Talk:British 21-inch torpedo

Out of spec
This page says the 21" was introduced to subs with the O-boats in 1927. This page says the last two M-boats had 21" tubes. They can't both be right.... TREK philer  any time you're ready, Uhura  14:34, 30 October 2013 (UTC)


 * Possibly the O-class had them as designed, M3 had them when rebuilt in 1927 an afterthought, M4 was going to have them as an experiment but as it was never built... Definitely clarification needed. GraemeLeggett (talk) 16:49, 30 October 2013 (UTC)
 * That was my thought: the later M-boats completed, or rebuilt, with 21". I don't have the sources to confirm, tho, so if anybody does...  TREK philer   any time you're ready, Uhura  02:36, 31 October 2013 (UTC)

"only the second sinking of a surface ship by any submarine since the end of WWII"
I added a citation needed tag. Could also do with tightening the language as if you include accidental sinkings of fishing craft there are more. Springnuts (talk) 15:31, 20 December 2014 (UTC)
 * It now says "This is the only sinking of a surface ship by a nuclear-powered submarine in wartime". The Falklands conflict was not a declared war. — Preceding unsigned comment added by 162.251.232.55 (talk) 00:07, 24 June 2018 (UTC)

21" (53.3 cm) Mark IX and IX**
Where 21" (53.3 cm) Mark IX and IX**?--Inctructor (talk) 23:35, 21 September 2015 (UTC)

Mark VIII**
In the reference for "Mark VIII**" the ** is never explained

Inconsistency in article
Spec block states Mark IV of 1912 had "burner cycle" power. Portion on Mark VIII of 1927 states it was first british burner cycle torpedo. This not consistent -- cant both be right. — Preceding unsigned comment added by Skb999 (talk • contribs) 09:04, 24 August 2016 (UTC)
