Bombs and rockets

I recently saw the documentary Zero Days about state-sponsored cyber warfare in general and the Stuxnet attack against Iran’s enrichment facility at Natanz in particular. The documentary doesn’t really contain any new information for people who follow the news in this field, but it’s well put together and has some compelling interviews. A couple of […]

So much confusion, so much paranoia, so many good intentions, so much hard work, technical genius, cynicism, manipulation, buckpassing, buckpocketing, argument, grandstanding, risk-taking, calculation, theorizing, goodwill and bad, rhetoric and hypocrisy, so much desperation, all point to something intractable behind the problem of how to deploy sufficient and appropriate nuclear arms to protect one’s nation […]

I have read quite a few books that pertain to Israel’s development of nuclear weapons at Dimona. It’s of historical interest for many reasons, ranging from the support states notionally opposed to nuclear proliferation actually providing assistance to foreign weapon programs, to whistleblower history, the geopolitics of the Middle East, and the details of capabilities […]

I think it has been plausibly demonstrated that people who witness the violent and traumatic death of other people may experience adverse psychological consequences as a result. It’s hard to interpret the significance of that in the present era, or more so in the case of my own life. Ignoring early childhood, I don’t think […]

From a number of perspectives, I find YouTube videos which include demonstrations of Trident D5 missile launches from American Ohio-class ballistic missile submarines highly interesting: I find the first of the three clips (USS Nebraska) especially intriguing because of the highly stylized, almost theatrical language of the exchange between the bridge officers authenticating the emergency […]

This remarkable interview with Robert Hill, Former Chief Naval Engineer Officer of the Royal Navy, discusses the peculiarities of Hyman Rickover, including some very revealing stories, as well as Rickover’s role in developing the civilian reactor at Shippingport. The description of Rickover’s interaction with the chairman of Rolls Royce is quite amusing, though it also […]

There were large expanses of the globe where spying, or even a pretence of it, seemed an unproductive activity because they were strategically irrelevant. When a question was raised in London about running some double agents out of Canada, the responsible MI5 officer — Cyril Mills, of the well-known British circus-owning family — demurred. Even […]

Spring brought an increasing flow of decrypts about Wehrmacht operations in the Eastern Mediterranean. Senior officers strove to streamline the transfer of information from Bletchley to battlefields, so that material reached commanders in real time. One of the most significant intercepts, detailing German plans for the May 1941 invasion of Crete, reported ‘probable date of […]

Hut 8 [of Bletchley Park] now had enough information to read some U-boat signals, but the seizure which opened the traffic to fluent decryption was the fruit of chance and high courage, rather than of design. On 9 May 1941 a convoy escort group attacked and forced to the surface Julius Lempe’s U-110. A boarding […]
