What's a "ton"? Gene Nygaard 23:01, 30 Dec 2004 (UTC)
I deleted "total 915 tons". I've never heard "total tons" in ref a sub. If it's surfaced full load, say so. (I'd question that, too; the typically quoted number is around 750.) Might also clarify if it's standard tons, per London Naval Conference measurements (as often used in American sources), or a typical German figure. Trekphiler 11:16, 20 October 2006 (UTC)
Somebody needs to check those range figures. They don't equate nautical miles & km, & most navies quote them as "x miles @ x knots" as meaning "nm", not "statute miles".... Also, they don't tally completely with the source I've got--but they do accord close, & my source lists them as nm.... Trekphiler 11:37 & 11:42, 20 October 2006 (UTC)
I don't see any mention of the introduction of Metox ("Biscay Cross") radar warning reciever. Also, it occurs to me it might be worth mentioning the TT are 55cm. Trekphiler 11:55, 20 October 2006 (UTC)
I added the crush depth values, which is the depth at which a Type VII would most likely be crushed. This was not an exact value but depended from boat to boat. The data comes from a good source, a former (lady) spy of the French resisitance which I knew very well. Meswiss.
"According to German sources only two aircraft had been shot down by U-flaks in six missions (three by U-441, one each by U-256, U-621, and U-953)." - Can anyone clear this up? -- Bryson 19:54, 2 February 2007 (UTC)
I moved all the general characteristics to the infobox, but looking at it it kinda skews the whole article layout - maybe it's better to keep a minimalistic infobox instead? Maybe just list the characteristics of the VIIC or something in the infobox? Anywho, if somebody decides the article looks worse now, feel free to revert back to a previous version - or tell me how you want it and I'll change it. Abel29a 14:13, 7 April 2007 (UTC)

The description of the VIID states that it was
a longer version of the VIIC with three banks of five vertical tubes just aft of the conning tower
. I think that might be confusing. I would rather write that there were
five vertical shafts, with three mines each
. The problem with the word tube, is that it sounds like a torpedo tube. Also, the 3 banks, implies there were 15 tubes total, when I think the original author was trying to explain there were three mines in each shaft.
I'm not an expert on U-boats, so I do not want to edit the original article. Perhaps someone who knows more could check my assertion and put in any corrections as necessary. Thankyou. —Preceding unsigned comment added by 130.246.132.26 ( talk) 12:40, 23 January 2009 (UTC)
U-977 and U-978 are missing in the discussion of Type VII U-boots. Were they VIIC or VIIC/41, or another version? They were both commissioned in 1943. -- Bejnar ( talk) 01:29, 14 January 2010 (UTC)

I changed the conversion in the infobox from LT->t to t->LT. German measurements are metric and so are the figures given in most publications. Strangely there are other figures floating around (761 surfaced and 865 submerged respectively) which do not make any sense to me as they do not seem to correspond to long tons or metric tons either, the only two units for warships used to my knowledge. -- FJS15 ( talk) 07:19, 5 June 2011 (UTC)
The submarine is easily visible at Google Earth coordinates: 54 24' 45"N 10 13' 44"E . I don't know how to put those coordinates into the main page to make them map-clickable. 58.168.52.243 ( talk) 09:04, 7 September 2012 (UTC)
Hi, I'm thinking of turning this file
Commons:file:SRH009-p58.jpg into a svg one. My problem is that the quality of the file is bad, I have found one that is bigger but it's still very hard to see all the details.
So my questions is;
- Do anyone here know of a better source image?
- If we can't find a better source image, does anyone here have the detail knowledge and can help me correcting my drafts?
Please ping me, thanks. --

The "inflation adjusted" figures are nonsense. They don't take account that a dollar today buys technical sophistication undreamt of in the '40s, nor do they take account that wage rates have also changed, so much that a month's pay then wouldn't buy as much as a month's now, even in constant dollars. In short, the number is misleading, not just uninformative, & WP standard or no, shouldn't be used. TREKphiler any time you're ready, Uhura 05:06, 14 January 2018 (UTC)

I see two problems with this. One, the note: "in this context 'double-acting' means the same device was capable of acting as a motor, powered by battery and turning the propeller; or as a generator powered by an engine, charging the battery." It's been a while since I had my rotating machines class in engineering school and I no longer have my textbook, but a "double-acting" machine is one that has the shaft extended out both ends, so it can drive (or be driven by) other machines on both ends. In this case that would be the diesel engine on one end, and the shaft and screws on the other end.
Two, why does "double-acting" link to Motor–generator? A motor-generator is a device that has both a motor and a generator on a single shaft, often sharing a single set of field coils. The electric motor on a U-boat is certainly not a motor-generator. GA-RT-22 ( talk) 15:36, 26 August 2022 (UTC)
