the data tapes Princess Leia Organa, a secret Rebel leader, hid the data tapes in the memory banks of R2-D2, and the astromech jettisoned the ship with C-3PO.

We all know the opening scenes of Star Wars Episode IV, where the Rebel ship is captured, and Princess Leia places the Death Star plans into R2-D2's memory banks.

Princess Leia Organa was one of the greatest leaders of the Rebel Alliance, fearless on the battlefield and dedicated to ending the Empire's tyranny.

Artoo-Detoo R2-D2 (/ˌɑːr.tuːˈdiːtuː/) or Artoo-Detoo is a fictional robot character in the Star Wars franchise created by George Lucas. He has appeared in ten of the eleven theatrical Star Wars films to date, including every movie in the orginal trilogy, prequel trilogy, and sequel trilogy.

Theres a weird misconception that R2 had his memory wiped as well, he didnt. He knows everything and everyone that was a part of The Skywalker Story. He just never said anything to protect luke and leia. He was there at Leia's birth and he was there at her Death.

Leia Organa-Skywalker Leia Organa-Skywalker Leia Amidala Skywalker (portrayed by Carrie Fisher) is the wife of Han Solo, the mother of Ben Solo, the younger twin sister of Luke Skywalker, the daughter of Anakin Skywalker and Padmé Amidala, and the granddaughter of Shmi Skywalker, raised by Bail and Breha Organa of Alderaan.

Luke's sister Leia had three children. Her youngest son Anakin died at an early age, sending his sister Jaina nearly over to the dark side, before she came back from the edge of darkness.

A replacement droid assigned to Anakin Skywalker during the Clone Wars after the loss of R2-D2, R3-S6 was a newer model at the time, the latest in astromech technology.

Star Wars Theory: R2-D2 Didn't Know Anakin Skywalker Became Darth Vader. R2-D2 served Queen Amidala and later Anakin Skywalker, accompanied by C-3PO. Unlike the golden protocol droid, R2-D2 never had a full memory wipe, so he was well aware of all events that happened around him.

While droids do not have genders, they can have gender specific programming, such as protocol droids with male or female voices. As for everyone's favorite blue astro-droid, R2-D2 is always referred to as “he” by C-3PO, indicating male programming.
