Species 10026 vessels were advanced starships utilized by Species 10026 during the latter half of the 24th century. These vessels were armed with modulating phaser pulses, which was considered by the Borg to be the vessel's tactical strength, as they were capable of penetrating Borg deflector shielding. The tactical weakness of these vessels was their lack of maneuverability.
Thirty-nine of these vessels engaged the two Borg cubes and Borg Queen's vessel that attempted to assimilate the Species 10026 homeworld in 2375. The Borg were able to adapt to these ship's weapons by triaxillating their shield geometry to absorb the phaser pulses, neutralizing the Species 10026 vessel's threat. (VOY: "Dark Frontier")
