Summary
The Borg Cube is a formidable ship that can destroy multiple Starfleet ships and assimilate their crew into the Borg Collective.
Other Borg ships, like the Borg Sphere and Borg Tactical Cube, possess distinct capabilities and present a formidable risk to Starfleet. The Singularity, the Borg Queen's vessel, is a highly advanced Borg ship that can create a rupture in the fabric of space-time, showcasing the evolutionary progress of the Borg within the Star Trek universe.
The Borg Cube stands out as one of the most iconic Star Trek ships ever created. However, throughout the franchise's history, there have been a few other noteworthy Borg ships. In "Q Who", an episode from season 2 of Star Trek: The Next Generation, the Borg Collective emerged as formidable foes, instilling fear in the hearts of the Federation for years to come. This was exemplified by the assimilation of Captain Jean-Luc Picard into the Borg Collective and the Battle of Wolf 359, which were pivotal moments that allowed TNG to break free from the limitations of Star Trek: The Original Series.
During the Battle of Wolf 359, a single Borg Cube was able to obliterate 39 Starfleet ships, solidifying the Borg as an immensely fearsome enemy. What made the Borg even more terrifying was their ability to strip away individuality and assimilate all uniqueness into their hive mind, transforming their victims into drones who shared a collective consciousness. Due to the immense power of the Borg Cube and the existential threat of assimilation, Star Trek did not need to make many alterations to their designs in order to maintain the timeless terror of these classic villains. Nonetheless, there have been a few exceptions to this convention throughout the various iterations of Star Trek.
8 Borg Cube (Various)
The most notable and formidable Borg vessel is the Borg Cube, which was first encountered by the USS Enterprise-D in season 2 of Star Trek: The Next Generation. During the distressing event at Wolf-359, the power of a single Borg Cube was demonstrated. However, in Star Trek: Voyager, it was revealed that "hundreds" of Borg Cubes would encircle a planet before obliterating it and assimilating its inhabitants. Within the interior of a Borg Cube resided thousands of Borg drones who possessed an inherent connection to the ship's systems. This allowed the drones to effectively command the Cube to repair itself, resulting in a formidable adversary in combat.
There have been instances where a Borg Cube managed to remain operational despite sustaining significant damage. This theory was proven by Commander Elizabeth Shelley (Elizabeth Dennehy) from Star Trek: The Next Generation when studying the Borg Queen's incapacitated Cube in season 3 of Star Trek: Picard. Additionally, Borg Cubes possessed the ability to traverse a network of transwarp conduits, enabling them to travel at much greater speeds than vessels equipped with Star Trek's traditional warp drive. In terms of weaponry, Borg Cubes housed immensely powerful tractor beams and cutting devices. These tools were utilized to immobilize other ships while the Borg initiated the assimilation process, incorporating both technology and crew members into their Collective.
7 Borg Sphere (Various)
The Borg Sphere, initially mistaken for an escape pod in Star Trek: First Contact, is in fact a fully-fledged ship used mainly for long-range reconnaissance and tactical purposes. While not as formidable as the Borg Cube, as proven by its destruction at the hands of the USS Enterprise-E when its shields were disabled, the Borg Sphere still possessed immense power. It was even capable of creating a temporal vortex, enabling it to travel back in time and endeavor to alter the course of Star Trek history by sabotaging the inaugural warp flight.
In the episode "Dark Frontier," Captain Kathryn Janeway (Kate Mulgrew) led a daring operation to pilfer a transwarp coil from a Borg Sphere. This episode was among the few instances in which the Borg Sphere made an appearance on the show. In the finale of Star Trek: Voyager, the USS Voyager found itself ensnared within a Borg sphere while utilizing a transwarp corridor to voyage home. However, Voyager managed to destroy the sphere from within, emerging victorious in the Alpha Quadrant and making a triumphant return to Earth.
6 Borg Scout Ship (Star Trek: TNG - I, Borg)
The Borg Sphere was introduced as a replacement for the Borg Scout Ship featured in the Star Trek: The Next Generation episode "I, Borg". In this episode, a team from the Enterprise discovered a lone Borg drone, later named Hugh (Jonathan del Arco), who was the sole survivor of the crashed Scout Ship. The structure depicted in the episode bears a resemblance to the Borg Cube previously seen in TNG, although it is noticeably smaller in size compared to the more formidable mother ship.
