Chapter 2: Ship Design
Ship Components Overview
Ships in Mneme Space Combat are built from modular components. Each component serves a specific function and contributes to the ship's overall capabilities.
Hulls
- Hull Configuration
- ; Standard : Atmospheric operations suffer a -2 DM. Can mount Fuel Scoops but DM-2
- ; Streamlined : No penalty in Atmosphere Operations
- Hull Armor
- Titanium Steel TL7+ provides Armor-2 baseline
- Additional armor reduces available Dtons and increases cost

Fuel Tanks
- Standard Calculation
- Varies by operational requirements
- Example Configurations
- 14-28 Dtons for 2-4 weeks operation after jump
- 40-84 Dtons for extended operations (9-20 weeks)
Bridges and Controls
- Bridge Capacity
- 1 station per Dton of bridge
- 10-ton bridge = 10 crew stations
- 20-ton bridge = 20 crew stations
- Standard Stations
- ; Captain : Leadership and coordination
- ; NavComm : Sensors and communications
- ; Engineering : System monitoring
- ; Pilot : Flight control
- ; Gunners : Weapons control (one per fire control system)
- Trading Bridge Space
- Bridge can be sacrificed for ship components at no additional cost
- Available options: Briefing Room, Locker, Luxuries

Supplies and Cargo
- Regular Life Support Supplies
- 54,000 Cr per unit per month equivalent
- Vacc Suit TL8
- 5,000 Cr per unit
- Repair Supplies
- 10,000-20,000 Cr per Dton

- Adjusted Thrust below 1
- Lower to 1/3 for every drive rating needed to reach Thrust-1
