The X-02 Wyvern,[a] also known as the X-02A, is a fifth-generation fighter aircraft developed by the Erusean Air and Space Administration. Its striking design is most notable for its variable geometry wings, which fold in at high speeds. The X-02 Wyvern incorporates an uncommon design with variable geometry technology and a forward-swept wing configuration. As the aircraft gains speed, the forward-swept wings and vertical stabilizers fold inward and downward respectively to reduce air drag, and retract to their neutral position once it slows down. This unconventional design grants it an extreme degree of mobility and the folded wings add a degree of stealth.[2] However, this comes at a cost to the aircraft's armor (which is scaled back to provide such mobility) as well as its fuel capacity.[3] The aircraft is carrier-capable, though is equally capable of taking off from standard airfields.The X-02 incorporates a weapons bay between the intakes on the underside of the aircraft. This weapons bay is capable of carrying all kinds of special weapons, including air-to-air missiles, air-to-surface missiles, and various bomblet dispensers. The aircraft's standard missiles are launched from downwards retractable holders located on the undersides of each intake. The X-02 is powered by two tri-dimensional thrust vectoring ERG-1000 engines.
