Planetary Weapons

[Puke]

you can sneak napalm or plague bombs on an escort, and run them up past defenses. thats about the only use that I have found for them.

killing a planet in very few shots, when you know you are not strong enough to fight a conventional space battle against the defending fleet.

as for radiation bombs, the theory is that they will soften up a planet for attacking troops. I have not found these to be usefull at all, perhaps if planetary militia strength was vastly increased...
