Writing for the Boston Globe today in 1952, science writer Michael Amrine shared the news that the hydrogen bomb—successfully tested for the first time on November 1 but not yet deployed—would allow the United States to conduct mass slaughter at the low low cost of $1 per person. Image
Amrine's column echoed comments made in a September 18, 1951, speech by Sen. Brien McMahon (D-Connecticut), chairman of the Joint Committee on Atomic Energy, noting the “startling fact” that using atomic bombs to deter and fight wars would be “hundreds of times cheaper than TNT.” Image
This was because one atomic bomb could destroy more “enemy war plants” than a single TNT bomb. McMahon then declared: “If we mass-produce this weapon, as we can, I solemnly say to the Senate that the cost of a single atomic bomb will become less than the cost of a single tank.”
Making A-bombs the “real backbone” of US military power by fully nuclearizing the army, navy, and air force “ought to mean fewer men under arms… [and] a major reduction in the tens of billions of dollars we would otherwise spend upon stacks and stacks of conventional armaments.”
Such savings were never realized, because nuclear weapons were very expensive to manufacture and maintain and actually required more manpower than conventional ones, and because during the Cold War the United States engaged in a nuclear arms race _and_ a conventional arms race.
Nevertheless, under these faulty assumptions, the US launched a rapid and massive nuclear buildup during the 1950s. At the time of McMahon's speech, the United States possessed 438 atomic bombs. Within ten years, the stockpile had increased to 22,229 atomic and hydrogen weapons. Image
A grateful tip of the hat to @wellerstein for the original clip.

Tonight in 1983, more than 100 million Americans saw multiple thermonuclear weapons destroy Lawrence, Kansas, in “The Day After” on ABC. A.C. Nielsen Co. reported that 62% of television sets that night were tuned in the film. I watched in my college dorm lounge. Where were you? ImageImage
Nothing can re-create the feeling of collectively watching that night—during rapidly escalating tensions with the Soviet Union while the Reagan administration openly advocated fighting and winning a nuclear war—but you can stream “The Day After” here:
Here is the parental advisory ABC ran before the film began regarding its depiction of a nuclear war: “The emotional impacts of these scenes may be unusually disturbing, and we are therefore recommending that very young children not be permitted to watch.”

At 8:50am today in 1979, data from a full-scale Soviet nuclear decapitation attack simulation running at NORAD were inexplicably sent to live warning displays there, at SAC, the NMCC, and the ANMCC at Site R, triggering a false alert and a ~6-minute threat assessment conference.
“… software simulating a Soviet missile attack [on] NORAD’s … computers ‘was inexplicably transferred into the regular warning display’ …. Indeed, NORAD's Commander-in-chief later acknowledged that the ‘precise mode of failure could not be replicated.’” nsarchive2.gwu.edu/nukevault/ebb3…
During this false alarm, NORAD activated all air defense interceptors and at least 10 planes took off, as did the president’s “doomsday plane.” Some air traffic controllers were ordered to immediately ground all commercial aircraft. At no point were POTUS or the SecDef notified.

Today in 1958, two miles south of Christmas Island (Kiritimati) in the Pacific Ocean, the UK conducted Round C (Operation Grapple X), its first successful H-bomb test. A Valiant bomber dropped an experimental device which exploded at ~7,382 feet with a yield of 1.8 Megatons.
Here is an excerpt from a documentary recounting the preparations for, execution, and aftermath of this test, including detailed recollections from some of the hundreds of servicemen who observed the explosion from the northern end of the island.
Here is some color footage of the early stages of the formation of Round C's mushroom cloud:

50 years ago today, the United States conducted its largest-ever underground nuclear test. A Spartan antiballistic missile carrying a W71 warhead was lowered into a 7-foot-wide, 5,873-foot-deep shaft beneath Amchitka Island, Alaska, and detonated. The yield was about 5 Megatons.
The test went ahead only hours after the Supreme Court refused requests to delay it over the Nixon administration’s failure to issue a comprehensive environmental impact statement. Instead, the court agreed with the admin’s claim any delay would upset the “balance of deterrence.”
Here is some remarkable official footage of the preparations for and results of that huge test. I have watched a lot of nuclear test films over the years, and even though Cannikin was entirely underground, this one never fails to send chills down my spine.

Today in 1962, the United States conducted Tightrope—its last fully atmospheric nuclear test—as part of Operation Fishbowl. A Nike Hercules SAM was fired 69,000 feet into the sky where its W31 warhead exploded with a reported yield of 10 kilotons 2 miles SSW of Johnston Island. ImageImageImageImage
Subsequent US tests that took place in the atmosphere included Operation Roller Coaster, four joint US-UK zero-yield plutonium dispersal safety tests (Double Tracks, Clean Slate I, Clean Slate II, and Clean Slate III) conducted at the Nevada Test Site from May 15 to June 9, 1963. ImageImageImageImage
There were also 4 Project Plowshare “peaceful nuclear explosion” excavation experiments in Nevada that deliberately breached the surface:
Palanquin—April 14, 1965; 4.3kt
Cabriolet—January 26, 1968; 2.3kt
Buggy—March 12, 1968; 5 simultaneous 1.08kt
Schooner—December 8, 1968; 30kt

Today in 1958—Election Day—a B-47 bomber carrying one unspecified sealed-pit thermonuclear gravity bomb became engulfed in flames on takeoff and crashed from 1,500 feet on private land about 4.5 miles SW of Dyess AFB, near Abilene, Texas. Three crewmen ejected, one was killed. ImageImage
An explosion of one or more of the assisted-takeoff rockets attached to the fuselage caused the fire. The bomb's conventional high explosives detonated in the crash—the B-47 was "literally blown to bits" per a local reporter—leaving a crater 35 ft. in diameter and 6 ft. deep. ImageImageImageImage
The thermonuclear secondary was damaged but recovered intact, as was the tritium reservoir, which was leaking. The USAF publicly insisted there was "no harmful contamination," although that wasn't true. It only fully cleaned up residual uranium and lead contamination in 2011. ImageImage
