Kerr, no worries. on consideration I think I like having it all here and the feedback we've been getting indicates that quite a lot of people are enjoying this thread. Although I do wish some of them would post more. I always am humbled by the amount of brain power on display here. I hate not being the smartest guy in the room but I have had to learn to live with it. Anyhow, back to the grind stone. Yeah, solid fuel, preferably a mono-propellant would ideal for this bunker buster. Something like MOP would be characteristically Adamite. No subtlety. No finesse. Just brute force and fucking enormous rocket motor. I'd be okay with something as heavy as ten tons all up weight. If they need to hit something really deep they're completely blase about nuclear bunker busters.

With the explosive variant I ended up with something very similiar to GBU-57. Something similiar to an god of rod won't work in atmosphere. The acceleration is just too low. Sorry, but I don't want to work out Aerodynamics to get optimized shapes for maximum terminal velocity. If you want I can present you some stats for rods from god that you launch with spaceship or long range missiles. Something different I could help out? I have an 8km/s 8kg missile lying around. I can give it an solid fuel if LiH-Fl is a problem. Do you have a chat client. We might want to stop cluttering up the boards with minutiae? But I like reading all of this! |

I am glad to read it. I am currently finishing up the details of the Round Table class LS(O) I posted earlier. My slow fire rail guns are too big to fit.

What's the role you see for the second missile? Precision anti-armour fires from orbit? |

3kg at <2km/s is pretty sucky for anti-armour work

Guys. It's becoming apparent that any attempt at signature reduction is a waste of effort. I'm sure you've noticed that all of the SCN ships have hulls coated in VANTA. I'm not sure this is worth the bother so I'm looking at different hull finishes. I'm thinking natural graphene grey or gloss white. However, when I use the white refractive index it comes out grey. Any thoughts?

It is just an low cost guided missile. |

ironclad6You might want to use 45nm FELs instead of 9nm ones. With an 10m mirror you get an spot size of 0.66m and 3.3m respectively. If your FEL produces 100x 10ms 200MJ pulses you will get drill depths in graphene/CNT of 2cm for an 45nm FEL and 48cm for an 9nm FEL. With an 9nm you will either disable or annihilate any Adamite ship in one shot.

Do you have a chat client. We might want to stop cluttering up the boards with minutiae? I usually use gmail to discuss such things. We could also chat via "Messages" festure of this forum Or use the CoaDE discord. |

ironclad6I've found a way to use my initial 500kg Bunker buster in a missile. The lenght of 3m made it hard to incorperate it to an atmospheric missile. But I decided that I put my fuel tanks around the bunker buster to minimize lenght and to improve Aero stability. The bunker buster has an 50kg Octa charge spreading 450kg Osmium/Tungsten as 5g fragments moving at 1250m/s. Alternatively an Thermobaric warhead can be installed. Too increase damage to underground personal. The Bunker buster can penetrate 11m rock, 16.5m dirt and up to 12m concrete, depending of impact velocity. An 8km/s MH delivery system would weight only 1100kg. KEBB-Kinetic Energy Bunker Buster. 10m long, 0.2m diameter. 6.3t ton mass. I've given this rod an drag coefficent that of an standart rifle bullet. It's terminal velocity is 3km/s. It is made out of an inert osmium alloy and has an depletd uranium core inside for extra penetration power and incendiary fun. The KEBB has to be droped from 450km height. This requires either spaceship launch or an 20t MH missile. KE is 6t of TNT. Penetration is regardless of material +50m.
