Cargo Bay 17 was a cargo bay on the Orca-class freighter, Freighter 2716. It contained prisoners captured by the Empire to help build the first Death Star.
In 1 BBY, Freighter 2716 was boarded by Saw Gerrera, Ezra Bridger, Sabine Wren, and Chopper. Accessing the ship's computer, they found that Cargo Bay 17 was a restricted area and decided to check it out. When they made it inside, they found it contained prisoners being transported to help construct the first Death Star, all of whom were reactor mechanics or power specialists of some kind. After freeing the prisoners, the rebels rigged a massive Kyber crystal to explode, which it did, promptly destroying Cargo Bay 17, along with the rest of Freighter 2716.
