The Lupus-class missile frigate, also known as Trade Federation Missile Frigate, was a light frigate used by the Trade Federation prior to and during the Invasion of Naboo and by the CIS Navy early in the Clone Wars.
The Trade Federation Missile Frigate was a long, curve-hulled vessel with two pincer-like protrusions at the bow. It was armed with concussion missile launchers, and could launch between two and four missiles at a time. These missiles left orange-red trails and caused a large blast radius on impact. It was also armed with six anti-starfighter cannons, had a shield generator, and was hyperspace-capable.
The pirate captain Nym engaged several Missile Frigates in combat during his assaults against Trade Federation forces in the Karthakk system. These ships also participated in the blockade of Naboo.
They were in use during the Occupation of Karthakk. A blockade of Missile Frigates ambushed the Acclamator-class assault ship Aken during its approach to Geonosis prior to the outbreak of the Clone Wars in 22 BBY. With the aid of Adi Gallia and Siri Tachi, the Aken broke through the defensive line and reached the planet's surface.
Trade Federation Missile Frigates first appeared in the 2001 video game Star Wars: Starfighter.
