I've only seen the movie once, so far, but the design of the Yorktown station seems to be totally absent of any practicality.

enter image description here

The vast majority of the station is open air. That doesn't seem smart. And rather than having docking ports at the perimeter, ships fly into the superstructure down long passages towards the center of the station (under fountains, and park areas). Again, this seems to fly in the face of common sense. Also, I understand they're using artificial gravity, but wouldn't that be incredibly difficult to maintain considering the every-which-way direction of the construction. If there is any advantage to this design, I'd love to hear it.

    Did it have a large artificial atmosphere? Atmospheric effects are responsible for the color of Earth's sky.

    As much as it pains me, this is off-topic as asked. Questions about the benefits of using an airsphere instead of a free-floating space station are better asked on Space:SE or Worldbuilding:SE.

    @Valorum Why not edit the Q? I just came back from seeing the movie and I thought Yorktown Station was over the top, too. Why did the designers design it that way? Gargantuan advance over DS-9!

    “The vast majority of the station is open air. That doesn't seem smart.” Earth has a similar problem. Nice job, God!! Commented Jul 31, 2016 at 17:40

    The vast majority of Federation designs are absent of any practicality! You think the "neck" section on the Enterprise is there to improve structural integrity? They've solved poverty, disease, war and world hunger, they get to make things pretty now! Commented Aug 4, 2016 at 22:21

In the introductory scene, we see other characters marveling at the station with only McCoy concerned about it;

McCoy: [It] Looks like a damn snow-globe in space just waiting to break!

The station is brand new, and apparently a technological marvel. Spock points out that it was constructed to avoid showing favoritism to new Federation planets in that area. It appears that the station may have been as much an advertisement of the Federation's technological ability as it was a major spaceport.

In terms of its actual durability/engineering, if you watch the scenes with the attack, you'll note that the swarm attack the docking ports, not the surface, indicating that it may be heavily shielded/armored. With a powerful shield like that, the internal structure can be left "open" without apparent issue. Presumably this could also allow for later expansion into the open space.

In terms of artificial gravity, there is that sequence with the 'gravitational slipstream'. It seems whatever artificial gravity tech the station uses works along arcs, possibly the same arcs that the arms/rings are built along. Just like warp physics defines the shape of starships (nacelles, saucers, etc) in Star Trek, whatever gravity technology they use on Yorktown may well have dictated its design.

In Summary

  • The station is brand new, high technology.
  • The station's shell is shown to be very tough/resilient.
  • The artificial gravity they use appears to operate along arcs or curves, likely influencing the structural design.

According to Word of God the station serves as a diplomatic hub for newly-inducted species in that area of space, who can send delegations of people to meet the rest of the Federation. The technological marvel/beauty of the station could well influence them and other species considering joining.


When you think about how advanced Federation technology really is... the Yorktown starbase is really not a big deal to design and construct (in a short span of time). They could have easily made just 1/8th of the station and then reproduced it in a spherical fashion with automation doing everything (which could have taken days or weeks - given how automation is hundreds of thousands of times faster and better than people in reality, and Trek would be progressing faster than exponential by the 23rd century giving them far superior capabilities).

Any advanced space culture would have to rely on automation for construction in space (considering its very dangerous and manual labor in contrast is too slow and inefficient).

The Federation in the 24th century (prime timeline) might have had the Yorktown station as well for all we know. There's no reason to think that the station wasn't already in existence before the events of 2009 Trek movie.

As for it looking a lot more advanced than DS9... well, DS9 is Cardassian in origin, and a mining station to boot. Starfleet did have the mushroom type starbase orbiting Earth in the 23rd century (and that was pretty big too)... and for all we know, it could still exist in the new timeline (seeing how Earth's orbit is really, REALLY huge and you could easily place thousands of ships in orbit without seeing them from a distance).

Though, it could also be that due to events of temporal cold war during Star Trek Enterprise, certain changes in Starfleet designs could have ensued (the destruction of the Kelvin could have affected a pre-existing superstructure in orbit of Earth - unless it didn't and Starfleet merely chose to make a newer starbase design that would co-exist with the mushroom one and the mushroom design might have been phased out eventually).

The Yorktown does make a good sense as a staging area as well as a diplomatic hub for introduction to the Federation way of life (plus it probably has decently sized and dedicated construction facilities for creation of ships and fleet deployments - so I doubt its only purpose is for diplomacy [although it is more than likely its primary function given how the Federation works) - like every other piece of SF technology/hardware/ship, it seems multi-factorial in purpose - and that's good).

But we also have to keep in mind that the Federation is likely more than capable of making mega-structures... its just that they likely have little need for such things given they usually do more with less (technical efficiency) without thinking about 'money' - its more to do with doing things in abundance sustainably with little to no damage to the environment while using state of the art science and technology - something that Capitalism doesn't/can't do at all since in Capitalism, focus is on 'cost efficiency' and SF technology reflects technical efficiency instead).

At any rate, the design of the station (aesthetics) could partly be there for the purpose of impressing potential alien races that might consider joining the Federation, even though it may not look too 'logical' - and to the Federation it may not matter as they could have reinforced it really well either way.

Maintaining artificial gravity, as well as atmosphere could be contained to the stations 'arms' and not throughout the empty sections of the structure (after all, you would want to do things efficiently, so there would be no point in filling the entire spherical area with air), while the blue haze could be a physical transparent structure (possibly made of incredibly tough material for additional protection that was lined with tough shielding) for generating daylight and giving an illusion as if you're on an planet. And it is possible that the stations arms also produce an atmospheric effect of their own to hide the outer space even more.
