It's a little fluff piece called 'Adeptus Astartes Fleet Capabilities in the Gothic Sector, Obscura Segmentum'. Which is exactly what your asking, I believe. I'm not going to copy the whole thing, it is quite long. A whole page in fact. But I will quote the last paragraph for you.

Spoiler:

In conclussion I would surmis that the Adeptus Astartes commands powerful fleet forces, capable of overwhelming even a heavily defended system. In a fleet action they would be at a disadvantage in comparision to Imperial vessels due to their special adaptations for planetary assaults. However it is hard to imagine that the Adeptus Astartes would accept a ship to ship fight on any but the most favourable terms, instead operating against shipping lanes, dock facilities and other vulnerable assets. I only pray that they remain on our side.

So, your half right! IMO

I don't, but that is indeed interesting. Thank you very much. Could I ask as to whose opinion it is?

You are very welcome.
unfortunately, it doesn't give a name. He titles it to 'Honoured Lord', which could be enybody. But he does state, "Their repeated implication seems to be that they are more likely to have to fight against Battlefleet Obscura then alongside it, hence their interest in joint fleet operations is minimal." Which seems to indicate he is an agent of the Imperial Navy: Battlefleet Obscura. That's just an assumption on my part, though.

1. With a theater of war 9460528.4x 10 to the power of twelve kilmeters across, every engagement is an isolated engagement. The fastest jets can cross the world in an hour, whereas even with warp travel it could take generations to cross the breadth of the galaxy.
Except often there are navy ships nearby or already there (such as Cadia) or if the IG has to be brought there, then of course the navy is involved...

2. -_- you managed to miss it AGAIN. TBH I don't even care. I won't try anymore. Forget this point.
Which points?

3. If they happen to be there, they won't stand Idle. But astartes take full control of defensive and offensive boarding actions, and even captain their own ships. Unlike Guard. Who don't even have ships. And if you love US military analogies so much, I'll use it to describe your logic. If the USMC and US Army went to war, you think the Army would win because all the other branches would side with them by default and all gang up on the marines.
That's a rather poor analogy there. The US marines aren't an independent organization that answers to practically nobody, they're heavily reliant on other services and are part of the same command structure. The Space Marines would be more like the ATF or Secret Service in terms of their relation here, completely distinct organizations that have little or no connection operational link to the others. What you are describing would be more akin to the IN fighting the IG.

4. Except it is not a rectangle. It is a cylinder.
Ok fine, we'll do it that way. Volume= (3.14)xRadius^2xHeight.

So we get 3.14x50,000^2x1000=7,850,000,000,000 so 21.5% smaller than the way I did it before, not a huge difference on the scales we are talking about.

And 200x200x200 (one sector)
Apparently somebody doesn't know how cubic measurement works. 200 cubic lightyears means you multiply 3 others numbers to get the 200 Cubic LY, something like 5x4x10. That's how cubic measurements work. If something says its 200 cubic *whatever*, that doesn't mean its 200x200x200*whatever*, it means AxBxC=200*whatever*.

which equals 8,000,000 (8 million). So in your estimate, which takes the entire galaxy, Imperial and non Imperial, and overstates it sizes due to a basic geometrical failure on your part, could only contain 6250 sectors. 10's of thousands my ass.
Or it's a basic failing of mathematics on your part.

Just to back myself up, Check the wikipedia numbers on the Milky Way's volume listed by cubic light years. It looks identical to that number I just calculated here a couple lines up doesn't it? Using that number of 7.85 trillion cubic lightyears divided by 200 cubic light years per sector, we get 39,250,000,000 (just over 39 billion) possible sectors.

Let's assume only 1 in Ten Million sectors has a sector battlefleet, 1 ten thousandth of 1% of the galaxies possible sectors, that still gives us 785,000 Sector Battlefleets consisting of dozens upon dozens of vessels, or almost 800 sector battlefleets per Space Marine chapter. Tens of thousands of sector battlefleets all of a sudden doesn't sound so ridiculous anymore does it?

6. Doesn't change the fact that there literally would be absolutely no Mechanicus of Mars without the IF. At all. None.
Which is 100% completely irrelevant to anything being discussed and highly unlikely given that the Mechanicus had many other worlds at the time as well.

Bit late, but here goes:

1. Okay, so if you are talking about the single largest theatre of war in the entire galaxy (Cadia) there are going to be both organisation. Doesn't mean every planet in the galaxy guarded by guard has naval support. Want examples?

2.

All the rest:

NOT 200 cubic LY. A sector is a cube whose sides measure 200LY. Therefore, 200x200x200.

Yeah, about 40,000 times larger than you thought it was. awkward?

My math messup was ALMOST as bad as yours, i missed two zeroes. either way, due to the Imperium controlling a mere fraction of the galaxy, They absolutely do NOT have tens of thousands of sectors. They have one million planets. There are 500 billion in the galaxy. That means they control 1/500 000 of the galaxy (average density). That would (using average density) give them 15 700 000 cubic lightyears, or just under two sectors. Uberfail GW writers strike again!

That girl-lieutenant wanted some space marine d. Not gonna lie.

The interesting thing about having a smaller crew means that a ship is actually *more* vulnerable to damage. Specifically, because there aren't as many damage control parties.

Concerning a Strike Cruiser, yeah, if it gets within boarding range, bad things will ensue. However, from my perusing of the Battlefleet Gothic books, it just doesn't seem that a Strike Cruiser is categorically superior to a IN light cruiser. I mean, nothing is exactly screaming "monkeystomp time!" like the difference between a Dictator cruiser and a Dauntless cruiser (110 points, and the Dictator would kick in the Dauntless' teeth). But, again, if a Strike cruiser tries to punch above its weight and go up against a full Cruiser, it looks like things would go badly for the Strike cruiser. By itself, of course; when you introduce screening elements, things become more fluid.

Less crew quarters=more redundancy.

Plus they have about 3 1/2 gakloads of serfs aboard the ship.
