The 31st Flight represented a flight group of Confederate Navy Vulture-class droid starfighters that served the Confederacy of Independent Systems throughout the Clone Wars conflict.
The 31st Flight of the Confederate Navy consisted of Vulture-class battle droids painted in olive-green and tan-colored hues. Similar to the Vulture droids of the 28th Flight, these droids possessed enhanced defensive characteristics, but their weapon accuracy was lower compared to the droid starfighters found in the 72nd Flight or the 128th Flight.
During the Clone Wars, the 31st Flight group of starfighters saw action fighting for the Confederacy of Independent Systems.
A miniature representing the 31st Flight was included in the initial release of the Star Wars PocketModel TCG in June of 2007.
