Ablative armor
Encyclopedia
Ablative armor is armor designed to negate damage or destruction to itself from the process of ablation
Ablation
Ablation is removal of material from the surface of an object by vaporization, chipping, or other erosive processes. This occurs in spaceflight during ascent and atmospheric reentry, glaciology, medicine, and passive fire protection.-Spaceflight:...

. In contemporary spacecraft, ablative plating is most frequently seen as an ablative heat shield for a vehicle that must enter atmosphere from orbit, such as on nuclear warheads, or space vehicles like the Mars Pathfinder
Mars Pathfinder
Mars Pathfinder was an American spacecraft that landed a base station with roving probe on Mars in 1997. It consisted of a lander, renamed the Carl Sagan Memorial Station, and a lightweight wheeled robotic rover named Sojourner.Launched on December 4, 1996 by NASA aboard a Delta II booster a...

Ablative armor is distinct from the concept of reactive armor, which uses a sandwich layer of explosives to disrupt the thrust of armor piercing ammunition, and is actually in common use in modern armored vehicles.

Space colonies and ships of the future will almost certainly require a type of ablative armor to withstand space radiation and heat. When traveling at higher speeds the momentum of the particles the ships will encounter will be large, and require more protection.

. The Star Trek: Deep Space Nine Technical Manual explains that it works in two stages: when the shields are hit by an energy or particle weapon, phaser or thermal energy from the ship is dissipated across the hull. This creates a boil-off rate that carries away most of the incoming beam's energy. Most of the time the boil-off creates a particle cloud that is dense enough to disperse the incoming beam.

The mass of the ablative armor plays a large role in how much damage it is able to absorb. Even a 10% difference in mass can mean 100% difference in the amount of damage it is able to absorb.

Regenerative ablative armor is a similar type of armor that adds power to the armor to be able to withstand more hits, it is similar to shields in the fact that it can be recharged.

 EVE-Online, ablative armor plating is utilized as a secondary defensive layer that protects the relatively fragile internal systems. Depending on the ship's loadout configuration, a ship can continuously repair incoming damage on the armor, fit additional armor plates to sustain large amounts of damage in the short term, or remotely repair friendly ships' armor using specialized modules. The rate at which the armor gets depleted depends on the types of damage incurred to the armor and the armor's resistance value against each particular type of damage.

Armor plating is usually considered strong against electromagnetic(EM) and thermal(TH) damage, and weak against kinetic energy penetrators

 there are several variants of armor for all races referred to as ablative.

Warhammer 40000

In the tabletop RPG Inquisitor, ablative armour may be layered on top of other armour. If the ablative armour is struck, it is destroyed (after the damage caused by the attack is reduced accordingly). Ablative armour may have additional properties such as added resistance to heat- or laser-based weaponry; if special ablative armour is destroyed, it loses those additional properties. Unlike other types of armour in-game, ablative armour is quite cheap to purchase (since it is so easily destroyed).
