Amarr ship designs incorporate more automation than many outsiders assume due to the sheer size of their fleets and their wide distribution across the Empire. While the Amarr military has legions of personnel, the vastness of the Empire and the requirements of the Navy mean that automation is essential, even on ships where there are complementary slave contingents.
Caldari vessels are noted for their advanced technology, but many overlook the fact that, with respect to crew complements, the Caldari Navy and corporate security forces are rather old-fashioned. Caldari society is highly militarized, and this, together with the relatively small size of their fleets compared to the other empires, has meant that they have never been under pressure of crew shortages. As a consequence, crew-substitute automatic systems are less in evidence in typical Caldari designs.
The Gallente Federation may have a large population but the average citizen is not inclined to join the Federal military. Moreover, the pressures of the first Caldari-Gallente War led the Federation to invest heavily in automation and military drones. This tendency has continued ever since, and the Gallente Navy has always ensured that their vessels are highly automated so as to allow them maximum use of their relatively tight personnel pool.
The Minmatar have never suffered from lack of numbers, even while so many of their brothers and sisters are enslaved by the Amarr or living in the Gallente Federation. Their excellence lies in mechanical devices but less so in automated systems. As a result, the Minmatar use large numbers of crew on their vessels. Some of the more advanced designs may be less rigid in this regard, but nearly any Minmatar ship will seem crowded compared to its contemporaries of other empires.
I'm writing what I find to be a very exciting guide to roles and ranks in the Caldari Navy, and I hope to do one for the Federation and Amarr ones too. I was thinking, from the above, on the division of officers and crew, and what they do, onboard EVE ships.
If Caldari ships are old-fashioned in terms of structure, and have a low level of automation (Minmatar too probably), then they are likely to resemble a modern-day warship, that is, having individual crewmembers maintaining deck operations (loading guns, damage control etc.) and operating the warfare systems at the ship's combat information center. They will have a cabal of officers overlooking them.
However, if the Federation Navy is more automated, then it may have more in common with the Star Trek way of doing things, that is, a greater focus on officers than crewmen. For example, IRL navies, there is no such thing as a "Communications Officer", but comms technicians instead. Weapon systems are operated by a crew of enlisted personnel and so on. However, the Feds may have a single officer trained to oversee a certain system (Tactical or Gunnery Officer for weapons, for example), and see that all things are running smoothly, and operate them on the deck officer's command. In addition, as opposed to having multiple engineering officers for, say, astronautics and weapons, they might just have one.
For the Amarr...how many of the general crew are going to be slaves, and how many are going to be professional? The officers in charge are obviously going to be professional, and likely to be exclusively True Amarr...I think that is a debate for
Lou's thread.
