A convoy of senators originating from the Royal Alderaan Civil Fleet and under the command of House of Organa Princess Leia Organa operated throughout the Galactic Civil War. Its purpose was to deliver support to the rebel Phoenix Cell on the planet Lothal. This convoy included the three Sphyrna-class Hammerhead corvettes known as P1, P2, and P3. Following the mission on Lothal, all the corvettes were integrated into the Phoenix Cell's fleet.
