In that case time to build some USNC style ships.
Also to put it bluntly Goa'uld you'll have to suck it up about Battlestar based designs they're about the most efficient carrier/battleship hull you can build
I was gonna shout out to Macross and BSG and Space Battleship Yamato with the Tau'Ri navy looking more like subs/old style warships, with the exception of the Yorktown which will look like the Galactica except with more fighter pods and less railguns and more pump lasers/primitive plasma cannons.
And some unholy monstrosity that can just dump old "decommissioned" cold war era nuclear payloads in modern Naquadah enhanced missiles at everything,.
