The Xexon Venu IF6 was a heavy strike fighter produced by Zenlian Drives and Syvatii Unlimited for the GACIAF administration. The Venu IF6 was an extension of the Xexon Teha-class, which was still continually being updated and modified alongside expanding production lines to meet purchase orders. The idea of a larger Xexon model able to operate for a significant period of time away from logistical and supply lines had been discussed among GACIAF military leadership before, but the organization had been unable to find enough need in GACIAF's fleet structure for such a ship until the Shadow Fleet attacks. These massive crises left little infrastructure intact in affected sectors, and would also block FTL lanes with debris from damaged ships, preventing immediate access to potential survivors. Additionally, with manufacturers still attempting to expand operations and build new satellites, stations, and other products for the nations and individuals impacted by the Shadow Fleets, some sections of Ivesceel were left with minimal or no infrastructure for tens or hundreds of years, which allowed criminal organizations to escape GACIAF and TAUFOG law enforcement. GACIAF would thus include a contract for a heavy strike fighter in the CACS Program legislation. Zenlian Drives succeeded in the contract competition with the Xexon Venu IF6, which was able to act in escort and long-range reconnaissance roles, as well as providing heavy strike capability.

The Venu IF6 was a large strike craft, with an optimal crew of three - one pilot and two additional crew who would operate the vessel's weapons, ECM equipment, and handle other tasks to reduce workload for the pilot. The Venu IF6 was intended primarily to escort small groups of capital ships or other ships such as logistical craft, and was armed with a combination of weapon systems to both defend and attack. Defensively, the Venu IF6 had two DLB Ethsha 502 anti-fighter laser turrets, manufactured by one of Syvatii Unlimited weapons divisions. These guns, along with the rest of the Venu IF6's weapons, could use an independent computer or the ship's SI-NC013 Dakli tracking system, which integrated a system-wide LDPPA sensor with AI-assisted path tracking computers to anticipate the movements of hostile ships based on existing data and observed patterns. The turrets could prioritize and attack ships independently or be assigned and guided to targets manually by the crew. Outside of close escort missions, the Venu IF6 could also effectively act as a strike bomber, using a combination of laser cannons, beam cannons, multi-purpose missiles, and anti-ship torpedoes to damage heavier opposition. The Venu IF6 was also durable, using the new Taisenic alloy and Catho-Decacite composites for layered armor plating more capable of distributing and dissipating energy, and incorporating subsurface particle shielding. Perhaps the most important system on the Venu IF6 though was its rating 4.1.27 darkspace drive, an improved model from the Teha-class which had minimal cooldown between FTL transitions and could make 31.52 million times the speed of light. Combined with large fuel tanks, extensive internal storage space, and the necessary accommodations for a crew to operate away from allied forces for almost 3 TAUFOG standard months, the Venu IF6 filled an essential niche in GACIAF's fleet structure. The Venu IF6 was often sent on scout missions into a sector post-Shadow Fleet attack, locating intact or relatively undamaged systems or ships and scanning for safe travel lanes to make relief forces more efficient. The Venu IF6 also was utilized increasingly for convoy escort support and as a supplement to isolated GACIAF units, adding additional firepower without significantly increasingly logistical needs and expanding capability without dedicating an entire capital ship or task force. The Venu-class was so effective during the early Shadow Fleet era of Ivesceel that GACIAF would commission new Venu-class strike craft after the IF6 model ceased production, with the Venu IF10 family of heavy strike craft being the most notable.
