This new weapon, dubbed the B61-13, is expected to deliver around 360 kilotons of destructive power – 21 times the yield of the atomic bomb dropped on Hiroshima in 1945; it will be among the most powerful nukes in the U.S. arsenal.
The United States Air Force has successfully tested its first prototype hypersonic missile, the AGM-183A Air-launched Rapid Response Weapon, or ARRW.

The exact speed of the AGM-183A isn't known, although some have alleged it might reach Mach 20.

Newsweek 29.11.23: A new nuclear warhead has been approved and cleared for use in a variety of U.S. aircraft, notably the B-2A Spirit bomber. The warhead is part of continuing efforts to modernize the nation's nuclear stockpile for military use.
Spirit will be the first domestic combat aircraft to employ the B61-12 nuclear bomb, unveiled Monday as part of the 335-page unclassified Stockpile Stewardship and Management Plan (SSMP), a report for the 2024 fiscal year by the National Nuclear Security Administration (NNSA). The latter works within the Department of Energy (DOE) and designs, produces, delivers and certifies the nation's nuclear stockpile for military operation.
In October, the House of Representatives approved a resolution to increase defense spending in fiscal year 2024 by about $1.11 billion over the current fiscal year—including $19.114 billion for the continued modernization of the nation's nuclear weapons stockpile and infrastructure and $1.946 billion for naval warships.
Collectively, the world’s estimated 12,512 nuclear warheads belong to just nine countries. However, there are more than two dozen additional countries that participate in nuclear mission-related arrangements. While these countries do not have direct launch authority over any nuclear warheads, they play an important role in their storage, planning, delivery, and safety and use-control, and therefore merit a degree of scrutiny alongside their nuclear-armed peers.
Russia, the United States and China have all built new facilities and dug new tunnels at their nuclear test sites in recent years, satellite images obtained exclusively by CNN show, at a time when tensions between the three major nuclear powers have risen to their highest in decades.
Kärnvapenuppföljargruppen är en grupp av självständiga experter. Dess uppgift är att bedöma kärnvapnens roll och de risker som är förbundna med dem då Finland blir medlem i Nato samt att analysera hur Finland behandlar, tar ställning till och verkar i frågor som rör kärnvapen. Gruppens medlemmar är: Tarja Cronberg, Jaakko Ellisaari, Tytti Erästö,Kati Juva, Mika Kerttunen, Claus Montonen, Juha Pyykönen, Erkki Tuomioja, Katariina Simonen, Juha Vuori och Raimo Väyrynen.

"But even if in the film it’s the radicals who appear to have the first misgivings, it would be a mistake to think that it was the political right that approved of the bombing and only the Left who opposed it. The newspaper of the CPUSA, the Daily Worker, declared after the bombing that the Allies were lucky to have found struck “before the enemy can devise countermeasures.” The paper went on: “So let us not greet our atomic device with a shudder, but with the elation and admiration which the genius of man deserves.” Perhaps, one might counter, such calculation is to be expected from Stalinists. Yet the non-Stalinist but still progressive magazines The Nation and the New Republic felt little differently. Nation editor Freda Kirchwey wrote at the time: “The suffering, the wholesale slaughter it entailed, have been outweighed by its spectacular success.”
Few escaped the twentieth century with their honor intact, although it’s noteworthy that it was the more religious side of the liberal-left who was the first to mark their disquiet at Hiroshima and Nagasaki. As historian Paul Boller noted, it was in fact the social gospel–oriented Catholic weekly Commonweal and its protestant counterpart Christian Century that straight out of the gate argued that the bombings had destroyed the nation’s moral position in the world.

sista stycket: Det finns återigen en antydan i Nolans film. Det ursprungliga löftet om gränslös frigörelse från dominans - vare sig från andra människor eller från resten av naturen - som gavs när modernitetens tre världar förenades under 1900-talets första år, har inte svikits så mycket som det har lämnats ouppfyllt. Det som Oppie och Rabi och resten av efterkrigstidens progressiva motståndare till kärnvapenspridning strävade efter - en internationalistisk egalitarism utan CPUSA:s dogmer och falska vissheter, där hela världen drog nytta av kärnkraften men kärnvapen var förbjudna - förblir målet.
China’s Global Security Initiative should be carefully considered and discussed. Even a brief survey of world events indicates the pressing need for a different set of security arrangements from those currently pursued by the US and NATO allies.
