Separatist drop ships were a type of dropship utilized by the Confederacy of Independent Systems' navy throughout the Clone Wars. These vessels could penetrate through enemy picket lines, and they transported several squadrons of vulture droids. During the battle on Lokori in 19 BBY, multiple drop ships were deployed.
A Settie-class drop ship appears in Catalyst: A Rogue One Novel. It remains unclear if this drop ship is the same as the Settie-class drop ship or not.
