Regenerative bio-steel is a material that uses internal nanobots to slowly repair hull damage. However, the rate of repair is much slower than that carried out by SCVs. Science vessels modified by Egon Stetmann during the Second Great War were able to utilize nanites in order to repair allied vehicles.
Simulantcorruptors were equipped with self-replicating nanites that were programmed to function identically to the zerg corruptor's spores.
During their ceasefire, the Terran Dominion came into possession of a number of protoss nanites through illicit means. These were utilized by the Dominion Special Forces in their tech labs to improve energy output and research speed.
