I don't see why carriers would make dreadnoughts obsolete - they fill different roles. The chief effect of carriers would seem to be to effectively give FTL capabilities to fighters, which would make offensive operations easier and perhaps reduce frigate's screening role in fleet engagements.
All of the galaxy's warships seem pretty much useless against the reapers, though.
Space carriers appear to make space dreadnoughts obsolete for all the same reasons that real carriers make real battleships obsolete.
That doesn't make much sense, The only reason carriers on earth made Battle Ships opsolete is because carries could launch attacks far out of the range on a battle ships guns. Where in space the Carriers would be at the dissadvantage. The Dreadnuaghts have practally unlimited range, firing rounds that move just under the speed of light. They would easily snipe a carried from half way across a solar system and move away before the carrier could even scramble it's fighters and have them get into range of attacking or even move out of the way.
Your estimation of dreadnought weapons is incorrect. According to the codex....
"An 800-meter mass accelerator is capable of accelerating one twenty-kilogram slug to a velocity of 4025 km/s (1.3% the speed of light) every two seconds."
1.3% of light speed isn't in any way "just under the speed of light". At 1.3% of light speed, a carrier would have plenty of time to evade a projectile fired from long ranges. Also, defending escort vessels would have plenty of time to engage incoming projectiles with active defenses.
Reading this sentence. It looks like 4025 km/s is not the max velocity of a mass accelerator, just the acceleration for the slug is 2012.5 km/s^2. Since the sentence says "every two seconds" rather then "in two seconds".
I don't think that's what it's saying. I ran the math. A 20 kilogram slug traveling at 4025 km/s has the kinetic energy of a 38.7 kiloton nuclear weapon. In the game, the gunnery guy speaking to the recruits on the citadel makes the point to the new recruits that the slug
impacts with this much kinetic energy, and that a dreadnought fires one of these projectiles every two seconds.
The mass accelerator on a human dreadnought fires one 20 kilogram slug every two seconds, each with a velocity of 4025 km/s. It is exactly as it appears by the codex entries and by the speech given by the soldier on the citadel to the new recruits.
Edit:
This is the youtube clip of the guy chewing out the recruits and explaining the mass accelerator on a dreadnought. Take particular note that he says, and I quote:
"it
impacts with the force of a 38 kiloton bomb"
Notice the word
impacts. That means when it strikes it's target, the projectile has the kinetic energy of a 38 kiloton bomb. As I said above, I crunched the numbers: a projectile massing 20 kilograms moving at 4025 km/s has 38.7 kilotons of kinetic energy (actually, kinetic energy is properly measured in joules. A 20 kg object moving at 4205 km/s has 162006250000000 joules of energy. That, however, converts to 38.7 kilotons). That means when the projectile leaves a dreadnought's main gun, it's going 4025 km/s. It will continue going 4025 km/s until it hits something. And then that something that got hit will have its day ruined.
