Player built sensor guided torpedoes could be effective. Just need to increase enemy detection range
Building sensor guided torpedoes would be a cool way of spicing up warfare in no script, vanilla pvp or pve games. Currently it is possible to build sensor guided torps, but the 50m range on the sensor makes it completely unpractical. Just need to increase the enemy detection range on the current sensor to around 800m-1000m, or to make a new long range sensor block specifically for detecting ships and not voxels.
Not just torpedoes, but for example early warning systems and other automatic base defense systems would become possible.
Similar things are currently only possible with scripts and mods.
