Biography
R7-A7 was an astromech droid put into service during the Clone Wars. He was first assigned to the Delta-7B Aethersprite-class light interceptor piloted by Jedi padawan Ahsoka Tano on her first command mission during the Confederacy of Independent Systems' blockade of the planet Ryloth. Following the failure of the first phase of the mission, R7 was then integrated into a BTL-B Y-wing starfighter, also piloted by Tano, during the second phase of the attack on the blockade, when Ahsoka had to provide aerial support to General Anakin Skywalker's attack against a Lucrehulk-class battleship captained by the Neimoidian Mar Tuuk.
