Section VII: Editors Notes

The USS Proxima (Mk. II Excelsior) was a battleship testbed using the Excelsior hull.  It was intended to counter the threat of war with the Klingons in the late 2280's, but with the destruction of the Klingon moon Praxis, and the subsequent thawing of relations the battleship test ended.  The Proxima was downgraded and became the lead ship for the first Excelsior Upgrade dubbed the Ingram Class.
