Engines

Ship Sublight Engines are buildable warship components used for movement in tactical combat. Not to be confused with FTL Drives or Ship Power Cores.

Empires begin with Chemical Engines and may research up to 4 additional engine technologies through the Physics tree. The tech level, production cost, space requirements, and tactical movement speed (in hexes per combat turn) are listed in the table below. Key: P = Production, S = Space

Engine costs and size required are the same regardless of the size or type of the ship. Hence larger ships (Battleships etc) use a smaller proportion of their space and cost on engines, and have more available for weapons, shields, etc.

Engine Miniaturization
As with all ship components, space requirements and production costs are reduced as the player researches levels of applicable tech tree beyond the level where the tech was unlocked. Refer to the Weapon Miniatuarization table - the values are probably the same or similar - or check the exact values in the next section.

Miniaturization Raw Data
Listing Prod cost then Size used, for each TL in the tree, starting at the TL when the component is unlocked.

(This list should be reorganized as a table).
