The CFA-44 Nosferatu is a sixth-generation carrier-based stealth aircraft, renowned for its distinct, powerful arsenal and high mobility. The CFA-44 made its debut in Ace Combat 6: Fires of Liberation, as one of the final boss battles in the game, and has been featured in every console game since; it was added as post-launch DLC for Ace Combat: Assault Horizon and Ace Combat 7: Skies Unknown, and available in a post-launch update for Ace Combat Infinity. Since the CFA-44 has appeared in multiple continuities, its development history has adapted to each one. In the Strangereal universe, an Estovakian state-run company, Albastru-Electrice, developed the CFA-44 as an experimental weapons platform. In the Assault Horizon universe, the CFA-44 was portrayed as Russia's next-generation fighter aircraft, which led to the in-universe development of the ASF-X Shinden II. In the Infinity universe, the aircraft was used by the USEA Federation to defend Excalibur and modified to be used as the Butterfly Master's QFA-44 unmanned drone
