What Scale were the Nukes used in the Series?
It seems to me that most of the nukes we see are tactical, smaller warheads on the order of 1-100 kilotons.
In the opening miniseries we see with the nuking of Caprica that there are multiple small explosions feeding larger mushroom clouds. Over targeting like this is a common military tactic especially on larger geographic targets like entire cities.
We see Galactica take a direct nuclear hit early on and at least once again during the course of the series. That suggest smaller warheads, designed to take out targets with their radiation as much as with their explosive force. After all, nukes in space don't have a medium like air to carry a shockwave. Galactica's armor and double hull likely took the brunt of those attacks, and the amazing part is that they held.
The attack that seems to do the most damage to Galactica is Boomer's jump when stealing Hera. The raptor's jump engines in close proximity to the hull tear a twenty foot hole in Galactica's side. Galactica clear wasn't built to hand spatial distortions as well as she was nuclear blasts.
We see a nuke can be really effective, taking out the resurrection ship with one warhead, and the nuke that went off in the tightly packed fleet above New Caprica was devestating.
However big targets like Galactica and the Hub are routinely targeted with multiple nukes.
As an aside, do you think Pegasus or Valkyrie's hulls would have handled nukes or spatial distortion differently?
