Spinal Mount (Technology) Synopsis
A Spinal mount — also called a spinal weapon or spinal mount weapon — is a fixed-mount, major starship weapons system which provides for attacks of the greatest possible power. Because a starship's entire structure is built around a spinal mount, hence the name, no starship may have more than one spinal mount.
There is one exception: a so-called "Janus" mount consists of two half-length spinal weapons installed in a single spinal tunnel, one facing fore, one to aft.
Spinal Mount (Technology) Weapon Types
A number of different kinds of weapons may be built into a spinal mount.
