- Ablative Armour - Text by M. Alan Kazlev
Any armour that protects against beam or HE weapons by ablating, or vapourizing, as it is hit, dissipating the destructive effect of the weapon. Because ablative armour is soon eroded it is not much use in a sustained firefight. Includes soft, hard, laminated, reactive, and smart ablatives.
- Ablative shielding - Text by M. Alan Kazlev
Most space and interstellar probes and vessels use some form of ablative heat shields; their outer surface is coated with heat-dissipating shielding that burns away upon impact with relativistic particles (for interstellar vessels) or during atmospheric entry at high speed. Ablative shielding is also used as a defense against beam and particle weapons.
