Tricobalt Device

Notes

Universe Name :	Prime Timeline
Weapon Name :	Tricobalt Device1

The tri-cobalt warhead is a high yield device used for destruction of large scale stationary targets such as space stations.1 Several species have deployed this technology at some time; one notable example is the planets Eminiar VII and Vendikar, who used computer simulations of tri-cobalt devices as part of their simulated war. The USS Enterprise was declared a casualty of one of these devices when it failed to raise its shields during a simulated attack by Vendikar, a situation which brought a rather determined response from the commanding officer.2

Although the Federation is banned from using subspace weapons by the Khittomer accords3, Starfleet vessels do carry tri-cobalt devices occasionally. In 2371 the USS Voyager used two of them to destroy the Caretaker's array in order to prevent it from falling into the hands of the Kazon.1 The Starfleet weapon has a programmable yield which can reach 20,000 Teracochranes, more than enough to destroy even a large station like the Caretaker's array.4

Detonating tri-cobalt devices within high gravity fields such as those found near to dead stars can create pockets of interphase space. These can form gateways between parallel dimensions5, though such gateways can be highly unstable and are easily disrupted by energy releases.6
