The Mk III Bridge was briefly mentioned in a scan in Metroid Prime 2: Echoes. The Logbook entry for the Mk II Bridge stated that the Mk III would "enter service within the next eight cycles." It would have, at the very least, fixed the locking mechanism failure that is present in the current design. However, all members of the GFMC Task Force Herakles were killed before the design presumably was created. It is possible that it is now being used following the liberation of Aether, by the Galactic Federation.
