So I've watched pretty much all the Star Treks and from what I've seen, Star Trek officers don't wear any protective gear! Why don't they wear any kind of armor like the Klingons? Is it because the weapons are so powerful that it doesn't matter if you wear armor or not? Ex: You're shooting antimatter so it doesn't matter if you have matter type armor?

But then again, the Borg. They have personal shields, but everyone else doesn't for some reason. Why can't Geordi or Data figure out how to create portable force fields by putting down things similar to those power poles placed in a triangular formation when they need to teleport into an "interfering" atmosphere?

    Worf makes a personal shield out of his communicator and spare parts from the late 19th century...so it doesn't seem like a matter of "figuring out" how to create one, but rather they just don't.

  • If the video games were canon, then we could say they often used personal shields and armor. But only then.

    The Star Trek movies had security officers in body armor. en.memory-alpha.org/wiki/… Apr 17, 2014 at 23:03

  • A better question would probably be why they beam down the entire command staff of the ship instead of dedicated security personnel, scientists, and medics. And in addition, it has the same answer: because in fiction, coolness is preferable to practicality.

Given that the primary purpose of Star Fleet is peaceful exploration and all that good stuff, I'd be willing to bet that the primary reason they don't wear any sort of armor is that it goes against that particular mission statement (e.g., "Hey dude... if you're here to talk peace, why are you wearing that big ol' suit of armor?"). Klingons are a battle-oriented people, thus they're always ready for battle. Same for the Borg: They know they're not the most popular kids on the playground, so they dress accordingly.

This seems like the best fit given the nature of the various races that wear armor: The Hirogen, the Cardassians, the Jem'Hadar, etc.

    This answer makes sense. The Federation is out on Peaceful missions. However, when they do know they are going into a hostile environment, they still don't gear up... Oct 24, 2012 at 21:38

    You're right, this is very true. However, I think that in most cases, they err on the side of peace. It doesn't really make a lot of sense given what we as the audience have seen over the various series. On a side note, there is the MACO unit from Enterprise; granted, there's no further evidence of their existence beyond that, but it does show that Star Fleet is capable of military-style activity.

    What about that one episode where they were a warfaring organization in an alternate universe? Or any of the Mirror Universe counterparts?

    For those cases, I'd say that it's probably just straight up arrogance with regards to their abilities. Mar 14, 2014 at 9:12

    This may be good answers in general, but I don't think it explains why they still do it when the situation is clearly dangerous. or example, in the episodes Descent (6x26 and 7x01), almost the entire crew were sent to the planet on foot to find Picard who was abducted by Borgs, despite the obvious dangers. Luckily of course, the Borgs only killed off minor characters :)

Personal shields we see

Personal shields are not outside the realm of technological knowhow in-universe. La Forge creates a subspace isolation field (TNG:Timescape), however, this also reveals the flaw in that technology, they appear to be fairly weak fields (La Forges is easily disrupted by the alien).

The other place we see personal shielding is in TNG:Lessons where Lt. Commander Daren used Thermal Deflector Units to protect the away team from the firestorms on Bersallis III. Again, even though the deflector units were reenforced with energy from hand phasers two team members were still killed when their unit failed.

(Noted below is also Alt-Spock's use of thermal protection armor in the volcano)

It's about the power

These examples point to a plausible reason we don't see personal energy shields: power consumption. Generating a field may be easy but generating a field sufficient enough to defend against highly focused energy weapons or other harms is difficult.

What about the Borg? It's quite plausible that the Borg's advanced technology and cybernetic components allow them to generate the necessary energy to support such technology (it's worth noting that the Borg also don't employ energy weapons in close combat situations so there may be a tradeoff).

In all honesty, though, it seems quite likely that the weight and complexity of such personal armor or shielding would be worthwhile when combat was expected. However, we never get to see such "infantry" style combat in Star Trek.

Did we mention "We come in peace?"

Our Trek heroes are explorers, not soldiers, so to dress in heavily armed attire would be uncharacteristic. It's hard to believe "we come in peace" when you're wearing heavy armor. Klingons, however, are soldiers that prefer hand-to-hand combat so their armor is entirely appropriate.

This would likely be reflected in the type of technology researched and implemented so it would have less of a presence in the universe. It seems likely that Starfleet would have learned the lesson our current Earth has not yet learned. Highly militarized personnel tend to result in more violence and escalation of volatile situations.

The Starfleet Pajamas may be a lot of things but they certainly wouldn't feel intimidating.

