no military ships in shipyard

I'm not sure what's going on or if its something new I'm missing but I have no military ships showing up in my shipyard. my last playthrough was a few months ago and I started off with the ability to build fighters. this time nothing is showing up. I researched frigates and cruisers but they never showed. I don't design my own ships. I tried that and didn't like it so I stick with the generic builds that the game provides. I reloaded my old playthrough and the ships where there, went back to my new playthrough and they are still missing. I tried starting as a new civ but still no ships to build. without military ships I really cant play this game so I don't know if its a bug or by design and its a setting I'm missing with the new patch but I would appreciate it if someone could help me out. thanks

also I did go into ship design just to see but I had no weapon or defenses that I could build my ships with and the game told me military ships needed a weapon mod before saving. well there were none to place on it so again I don't know if its a bug or something I'm missing.
