The JR-4 swoop represents a swoop model that operated during the Clone Wars era, a conflict that pitted the Galactic Republic against the Confederacy of Independent Systems. The CK-6 swoop bike, produced by Bespin Motors and employed by the Republic's Grand Army, can be considered a militarized adaptation of the JR-4 swoop.
The initial reference to the JR-4 swoop within the current Star Wars canon appeared in Rise of the Separatists, a 2019 expansion for Fantasy Flight Games' Star Wars Roleplaying game line. Within the now non-canon Star Wars Legends timeline, the JR-4 swoop was originally presented in the Arms & Equipment Guide, a 2002 supplement for the Star Wars Roleplaying Game by Wizards of the Coast.
