Description

NOTE - This is a replacement image (and entry) in order to permanently remove the (disabled) downloadable model option of the older one.

Ported to OBJ from the game stock model included with Silent Hunter 4 (SH4) by Ubisoft.  Preview picture posed in XNALara XPS. NO MODEL DOWNLOAD.


The S-class submarines, also known at the time as sugar boats (S for sugar) and pig boats (because of their reputation of being old and dirty), was the very first full class of fleet submarines made for the United States Navy (USN) during the interwar period.  51 of them were commissioned into service from 1922 to 1925, and these were the submarines in which the American silent service sharpened its teeth during the middle interwar period.  These were bigger and had greater range than the World War I era R-boats,  They bore an uncanny resemblance to German U-boats because the conning tower design had been based on studies of surviving U-boats seized by the Allies after the war, and the German conning towers had been found to be superior to previous American ones for surfaced open sea operations.  Future USN admiral Hyman G. Rickover, the "father of the nuclear navy," credited his later obsession with high engineering standards to his service time aboard the pig boat S-48, once commenting rather acidly on their "faulty, sooty, and repellent engineering."  Despite their reputation their sheer numbers and ready availability meant that most would see service during World War II as possibly the oldest class of submarines to take part in that conflict.  They lacked the range of the USN's newer and more modern fleet boats, so they were used mostly for recon and supply duties, as well as coastal patrols.  Most were withdrawn from front line service by 1943 as more new fleet boats became available and were relegated to training duties.  All were scrapped after World War II.  To find out more about the USN's S-class submarine, follow the link below:

This is a straight port with no changes by me.


While I am no longer making my OBJ ports of Silent Hunter series models available for public download, you can get this yourself in one of two ways.  You can extract it piecemeal from the game data using the free SKWAS/s3ditor model utility and rebuild it in your preferred 3D modeling software, or you can rip it directly from the game after installing any necessary mods or mod packs noted above using any good 3D model ripper (3D Ripper DX or NinjaRipper recommended).

For non-profit, non-commercial use only.



NOTE - SH4's game stock model depicts a typical Group I Holland type S-boat, which was the most common and comprised the largest of the four groups eventually built in the S class as a whole.  These are often called the S-18 class in many civilian reference works because S-1 was the class prototype and S-18 was the first production boat per official USN records (long story there, go look it up), although technically per USN records they are the S class Group I.


TRIVIA - A S-boat is featured in the World War II movie U-571, during the early part of which which it operates as a disguised U-boat because of its uncanny likeness to one.


ASIDE - Because of their older design with its shorter torpedo tubes, all USN S class boats had to use older Mark 10 torpedoes instead of the longer (and longer ranged) Mark 14 issued to newer fleet boats at the start of World War II.   This includes the later Group III S boats I cover in a separate entry in my online C21VN gallery.  The Mark 14 torpedo would suffer from running too deep and from numerous multiple detonator failures (i.e. "duds") early in the war until the problem was finally resolved and fixed, whereas the older Mark 10s of the S boats never had this problem.  It is a significant enough factor that USN war gamers and fantasy fleet fans should take it into account and incorporate into their various projects.  To sum up:  all S class boats are older, slower, and have less range than the newer USN fleet boat classes; however, their older and shorter-ranged Mark 10 torpedoes are far more reliable will almost always work whereas the Mark 14 of the newer fleet boats will suffer from constant failures in use, with a "dud" ratio anywhere between 7:1 to 12:1 per official records (I suggest a 8:1 dud ratio or 6:1 if you're feeling generous) until November 1943, when fixed versions finally become available for USN newer fleet boat use and this problem goes away for good.
