Stealth field generator

A stealth field generator is a device that apparently provides a cloaking shield over an area on a planet. The Space Pirates used one to conceal their operations in the Agon Wastes, which were just beginning. Aether, in the Dasha region, was on the fringe of Galactic Federation-controlled space.

Unfortunately for the Pirates, Dark Samus, in her raids on the Space Pirate mining facility for Phazon, crippled the generator. The Pirates feared detection by the Federation, although the one ship that was dispatched to Aether, the G.F.S. Tyr, lost its entire crew to Dark Splinters after crashing onto the planet. The Space Pirate starship it was pursuing also crashed, but the Pirates were able to salvage many things from the ship including a defense shield, and may have obtained a replacement generator as well.

It is possible that Dark Samus absorbed some of the generator's technology. During the real Samus Aran's second battle with her, Dark Samus' Logbook entry states that she has a stealth field generator in her armor, which she uses during the battle to render herself invisible to the Combat Visor. The Dark Visor is able to counter this technology. Further Phazon mutation later into the game enables Dark Samus to become invisible to the Dark Visor as well, though Samus can still track her through the Echo Visor.
