When it came to warships, the Red Fleet usually fielded the strongest ones.
Unlike the mechers who liked to turn many warships into part-time mech carriers, the fleeters sincerely believed in the power of pure warships.
From the perspective of the people who controlled all of these impressive vessels, practically every problem could be solved with an excess application of firepower!
The bigger the guns, the better!
The greater the quantity of guns, the better!
It was not without reason why the Common Fleet Alliance back in the Milky Way built over a hundred thousand battleships over the course of many generations. Each additional battleship that measured over 1 kilometer long represented another security guarantee.
Warships tended to last for a long time as long as they were properly maintained. Periodic upgrades to their systems could easily keep them relevant for at least two centuries.
