Black Box

A Black Box, also known as a Fax Machine or K-series transmitter, is a special type of faster-than-light communications device, operating through the same hyperspace medium used by Jump Drives and hyperpulse generators. Initially discovered by the Star League, it would be rediscovered by Archon Katrina Steiner, her lover Duke Arthur Luvon of Donegal, and Morgan Kell of the Kell Hounds mercenary unit. Black boxes would become a critical means of communication for the Lyran Commonwealth and its allies, but began suffering severe technical problems in the 3140s.


Black Boxes were first proposed to the SLDF Communications Command in 2572 as an alternative to the "Pony Express" system of communications then in use. Developed under the codename Project TRANSIENT, prototype units were delivered in 2580 to the SLDF's Rim Worlds commanders during the Reunification War. The devices were able to pass small amounts of data (~200 kilobytes), usually inputted in a fax-type manner,[1] to other Black Boxes within a hundred light years. The relatively fast speed, compared with the common transmission per JumpShip, and the small size of the messages relegated them only to the most important traffic. But after years of development on a small budget, Project TRANSIENT was terminated in 2614 and following the appearance of the much more capable hyperpulse generator in 2630 the SLDF Communications Command ordered all the Black Boxes collected and dismantled, but until then all worlds of the Star League received an exemplar.[1] The official reasons given for dismantlement were that Black Boxes would interfere with HPGs and K-F Drives, reasons that were later disproven. Circa 3150, Dr. Melir Radis raised the possibility, based on Star League records, that Black Box cross-interference led to their abandonment.[2] At least one device survived into the thirty-first century.[3]

General Aleksandr Kerensky and the SLDF took several faxes with him in Operation EXODUS, and one was provided to an operative placed on the SLS Hermes during the Prinz Eugen Mutiny.[4]

How Katrina Steiner came to discover this technology is unknown, but when she returned from the Periphery after her one-year disappearance in 3005 she brought back an example.[5] (More recent speculation is that Katrina and her companions stumbled across the device in the remains of the SLDF Seventeenth Royal Division's headquarters on Taran's World. This facility was struck by a dirty bomb and SLDF engineers simply bulldozed the site and buried it in ferrocrete.)[3]

When the Lyrans allied with the Federated Suns to form the Federated Commonwealth in 3020, one of the secrets shared with the Suns was the existence of the black box technology. Working in conjunction with the New Avalon Institute of Science, the Department of Military Communications and Research was born, and in November 3027 demonstrated the use of the black boxes for military communication. Within months the Department was distributing dozens of black boxes to military commands throughout the AFFS and LCAF. Black boxes would prove instrumental in the Fourth Succession War, especially when ComStar instituted a communications blackout within FedCom territory on false pretenses.[5]

However, during the war the Draconis Combine was able to recover several black boxes, and would use them during the War of 3039. While not completely lax in their encryption protocols, neither the Lyrans nor Suns believed that the Combine had access to their technology, and so many of their messages were intercepted and used against them during the war.[5] ComStar also became aware of the black box technology, and stepped up efforts to target members of the Department of Military Communications.[6] Realizing that their enemies had access to their technology, FedCom redoubled their efforts to encrypt their transmissions, though it would not be until 3051 during the Clan Invasion that the Combine formally revealed its own possession of black boxes.[5]

Black Boxes were used by Interstellar Expeditions who possessed a few dozen of the devices, and Brooklyn Stevens who misappropriated one from them.[7]

The Umayyad Caliphate and Nueva Castile both possessed at least two each of the K-0 or 1 series devices (described as not encrypted) but just prior to the Jihad they were all stolen.[8]

Black Boxes were not directly affected by the events of August 7, 3132. However, their increasing use after the Blackout came with growing problems of redirected, garbled, and de-encrypted messages, which became regular occurrences by 3147. Dr. Melir Radis theorized that Black Boxes created ripples and waves across their limited hyperspace frequency, interfering with each other and making the transmission of any message a gamble. He discovered Star League research indicating the same problems occurred in their time, with data indicating that the ripples could take over a century to dissipate.[2]


Unlike an HPG, a black box radiates a signal that propagates outward through hyperspace, like ripples in a pond. However, it was believed by Star League scientists that this phenomenon would interfere with the workings of jump drives and HPG transmitters. These black boxes, while only the size of a briefcase and so much more portable, could not compare to HPGs in terms of speed or size of message that could be transmitted, which prompted their initial abandonment.[5]

When rediscovered and adopted by FedCom, all black boxes were fitted with a self-destruct and tracking device. These safeguards were assumed to be enough to prevent their misuse, however the events of the War of 3039 would prove otherwise. Since its adoption, a number of different black box models have produced.[5]

K-0 Series[edit]

The original black box from 2580, these devices could send a message no more than two hundred kilobytes of data at roughly ten light-years a day, with a maximum range of a hundred light-years.[9][3]

K-1 Series[edit]

The first FedCom improved production model from 3027, it was implemented and used during the Fourth Succession War. It increased the speed and range to twenty-five light-years per day and two hundred light-years respectively.[9]

K-1A Series[edit]

Introduced in 3035, the K-1A improved the device's range to four hundred and fifty light-years.[9]

K-1B Series[edit]

As the first Draconis Combine built model, the K-1B, from 3041, has a range of two hundred and fifty light-years.[9]

K-2 Series[edit]

The K-2 was introduced in 3042, improving message speed to fifty light-years per day and including a hardwired encryption feature, a result of DCMS eavesdropping.[9]

K-3 Series[edit]

The K-3 was introduced in 3044, increased range to five hundred light-years, and is the first model with dual-channel capability.[9]

K-3A Series[edit]

The K-3A is the second Draconis Combine built model, and has similar capabilities to the K-3. It was introduced in 3052.[9]

K-4 Series[edit]

A true revolution in black box technology, the K-4 was introduced in 3048 and increased message speeds to one hundred light-years per day with a range of six hundred light-years. It also increases the size of the data packet that can be sent, allowing four megabytes of data to be transmitted.[9]

K-5 Series[edit]

Introduced in 3054, K-5 black boxes have a range of eight hundred light-years, with a propagation speed of one hundred and fifty light-years per day. It can send up to thirty-five pages of text, and have a capability to handle four channels.[9]

K-6 Series[edit]

Introduced in 3061, K-6 black boxes have a range of one thousand two hundred light-years, with a propagation speed of one hundred and eighty light-years per day. It can send up to fifty pages of text, and have a capability to handle nine channels.[9]


During the Dark Age, only the Federated Suns, Lyran Commonwealth and Republic of the Sphere states (and, to a lesser extent, the Draconis Combine) possessed the Black Box technology; ComStar did not appear to have it.
