Plans for an immense battlestation capable of holding its own against several strike fleets are now being drawn up. If realized, these citadels will become monuments to greatness as much as system hubs.
Standardized Battleship Patterns	10000	4	–5% Battleship build cost +25% Battleship build speed	Battleships	Base: 40 Modifiers 1.25x if scientist expertise is voidcraft.	Establishing new standards for how we design and construct massive battleships greatly improves the speed at which they can be assembled.
Improved Battleship Hulls	12000	4	+800 Battleship hull points	Battleships	Base: 35 Modifiers 1.25x if scientist expertise is voidcraft. 1.25x if adopted Supremacy tradition tree.	Advances in building techniques will allow for the construction of sturdier and more durable battleships.
Advanced Battleship Hulls	15000	5	+800 Battleship hull points	Improved Battleship Hulls	Base: 30 Modifiers 1.25x if adopted Supremacy tradition tree. 1.25x if scientist expertise is voidcraft. 0.25x if scientist has none of: Expertise is voidcraft. Trait is curator. Trait is spark of genius.	The latest generation of battleship hulls have optimized structural integrity fields and improved bulkheads.
Fortified Core Layers	20000	5	+10% Defense platform health	Improved Structural Integrity	Base: 12.5 Modifiers 0.01x if researching another repeatable tech.	Additional layers of armor plating within the structure itself improves the resilience of Military Stations.
