The RAI [Redfield Aerial Industries] and the OAF needed to construct a new super-heavy bomber/aerial battleship to rival the rising ammounts of Arsenal Bird attacks seen in recent weeks. The RAI and OAF's finest engineers and scientists came together in the form of Project XFBB-CCXXXXXVI [Experimental Flying Battleship-256] to construct a series of flying wing ships. The first one was the Masterdon, an enormus super bomber armed to the teeth. Multiple missiles, lots of AA missiles, 16 MOAB bombs, and also an "Actias Bomb", designed to oneshot Actias-class carriers. It also carries an EMP shield, when activated it destroys any missile and disables any vehicle in it's range. 2 more support vessels are under construction.
