It must be at least 330 million, given population of Earth alone. At any rate, 5% of 300 million is 15 million, not 3 million, so I assume you meant the 1%. A couple hundred thousand here or there is inconsequential.
I ran the numbers with 95% infantry/support, 5% fleet crew, then switched to 99% and 1% to cut it back - and while I remembered to edit the 95% to 99% and 15 million to 3... I missed the 5% -> 1%. So yes, it was a typo

3) "So why all the crew?" Dreadnoughts function as mobile command centers and as suck are filled with people you don't want to die. For that reason, you would up the engine size and barrier capacity through the whazoo, and stick all your support crews on there, while keeping the minimum operating crews on your nowhere-near-as-tough cruisers
I have mostly considered dreadnoughts as primarily offensive ships. Their attack power is significantly higher (as you noted in the snipped part), but I’m not certain their defensive capabilities scale equally. In this sense, I’d think it would make far more sense to distribute the essential functions with redundancies between cruisers. They’re more agile, disproportionately more defendable, and there’s more of them.
But, you may be right.
I based it on a combination of what you see in the Battle for the Citadel, and the explanation of how capital ship weapons work in the Codex: Namely that while cruisers one-shot each other with a direct hit, the Destiny Ascension weathers a barrage from multiple cruisers without its barriers failing.
- Mass Accelerator power increases linearly with slug size and barrel length (and thus ship length).
- Barrier strength increases with ship power generation, which in turn increases linearly (at least) with ship tonnage - which increases with the cube of the ship length.
Okay. So lets go with something like this:
Frigate: 200m
Cruiser: 600m (According to the codex, that's what the Alliance builds)
Dreadnough: 900m (Everest class)
The Dreadnought has 1.5 x 1.5 x 1.5 = 3.4 times the mass and power generation of a cruiser and 1.5 times the barrel length. Assuming that it can then fire a slug 3.4 times the mass of a cruiser, this makes its main gun... 5 times as powerful as a cruisers, give or take, with triple the barriers.
If we bring the Destiny Ascension up to 1200m and arbitrarilly throw on +25% engine power (for superior Asari tech and weird design), we work out at 2^3 x 1.25 = 12 times the barriers (about right) and 8 x 2 = 16 times the main gun strength of a cruiser (triple that of an everest class dreadnought).
And that... would produce something like the commentary (on ME1 first approach to the Citadel) and cutscene of the battle for the citadel.
But I'm just speculating withnumbers here
