121 1 were a trio of Action VI transports used by the Rebel Alliance during the Galactic Civil War in 3 ABY.

The three transports were present at Vergesso Base during the Battle of the Bajic Shipyards when Darth Vader learned of the Rebel presence in the area, and launched a massive assault led by the Executor. In the assault, 121 1 attempted to flee the area, but flew right into the path of the Imperial Star Destroyers and came under heavy fire from the enemy. Despite a fierce resistance from Rebel pilots and Ace Azzameen on the Otana (Who was trying to rescue his sister Aeron from the shipyard), most if not all of 121 1 was destroyed in the battle.
