In my answer to the question which precipitated this one, I gave an estimated crew size of 250.
I have been unable to find a source for the Stargate wiki's numbers.
My numbers were WAG'd (Wild-Ass Guessed) as follows:
- Observed command and communications crew
- F-302 Pilots and crew
- F-302 support personnel
- Support staff (technicians, cooks, various extras doing extra-y things in the background)
- Security personnel.
First, the hard numbers: There are 16 F-302s. Each of them has two personnel responsible for in-flight activities (pilot and co-pilot). This means there are a minimum of 32 pilots. There must be backup pilots assigned. A reasonable safety margin would be 3 or 4 per wing, bringing our total up to 40 pilots.
Flying a plane (or space fighter, in this case) is the easy part. There is also a requirement for fueling, arming, maintaining, and controlling the ships themselves. In real air operations, this number is several times larger than the number of pilots. Given the cramped conditions aboard the 304 class, we can assume they carry minimal support personnel. I would estimate that they number perhaps twice the number of pilots (which would be hilariously low for something like an F-14. We have to assume that the 302s require much less maintenance than purely Terran craft). This brings us to 120 people, minimum, purely for the fighter wings.
Observed command staff seems to hover right around 12, possibly as high as 20. We routinely see 5-6 officers on the bridge during crisis (or normal operations). That being the case, there must be an equivalent number of 'bridge officers' for each shift (traditionally 3, though the late shift steps down the number of officers on deck). We can average this out to approximately 18, bringing us to 138 people.
Next we must consider the rest of the crew - the people who do things like cook food, clean the floors, run the engines, carry the big wrenches and clipboards, etc. They are the people who are ultimately responsible for keeping the entire ship flying.
Traditionally each officer would have a staff under them that does this grunt work. They have to cover 3 shifts (just like the bridge officers) and do a wide variety of tasks. I'd guess they are split into groups of 30, 30, and 10. It's likely that the technical staff of the 302 wing can be tapped in an emergency to support engineering, bolstering their numbers. This brings our total to 208 people, just over the total the wiki suggests.
It should be noted that none of these people are combat troops. They're engineers and pilots, janitors and cooks, commo officers and scientists. They aren't the folks you'll call to suppress the Replicator attack in Engineering, or to break up the fight in the galley.
That brings us to security.
Security personnel are harder to nail down, but given the levels of armed response we've seen on the show, I'd estimate that there are about 35 security personnel on board, split into three shifts of 15, 15, and 5. This would leave an adequate number to guard any prisoners or sensitive areas (if needed), be stationed for quick response to any area of the ship, and handle the armory. This brings my estimate to 243 personnel aboard each 304, rounded up to 250 people for simplicity.
EDIT: Found a potential source for that number.
About half-way down this page, there's an episode quote (From 'No Man's Land') which puts the number at 'around 200'.
McKAY: Good. Good. (They enter a room
and Rodney smiles at what he sees.)
Ah, now we're talking. How many more
of these do we have?
(Crewmen are unpacking sets of
KLEINMAN: Twenty in total.
McKAY: How many people on board?
KLEINMAN: In and around the two
This seems too low by my estimation, but I've not seen this episode. There may be mitigating factors which I'm not aware of (was this ship out with a reduced fighter wing? Had they taken losses?). In any case, a difference of 50 people can't easily be waved away in this apparent situation (seemingly a discussion of how much life support would be required)
Further searching brought me to this page which is from a wiki for a Stargate-based forum game (? I believe) called Stargate: The Next Generation. They don't source their numbers, either, but the descriptions are internally consistent and nothing contradicts 'more official' sources.
