via the Halo Fanon wiki page:

The CCS-class battlecruiser, also dubbed the Covenant Capital Ship, is the most common warship in the entire Covenant fleet. A development from the older RCS-class armoured cruiser, the sleek CCS-class is built as an expression of the Covenant's power. It is fast, well-armed and shielded, and useful, all in equal measure. Add to this a large complement for a ship of its size, and it is not hard to see why these battlecruisers could be seen from everything from honour guard ships to occupation vessels to forward construction vessels. These ships are looked upon with envious eyes by the rest of the Covenant, and even after the hegemony's fall have continued to cermet themselves as a reliable vessel.

this is a 1:1 scale replication of a CCS class battlecruiser from the Halo video game franchise, it features a partial but fully explorable interior not accurate to the games but inspired by covenant interior design ques seen in later games like Reach and Halo 3. most of the work was done via importing a 3D model into Minecraft and later adding color, light, interior, etc. via numerous methods such as world edit brush commands, or just doing some of the work by hand. it is available for download via schematic file, and is also displayed where I built it, the Military Builders creative server. I highly encourage you to check the server and it's community out not only for the build, but because both the owner and it's people are incredibly passionate about what they do, as well a s being incredibly helpful. this build would not have been possible without their server to serve as my platform.
