Background:

The structural integrity field (SIF) is another of the basic requirements for any modern spacecraft. This field is projected through the basic structure of a vessel, essentially turning the material into a cross between matter and forcefield. This increases the strength and rigidity by orders of magnitude, allowing the materials to withstand the stresses associated with both normal and combat operations.

The Structural Integrity Field of UFED vessels can also serve as a secondary backup to the ships main shielding system if required; when run at above normal capacity the system is capable of protecting a vessel from even multiple direct hits by heavy weapons. This makes the SIF a key component in the protection of a Starship.
