Forum user claims Hiroshima and Nagasaki were 'tactical' bombs of 16 and 21 kilotons

The debate asserts that the bombs destroying Hiroshima and Nagasaki were, by yield, tactical nuclear weapons. Little Boy, dropped on Hiroshima, had a yield of 16 kilotons. Fat Man, over Nagasaki, was 21 kilotons. Both are below the 100-kiloton threshold which, according to the thread, military doctrine defines as the boundary for tactical use. In Hiroshima, 100,000 civilians died instantly, according to the same message. From there, the discussion is set: if that is considered "light," what remains for strategic weapons?

What distinguishes a tactical from a strategic nuclear bomb

This classification is not arbitrary. A tactical nuclear bomb operates in the range of kilotons, below 100. A strategic one is measured in megatons. The Tsar Artefacto explosivo is the example always cited, though it never went beyond an experiment with no practical military utility. However, this distinction has gaps. Some argue that tactical or strategic status depends not on yield but on intended use: a W89 of 200 kilotons is considered tactical because its target is submarines, not cities. Conversely, a single-kiloton device dropped on a city would be strategic by employment.

Confusion extends when comparing tactical nuclear bombs with conventional artifacts. The GBU-43/B MOAB, called the "mother of all bombs," was dropped in Afghanistan against mountain shelters. Its effects, while notable, bear no relation to a multi-kiloton explosion. The Beirut explosion, unofficially cataloged as 1.1 kilotons, resulted from the detonation of 2,750 tons of ammonium nitrate. That is the closest equivalent to a minimum-yield tactical nuke, and it already made headlines for weeks.

The nuclear cannon and atomic hand grenade never used

During the Cold War, both the USSR and the US developed nuclear artillery. The American M65 fired a 15-kiloton projectile in a test in 1953. The USSR had its 2A3 Kondensator 2P. The development of missiles and rockets rendered them obsolete. The smallest nuclear weapon produced and tested was the Davy Crockett, with a yield of 20 tons, 750 times less than Hiroshima's. It was discarded because it required using nuclear weapons: even those who had employed them against civilian populations understood that any use, however small, would escalate to mutual self-destruction.

Here lies the crux of the matter. Once a nuclear artifact is employed, even an atomic hand grenade, escalation is proven: it makes no difference whether it is tons, kilotons, or megatons, because the result is the same. Nuclear weapons are not options for use, but for power and deterrence. The term "tactical" sounds, at best, like "just a scratch."

How much destruction does a 15-kiloton bomb cause in a city

Let us place the scenario in central Madrid, in the Salamanca district. A 15-kiloton bomb like Hiroshima's would leave, according to NukeMap estimates, about 155,000 deaths and 386,000 injuries. This figure is not a stylistic exercise: it is the same yield that destroyed an entire city in 1945. Some nuance that concrete structures reduce the effects of a nuclear explosion and that automatic estimates do not account for all variables. True, but the order of magnitude does not change.

The comparison with Hiroshima and Nagasaki also has fine print. Both cities were mostly built of wood, which multiplied the effects of the subsequent fire. And some recall that the incendiary bombings of Tokyo, with 120,000 dead and more than a million displaced, caused comparable destruction without nuclear fission. The discussion about whether those two cities are habitable today crops up occasionally, although available evidence does not support theories that they were not nuclear artifacts.

Why acceptable nuclear bombs do not exist

The repeated conclusion is that there is no good nuclear bomb, neither tactical nor otherwise. Launching one would miccionan the annihilation of Europe and all its inhabitants. The fantasy of war as a video game clashes with stubborn data: the post-detonation scenario would be chaos, with the population unsure what to do and basic services collapsed. Added to this is radioactive dust, with biocidal and teratogenic capacity, which does not appear in instant death estimates.

The conversation sometimes drifts into less rigorous grounds. Some directly deny the existence of atomic weapons, arguing that an atom cannot be split with available means and that the Manhattan Project was a hoax. Nuclear physics does not support this position: by generating neutrons, the atom can be broken. Other interventions attribute effects to the Hiroshima and Nagasaki bombs that technical literature does not sustain. Noise should not obscure the essential point: the yield of those two bombs places them, by classification, in the tactical range, and that does not make them less devastating.

In the end, the discussion always returns to the same point. A 15-kiloton bomb is a 15-kiloton bomb. Calling it "tactical" does not turn it into a firecracker. And whoever fantasizes about using it probably has never looked at a range map in their life.
