Project Leviathan is the hidden project by the Sect and Vesta Corp into producing their own large-scale capital ship or capital ship class, to be built in the new Leviathan shipyard. The Corsair Class Battlecruiser, a class of two ships and one under construction, was the first result of Project Leviathan. They are based on the early prototypes of the final Leviathan design and are much smaller than it will be, though also being much cheaper and faster to build. The Corsair Class is armed with numerous railgun batteries like those on the cruiser, though obviously much more due to the increased size, it also has a pretty powerful CIWS system to make up for the shortcomings of the cruiser in that department. It has a large store of missiles, primarily anti-ship missiles though obviously some interceptors for use against enemy missiles. The Corsair class also has an incredibly large and powerful railgun mounted along the spine of the ship (effectively a MAC from Halo), this was one of the final revisions to the design as it was rushed out of the prototyping phase due to the war with Gredzka The Corsair Class also features several prototype phased-array lasers for use against enemy missiles and fighters, though they are mainly just to test the effectiveness before the eventual construction of the final Project Leviathan design. Basically, the corsair class is between the cruiser and the yer-to-be-built leviathan in terms of, well pretty much everything.
