ARMOR
MODIFIER IN BABYLON 5

Why Earthforce armor is believed
to be 20x stronger than iron.
As the primary means
of defense in the universe of Babylon 5 is armor and not energy
shields, fans began to debate the question of just how strong was
the armor used by Earthforce in the Babylon 5 universe. As we had
no idea what Earthforce armor was made of, iron was used
as a base material to estimate the low-end armor strength
but as Earthforce armor was NOT comprised of iron, the question
as to how much stronger metals, armor and building materials would
be some 300 years from now became a question that demanded a some
kind of answer.
When this debate began
there were a wide range of opinions. Some said it was 35x stronger
than titanium - a number fans got from the "Star Trek the Next
Generation: Technical Manual." Some fans argued that B5 armor
was no more than 3x stronger than modern armor while others claimed
it was as much as 200x stronger. I had my own ideas about this,
but knew I didn't just want to pull some number out of thin air,
like so many others were doing. So, to get an idea of what kind
of limits I should place on my own work, I went to a mechanical
engineer - Mike Wong, the author of www.stardestroyer.net.
Now, Mike Wong did
not and does not endorse the use of armor modifiers and
has said as much in his web postings and in private correspondence.
My conversation with Mike Wong was not however to obtain
his endorsement, nor was it to tout his expertise to justify my
own work. It WAS however an honest attempt, on my part, to
place boundaries and limitations on my own work by consulting
an expert. Again - Mike Wong does not support
armor modifiers.
So that you, the reader,
can better understand how "I" came up with
the 20x armor modifier used for Earthforce vessels at this site,
and generally accepted by Babylon 5 fans world wide, and so you
can understand that Mike Wong did NOT endorse the use of
armor modifiers, below is a copy of the letters sent between Mike
Wong and myself with regards to this subject.

1.
Since your degree is in "Mechanical Engineering", I have a
good related question. If progression in this field continue
and we continue to refine and improve the way in which we
make new materials - how much more strong (using iron as a
base) do you hypothesize substances used in the construction
of space ships will be 300 years from now?

Less
than an order of magnitude. The strength of engineering materials
is dependent on their microstructural properties as well as
the intrinsic nature of inter-atomic chemical bonds. Unless
we can somehow figure out a way to make an entirely new form
of inter-atomic bond (not too damned likely),
or to produce and form neutronium (even
less likely), we will not see incredible increases
in material strength. The UTS (ultimate
tensile stress) for modern engineering materials
is, at best, two or three times better than what they could
produce A HUNDRED YEARS AGO.
For example, the UTS of ordinary malleable cast iron is about
340 MPa, and it was 340 MPa a hundred years ago. The UTS of
a high quality modern titanium alloy is less than three times
higher: about 900 MPa, and the pace of materials strength
improvement has been steadily SLOWING as the century has dragged
on. The first big area of recent improvements in materials
engineering is not in the area of sheer strength, but in aggregate
characteristics (looking at the overall
mixture of strength, hardness, creep resistance, and toughness).
The
second big area of improvement relates to forming- it's one
thing to make a super-strong material, but if you can't forge
it, die-cast it, rivet it, weld it, bend it, draw it, extrude
it, stamp it, mold it, or otherwise form it into usable shapes,
it's utterly useless.
If I were to look into the future, I would assume that they
have a material which has a UTS equal to the strongest material
known to man, toughness equal to the toughest material known
to man, creep resistance equal to the best modern high temperature
engineering materials, and most incredibly of all, they can
easily form it into whatever shape they want. That last factor
is HUGE in real world engineering, but most sci-fi buffs have
no idea.

