When does ship Evasive Action end?

According to the book, when doing ship-to-ship combat, every player gets an action each round (acting as the AI of the ship), and the enemy ships get a number of actions equal to their AI rating, and the Dodge action is replaced by Evasive Action. My understanding is that Dodge is maintained until the player’s next turn (or until the end of the next round if they don’t take an action for whatever reason). Does Evasive Action similarly last until the invoking player’s next turn or until the end of the round? The situation seemed a bit more fuzzy since it’s increased defense for all of the players in that case.
