The Borg cube was the primary starship class of the Borg Collective's fleet. Borg cubes are designed as a combined weapons platform and factory. Their main purpose was for destroying the military capacity of a species and assimilate the survivors into the Collective. Starfleet designated these ships as dreadnoughts. In the first few years after the were first encountered by the Federation, they were also known simply as a "Borg vessel." (Star Trek Encyclopedia, ST:CCG: First Contact, ST roleplay module: Starships, TNG video game: Echoes From the Past)



Borg Cubes were not constructed as such, but grown, in their own way being a lifeform within the collective. Prior to 2380 no Cube had ever been created outside the Delta Quadrant. Cubes could vary in size, but were typically large vessels; several kilometres in each dimension, up to the size of a small planet in exceptional circumstances. (TNG novel: Before Dishonor)



Like all Borg vessels, Borg Cubes operated in a completely decentralized manner with no bridge or engineering but duplicated systems all over the Cube so that theoretically even if as much as eighty percent of a Cube were destroyed it could continue to operate. In fact, Cubes did not even have a single unified hull but instead feature multiple forcefield projectors which are able to extend and contain the atmosphere in a Cube as necessary. The internal pressure aboard a Borg Cube was two kilopascals above what would be normal on a Federation starship, humidity was an average 92 percent, and temperature was at 39.1° Celsius. (TNG reference: The Collector's Edition #32; TNG movie: First Contact)

A Cube's decentralized systems included extensive weaponry; 36 programmable weapons arrays capable of producing phaser beams and torpedoes, 12 focused neutron beams capable of cutting through starships' hulls and 24 tractor beam emitters. Cubes are also equipped with 240 sensor arrays and a variety of propulsion systems, impulse engines, multiple warp field conduits capable of propelling the Cube in any direction at a cruising speed of warp 8 and top speed of warp 9.99 and multiple transwarp coils allowing the cube to enter and traverse the Borg's transwarp network. Earlier estimates by the Federation hinted at at least warp speeds of 9.9, allowing the vessels to travel 7,000 light years in one calendar year. (TNG reference: The Collector's Edition #32, TNG video game: Echoes From the Past)

The cubes also had an "unknown projection field" which was capable of blocking Starfleet transporters. (TNG video game: Echoes From the Past)

By 2377 the Collective had developed a way to join eight cubes together to form a single large vehicle called a Fusion cube. (TNG video game: Armada II)


Notable locations within a cube included a primary subprocessing matrix as well as an assimilation chamber. (VOY video game: Elite Force (game))


The collective began to use Cubes shortly after its creation and the Cube soon became the symbolic and feared icon of the collective. (ST short story: "The Beginning"; et al.)

In 2367 a single Cube was able to defeat a fleet of 39 Federation starships (TNG episode: "The Best of Both Worlds")

A Borg Cube came through the Bajoran wormhole in 2369. Fortunately, the wormhole was undergoing subspace compression at the time and destroyed the Cube. (DS9 novel: The Siege)

A unusual hybrid starship encountered by the USS Enterprise-D in 2370 included components from a Borg Cube. (TNG comic: "Strategy")

In 2380 remnants of the shattered Collective in the Alpha Quadrant created a massive new Cube, and grew a new Queen to command it on a mission to destroy humanity. This Cube was initially disabled, and the Queen destroyed by the crew of USS Enterprise-E. Unfortunately, the Cube was not as dead as it seemed, struggling for the survival of the collective it developed beyond anything any Cube had achieved before and independently planned to restore the collective. It assimilated Kathryn Janeway and made her its new Queen. It then prepared to attack Earth, absorbing, rather than the less efficient assimilation, anything that got in its way and anything it required. It very nearly succeeded, growing to a huge size and incredible power but was stopped by the efforts of the Enterprise crew and Seven of Nine. (TNG novels: Resistance, Before Dishonor)

Later, in 2381, several cubes launched bliztkrieg attacks into Federation space. This was deemed to be the starting point of the 2381 Borg Invasion. During the invasion, several cubes were destroyed by Federation and Klingon forces using Transphasic Torpedoes. Eventually, however, the Borg were able to adapt to the torpedoes and sent a force of 7000 cubes through the subspace tunnels in the Azure Nebula and into the Alpha Quadrant. Once there, the Borg armada decimated the allied fleet assembled at the nebula, leaving only USS Voyager intact.

The Borg cube is the primary vessel of the Borg Collective. Measuring 28 cubic kilometers in volume and carrying up to 200,000 Borg drones, the cube is one of the most powerful vessels in the galaxy. (VOY: "Dark Frontier")



The first Federation contact with a Borg cube took place in 2365, when the USS Enterprise-D encountered a single cube in System J-25. (TNG: "Q Who?")

Every Starfleet encounter with a single cube has resulted in heavy losses. 39 out of 40 ships were lost at the Battle of Wolf 359 in 2367, and dozens more in the incursion of 2373. (TNG: "The Drumhead"; DS9: "Emissary"; Star Trek: First Contact; Star Trek: The Prospect Chronicles: "The Burnt Child"; Star Trek: The Cantabrian Expeditions: "Catalyst, Part One", "An Innocent Time", "Devil's Cube") In the aftermath of the Battle of Wolf 359, an alien starship appeared to be communicating with the Borg cube en route to Earth. In actuality, it was a 27th century Federation starship communicating with their away team of historians aboard the cube; a communication the USS Prospect cut off, essentially leaving the historians to be assimilated. (Star Trek: The Prospect Chronicles: "The Burnt Child")

A single cube was capable of eliminating all elements of civilization from an entire planet.

When the USS Enterprise-D experienced malfunctions due to nanites in 2366, sensors erroneously detected an approaching cube. (TNG: "Evolution")

In 2372, the USS Cantabrian encountered a Borg cube, nicknaming it the "Devil's Cube", severely crippled in the Devil's Cradle by an unknown adversary. This adversary employed a harpoon-like system to breach the cube's hull and seriously cripple the cube. The cube was repaired and engaged the unknown adversary in a fierce fire-fight: one which the Cantabrian ran from. (Star Trek: The Cantabrian Expeditions: "Devil's Cube")

In late-2373, a second Borg cube was sent to assimilate Earth. The cube was detected after attacking the Federation colony of Ivor Prime. Starfleet intercepted the cube in the Typhon sector and engaged it in battle. The cube reached the Sol system before been destroyed by Starfleet forces led by the USS Enterprise-E. (Star Trek: First Contact)

In an alternate universe, the Borg cube sent in 2373 would place a crucial role by creating a turn point in the Federation Civil War. Its attack devastating Admiral James Leyton's forces defending Sector 001 and set in motion the final stages of that war. ('Star Trek: Pendragon)

Devil's Cube

The "Devil's Cube" was a Borg cube found drifting and heavily damaged in the Devil's Cradle by the USS Cantabrian in 2372. Ethan Arden gave it its nickname.

Upon closer inspection, the Cantabrian away team discovered several harpoon-like weapons lodged deep within the Devil's Cube. These weapons sent a surge through the cables attached, disabling the cube and its drones.

Cantabrian first officer Elizabeth Singh thought she discovered her daughter as a drone aboard the cube, but this hypothesis was disproven with a medical test.

The Cantabrian fled the attacking Devil's Cube after the cube's systems came back online, and the unknown adversary emerged again from a subspace rift. As the two alien ships battled, the Cantabrian made its escape, igniting metreon gas in its wake to either disable or destroy the enemy ships and collapse the subspace rift. (Star Trek: The Cantabrian Expeditions: "Devil's Cube")
