EMU Launcher – Required Equipment

The EMU launcher is designed to sit on top of the core ISRU capabilities of any lunar industrial outpost. Drilling, smelting, compression, and basic regolith processing all belong to the standard ISRU toolkit. Only a small fraction of hardware is unique to the EMU itself. This separation keeps the launcher lightweight, scalable, and easy to replicate.

Standard ISRU Equipment (Baseline Lunar Infrastructure)

These systems must exist for any regolith-processing operation, regardless of whether an EMU launcher is deployed. The EMU simply reuses this industrial backbone without needing specialised new versions.

Drilling & Subsurface Operations

Rotary and percussive drills for regolith and ice
Thermal drill heads for deep bore formation
Augers and bore-shaping tools
Bore casing and lining equipment
Depth, temperature, and bore-stability sensors

Material Extraction & Processing

Regolith crusher / grinder
Magnetic separator for iron-bearing fines
Regolith compactor or sintering press
Bulk storage hoppers and material feeders

Smelting & Metalworking

Fresnel-lens or heliostat solar furnace
Refractory-lined iron melting crucibles
Casting molds for shells and structural parts
Cooling racks and mold-release tooling
Precision mass scale
Component storage racks

Gas Production, Storage & Compression

CO₂ extraction or tank storage
Water electrolysis system (optional)
High-pressure storage vessels (pressure tanks)
Solar-thermal or electric gas compressors
Gas filters, dryers, and particulate traps
Regulators, relief valves, and instrumentation

Power & Thermal Infrastructure

Photovoltaic arrays for instrumentation
Solar concentrators for high-temperature processes
Thermal storage tanks
UPS / battery systems
Power distribution cabinets
Sun-tracking systems

General Operations, Monitoring & Safety

ISRU operations and monitoring console
Inventory tracking for materials, gas, and shells
Temperature, pressure, and structural telemetry
Dust mitigation tools and cleaning kits
High-temperature handling tools
Non-water fire suppression systems
Shock-isolated storage for pressurised tanks

All heavy machinery—drills, furnaces, compressors, material processors—belongs to this category. These systems form the backbone of ISRU and are not unique to the EMU launcher.

EMU-Specific Equipment (Unique Launcher Components)

This is the true “EMU footprint.” These lightweight, non-complex components convert a standard ISRU borehole and metal shop into a functioning mass-launch system. Their simplicity is the core of the EMU’s scalability.

Bore & Barrel Conversion Components

Shaped 30–60 m barrel geometry inside an existing ISRU borehole
Ceramic / basalt-glass / sintered-regolith barrel liner segments
50 cm sacrificial throat liner at the surface
Launcher mouth cover (dust & sublimation protection)
Fixed sun-shade hood or reflective baffle
Dedicated throat temperature & sublimation sensors

Projectile Integration

Standardised iron shell molds for projectile casting
Obturator ring press (iron or ceramic rings)
Bore-diameter gauge tool
Shell smoothing / polishing tool
Shell staging racks near breech

Breech & Loading Mechanics

Mechanical loading arm or slide-rail loader
Single-shot or multi-shot breech cavity
Mechanical interlocks (prevent pressurisation while open)
Manual safety lockout system
“Shot Ready / Shot Fired” mechanical indicators
Blast shield for loader zone

Impulse Delivery System

Fast-acting pulse valve for pressure release
Flow restrictors tuned to EMU impulse profile
Shock dampers matched to projectile mass
Gas injection pressure & temperature sensors

Maintenance Tooling

Throat-liner replacement kit
Bore smoothing / reaming tool
Bore-wall diagnostic tool (optional)

Optional Cluster Upgrades

Multi-breech carousel
Robotic loader for high-cadence EMU clusters
Mass-capture beacon on outbound shells
Shell recycling depot in lunar orbit

Extracting EMU-specific components from the ISRU toolkit reveals just how small the launcher’s unique footprint really is: a bore liner, a breech, a loader, a pulse valve, and a few maintenance tools. This minimal overhead is what enables the EMU to scale rapidly from one tube to dozens or hundreds.
