The Lost during [[Scouring|the Scouring]],{{Fn|10}} the [[STC]] data for the Lightning was discovered rediscovered during the [[Saint-Saen Crusade]], which liberated twelve worlds in [[Segmentum Obscurus]]. They were found on [[Karnak II]] by an [[Adeptus Mechanicus]] [[Explorator]] team and the designs immediately given to the Mechanicus Lords of [[Cypra Mundi]]. It would take over five hundred years of research and trials, including readings of the [[Emperor's Tarot]] and cross-referencing with the archives of [[Mars]], before the designs were finally approved for production in supplying fleet carriers and cruisers of [[Battlefleet|Battlefleet Obscurus]]. Since then the designs have slowly been disseminated to the Navy worlds of [[Bakka]] and [[Hydraphur]] and Lightnings are now commonly seen alongside the Thunderbolt in both [[Segmentum Tempestus]] and [[Segmentum Pacificus]].{{Fn|1a}} Lightning squadrons are not fixed in size, but most feature more than two dozen aircrafts at the start of hostilities. They will inevitably suffer heavy attrition, only to be reinforced by fresh pilots.{{Fn|10}}
