So I stumbed on this game, which seems interesting.
https://store.steampowered.com/app/887570/NEBULOUS_Fleet_Command/it flew under my radar for a while because the store page is absolutely unattractive, but there's a wealth of things that does *really* well
the basic first tho: you get five hulls of varying size, on which you can put internal and external modules (radars, weapons, jammers, etc) - there's a tutorial, and no campaign to speak of, the game is for now various form of tactical battles with fixed fleet point either vs AI or vs players. you can download fleets off steam workshop, and you get a selection of few maps centered around asteroids, to b e played as capture, domination or annihilation.
among the most interesting things is the sensor play. jammer, comms, active and passive radars etc create a limited information battlefield where figuring out what's happening is a challenge in itself. missiles follow similar rules, with similar vulnerabilities to jamming and spoofing, and the option of missiles that will target radar or jammer signatures.
you get various amount of weaponry, with rails sitting at the absolute peak of armor piercing and cannons of various caliber going 450mm down to 20mm for point defence purposes, plus a couple energy based weapons.
weapons have in general more range than sensor, with ships targeting using each other target information - that is, unless their communication are jammed, but jammer (communication and radar) in general act on a small cone of space, so you need to know in which direction to jam to blind or silence the enemy scout.
weapons have specific firing arcs depending on where they're attached, so point defence placement and orientation in combat is paramount to survival. ships will howerver work in bringing attack weapons to bear automatically, so at least there's that.
I've run the tutorial so far and a skirmish, and the commands are quite straightforward, reminiscent of homeworld but there's some more detail that makes them more intuitive
here's some multiplayer gameplay
