I actually think something as simple as a few wings of Herc2s armed with Maxims could completely replace bombers against the majority of Federation targets. They're not as vulnerable, their payloads can't be shot down and they don't even need to get in close.
UEF ships may start rolling with Maxim-resistant armor, though.

I must say, that sounds inherently stupid. The Maxim is shooting a pretty large caliber projectile made of U-238 (depleted uranium) at (for FS speeds) very high velocities. The notion that you could just pass off the tremendous kinetic energy and momentum from those weapons is just silly - even something like ERA (Explosive Reactive Armor) is pushing it as, hey, it blows up to prevent an incoming round from making contact! Destroyable armor plates are one thing, but armor "resistant" to physics and/or common sense is entirely different. And, as a disclaimer, I will note FS makes legendary stabs against physics, but simultaneously it has a sort of believable gameplay to it (thus not conflicting with common sense).
*EDIT: Thanks, Klaus, I can't belive I stuck the fissionable uranium isotope in there! U-235 changed to 238.
