was just using vector movement on ships. last night we had a game with a
couple of carriers and a total of 7 escorts,(9 vector arrows). Now if we
add arrows for the 10 Fighter groups
in play + a possible 6 more for the Missile carried by some of the
we have 25 vector arrows on the board at once. Also I think having, in
case, to write orders for each fighter group and missile would slow down
I'm not knocking the use of Vector movement for fighters / Missiles and
others (sand cloud weapons etc) and hope such development will continue
however the additional 'physical mechanics' that may be necessary to
represent them needs to be watched.
Integrating standard FT/MT rules for Fighters and missiles in games
the ships use vector movement has proved fairly painless. Yes in
fighters and Missiles ought to follow the same rules as ships but, we
explain it away with PSB. Ie.that these units use a different method of
propulsion, or in the case of fighters can achieve such high
factors that fighter movement as simulated in Full Thrust (especially at
24" move rate) is possible in the 'Newtonian' universe.

Would you apply some sort of proportional movement to the objects to see
at the point their movement lines crossed they occupied roughly the same
point in space?.
Example: As a Sand cloud can't thrust (and assuming they are launched at
the beginning of the turn) I can fairly easily predict where any
Sand Cloud launched by a ship will finish its move. Now supposing my
after applying Main Drive, Thruster or Rotation passes through the
of the cloud, will it automatically be judged for damage, if so then the
Sand Clouds area of effect is 3" wide and its vector x 1" long. If this
not the case then without proprtional movement its going to be difficult
judge whether a hit takes place.

I can see loads of arguments between players debating whether their ship

I like the idea of Sand clouds in Sci-Fi games (ever since Traveller), I
think a good use of it is as a way of simulating shields, ie a magnetic
field manipulating a cloud
of 'sand' around a ship, thickening it in the face of enemy fire and
opening holes to let your own weapons shoot, I suppose it would also
good anti-meteor or Interstellar dust defence (PSB+).

This missile would work fine the only cons being the need to plot and
another vector arrow. Would it attack at the end of movement or sometime

This makes a fighter group a Thrust 12 ship with 6 DP and 6 C Batteries.
I imagine it would be next to impossible to initiate a dogfight.

Why the above, if anything using Real Thrust for Missiles and Fighters
probably reduces their effectivness and flexibility.

Phil, I'm sorry if the above seems negative but we have been playing FT
with the Real Thrust rules for some time now and I know its difficult
integrating fighters and missiles into the same system.
I might be missing somthing major and about to be shot down in flames,
the above are just my first impressions.
