Ion Hardened Armour

Ion Hardened Armour is a metal alloy designed to contain and resist electrical forces, such as ionization induced by ion cannons and electromagnetic pulse weapons. It would not only be expensive to cover the entire hull of a capital starship with ion hardened armour, it would also be inefficient, since standard armour is more effective against common space weapons such as turbolasers. Additionally, it is not possible to completely negate ionization damage; IHA simply raises a ship's resistance to it. Therefore, IHA is typically employed to protect especially electrically sensitive areas, such as control systems, targeting systems, sensors, and navigation. The usefulness of IHA is that it makes it much more difficult to disable or mission-kill a warship through ionic weaponry. IHA is applied with three different grades of effectiveness, which reflects on the thickness of the armour, its quality grade, and the sensitive area coverage percentage.

Some experimental designs with IHA uses an adjustable level of IHA with sliding armour plates. The intention of this type of design is to allow the best combination of ionization resistance and sensor sensitivity. Simply put, the more sensitive sensors a ship has, the more vulnerable they are to ionization. One way to protect sensors is to change their mode; passive search mode is the least vulnerable and gives the longest range. However it is also the search mode with the least resolution. Variable IHA allows the sensor systems maximum protection while in combat, or the free range of unprotected systems while searching long distance or in focus mode. In short, it allows the ship's commander to select what compromise between protection and sensitivity best fits a given situation. Non-variable IHA offers the same built-in compromise all the time, and the only option is different sensor modes. Variable IHA is not yet available on any standard warship in the NIF, but it is likely to be a future feature.
