A "screen defense" was a starfighter combat tactic used by various fleets and squadrons to defend friendly assets during space battles by having the starfighters stay close to the capital ship and only firing on enemy ships that got too close, effectively forming a defensive screen around the capital ship, or parts of it.
The Battle of CoruscantEdit
The Thrawn CrisisEdit
During the Thrawn Crisis, New Republic Commander Wedge Antilles of Rogue Squadron devised a screen formation tactic allowing a minimum of fighters to protect a lightly defended spaceship. Forming an intricate "sphere" around the defended ship, the starfighters would regularly swap positions within the screen, forming a weaving pattern that made targeting any one vessel difficult.
