So this is just what it sounds like, a "large" 1.5 size core module for Andromedan bases. It would have more power, hull, and additional module docking space, and possibly a DisDev or two.

The other thing that it could do would be to dock 4 SatElite Bases to it, allowing the andros to have effectively a Sector Base. It could also be used with 2.SatB's to form a "heavy bases station", or 3 to form a "heavy battle station".
