ICBM offers many different types of missile and explosives. There are hypersonic explosives which suck up blocks into a vortex and then shower them across the landscape, endothermic explosives which cover the surrounding in a layer of ice and red matter explosives which create a never-ending explosion which can devour your world.
This is the most well thought out and the best implemented explosives mods for Minecraft out there, and is definitely worth checking out.
