Grubstake was a civilian supply vessel that was active during the era of the Mandalorian Wars between the Galactic Republic and the Mandalorian warrior clans. In 3963 BBY, Grubstake was one of the fringer supply ships on the planet Serroco when it came under attack by Mandalorians—the invaders devastated the planet's surface with nuclear missiles, and Grubstake was destroyed in the fighting. Grubstake's destruction was noted in an edition of The Admiral's List, an official publication issued by the Republic Navy, along with another fringer vessel, the Little Bivoli.
