Heliopause Forts

Heliopause Forts are a group of 50 known Space Forts that form a cocoon of protection around the Sol System.

The cocoon is spherical and has a radius approximately one hundred times the radius of Terra's orbit around Sol.

Classified Blue-Blue-Red
There are only 50 Heliopause Forts, but there are hundreds of automated weapons platforms that can be controlled by those forts. The rumors of additional forts are carefully cultivated, made more believable by the fact that about a third of the automatic or remote controlled weapons platforms can be converted into fully functional forts within a short period of time.
