In the Anno Domini time line, the Earth's three space elevators are covered by ablative armor plates to protect their structures from damage. Selected spacecraft are also able to deploy ablative gel for high-velocity atmospheric reentries. In the Cosmic Era time line, the ablative armor concept is applied in similar capacity to the anti-beam coating and laminated armor technologies utilised by mobile suits as a form of protection against beam and laser weaponry. In the Universal Century time line of the Gundam series, ablative coatings are used to minimize the effect of beam weapons, called beam resistive coating and a later improved version, Anti-beam coating. In the online game DarkSpace, ablative armor is utilized to counter projectile-based damage while making the ship more vulnerable to lasers and energy-based weapons. Regenerative ablative armor is powered armor that can restore the ablated material. The boil-off rate creates a particle cloud that is dense enough to disperse the incoming beam's energy. The Star Trek: Deep Space Nine Technical Manual explains that ablative armor works in two stages: When the shields are hit by an energy or particle weapon, thermal energy from the ship is dissipated across the hull. Having been introduced in the year 2371 of Star Trek's fictional future timeline, it features on starships including the USS Defiant, USS Prometheus, and an upgraded USS Voyager. Uses in fiction Star Trek Īblative hull armor appears frequently in the Star Trek universe.
Īblative armor is distinct from the concept of reactive armor which is actually in common use in modern armored vehicles. In recent years, the concept has had widespread usage in robot combat as a method of reducing impact energy transfer to vital components. The idea is also commonly encountered in science fiction. A large amount of developmental usage was on the early 1960s rocket powered X-15 manned aircraft traveling at hypersonic speeds in excess of Mach 6.5 (roughly 5,000 mph). 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 probe.
