In Starship Down (Season 4), the Defiant is hunted by two Jem'Hadar ships while hiding in a gas giant's atmosphere - at one point, the Jem'Hadar launch two "torpedoes" (never seen again, as far as I know) at the Defiant - the ship manages to dodge the first.

Now, these torpedoes are said to be closing "fast". The second torpedo is described as still closing - we don't see it hit - but the range is called out as it gets closer.
At 26:17-18, the miscellaneous crewman calls out the range as 100m - then 75m, then 50m, then impact at 26:27. In other words - it took about 10 seconds for the torpedo to fly 100m - or 36km/h (I'm sure one could estimate it more accurately, but who cares - its starting range and the time it hit are good enough).
(It's of course even worse when you consider the angle the torpedoes approached from)
The results? The torpedo didn't detonate. It did, however, show up wedged in the wall of the mess hall - where Quark and his Karemma associate try and disarm it.

What would the consistency of Defiant's armor be, really? Butter?
