The new range of nuclear bombs, called the B61-13, is being implemented to upgrade America's nuclear stockpile, and will be a new variant of the B61 gravity bomb, first produced in the 1960s during the Cold War.
On October 27, the Department of Defense sent out a press release, saying the new weapons will "assure our ability to achieve deterrence and other objectives" whilst having the "modern safety, security, and accuracy features" of the B61-12, a variant introduced under the Obama administration.
Officials said the new range would roughly have the same yield as the B61-7, which had about 23 times the explosive power of the nuclear bomb dropped on Hiroshima, Japan.
Due to the similarities between the B61-7 and B61-13, the impact should be comparable.
The "nuke map" produces four tiers of damage. Anything inside the yellow area "is effectively vaporised". The second grey tier is where "most residential buildings collapse, injuries are universal, fatalities are widespread." The orange area show where there is an "100% probability for 3rd degree burns" which "can cause severe scarring or disablement, and can requite amputation."
Finally, the fainter grey circle shows where "glass windows can be expected to break" causing "many injuries in a surrounding population.
Using the model, we looked at the impact the nuclear weapon would have on European cities.
In London, anyone near Big Ben would immediately be wiped out by the bomb. Clapham, Camden Town, and Chelsea would suffer large fatalities, burnt buildings, and mass injuries. The model predicted over half a million fatalities, over one and a half million injuries.

The Eiffel Tower would immediately be destroyed in the B61-13/7 was dropped on Paris today and would face almost double the amount of casualties than London. The most fatalities out of any European city modelled of over 2 million.

In Madrid, even the airport would face injuries such as third-degree burns and fatalities would rack up to over 600,000.

Impact would go as far as Prestonpans if a bomb was dropped on Edinburgh, with estimated fatalities reaching just under 200,000.

If a bomb were to be dropped on Rome, mass fatalities would reach the Vatican City and almost a million civilians would suffer injuries.
