When faced with this evidence, only two conclusions are possible.
1. Klingon shields are far weaker than Federation shields.
2. Klingon shields (and maybie Romulan) shields really suck when it comes to stopping K.E. attacks, compared to Federation shields.
#1 works in early TOS, if "Elaan of Troyius" is an indication. But by the time of TMP, it's a bad example. If anything, the
K't'inga cruisers had shielding roughly on par with a refit
Constitution: know how the E was only expected to take one hit of the plasma weapon, and the second would destroy her?
Well, the Klingons took a hit that didn't destroy them, too. We saw this from the message the Federation space station received, as
Amar took a hit, violently shuddered, and "continued their attack."
That doesn't necessarily mean perfectly comparable shield protection, but it's roughly the same...it wouldn't vary by as much as 10 times.
Later on, in TNG, we saw
K'Vort battlecruisers take on an unprepared
IKS Bortas (
Vor'cha-class).
Bortas took many dozens of hits, just as the heavily militarized E-D did in "Yesterday's Enterprise" from 3 similarly-sized ships (one of which didn't focus her attack on the E-D until a sister ship was destroyed).
So again, we have a ship that's actually smaller than the Federation's best--the
K't'inga at 214m length vs. the Connie's 305, the V'C's 481m vs. the GCS's 641--that sports roughly comparable shields. A true match in size should at least give Klingon shields parity with Federation ones, if not somewhat better shields overall.
Number two is more likely, but I also think it's deceiving. I'm not entirely convinced that the Jem'Hadar simply overpowered the Klingon shields. They certainly *were* shielded craft, and I don't buy this appeal to ignorance about offscreen fire depleting said shields (as RSA suggested on his site)...BUT a weakness to kinetic energy is only one possible explanation why the craft were able to plow straight through.
I think it's equally possible that Klingon shields simply can't stop Jem'Hadar shields. KIM that shields and tractor beams seem to be closely related technologies, and that Jem'Hadar shields are impervious to tractors ("The Search," I think). It's no big stretch to think if they're immune to tractor beams, they could pass through an enemy's shields too.
(Someone will ask me why I think the two are closely related technologies. I'm in a pinch, so suffice to say, "Way of the Warrior.")
That does not adequately explain why
Scimitar was so badly damaged by E-E's impact, which probably would've imparted roughly the same energy to Scimmy as the far less massive, but much quicker Jem'Hadar attack ships nailed
Vor'chas with. Obviously, the Scim. HAS "particle shields," because it stops photorps. And even though we didn't see its shields flare (which, IMO, we should've, even if they failed instantly), I think it's stupid to suggest Shinzon just left the damn shields down altogether.
So, we're back to the weakness to physical impacts thing.
If the evidence says Klingon ships are destroyed by slow moving light attack craft without so much as a shield flicker, then so be it. It should not be ignored, however, that Federation shields have survived worse, much worse. Infact, it becomes kinda silly. For example, The J.H. attack craft almost certainly had the standard trek mass lightening fields active.
Actually, those ships weren't moving what I'd call slow--the ones that plowed through
Vor'chas were doing better than probably 900m/sec.
Even *after* they tear through the V'C's hull, it takes them less than a second to cross the thing's length, which would slow them down significantly. Estimating their velocity based on that (481m/sec.) would be a lower-limit.
As for mass lightening fields, I sorta agree, but we don't know that the Dominion uses such technology, nor do we really know anything of their power sources. As far as I know, mass lightening for impulse drives is never mentioned onscreen; we can infer its necessity from what we know of ships' power outputs, but those are Federation ships. We honestly don't know enough about the Jem'Hadar to make such a claim. While I think it's likely, it's an unknown.
On top of that they moved slowly. But the nacelle that hit the Enterprise-D was not only larger and faster moving but could not have had mass lightening fields up and running! The diference in K.E. and momentum surely was staggering. And it comes down to this: One shield shrugged a large attack off without mentioned damage, the other failed (or didn't oppose it, or something) after a small attack without a flicker, yet both can handle similar punishment from energy weapons.....
I see what you mean, though again, those attack ships were zipping along at a nice clip...even after plowing through the Klingon ships' hulls, they exited the ass end of the things in under one second, barely slowing down. Their initial velocity must therefore have been higher.
As I also mentioned, it's possible that the Jem'Hadar ships provide a complicated example in rating Trek powers' kinetic shield strength. We've never seen a Jem'Hadar ship nail a fresh Federation cruiser like that (
Odyssey was in bad shape, and might not've had shields up at all after rerouting shield power to her phasers, as mentioned in the episode's dialogue). Klingon shields might be as effective in stopping roughly equivalent levels of kinetic energy, but they cannot block whatever it is that makes up a Jem'Hadar shield--that which Federation tractors couldn't lock on to.
That's just a guess based on the little we know of Jem'Hadar ships, of course. It's far easier to conclude a weakness to kinetic energy is what we're looking at, and that's something certainly not without precedent among the alien races (Son'a, Klingons, Reman/Romulans, Jem'Hadar themselves, Krenim).