Again - Mike
Wong does not support armor modifiers. What I took away
from Mike Wong's comments suggest that armor strength would be -
in general - less than an order of magnitude
greater in the era of Babylon 5 compared to today. Now there are
obviously a lot of factors to consider. We've got:
- strength
- hardness
- creep resistance
- toughness
These features are mutually
exclusive, because you can have armor that is physically strong
but has little in the way of heat resistance and vice versa. While
we have all heard buzz words like plasteel and morbidium cast about
in the Babylon universe we still have no clue as to what these materials
really are or their characteristics; we simply don't know what they
use for armor in Babylon 5. Regardless, what "I"
tried to do with the armor modifier was create a general,
generic armor modifier that everyone can understand.
B5 has mentioned things
like beryllium alloys and elements not even on the periodic table
such as morbidium, a fictional alloy used in the construction of
PPGs that is harder than diamond. This being the case we must take
what we know and make a logical estimate as to how much stronger
armor will be in the future.
So, rather
than fidget with trying to pin down the strength of fictional
elements, we will instead take our base element - iron - and increased
it by a single order of magnitude. We then increased a popular metal
used for armor in the here & now, in this case titanium, and increased
that by an order of magnitude as well. This gives us our base material
of iron multiplied by ten (b * 10 = x), and our modern armor material
of titanium (3b * 10 = x). Where b = 1 our base of x for the first
equation would come out to be 10, and for the second equation we
would have an armor strength of 30. We then compromise our two figures,
we get "30 - 10 = 20" and that gives us an armor strength
of 20x or 20 times the strength of our base material of iron. And
this is what...?
Less than an
order of magnitude relative to titanium! - or
67% stronger than modern armor used by military forces today.
As you can see the 20x
modifier is not some wild guess, generalization, or random number
pulled out of a hat. The 20x armor modifier is a reasonable estimate
based on our current state of development... a number that is LESS
than a single order of magnitude greater than titanium, a conservative
number for a science fiction universe in which there are no shields
or deflector screens and armor is a ship's only form of protection.
NOTE: This is
a generic number. It does not mean that B5 armor is 20 times stronger
than iron in all respects (strength, hardness,
creep resistance, toughness). It is a round number
and an educated guess as to how much stronger some
of these features may be in the future. Whenever possible, it is
better to use the base figures and, obviously, the 20x armor
modifier will not apply to kinetic impacts or explosions.
While some have argued
that any armor modifier used skews observational results with regards
to the effectiveness of an energy weapon - an opinion I just
happen to share - I also beleive that in some cases
where we do not have a tangible incident with which to judge
the effectiveness of a weapon, an armor modifier may be needed
and can be used to help estimate the scope of a weapon's
effect when no other "real world" example is available
with which to make a more accurate estimate. A perfect example of
this is the weapons of the Minbari and Earthforce.
At no time have we seen
the weapons of the Minbari War-Cruiser or Earthforce Omega class
Destroyer used against a real world object like an asteroid; weapons
were only used against other ships, forcing us to make estimates
based only on those events. Estimates with regards to energy weapons
based on damage inflicted upon a vessel where the observer used
iron (a metal used by man for thousands of years)
as a base material, providing us with a low-end estimate
that we know could not be wholly accurate with regards to the given
technology level of Earth Alliance or the alien races in the Babylon
universe as their ships were not made of iron... under those
circumstances the use of an armor modifier can be understood.
So, with the lack of
real world events to observe and draw upon to establish a solid
and accurate low-end estimate for the effect of something like a
laser fired at a real world target like, say, the asteroid vaporization
in "Star Wars: The Empire Strikes Back" or "Babylon
5: A Call to Arms", for many fans an armor modifier became
necessary in order to arrive at, what they perceived to be, a more
accurate conclusion.
In an effort to make
sure that any armor modifier used was within the scope of believability,
I established the 20x modifier for energy weapons. Armor estimates,
when used judiciously can improve upon estimates based
on ship-to-ship combat but - obviously - real world events
like the destruction of an asteroid will provide a more accurate
figure as no armor modifier is required.
NOTE:
Michael Wong does not support armor modifiers. His comments
were used by myself as a means to establishing an upper
limit on my 20x armor modifier. This armor modifier was
not established nor endorsed by Michael Wong.
