The Trade Federation Defense Fleet was the corporate fleet of the Trade Defense Force.
The defense fleet consisted of capital ships such as heavy munition cruisers and missile frigates. They made heavy use of droid crew, including OOM pilot battle droids, infantry battle droids of various types, and droid starfighters, but they also carried cadres of sentient personnel, often humans, including their commanders and TDF officers, and other personnel such as scout pilots and companies of troops.
After the Invasion of Naboo, the Trade Federation was forced to hand over warships to the Galactic Republic's Judicial Forces, leading to Federation ships and crews serving in the Republic-led Second Battle of Zonama Sekot.
In the years before the Clone Wars, the Trade Federation subsequently regained a military force, including missile frigates of pre-Naboo design which fought in a picket role at the First Battle of Geonosis, and large new cruiser and destroyer designs using Lucrehulk-class core ships as command modules.
The Trade Federation Defense Fleet plays an important role in Rogue Planet, where it is implied that it traditionally provided the military protection for Trade Federation cargo haulers. In Cloak of Deception, however, no mention made of the separate defense fleet, and the LH-3210 freighters Revenue and Acquisitor are depicted as armed, shielded, and protected by their own battle droids and starfighters in the period before the invasion of Naboo. It was the captain of one of these armed freighters, Daultay Dofine, who went on to command the invasion fleet at Naboo.
