Annoying statements on a variety of subjects:

Interesting idea, but neither of the submarines I was on did this.
We just threw the CO2 overboard, and got our O2 by splitting seawater.

Someone (specifically, Steven Bonneville) has misread those tables.
Fuel usage per ton of thrust is actually:
THRUST FUEL USE ...fuel per ton of thrust
Daedalus drive: 1.5 ton 0.00050 ton/hr. 0.000334 ton/hr
Fusion rocket 9.0 ton 0.00035 ton/hr. 0.00035 ton/hr
HEPlaR drive: 33.4 ton 0.02917 ton/hr. 0.000873 ton/hr

Well, no. Not really. Actually, in terms of fuel usage, it is
SLIGHTLY better than the fusion rocket. But it will never be used if
fusion rockets are available, unless you can live with small
fractional-G acceleration.

I thought of this a while back. Military vessels designed by me (as
theoretical exercises, since we don't use TNE rules) have fusion rockets
INSTEAD of Heplar.

I wish that whichever idiot gave GDW that definition of "point-blank
range" had kept his ignorant mouth shut...
"point-blank range" has absolutely NOTHING to do with height of the
gun above the ground. It has much more to do with the little known
detail that bullets, upon leaving the barrel of any gun, rise above the
line of the barrel by a small amount. Point-blank range is the range
that the bullet has dropped BACK down to the line of the barrel after
that rise.
Consider this, btw. If you use GDW's definition of point-blank
range, then almost by definition, an anti-aircraft gun of a given muzzle
velocity will have a longer point-blank range than an anti-tank gun of
the same muzzle velocity (the anti-tank gun sits low to the ground
(maybe 2 ft up), while the AA gun sits higher up (typically 5-8 ft, back
when we built AA guns))...

More thinly populated??? The SW have around 30 gigapeople in them,
all reasonably high tech. Regina subsector can only claim about 7
gigapeople, Rhylanor about 25, Vilis less than 10...
Plus, of course, the 50-200 ships per subsector is ridiculously low
BY TCS STANDARDS. In my game, Neubayern had several thousand warships,
New Colchis had more like 10,000 ships. All the Islands together
amounted to about the resource base of the SW, and collectively, they
could muster over 1000 warships in the 50,000T+ range, plus a few more
thousand in the 10,000-50,000T range, plus another bunch in the
1000-10,000T range, plus fighters (a total of over 100,000 fighters in
the Islands).
Besides all that, if you assume only 40-odd major Sword Worlds
warships, then the SW are in the same position the Islands were in when
the game began: any squadron of Tigresses could beat up their Naval
Forces all by itself. Frankly, any single Tigress could beat up the SW
Fleet if it is only 40 major combatants...
> It may be hard to imagine but it's consist with canonical material.
Do yourself a favour, and learn to ignore canonical material when it
is clearly pretty stupid. Regina may have had 10 400T SDBs, but if it
did, ask yourself "Why?"
There is no military use for them (any of Neubayern's Flower class
escorts (of which there were more than a thousand) could take all ten
SDBs at once.
There is no real civilian use for them (other than to let pirates
run amok through the Regina system) - remember that Regina orbits a gas
giant, and has a HUGE jump-limit to patrol - thye couldn't patrol it
adequately with ten of ANYTHING, much less SDBs that are no match for a
well-equipped pirate.
Customs cutters? They'd need more than ten, given that large
jump-limit, unless Regina has civilian traffic amounting to no more than
30-40 ships per day arriving/departing. And if that is all the civilian
traffic Regina has, then Regina's starport must be smaller than the port
of New Orleans...

There were designer's notes for FFW in one of the Journals...

Au contraire, mon vieux...Impy doctrine (which is frankly idiotic)
assumes that the battle for the gas giant between the enemy fleet and
your SDBs will be the crucial part of the defense of any system. It is
SUPPOSED to prevent the enemy from refueling before your Fleet can reach
the GG where they arrived, thus allowing you to pound them into bloody
paste before they can escape.
Admittedly, this isn't worth a pile of warm spit in terms of Naval
Doctrine. I point out, for those who are interested, that in only ONE
case in my TCS game did a Fleet jump in to a gas giant, rather than
arriving at the 100 diameter limit of the main world. And that one case
came because the attacker wanted the enemy to know he was coming, so as
to cause the enemy to be deceived as to the objective of the attack.
In all other cases, the ships jumped in using drop tanks (and aso
arrived with enough fuel to leave, if they had to), and arrived at the
100 diameter limit, thus allowing the target only an hour or two warning
before the attack began for a response to be formed...

Faced with defeat by Ihatei?!? What a concept!!! I suppose
Regina's ten 400T SDBs might be faced with defeat by Ihatei, if the
Ihatei could get in that far, but I find it hard to believe that any
_important_ Impy force could be defeated by the Ihatei...
Can someone out there design a TL14 ship of no more than 30,000T
that can fight off an attack by an Impy BatRon as long as there are at
least 100 of them present? I admit that using TNE rules, this is much
more possible than it was under either HG or MT, but it is still pretty
unlikely...
