Breen dreadnought

That is my fan-made recreation of one of the starships seen is the season 5 of Star Trek: Discovery. The Breen dreadnought.

This begemoth briefly appears during Burnham's and Rayner's time cycling in a timeline where Breen destroyed UFP. Later this ship, commanded by Primarch Ruhn, confronts feds about Moll and L'ak in the latter's custody. Since then this dreadnought is taken into race with USS Discovery over Progenitors' tech. Later it falls over Moll's command, captures the portal to Progenitors' tech, fights with Discovery and ends up being sent away through the use of spore drive.

Essentially this ship is bulky, vertically oriented and unusually symmetrical for the Breen (note their Chel Grett class warship from Star Trek: Deep Space 9 and various other vessels). Armed with shield tunneling device and particle weapons. Its hangar spans throughout its length with entrances at both frontal and aft sections, covered with hexagonal containment field, and is big enought for U.S.S. Discovery to fit in and even turn around. This means that Breen dreadnought is one of the largest starship classes in Star Trek lore (with the size of 6800 meters of only my model). How the series designers came up with this one? One of them claimed to have taken inspiration from various Breen designs, even ones from Star Trek Online describing them as city-sized ships capable of holding armies (I believe that man seen the concept of city-ships of Voth, but didn't know its origins - that's why he extrapolated it on Breen).
