Rules:

Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Iranian warship rolls over in port, could be out of action for six months (www.cnn.com)

One of Iran’s newest warships capsized in port over the weekend while undergoing repairs, an incident that could damage key warfighting systems and put the ship out of commission for up to half a year, a naval analyst said.

The 311-foot-long frigate Sahand was at a dock in the port of Bandar Abbas when it “lost its balance” after water leaked into its tanks, according to a report from the state-run Islamic Republic News Agency (IRNA).

A photo from the semi-official Tasnim News Agency showed the warship, with a displacement of about 2,000 tons, resting on its left side in the Bandar Abbas port.

The ship, which Tasnim said entered service in December 2018, is one of the bigger vessels in Iran’s fleet, equipped with antiship cruise missiles and an electronic warfare system.

There are multiple incidents that kind of fit, but I think you are talking about this one: Wiki article

Information declassified since 2013 has shown that one of the bombs was judged by nuclear weapons engineers at the time to have been only one safety switch away from detonation, and that it was "credible" to imagine conditions under which it could have detonated.

That's the one

Parker F. Jones, a supervisor at Sandia, concluded in a reassessment of the accident in 1969 that "one simple, dynamo-technology, low voltage switch stood between the United States and a major catastrophe" He further suggested that it would be "credible" to imagine that in the process of such an accident, an electrical short could cause the Arm/Safe Switch to switch into the "Arm" mode, which, had it happened during the Goldsboro accident, could have resulted in a multi-megaton detonation.

Bill Stevens, a nuclear weapon safety engineer at Sandia, gave the following assessment in an internal documentary film produced by Sandia in 2010: "Some people can say, 'hey, the bomb worked exactly like designed.' Others can say, 'all but one switch operated, and that one switch prevented the nuclear detonation.'"[34]

Charlie Burks, another nuclear weapons systems engineer for Sandia, also added: "Unfortunately, there have been thirty-some incidents where the ready/safe switch was operated inadvertently. We're fortunate that the weapons involved at Goldsboro were not suffering from that same malady."[35]

The bomb was about 250 times more powerful than the Hiroshima bomb. I don't know exactly how it works, but if it's simple multiplication, then you could say that everything for 480 miles in any direction would have been more or less destroyed.
