im late but ill react anyway dont know if you are looking for novel or a manga but ill put some here
novel: Sigma 16 / shipcore
Manga: The Galactic Navy Officer Becomes an Adventurer
honestly the manga is not too much space / spaceship only at the start so far but still this is what came to mind
sigma 16 is sort of a kingdom builder i guess heard its similar to games like subnautica/factorio
shipcore is a little diffrent and focusus more on story/space battles but has kingdom building i guess more of a galactic empire building tbh but yea
oh also have this manga
Unparalleled Path - Reincarnated as the AI for a Space Battleship
this honestly did not recieve the love it should have :( besides the last one all are ongoing let me know if i was helpful and if you have similar storys pleas share them

"The Galactic Navy Officer Becomes an Adventurer" has sci fi elements, war, and kingdom building. No spaceships except in the very beginning.

"Mezametara Saikyou Soubi to Uchuusenmochi Datta node, Ikkodate Mezashite Youhei toshite Jiyuu ni Ikitai ; Reborn as a Space Mercenary: I Woke Up Piloting the Strongest Starship!" has spaceships and war but no kingdom buiding yet.

"I'm The Evil Lord Of An Intergalactic Empire!" technically has all three, but in small amounts as it's mainly a comedy. Ignore the title claiming he's evil, he's just edgy as hell.
