This is the fictional Baka-class missile range instrumentation ship (or tracking ship as they are sometimes called) used for tracking missiles and rockets over vast distances. Due to high cost and relatively niche area of usability, these kind of ships tends to only be in the service of large naval powers.

It's very easy to print and is suited to be printed in the size the model's in (just under 3 cm in length). Final result was really good in my Flasforge Finder.

This is part of a hobby project of mine that included making 200+ vehicles, aircrafts and naval vessels for a fictional armed forces (of the country of Acorsia).
