Shields

Limited to one per planet. Through the use of huge field generator coils, the Shield Generator taps the planet's core to harness the power of its magnetic field. This creates a paraboloidal energy barrier 1 hex in radius that is invulnerable to space bombardment of any kind. Due to its shape, the shield does not protect against ground attacks nor preclude ships from landing under it.

Shields cannot be constructed until Discontinuity Field Generator has been researched. 

The Shield can also be used as a fabrication plant for the construction of House Flagships. The planet's core is a perfect energy source for this endeavor and the protection the Shield offers can keep the construction both safe and secure.

See Volume 5, Chapter 46 for more information on the the construction of House Flagships.
