Ablative armor was a type of protective hull plating used primarily on starships, and later on deep space stations (circa 2385), which possessed a capability for rapidly dissipating the energy impacts from directed energy weapon fire. Ablative armor which was developed by Starfleet in the late 24th century, was designed to provide an additional layer of defense to starships.

HistoryEdit

Starfleet began use of ablative armor technology by 2371. It was first used on the USS Defiant, the prototype of her class, during the vessel's commissioning as a station defense complement of Deep Space 9 after first contact with the Dominion and the Jem'Hadar. Later, after satisfactory field tests with the Defiant, the technology was used on Prometheus-class tactical assault cruisers.

Ablative Armor PlatingEdit

A key difference between simple ablative armor as used on the Defiant-class and Prometheus-class and the ablative armor plating used by the Intrepid-class USS Voyager in 2377 was that the old armor was a simple alloy layer that eroded into a diffractive cloud as it was retarded by the phaser beam and then permanently diminished, while the generated ablative armor plating was a series of hull-mounted replicators and transporters that continually rebuilt a completely new hull of armor around the entire hull of the ship as the armor hull is damaged.

The ablative generator was designed to protect starships by generating a nearly impenetrable hull armor, which was deployed from the externally mounted generators, that when deployed spread across the ship's entire hull, following its contours. Though phasers could not be fired while the ablative armor plating was deployed, apertures allow torpedo launchers for the use of torpedoes. Though designed specifically to defend against the Borg, it was shown to be highly effective against other types of weapons fire. With armor deployed, Admiral Janeway's shuttlecraft was able to withstand disruptor fire from a 25th century version of a Klingon Negh'Var-type heavy cruiser without any loss in armor integrity.

Vanguard CommandEdit

By 2385, ablative hull armors had been incorporated on all newly built starships and starship classes, particularly the Invincible, Suzerain and Yamato-class of capital ships. However, a ship could only use multiphasic shielding or the ablative armor plating interchangeably but not at the same time, owing to the large amount of energy that would be spent in activating the two defensive systems at the same time.

A double coating of ablative hull armor had also been integrated on the structures of two refurbished and refitted Nor-class Cardassian space stations that had been acquired by Starfleet from the Cardassian Union and were recommissioned and then towed to the Gamma Quadrant and Delta Quadrant, respectively. These are Station Deep Space Gamma-01 and Station Deep Space Delta-01.
