Nebulon-B Frigate

Luke Skywalker receives a prosthetic hand aboard the medical frigate Redemption at the conclusion of The Empire Strikes Back. A Nebulon-B medical frigate is part of the Rebel Alliance fleet at the Battle of Endor in Return of the Jedi.
 
Expanded Universe material states that relatively affordable Nebulon-B frigates, which are effective at engaging starfighters, are used by both the Rebellion and the Galactic Empire.
