KerbalX

Citadel 1 was missing the new magnetometer… so rather than simply add that part, the very stupid and courageous Kerbals did a TOTAL redesign to make Citadel 2. Result was a 40% parts reduction and slightly reduced size - only 6 Mammoths and 7 LVNs - but still single stage to Minmus. It more than doubles the crew capacity and adds SENTINEL and M700 scanners. Still has a lab, ISRU with fuel cell power and 100G relay dish… all inside 2 large cargo bays. Adds a small drill at the top for asteroids and 6 docking port seniors at the bottom for expansion in orbit (if your PC can handle it with Unity’s poor CPU utilization and the memory leak they still didn’t fix.) Should be able to handle Tylo and Laythe if you manage fuel.
vacuum delta V km/s for Mammoths / LV-Ns:
3.7 / 1.6 as supplied for Kerbin launch to Minmus landing or low Mun orbit
3.2 / 3.3 full
0 / 8 no OX
That’s for simple staging assuming burning LF/ OX first, then LF for LV-Ns. Can also convert ore in orbit for more.
Photos: ignore the RCS tanks at the bottom; I needed them for a contract. My launch angle was too low - lots of flames. 45 deg. at 10 km is about right.
