NCIA-93 type
The NCIA-93 type was a class of Federation starship utilized by Section 31 during the 2250s.

Technical data 
Ships of this type had the ability to alter their appearance by disguising themselves as another object such as an asteroid, and could use a tractor rig to boost the strength of their tractor beams. 

When necessary, these ships could mask their warp signatures to prevent detection (), and could also emit graviton beams from their deflector arrays.  ()

Physical arrangement 

Ships of this type were smaller than contemporary  vessels and were constructed with a darker hull color than other Federation vessels of the era.  The primary hull was triangular, similar to the 22nd century Warp Delta design used by United Earth.

These vessels were able to retract their nacelle pylons when not at warp.

Interior design 
Internally, the NCIA-93 type featured a two-storey bridge and a drab, overall minimalist design.  Corridors and rooms aboard these ships were considerably darker. ()

Ship's commissioned 
At least three ships of this class were in service as of late 2257. ()

Background information 
The ship's camouflage system is similar to a feature of a Romulan drone ship fielded shortly before the Earth-Romulan War. That ship used multispectral emitters to achieve the effect.

The computer systems aboard NCIA-93 appear to be different from those on  and , and are visually similar to LCARS.

Eaglemoss/Hero Collector's Star Trek: Discovery The Official Starships Collection partwork identifies this type of vessel as a Section 31 "Stealth Ship".