5 Borg Type 03 (Star Trek: TNG - Descent)
In the episode "Descent" of Star Trek: The Next Generation, the USS Enterprise-D, captained by Captain Picard, encounters a formidable ship labeled as Borg Type 03 within Starfleet. This vessel is operated by a rogue faction of Borg drones led by Lore, Data's malevolent brother portrayed by Brent Spiner. It remains uncertain whether Lore and his Borg comrades constructed the ship themselves or if they assimilated an existing entity. Regardless, the ship proves to be exceptionally powerful, causing the Enterprise to struggle in inflicting any significant damage during their direct confrontation. Eventually, under the command of acting Captain Doctor Beverly Crusher (played by Gates McFadden), the Enterprise successfully annihilates the Borg Type 03 through the clever utilization of a precisely timed solar fusion eruption.
4 Borg Probe (Star Trek: Voyager - Dark Frontier)
The Borg Probe ship, featured in the "Dark Frontier" episode of Star Trek: Voyager, made a singular appearance when it sought to intercept the USS Voyager. This unique vessel, described in the "Dark Frontier" script as "a never-before-seen geometric shape, significantly smaller than the average Borg ship – approximately half the size of Voyager," was originally considered as a potential substitute for the Borg Cube in Star Trek: First Contact, but ultimately faced rejection. Despite its smaller size compared to the USS Voyager, the Borg Probe was equipped with formidable weaponry, intended to rival the power of the Intrepid-class starship. To neutralize the threat, the crew of Voyager employed a strategy of transporting a photon torpedo on board the Borg Probe and triggering a detonation from within.
3 Borg Tactical Cube (Star Trek: Voyager - Unimatrix Zero)
The Borg Tactical Cube, featured in the Star Trek: Voyager two-parter "Unimatrix Zero," was an enhanced iteration of the standard Cube design. It boasted additional exterior armor plating and internally housed regenerating security fields, ensuring formidable protection against intruders. This heightened security was especially crucial as it accommodated Janeway, Lt. Commander Tuvok (Tim Russ), and Lt. B'Elanna Torres (Roxann Dawson), all of whom had been assimilated into the Borg Collective. These individuals daringly aimed to instigate dissent and incite a Borg Civil War. As a result of the uprising prompted by their efforts, the Borg Queen (Susanna Thompson) was compelled to initiate the self-destruction of the Tactical Cube.
2 The Borg Queen's Ship (Star Trek: Voyager)
1 The Singularity (Star Trek: Picard Season 2)
In Star Trek: Picard season 3, the ship in which the Borg Queen is hiding appears to be a partially destroyed Borg Cube, likely the one from the Star Trek: Voyager finale. However, "Dark Frontier" introduced a dedicated craft for the Borg Queen, an octahedron-shaped ship that provided enhanced protection with heavier armament compared to standard Borg Cubes. Additionally, it was accompanied by a guard of honor and often traveled with a group of Cubes. This particular ship only made an appearance in "Dark Frontier" when Seven of Nine (Jeri Ryan) was compelled to rejoin the Collective before being rescued by Janeway and the Delta Flyer. Eventually, Janeway managed to obliterate the Borg Queen's ship by collapsing the transwarp conduit it was traversing.
The remarkable Borg Singularity vessel made its debut in the second season of Star Trek: Picard, under the leadership of the more compassionate Borg Queen, Agnes Jurati (portrayed by Alison Pill). This particular Borg ship possessed exceptional power surpassing that of its contemporaries, partially owing to the dire state in which the Star Trek: Voyager finale had left the Collective. Nevertheless, its technologically advanced features were essentially attributed to Jurati's efforts in developing a more altruistic faction of the Borg since the year 2024, which took place after her entrapment in the penultimate episode of Picard's second season. A key highlight of this fresh Borg vessel was its ability to create a rift in the fabric of space-time to forewarn the Federation about a substantial transwarp corridor, although this significant aspect was largely disregarded in the third season of Star Trek: Picard. Considering the destruction of the Borg Queen's Cube in the third season, the Singularity may very well be the final addition to the Star Trek franchise's repertoire of new Borg ships.
