The '''Xiphon Pattern Interceptor''' was a fighter aircraft used by the [[Legiones Astartes]] during the [[Horus Heresy]].  ==Overview==Capable of both atmospheric and space flight, it carried two pairs of twin-lined [[Lascannon]]s and a [[Xiphon Rotary Missile Launcher]] into battle. This firepower combined with the interceptor's speed and agility made it a deadly opponent.{{Fn|1}} However the design was complex, had limited range, ill-favored by the [[Mechanicum]], and was preferred by the larger [[Wrath Pattern Starfighter|Wrath]]. Thus by the end of the [[Great Crusade]] it had fallen out of frontline service in all Space Marine Legions except the [[Dark Angels]] and [[Ultramarines]], though the demands of the Heresy forced many more Legion's to press them into service once more.{{Fn|2}} The origins of the fighter are long lost, but it shares similarities to the [[STC]] patterns with craft such as the [[Thunderbolt]] and [[Amhut Voyager]]. The design itself was brought into Imperial service in 806.[[M30]] from the [[Rhadamanthys Enclave]]. The fighters performance puts great stress on its pilot, something [[Space Marines]] were naturally able to withstand.{{Fn|2}}
