Alterations and reversions 27 April 2005

• 1909: Did the War Office consider it? Or did they take one look and sling the idea in the bin?
• 1942 April: From what I have seen, their breathing sets were not modified from Davis (spelling!) Escape Sets but were specially made from scratch.
• 1942 June: The wording "which was based on a 21 inch diameter torpedo" implies that the chariots were made by taking parts from an ordinary submarine torpedo. Such a conversion is unlikely, because for one thing the motors are different. It is likelier that the Chariots were made from scratch.
• 1942 Oct 31: I see no reason to omit the detail "broke the fastening bolts".
• 1944 June 21: I see no reason to omit the detail "began to leak from its float tank".

To answer some points:-

0) Davis sets comes from the external links referenced.

1) Stripping the torpedo motor from a 21 inch torpedo and converting the hull fits in exactly with British mentality and the timescale involved.

2) the detail doesn't fit in with the terseness of the timeline and poses more questions. Which end failed? Chariot or trawler.

3) Where is the float tank? Is that buoyancy or trim? GraemeLeggett 07:58, 27 Apr 2005 (UTC)

4) Why are the X boats mentioned in this article in the timeline?GraemeLeggett 08:38, 27 Apr 2005 (UTC)

0) There are two ways that the frogman's sets could "come from" the Davis set:
(a) Made from new materials to a design which is a modified version of the Davis set's design.
(b) Made by taking physically existing Davis sets and changing parts of them.
1) Is there proof that this was done?, i.e. that the chariot's hull was cut from an existing ordinary torpedo?
2) The bolts broke. It is not stated how far along the bolt the break was. whether the fastener is caled part of the chariot or part of the trawler, is a matter of definition.
3) The same tanks served as buoyancy and trim, likely.
4) The X-boat operations occurred in the same series of frogman operations. Anthony Appleyard 17:03, 27 Apr 2005 (UTC)

• This link under heading In The Meantime looks somewhat unclear: "It is perhaps ironic that Siebe had in fact produced a bubble free rebreather system for autonomous diving called the Amphibian. It was based on the "Salvus" set but utilising a flexible counterlung for re-circulating oxygen" :: The Amphibian series is arranged completely different from a Salvus. I should know: I have had several dives with a Siebe Gorman Salvus. Also, the Salvus also has a flexible counterlung, so there is no purpose in the contrast expressed by the word "but". The paragraph contains little information, apart from a long description of how rebreather sets in general work. Anthony Appleyard.

I'll do what checking I can on the others. To return to X boats though, although both were part of the Submarine service they werer not manned torpedoes, and did not mix with the Chariot operations so far as I can tell. A brief mention that they were active at the same time would be enough, it also avoids duplication of the X craft article. GraemeLeggett 08:41, 28 Apr 2005 (UTC)

Restore two external links?

• German Seehund Midget Submarine WWII
• German Molch Midget Submarine WWII

03:46, 11 February 2006 202.156.6.54 (→External links) added these links
04:16, 11 February 2006 Ch'marr m (rv spam for modelling manufacturer) removed them.

I am tempted to restore these 2 links, as they both coontain good information, not only advertisement. Anthony Appleyard 19:25, 22 April 2006 (UTC)

What about the Japanese?

Didn't they train people to use manned torpedoes? I think i reember something about them being used for Kamikaze attacks. —Preceding unsigned comment added by 81.101.252.188 (talk) 22:20, 14 June 2009 (UTC)

GPS

I removed the reference to GPS, seeing as you can't receive GPS signals underwater. —Preceding unsigned comment added by 198.161.73.52 (talk) 21:40, 8 March 2010 (UTC)
