This chapter is a work in progress.
What I'd like here is a sort of mini-game, a game within the game. However, I want it to use the same basic game mechanics as normal character combat. It also needs some method of determining range bands without getting into measuring hexes or needing a battle mat -- in other words, no "facing", and no meter-by-meter (or megameter-by-megameter) movement.

Range Bands

There are five range bands: close, short, medium, long, and remote. Close range is the distance that a character can reach with their hands or with a hand-held weapon: anywhere from "in your face" up to about two meters. Short range is the distance that a character can easily reach with small hand-held weapons, or with thrown weapons with a bit of luck: up to ten meters. Medium range is too far for thrown weapons, but is within range of most small arms: up to fifty meters or so. Long range is too far for most handguns, but is within range of most rifles, with careful aim and a steady hand: up to 500 meters. A few weapons have even greater range, called "remote": these effectively have no maximum range.
Weapons and powers that are useful at a distance have an effective range given in their description. Due to the vast distances involved, attacking more distant targets is usually not possible. If the GM declares that the attack is possible, the attacker incurs an attack penalty (-3).

Close Grappling clamps, tractor beam

Short (10 km) Point defense laser

Medium (50 km) Laser battery

Long (500 km) Laser cannon, missile, plasma torpedo

Remote Planetary defense battery

If you'd prefer to emulate a setting more like Star Trek and less like Star Wars, multiply the weapon ranges by a factor of one thousand. So instead of short, medium and long ranges being 10 km, 50 km, and 500 km, they'd be 10,000 km, 50,000 km, and 500,000 km. (This doesn't actually make any difference in the game.)

Pursuit

Closing (or fleeing) would be an opposed Maneuverability roll. If both ships want to close (or flee), the roll is not opposed: instead it is treated as a "combining effort" on a challenging task (difficulty 3).
On a successful roll, the range between the ships decreases (if closing) or increases (if fleeing) by one range band. On an extreme success, the range increases (or decreases) an additional range band for each 3 that the winning ship rolled over the target number (one range band at 0-2, two range bands at 3-5, etc.).

In game terms, starships operate much like characters. Where characters have Brawn, Agility, Sensors, and Endurance, starships have Mass, Maneuverability, Sensors, and Integrity. Most starships also have armor or energy shields (some starships have both). Some starships have weapons, and a few have exotic equipment like tractor beams.

Armor

Armor provides protection against most forms of direct damage: anything which inflicts Integrity damage. The defense value (DV) of a starship with armor is equal to its Mass + 1, or the defense rating of the armor, whichever is greater. As always, this protection does not stack with energy shields or other forms of defense -- only the highest defense value applies.

Heavier armor restricts a starship's mobility. The effective Maneuverability of a starship with armor may be limited.

Defense Rating	Cost	Notes
1	400 KCr ✕ Mass	Maximum Maneuverability rank 8
2	800 KCr ✕ Mass	Maximum Maneuverability rank 7
3	1,600 KCr ✕ Mass	Maximum Maneuverability rank 6
4	2,000 KCr ✕ Mass	Maximum Maneuverability rank 5
5	4,000 KCr ✕ Mass	Maximum Maneuverability rank 4
6	8,000 KCr ✕ Mass	Maximum Maneuverability rank 3

Energy Shields

Energy shields provide protection against most forms of direct damage: anything which inflicts Integrity damage. The defense value (DV) of a starship with an energy shield is equal to its Mass + 1, or the defense rating of the energy shield, whichever is greater. As always, this protection does not stack with armor or other forms of defense -- only the highest defense value applies.

Shields which are stronger also generate more electromagnetic interference. The effective Sensors of a starship using an energy shield may be limited.

2	3,200 KCr ✕ Mass	Maximum Sensors rank 7

Short Range Weapons

XXX WORKING

Short range weapons are typically useful up to a distance of 10 kilometers. The attack value (AV) of a starship using a ranged weapon is usually equal to its relevant attack attribute (typically Maneuverability) + 1, or the attack rating of the weapon, whichever is greater.

Medium Range Weapons

Medium range weapons are typically useful up to a distance of 50 kilometers. The attack value (AV) of a starship using a ranged weapon is usually equal to its relevant attack attribute (typically Maneuverability) + 1, or the attack rating of the weapon, whichever is greater.

A Note On Repeating Weapons

Weapons which fire multiple rounds, such as turbolasers and MIRV torpedoes, usually grant an attack bonus (+3), and they might or might not do more damage than their single-shot equivalents (AR 4 instead of AR 3, for example), but the attack is only resolved once. Whether the damage from an attack is inflicted by one discrete injury or twelve, it's all just one attack roll. There's no "roll damage three times" mechanic like some game systems have.
