I'll review this article shortly.--Tomobe03 (talk) 10:09, 23 September 2013 (UTC)


 * There are few duplicate links in the article which should be removed per WP:OVERLINK. Those are: nuclear fission (in the lead), cordite, and Trinity nuclear test.
 * ✅ Removed duplicated links. Hawkeye7 (talk) 12:58, 30 September 2013 (UTC)
 * Checklinks reports no problems with external links (no action required)
 * There are no duplicate links in the article (no action required)
 * All images are properly licenced and have suitable captions (no action required)
 * The article is stable (no action required)
 * Article prose is fully referenced (no action required)
 * At the image of the plugs, the caption says "The plug on the left may have been used in the bomb which was dropped on Hiroshima." Is there a source for that? Maybe a label at the exhibit?
 * I've asked Nick. They definitely are Little Boy arming plugs. Removed the claim about Hiroshima for now. Hawkeye7 (talk) 12:58, 30 September 2013 (UTC)
 * In It consisted of a stack of 9 uranium rings, each 6.25-inch (159 mm) with a 4-inch (100 mm) bore of a total length of 7 inches (180 mm), pressed together into the front end of a thin-walled projectile 413 millimetres (16.25 in) long. I'm not quite sure what the 6.25 in measurement refers to. I assume it is the diameter, but I simply cannot tell.
 * ✅ Correct. Re-worded to: "It consisted of a stack of 9 uranium rings, each 6.25 in in diameter with a 4 in bore in the center, and a total length of 7 in" Hawkeye7 (talk) 12:58, 30 September 2013 (UTC)
 * Name Little Boy appears 35 times in the article, 8 times enclosed in quotes and 27 times without them. I could not deduce a rule for those though. Should those be made more consistent perhaps?
 * ✅ Removed the quotes Hawkeye7 (talk) 12:58, 30 September 2013 (UTC)
 * There is also a mix of date formats, eg. "July 23, 1945" and "29 July" - please select one and apply it consistently.
 * ✅ Corrected. Hawkeye7 (talk) 12:58, 30 September 2013 (UTC)
 * If Morris R. Jeppson was Second Lieutenant at the time of the bombing, add his rank to the first instance of the name.
 * ✅ Done. Hawkeye7 (talk) 12:58, 30 September 2013 (UTC)
 * Reading the article I got an impression that a total of 32 bombs were made: 1 dropped on Hiroshima, 6 made in Sandia and 25 by the Bureau of Ordnance, yet the infobox states 1 was built. Were the 31 made in the post-war period somehow incomplete or different, or should the infobox figure be updated?
 * They were incomplete. They were assemblies, but there were no uranium cores. When we talk about nuclear weapons in the 1940s and 1950s, we are really talking about bomb parts rather than bombs. They had to be assembled, because the lead-acid car batteries that powered the electronics would go flat after a few days, and the polonium in the detonators had a half life of only 138 days. (initially it was thought that this meant that they had a shelf life of four months, but Operation Sandstone in 1948 showed that older initiators could still be effective.) For legal, safety and security reasons, the cores were stored separate from the assemblies. On reflection, I have changed the number built to 32. Hawkeye7 (talk) 12:58, 30 September 2013 (UTC)

Great article, I thoroughly enjoyed reading and reviewing it.--Tomobe03 (talk) 11:55, 30 September 2013 (UTC)
 * All points addressed. I always like to hear that someone enjoyed reading an article. Hawkeye7 (talk) 12:58, 30 September 2013 (UTC)

Physical effects of the bomb
The sudden reappearance of this section is explained in my discussion with Hawkeye7: User_talk:Hawkeye7 In the next few days I will redo that section's footnotes in the sfn style and fix some awkward wording. (I do not want to jeopordize the article's GA status.) HowardMorland (talk) 04:38, 5 November 2013 (UTC)
