Hello all,
      I've been quietly watching the TML for a while, and
been passing it along to members of my gaming group since
they have no net access. One of my group wanted me to post
the following information. Due to the length of this
posting, and the fact my local mailer cannot take long
messages this posting will be sent in 4 pieces. Please feel
free to reply either directly to him, or me. Thanks, and I
hope you find this of interest.

Howdy!
      Scott Kellogg is the name, Stephen Smith allowed me
to take a look at some of the MegaTrav discussion going on
and I was suitably impressed.  Neat designs you folks have
come up with.  So I decided to repay you all with a few of
my own.  I am afraid, I have no access to e-mail so you
will not be able to reach me very easily and there will be
long gaps between my having access to any comments to any
designs or ideas you might have but I would appreciate it

      Ok, are you ready for the question of the day?  What
is the rate of fire of missiles in COACC?  GDW's Air
Superiority allows ripple fire of 2 missiles per round of
the same type of missile.
      Well, that's against aircraft.  More than likely, an
aircraft would be destroyed by two.  OK, what about larger
targets?  If an aircraft went up against a larger target it
seems conceivable to me that systems would be convertible
to fire a larger number of missiles.  What specifically am
I talking about?  Fighter vs. Spacecraft.  Now anti-
spacecraft missiles weigh in at 50 kg for a normal missile
and 70 kg for a nuclear missile.  These missiles are
therefore capable of fitting on any hardpoint, on multiple
missile/bomb racks as a matter of fact, if you use all
available hard points plus two wing tip launch rails and
four fuselage launch rails (allowed for in the errata and
vindicated by the RAF Lightning and the A-7 Corsair II) a
total of sixty missiles are easily mounted externally,
(ignoring the bomb bay for the moment.)  That's two battery
rounds of a factor 6 battery, (TL-7) (at TL-13 it's factor
7).
      That makes an aircraft unbelievably deadly.  That's
the firepower mounted on a 1000 ton ship.
      Real life example:  in less than a minute the 'Six on
six test of the Phoenix missile system, six phoenix's
locked onto and fired on six targets in less than one
minute, by an F-14 Tomcat.  Since a starship combat round
lasts twenty minutes, I can easily see an aircraft firing
off a huge salvo of missiles in the time allowed.
      Game balance, you say?  Well... maybe, but you could
easily build a huge number of squadrons of cheap fighters
with Fusion rocket engines.  Also, with the enormous thrust
of the fusion rocket its very easy to build say a 12G
capable interceptor or even higher.
      More mundane question:  What are the penetration
values of the different air to air missiles?  Suppose my
players want to fire a radar homing AIM-7 Sparrow at a G
Carrier?
      Mundane question 2:  If the minimum size ship
thruster plates can be mounted on is 20 tons (Fighting
Shi*s of the Shattered Imperium), what about Anti-Grav
plates?  You can put grav modules on a 4 ton air/raft, Why
not grav plates?  The rules state that fractions of Grav
plates and thrusters can be built Personally, I think the
20 ton min is stupid.  It's torn apart a lot of my best
light fighters.
      If you ask me, I use
Book 2-Starships:  to design merchant ships,
Book 5-High Guard:  to design warships,
and Megatraveller to design headaches.

I hope you enjoy the designs,
                             Scott Kellogg

First, the Sparrow has a slight problem - you have to keep pointing at the
target all the time the missile is in flight, because it homes on reflections
of _your_ radar beam which has bounced off the target.  More modern missiles,
e.g. AMRAAM, Phoenix, Russian AA-10 contain their own radar transmitters.  It
might be worth incorporating some rule to deal with this in MegaTraveller; all
TL 7 radar guided missiles have this problem, so far as I know.

As for what its penetration value is, the short answer is not much.  For more
precise figures, someone will need to tell me how big the warhead is,
preferably by comparing it to a cannon shell.  (Is it equivalent to a 5cm
shell?  A 7cm shell?)  I can then get its penetration from the Striker
tables.  Also take note that air to air missiles have high explosive warheads,
and usually proximity fuses.  Aircraft aren't armoured much, so you don't need
a lot of penetration to hurt one.  As someone said in a previous letter, to
harm a G-carrier or other armoured vehicle, you really want to use an
anti-tank missile, e.g. Maverick, with a HEAP warhead.

Late versions had HMG instead of MMG (13mm guns replaced the 7mm guns).
Most versions had 4 autocannon, not 2.  I only know of 2 hardpoints on the
wings, not 4.  Some of the nice things which could be mounted on those
hardpoints were rockets (one 21cm tube on each, or racks of 24 5cm rockets);
extra fuel; and gun packs (2 20mm cannon in each).

I wonder if the outboard ones shouldn't be 2 hardpoints, with dual bomb
racks.  If other loads were carried, it was one unit per wing, e.g. the
37mm cannon used on the Russian front.

What you have described there is the anti-shipping version.  There were two
standard types: the pure bomber version:

Off:	Outboard hardpoints * 2
	Maximum internal stores = 1800 kg

And the fighter-bomber version:

Off:	MMG * 4 fixed forward firing,
	20mm autocannon * 4 fixed forward firing,
	Outboard hardpoints * 2
	Maximum stores = 900 kg internal, 900 kg external

Hardpoint loads can include extra fuel, bombs, or quad rocket racks.
There was also a night fighter with radar in the nose; later versions
had improved radar with a domed covering, which meant the MG's were no
longer there.

Not the Dam Buster; that was the Lancaster, and that modified.  Trials
were conducted with bouncing bombs on Mosquitos, but the weapon was not
used on Mosquitos in operations.
