A compact device known as a fusion disk incorporated a small explosive charge. Upon impact with a surface, this charge would detonate, effectively welding the disk to any metal it touched. These fusion disks were integral to the functionality of power harpoon launchers, enabling tugs and airspeeders to connect to cargo modules and skiffs.
A strategy involving fusion disks affixed to tow cables was conceived by Commander Beryl Chiffonage and subsequently employed by the Rebel Alliance to disable All Terrain Armored Transports.
