This paper model is a Voss Lightning Strike Fighter II, an air superiority fighter aircraft and ground attack craft used by the Imperial Navy for the purpose of quickly assaulting and defeating the enemy in aerial dogfights in order to establish air superiority over the battlefield, based on the game Warhammer 40k, the papercraft was created by Patoroch. The scale of the papercraft is in 1:60.
The Lightning is smaller and much more maneuverable than the heavier Imperial Thunderbolt Fighter (also a Repaint Version paper model at the site), and can be quickly scrambled during an enemy attack. The craft is capable of short take-off and landing (STOL) and vertical take-off and landing (VTOL), and when stationed on the ground, either at a permanent airbase or a forward operating base during a mission, the Lightning can use hydraulic ramps to get into the sky and into combat almost instantaneously. The Lightning is also capable of limited spaceflight in a vacuum and atmospheric reentry so that it can be launched from Imperial starships in orbit and unleashed anywhere air support is needed by Imperial forces during a planetary assault.
The Standard Template Construct (STC) design for the Lightning were found by Adeptus Mechanicus Explorator teams on the world of Karnak II after the Saint-Saen Crusade, which liberated twelve worlds in the Segmentum Obscurus. The database's design was transferred to the Forge World of Cypra Mundi, where the Lords of the Mechanicus consulted with the Emperor's Tarot and followed the advice of their oldest and wisest Tech-priests. The design was cross-referenced with the Mechanicus' vast archive on Mars before its rediscovery was determined to meet with the favour of the Machine God, and the manufacture of the Lightning began in earnest.
After nearly half a millennium of trial and error, the Lightning saw its first service with the Imperial Navy's Battlefleet Obscurus, and after all the engineering difficulties with reproducing the Lightning's advanced swept wing design were worked out the aircraft went into full production and was soon being supplied to all of the Imperial Navy's Carriers and Cruisers. The Lightning's STC data was eventually shared with the major Imperial naval centers of Bakka and Hydraphur, and now the Lightning is in service with the battlefleets of the Segmentum Tempestus and Segmentum Pacificus as well as the Segmentum Obscurus. Lightning production has recently begun within the Segmentum Solar, resulting in a new pattern of the aircraft known as the Voss Pattern Lightning Strike Fighter, which originated on the Forge World of Voss.
The basic armament of the Lightning is that of an air superiority fighter craft. It is armed with a single ventral-mounted, long-barrelled Autocannon, two wing-mounted Lascannons, and four wing-mounted Hellstrike Missiles. This weapons loadout, combined with the Lightning's superior speed and maneuverability, make it a fearsome fighter perfectly suited for aerial dogfights with other aircraft. The Lightning can replace its Hellstrike Missiles with Hellfury Missiles or the air-to-air Skystrike Missiles and it can also be adapted to carry bombs. The Lightning can be outfitted with an ejector seat, flare or chaff launchers, a more heavily armoured cockpit, infrared targeting systems, and illumination flares.
The Strike variant of the Lightning, known as the Lightning Strike Fighter, is a variant of the standard Lightning Air Superiority Fighter that has been modified to fulfill a ground-attack role. The Lightning Strike variant is the same as the standard Lightning pattern, save with a different weapons load-out which removes the ventral-mounted long-barrelled Autocannon to save weight and adds additional Hellstrike Missiles. This variant of the fighter is primarily used to attack enemy armour on the ground and as a heavy air support unit for ground forces such as Imperial Guard or Space Marine infantry.
