The Sundered Heart's added "fins" and extra engine compartments allowing the ship to move almost four times faster than the already incredible speed of the CR90 corvette. It also carried special equipment that allowed it to weaken enemy fire on command by creating an energy flux.
The ship had a very small hangar bay which could house one or two starfighters, depending on size. Obi-Wan Kenobi utilized this bay when he rendezvoused with the Sundered Heart after his battle with General Grievous.
The Sundered Heart, one of Bail Organa's personal vessels during the Clone Wars, as a CR70 corvette
During the time of the Clone Wars, Senator Bail Organa would use the Sundered Heart as his personal vessel, often utilizing it to travel from Coruscant to his homeworld, Alderaan. After witnessing firsthand the attack on the Jedi Temple by the 501st Legion, Senator Organa departed Coruscant in an attempt to rescue as many of the few survivors of the Jedi Purge as he could. Using a stolen Jedi Beacon, Organa was able to contact and rescue two of the last surviving members of the Jedi Council, Masters Obi-Wan Kenobi and Yoda, after escaping the Order 66 attacks on Utapau and Kashyyyk. He later took the Sundered Heart back to Coruscant so Yoda and Obi-Wan could alter a Homing beacon at the Jedi Temple, to keep the order safe. Bail Organa along with the other Republic Loyalist, were assigned to the Grand Convocation Chamber for the Declaration of a New Order.[1]
Afterward, Bail saved Yoda from a duel in the Chamber, after losing to Darth Sidious. Later, after the death of the Skywalker twin's mother on Polis Massa, the passengers and crew attended Padmé's Funeral on Naboo. After the funeral, it was aboard the Sundered Heart that the fates of Luke Skywalker and Leia Organa were decided. The House of Organa would adopt Leia on Alderaan, and the Lars family would adopt Luke on Tatooine. Yoda claimed to Obi-Wan that he had encountered the Force ghost of Qui-Gon Jinn, and said that he would be training Obi Wan in his exile, as well as Yoda himself. Bail then ordered C-3PO's memory to be erased by Captain Antilles, to make the locations of the Skywalker twins a secret. Yoda left the vessel for his self exile to Dagobah via his escape pod, Obi-Wan left as well for his self exile to Tatooine.[1] The droids R2-D2 and C-3PO were assigned to the ship at this point. Accompanying the droids R2-D2 and C-3PO on this fateful journey were Raymus Antilles and Jeremoch Colton.
At some point, the Heart was modified with the Vanguard c20 retrofit suite, converting from a CR70 corvette to a CR90, as well as adding a more powerful engine bank than standard.

Raymus Antilles received the ship as a gift for running aid and medical supplies past several Imperial blockades.[2]
The ship participated in the Battle of Kuat, where it destroyed six of the Imperial shipyards that orbited the planet in order to begin the operation of stealing the X-wing prototypes. She also rescued many Incom scientists as they were heading for the spice mines of Kessel. Then the ship participated in the battle of Atzerri.
During the battle over Tatooine, and since he was in an official task, Raymus piloted the Tantive IV, rather than the Heart. Raymus Antilles was killed and Tantive IV captured.
