The Leviathan-class Aerial Platform (S-1XXX FAF designation) is the flagship class of the East Asian Federation Air Forces. The Leviathan is a large aerial assault command craft capable of launching and recovering massive amounts of smaller aircraft. Powered by Fusion and Anti-Gravity, the aircraft is capable of near-infinite flight time, with landings only required to rearm and restock for crew maintenance. This allows it to act as a flying "aircraft carrier" to support Federation armed forces in global conflicts. There is currently two Leviathan-class in service, the FAF Leviathan (S-1000) and the FAF Danketsu (S-1001). The possible third ship, the FAF Pyeonghwa (S-100X), is under preliminary contracting.


Construction of the FAF Leviathan began in September 2005. The construction of the Leviathan is seen as a greatly contributing factor to the success of the Asian Free Trade Agreement because of the massive amount of raw materials required and the resulting trade between the East Asian Federation and the Grand Yarphese Republic. Construction was conducted in secret in the northern mountains of the Korean Region of the Federation and was completed on January 1, 2010. On February 1, 2010, the Leviathan was unveiled for the public. Construction on a second iteration, which began in January 2006, was completed on April 30, 2010.


The S-1000 series' low-observable characteristics give it the ability to penetrate an enemy's most sophisticated anti-air defense lines to deploy specially trained elite air wings behind the front lines. The aircraft's stealthy appearance comes from a combination of reduced infrared, visual, and radar signatures, making it difficult for opposition defenses to detect, track and engage the aircraft. The S-1000's composite materials, special coatings and flying wing design contribute to its stealth characteristics. The engines are buried within the wing to conceal the induction fans and hide their exhaust.