Pattern Enhancers and their variable use

The questioner also mentioned the humble pattern enhancer, often use for variable purposes within the Trek universe. It does not seem to have been used for shielding purposes (although it, or a substantially similar device, was used in Time's Arrow to allow phase shifting in the alien cavern).

Portable Energy Weapons > Portable Energy Shields or Physical Armor

In short, your supposition seems accurate: Energy weapons commonly employed within the Trek Universe make it difficult to provide effective individual shielding (physical armor or energy shielding).

This actually might make a little "sci-fi science" sense, if you consider that even the Borg had to adapt to the energy weapons being used to effectively block them. It seems likely that in order to block all of the possible variations of energy weapons would have proven too difficult or energy intensive.

I'd like to add a small caveat: it does seem likely that special militarized units within Starfleet would find it worthwhile to find specialized implementations of energy shielding (a "burst shield" or a "assault shield" like the literal police/military shields). However, these would seem to be specialized requirements and outside the realm of normal training within the peaceful exploration mission of Starfleet.

  • How about protective vehicles such as an armored shuttle?

  • Honestly, this I know less about, might be better as another question. Shuttles do get covered but no mention of armor is made (shields are standard, though), the same goes with Runabouts (which are more heavily armed and protected than other shuttlecraft we see), even the Delta Flyer has a standard hull. The SC-9 that Admiral Janeway brings back from the future to rescue Voyager from the Delta Quadrant does have ablative armor but it's from decades into the future. In other words, if you are speaking specifically about physical armor, it's unusual for Starfleet.

  • @user69715, honestly that question also asks about personal armor so it would seem to be a dup. Vessel armor hulls would appear to be different to me.

There is also the Life Support Belt, but they were only on The Animated Series and some of the games. (Canonicity disputed)


Starfleet officers are exploration oriented... though, you would think that their uniforms would be comprised of superior metamaterials that are easily programmable and have fully integrated technologies into the fabric itself... by the 24th century, this type of technology should easily be possible.

No need to have a commbadge or a tricorder when your entire uniform comes with a plethora of networked subspace mini-sensors.

At any rate... personal weapons are indeed quite powerful to the point where they would probably render any personal protection useless. Even in the case of armors resistant to phasers or disruptors, those personal weapons can be modulated/adapted to penetrate those armors eventually.

We have seen in early TNG some security officers on Enterprise-D wearing protective armor, indicating it might be disruptor/phaser resistant. And who knows, maybe later SF uniforms are indeed designed with other materials that make them much more resistant to energy weapons.

As for personal force-fields... those should be powerful enough to protect against energy weapons actually as in DS9 prior to the Dominion War, we have heard admiralty talking about widespread distribution of personal-forcefields.

The instances we've seen personal force-fields fail was not because of power generation, but inherent instability of the environment they seemed to have been protecting the user from. The units LaForge rigged were done on the fly... they weren't specialized units that protect against temporal displacement... and, considering he had to rig them relatively fast, they did the job splendidly for protracted periods of time. Plus you have to keep in mind that you are protecting a user from a temporal field which is keeping the environment moving through time at an imperceptible rate... and there are probably variations in the temporal field that LaForge didn't account for which would limit the time you can spend in such an environment.

Plus, when Worf fashioned a personal force-field from a comm-badge, power generation was a problem yes, but only because he used a comm-badge and not an actual power cell for a personal shield.

In the case of Voyager... we've seen Seska using a personal force-field to enter a space inside a Kazon ship that was sealed off by Subspace force-field. Again, power generation wasn't the issue... she was manipulating sub-space as it was noted by Janeway, and that's rather delicate work - especially when you are also working with a radiation field that's excessively dangerous).


They do (inconsistently)

There are actually a few instances where we do see Starfleet personnel wearing body armour but it seems to be a question of personal choice (or possibly that differing ranks have different requirements to wear armour) since we also see people in the same scenes not wearing armour, usually when they're a ranking officer.

Regarding armor, the real question is why the Klingons, Romulans et al continue to use it when every Tom, Dick, and Harry* can phaser them to death in a single shot anyway. With the possible exception of the Jem'Hadar, I don't recall anyone's personal armor ever actually doing them any good on any of the shows.

As regards environmental suits, or at least more rugged uniforms, that I can't explain in-universe. (I can give you the out-of-universe explanation, which is that more costumes and props = more money that they didn't have.) Presumably the sensors can generally tell them if an area will need full-on isolation suits or not, but even so some basics like a hat, gloves, and decent boots or hiking shoes would seem to make their surface trips more comfortable, to say nothing of more productive.

*Voyager really needed a secondary character named Richard for the sake of this joke, but sadly I don't recall any existing.
