A full-round action requires an entire round to complete. If it doesnít involve moving any distance, a starship can combine it with a 500-foot shift. Jump To Cruising Speed
As a full-round action, a starship can leave the battlefield by jumping to cruising speed. Doing so effectively takes the ship out of the fight, although enemy ships can pursue the fleeing ship if they wish.
A starship cannot jump to cruising speed if it has 0 or fewer hit points.
Attacks of Opportunity: A starship that jumps to cruising speed provokes attacks of opportunity from threatening enemy ships armed with point-defense systems (see Starship Defense Systems).
A starship can use its afterburners to surge forward as a full-round action. When a starship surges forward, it can move up to four times its tactical speed in a straight line. (It does not get a 500-foot shift.) It loses its pilotís Dexterity bonus to Defense and any dodge bonuses to Defense since it canít avoid attacks.
A starship can surge forward for as many rounds as the pilot likes.
Attacks of Opportunity: A starship that surges forward provokes attacks of opportunity from threatening enemy ships armed with point-defense systems (see Starship Defense Systems).
Withdrawing from combat is a full-round action. When a starship withdraws, it can move up to twice its tactical speed. (It doesnít also get a 500-foot shift.) The square it starts from is not considered threatened for purposes of withdrawing, and therefore enemies with point-defense systems do not get attacks of opportunity against it when it moves from that square.
If, during the process of withdrawing, the starship moves through another threatened square (other than the one it started in) without stopping, enemies get attacks of opportunity as normal.
