Magnetising cluster bombs, also known as magnetic cluster bombs, were explosive weapons carried by bomber craft such as the Rebel Alliance's Y-wings during the Galactic Civil War. The bombs were spherical in appearance and were able to be magnetized, which allowed them to attach to the metallic hulls of heavily armored vehicles such as All Terrain Armored Transports and produce great damage when released in vast numbers.
Magnetising cluster bombs first appeared in the comic book Shattered Empire 2, which was written by Greg Rucka and published by Marvel Comics on October 7, 2015. They were later identified in Star Wars Helmet Collection 26, a magazine published by De Agostini in 2016.
