Targeting beacon

A targeting beacon was a device that allowed starships to bomb a location regardless of the weather conditions. In 3,641 BBY during the battle of Kalandis Seven Colonel Jace Malcom gave a satchel of targeting beacons to Sergeant Shanra Immel, which she planted on the local spaceport to enable Republic fighters to bomb it.

Targeting beacons first appeared in Alexander Freed's short story The Last Battle of Colonel Jace Malcom which was published in Star Wars Insider 137 and released on October 23, 2012.
