Attacking

Whenever one starship fires a weapon at another starship, that action is resolved with a gunnery check. Attacks are made during the gunnery phase of combat, in the order determined during the helm phase, but the damage and critical damage effects (see page 321) are applied after all of the attacks have been made (meaning every starship gets to attack, even if it would be destroyed or crippled by an attack that happened during the same gunnery phase). With only very rare exceptions, each of a starship’s weapons can be fired only once per round. You make an attack using the following procedure.

First, determine the range between the two starships (counted in hexes) and the arc of attack. For every range increment beyond the first, the gunnery check takes a cumulative –2 penalty. The attacking starship can fire a weapon against only ships in the same arc as that weapon; see the diagram on page 318. If the targeted starship is in a hex that lies in two arcs (the shaded hexes in the diagram), the gunner decides which arc’s weapons target it; it can’t be targeted by weapons in two arcs.

Attempt a gunnery check for each weapon fired against a target (except for linked weapons, which are resolved using one action and a single gunnery check; see the sidebar on page 301).

Gunnery Check = 1d20 + the gunner’s base attack bonus or the gunner’s ranks in the Piloting skill + the gunner’s Dexterity modifier + bonuses from computer systems + bonuses from the captain and science officers + range penalty

Compare the result of the gunnery check to the target’s Armor Class (AC) or Target Lock (TL), depending on the weapon used. If you attack with a direct-fire weapon (see page 303) and the result of the gunnery check equals or exceeds the target’s AC, you hit the target and damage is determined as normal (see Damage below). A target’s AC is determined using the following formula.

AC = 10 + the pilot’s ranks in the Piloting skill + the ship’s armor bonus + modifier based on the ship’s size + bonuses and penalties from successful or failed stunts and actions

If the attack is made with a tracking weapon such as a missile launcher (see page 303) and the result of the gunnery check equals or exceeds the target’s TL, the tracking weapon’s projectile moves its speed toward the target, making turns during this movement as needed (a projectile from a tracking weapon has perfect maneuverability). If it intercepts the target before it reaches the end of its movement, it explodes and deals damage as normal (see Damage below). If not, attempt a new gunnery check at the start of the next gunnery phase to determine whether the projectile continues to move toward the target; you don’t receive any bonuses from computer systems or actions by your fellow crew members from previous rounds or the current round, but you can take penalties, such as from an enemy science officer’s improve countermeasures action (see page 325). If the result of a gunnery check for a tracking weapon is ever less than the target’s TL, the weapon’s projectile is destroyed and removed from play. A target’s TL is determined using the following formula.

TL = 10 + the pilot’s ranks in the Piloting skill + the ship’s bonus from defensive countermeasures + modifier based on the ship’s size + penalty from the ship’s armor + bonuses and penalties from successful or failed stunts and actions
