LGM-30G Minuteman III
The complete ICBM system for KSP 1.12, at true scale.

The missile flies with its own guidance computer, launches from its own silo and ends with a physically modelled nuclear detonation. No MechJeb or kOS needed.
Features
- True-scale missile: 18.22 m, 35.4 t. Every stage, interstage, shroud and RV is a separate part with a custom 3D model.
- Two loadouts: MIRV with three Mk12A reentry vehicles, or a single Mk12A on the centre station. Ready-to-fly crafts are included for both.
- Three variants in one download: stock Kerbin, Realism Overhaul / RP-1 on Real Solar System, and RO on Sol (RSS Reborn).
- NS-50 guidance computer: flies the whole mission from LAUNCH to impact. It handles the ascent profile, closed-loop steering, staging, stage 3 thrust termination and MIRV targeting.
- Custom interface:
- a mission timeline in military test-report style
- an extended scientific log
- a zoomable target map
- automatic MIRV / single-RV detection
- Vandenberg LF-10 silo:
- sliding closure door, 5 s countdown and a hot launch from the tube
- adapts to RSS or Sol by itself
- MM3Nuke W78 warhead (20 t to 1.2 Mt):
- visuals: flash, fireball, Wilson cloud, mushroom cloud
- destruction: blast wave and thermal radiation destroy parts, vessels and buildings
- scaled after Glasstone & Dolan
- Realistic exhaust: Waterfall plumes per stage, and a custom PBV flame with shock diamonds.
- RO integration: RealFuels propellants, RP-1 tech tree entries, and RealAntennas support.
- Included: 4 ready-to-fly crafts, full source code and the model generators.
The missile
Stage 1 (M55A1), stage 2 (SR19), stage 3 (SR73), the post-boost vehicle and the shroud each separate as on the real missile. A continuous cable raceway runs from stage 1 to stage 3 and leaves cleanly with each stage.

MIRV loadout
The post-boost vehicle carries three Mk12A RVs. The guidance computer gives each one its own target, then turns, burns, aligns and releases it with spin-up.


Single-RV loadout
One Mk12A on the centre station of the bus, straight up the missile's axis. The PBV shows the matching mount, and the interface offers a single target.



Requirements
- Required: KSP 1.12.x. The missile, guidance computer and warhead work in stock KSP with no other mods.
- Optional – only for the Vandenberg LF-10 silo and the real-scale variant:
- Realism Overhaul, RealFuels and ModuleManager
- Kopernicus with Real Solar System or Sol (Sol also needs ParallaxContinued)
- Kerbal Konstructs and KSCSwitcher
- Recommended with RO: Waterfall, ROWaterfall and SmokeScreen for the stage plumes.
