Fresh install of the new 1.0.2 worked for me. IE: new, vanilla, unmodded ksp v1.0.4, moded only with what was in the NucEng 1.02 zip file... Worked right off the bat. I then modded this install with all sorts of things and the system appeared stable. Not at my comp or I'd post Gamedata pic. I built a spaceplane using Mark IV parts and an Orion engine..... WHOA!! Got to Jool in no time and was able to fly around in the Jool atmosphere. Pulse magazines of 250kt are best for this endeavour. You'll accelerate more slowly and have more control but still be able to go anywhere in the solar system. Tried to take screen caps but something went wrong and no dice. Haven't done the measurements yet, but it seems Medusa has the same engine performance as Orion. IE, same total mass with the same bomb load gets you to the same ultimate speed. Do you have any plans to make this comparison closer to real world? (Not a criticism.) It would be cool if there were different generations of nuclear pulses that correspond with the different generations of real world nuclear weapons. IE: second gen bombs w/tritium triggers would go into first gen Orions, with limited yield choices (250kt & 500kt only) and very high fallout to match, giving you a high prestige hit per launch. Compared to theoretical fourth gen bombs (that have no fissile material) would be used by third gen Orions, covering all yield ranges (from 10kt to 2500kt) and producing no fallout, and thus no prestige hit. Not sure how much of a pain that would be to implement. But it could be cool.

Roverdude: Love your mods. There's always at least one in any of my installs. This mod is exceptionally awesome. However, the above posts are correct. If you plug just this mod and no other into a brand new, stock ksp install, the menus for changing between bomb types do not show. I tried this several times, not wanting to mod my main game with an alpha release. However, after failing with a stock install, I placed the same download into my main, highly modded, Interstellar Extended game and, after being certain USItools was updated, it worked right away! I conclude that there's something this mod needs that is not included in the zip file. Again: glorious mod! Love it so far! I have suggestions but they'll have to wait. Edit: Sorry I got your name wrong. I first posted this from a phone: auto-correct caught me unawares. Glad to hear the fix was as simple as including Firespitter.
