So it’s worth noting that “Tactical” and “Strategic” nuclear weapons are a vague comparison. There’s a saying I’ve heard that what defined a nuclear weapon as “tactical” in the Cold War was if it detonated on German territory or not. Certainly a lot of “tactical” warheads had/have more power than the very strategic pair of WWII bombs.

Now you can just say “use” and that’s a fair definition. But I like to define it as range of the delivery system. So even if say, the legendary “Atomic Annie” cannon’s shell is in the same yield ballpark as the Little Boy, its short range qualifies it as a “tactical” system while a bomb carried by a long-range B-29 or similar plane counts as “strategic”.

It’s as good a distinction as any.
