Sphyrna-class corvette

"Those are our reinforcements? Some old transports?''" "''In our position, you take what you can get, kid."

- Ezra Bridger and Kanan Jarrus

Hammerhead corvettes were a model of corvette used in the years leading up to and during the Galactic Civil War. The ships were inspired by a design that dated back centuries.

After learning of the rebellion's losses at the battle on Garel, Imperial senator Bail Organa of Alderaan dispatched his daughter, Princess Leia Organa, along with three Hammerhead corvettes &mdash; P1, P2 and P3 &mdash; to Lothal to expand the rebel fleet, under the guise of delivering relief supplies to the people of Lothal. The princess planned for the rebels to steal them to conceal Alderaan's involvement with the rebellion, but Lieutenant Yogar Lyste installed gravity locks to prevent the corvettes from taking off. With the help of former Lothal governor Ryder Azadi, who had constructed the locks while he was in prison, the rebels were able to commandeer the corvettes and add them to their growing fleet.

In 2 BBY, the former Sith Lord Maul assaulted one of the rebellion's corvettes. He interrogated the crew, leading to Maul capturing the Ghost personnel in order to unlock holocrons.

Later, Phoenix Squadron escorted one of their transports to evacuate rebel sympathizers at Mykapo in front of an imminent Imperial takeover.

Behind the scenes
Hammerhead corvettes first appeared in "A Princess on Lothal," the tenth episode of the second season of Star Wars Rebels, which also saw the introduction of Princess Leia Organa on the show. The ships are based on the Hammerhead-class cruisers from the now Legends video game Star Wars: Knights of the Old Republic.
