TT-9 was a Multi-Troop Transport in the Trade Federation Droid Army around 32 BBY.
TT-9 was designated as an auxiliary mobilization supply transport during the Invasion of Naboo, and coordinated with the orbital Droid Control Ship over Naboo to assign Single Trooper Aerial Platforms to particular areas of the occupation zone. TT-9 was conveyed to the planet's surface via a C-9979 landing craft, and almost ran down Qui-Gon Jinn and Jar Jar Binks as it drove through the forest close to Lake Paonga.
