The Tachyon Star Bomb was designed to do just as its name describes: to cause the destruction of a star. In order to achieve this, the TSB would make use of a Skip, a very short form of faster-than-light travel, that would allow the bomb to enter into the core of the star from a nearby dispatch point. The bomb would then create several million tachyon parcels, packaging up the core (triggering a core collapse) and capturing around 80% of the star's total energy, before scattering it over several hundred light years.

The parcels themselves would travel at faster-than-light speeds, before the containers broke down and released the captured energy. The distance covered, as well as the resulting yield of each parcel, would be determined by the amount of energy available from the initial detonation of the bomb itself.

Once the containers had broken down, the energy they enclosed would be released into the immediate area. Nearby objects would be damaged by both heat and radiation.

The Tachyon Star Bombs were one of the major components of Operation Sudarberg. Five bombs were built, intended to be deployed in five key imperial star systems, hosting massive stars. The delivery system for each of the bombs was to be the ATAF, created specifically for the purpose. The bomblets created from the explosion of the star would be scattered throughout imperial space, eliminating the Pandoran forced based there.

The bombs were destroyed along with Grendel's Mother in late 2617, when the carrier was boarded and overrun by a number of Pandoran soldiers, who had invaded. The bombs captured the energy output of the ship, scattering it over a short distance and causing the raging between between the Pandoran army and the allied forces gathered in the Coyote system to be abandoned.

With no bombs remaining, Operation Sudarberg was officially a failure.
