Those are two completely different types of combatants that operate in different mediums haha
End of Fate's quote
The invention of the aircraft carrier pretty much killed large ships overnight (although it took a couple years for people to understand this fact). So I rest my case: air power dominates the naval battlefield, and even though they're different in nature, it's still a case of a handful of small crafts taking down a much bigger one*. It doesn't make ground and naval forces obsolete, but it pretty much strongly influenced the way they work. Even if it didn't, the fact that weapons technology has outpaced passive defenses by a tremendous amount means that large ships are no longer interesting, because they're not that much harder to sink than small ships. Also, tactical nuclear weapons mean that WWI-style fleets are too easy to get rid of. Put too many expensive large ships in one area and they'll be taken care of with one low-yield nuclear weapon (even low-yield nukes still *vaporize* things too close to the detonation point, and there aren't many defenses against phase transitions :p)
And rather than RIB taking down large ships, I'd have said monitors/patrol boats, or even corvettes/frigates. And you know what? They can. An Exocet or two will sink any Battlecruiser as easily as a corvette.
So yeah, I'd rather not see "bigger is better". Bigger should give more tactical options, but combined arms, consistency of strategy, and adaptation to the situation should be the key elements.
*Fictionnal space battles usually borrow from both naval and air battles. Small spacecrafts are akin to planes, large spacecrafts are more like ships.
