Small point: People throw around the "kt" label when it means very different things in context. Nuclear weapons are generally measured in TNT equivalent, the hiroshima bomb being roughly 15,000 tonnes equivalent (15kt). This is so common that "kt" has blurred in the mind and we forget that different explosives can be considerably more or less powerful than their TNT equivalent.

The 2020 Beirut explosion involved 2,750 tonnes of ammonium nitrite which exploded with a force equivalent to 1,100 tonnes of TNT.

The SS Richard Montgomery sank with 1,400 tonnes of explosives, of a variety of types, some of which could be more powerful than TNT.
