Void Armor

Void Armor, also known as Asteroid Shielding or Deflective Armor, is a construction technique used to protect against micro-asteroids and other small hypervelocity impacts. Void Armor is typically made of calfen to reduce its weight and improve its maintainability. Modern void armor is composed of a multitude of honeycomb modules whose interior is filled with small calfen plates, facilitating production and repairs. Due to its fundamental principle, void armor is exceptionally bulky, but much lighter than the underlying composite armor often found on spacecrafts and stations.

Almost every single space asset in Elysium is equipped with void armor, as debris and micro-asteroids are a permanent and omnipresent threat. As such, void armor can be procured and repaired nearly anywhere with ease due to its low construction costs and the use of abundant materials. Some spacecrafts can even repair their own armor through the use of fabricators and repair drones, most notably military spacecrafts and space stations. On the contrary, some spacecrafts are not equipped with void armor due to their poor resistance to atmospheric re-entry. As a result, all transatmospheric aircrafts are instead equipped with heat shielding rather than void shielding, and would typically require the support of a larger vessel for interplanetary or interstellar travel.
