In the context of mechanics ported from T5, no idea.Looking at T5's firm points.
The question occurs, what id Short range in CT?
T5 B2, p53:
A Firmpoint will accept any mount which is less than one ton (mounts less than one ton are usually created by applying World Range changes) and contains a World Range Weapon, Defense, or Sensor.
Close Attack: This is a risky maneuver consisting of a head-long run to close with a target vessel...
You may want to read a little more T5. It states a firm point weapon is half volume with a -1 to space range. Though the chart on Pg.80 indicated a -2 to range...T5 firmpoints can only mount World Range weapons that are undersized, i.e. generally range less than R=7 (50 km). We are talking about a 1-10 km or so...
As far as I know it has to be less than 1 Dt, so any negative range mod is enough for a turret (base 1 Dt) mount. B2 p53 also requires "and contains a World Range Weapon, Defense, or Sensor."You may want to read a little more T5. It states a firm point weapon is half volume with a -1 to space range.
T5 B2, p176:
FirmPoints. A hull may allocate, instead of HardPoints, three FirmPoints per 100 tons. A Firmpoint will accept any mount which is less than one ton (a full-ton mount does not fit on a FirmPoint).
?Though the chart on Pg.80 indicated a -2 to range...

The example from that section,As far as I know it has to be less than 1 Dt, so any negative range mod is enough for a turret (base 1 Dt) mount. B2 p53 also requires "and contains a World Range Weapon, Defense, or Sensor."
My latest says 5.1....Is there another edition I have missed?
Quite, and a Beam Laser is a World Range weapon with a default range of R=7 (50 km).The example from that section,
"For example, a Beam Laser-10 in a 1-ton turret has range R=7. Reducing the mount to R=6 also reduces the tonnage of the turret by half (to half-ton) and makes it eligible for a Firmpoint."

Yes, lasers are basically missile defences. The Navy isn't likely to count them as weapons at all.Hang on, are you saying T5 has reduced the range of laser weapons from lightseconds to 50km?
So beam attenuation has gone down the tubes, and the offensive weapons for ships are now railguns, missiles, particle beams and meson guns?Yes, lasers are basically missile defences. The Navy isn't likely to count them as weapons at all.
By using a larger, higher tech mount the range can be extended to R=10 (50 000 km).
