can't check, but I wonder how this estimation was computed. The source is Polmar, Cold War submarines, so that's quite trustworthy IMO. The wikipedia article for the Los Angeles class mentions that unclassified estimate of the LA class top speed are around 30 to 33 knots. ![]() I am posting this as suggested by /u/Vepr157, so that everybody can see this, hopefully it will be interesting. ![]() USS Razorback - SS 394 - Little Rock AR.Veteran's Crisis Lineġ-80 or text "start" to 741-741 Museum Submarines If you don't have any documents you can request a board to verify knowledge.a photo of you in uniform showing pins (Dolphins).Official awards showing your qualification. ![]() Message your verification info to The Chief Why Submarines are called boats and not called ships - /u/Vepr157 We are the subreddit dedicated to every machine under the water.
