Isolytic burst Son'a vessels carried and used isolytic burst weapons, a type of subspace weapon. They were seen using this weapon against the Enterprise-E in Star Trek: Insurrection. The Enterprise was only able to escape the weapon's effect by ejecting its warp core and detonating it to seal a subspace rift. Tricobalt devices The tricobalt warhead is a subspace weapon whose high-yield detonations can tear holes in subspace. Tricobalt devices are not a standard armament of Federation vessels and yields are calculated in Tera-Cochranes, indicating that its mechanism is somewhat similar to the general reaction in a warp field. In TOS: "A Taste of Armageddon", the Eminian Union classified the USS Enterprise as 'destroyed' when it was hit by virtual tricobalt satellites. In DS9: "Trials and Tribble-ations", Arne Darvin plants a tricobalt explosive in a dead Tribble in an attempt to kill Kirk. USS Voyager uses a pair of tricobalt devices to destroy the Caretaker array in the Star Trek: Voyager pilot episode, "Caretaker", and such a device was used against Voyager in the episode "Blink of an Eye". A tricobalt warhead was also used by the Tholians in the Star Trek: Enterprise episode "In a Mirror, Darkly". They detonated a tricobalt warhead inside the gravity well of a dead star. The explosion created an interphasic rift, which they used to lure the Federation starship USS Defiant from another universe. The games Star Trek: Armada and Star Trek: Armada II have ships armed with Tricobalt devices for artillery support. The Federation Steamrunner-class, the Klingon Chuq'Beh-class Bird of Prey, the Romulan Raptor-class Warbird, and the Borg Harbinger are all capable of using them. The workings of the weapon is unknown but theorised is the use of Cobalt-60. It is far more likely that tricobalt refers to the third periodical table analog for cobalt; similar to dilithium being the second periodic table equivalent of regular lithium. "trititanium" and most other in trek universe usage where a numeric prefix is appended to a regular real world periodic table element refers to additional periodic tables whose elements are composed of nucleons that are not protons or neutrons and maybe not even regular electrons yet can form atoms molecules and chemical compounds similar to normal matter. Neutron radiation such as produced by a Cobalt 60 weapon is not very useful for destroying outposts, starships or anything else that is not a living creature. Other weapons
