Quantum Type: Quantum Torpedo Mark-QII. The quantum torpedo utilizes a zero-point energy reaction to create a 50+ isoton explosion. The technology is based upon an artificial quantum singularity engine core and similar weapons developed by the Romulan Star Empire, and the schematics were obtained by SI agents. The basic mechanism was originally experimented with in 2236. The first warhead application came 135 years later, in 2371. It was created as one of the weapons systems designed to fight the Borg. Indeed, quantum torpedoes were widely used by the Federation fleet when the Borg launched a second assault against Earth in early 2373. One ship that used these weapons was the USS Enterprise-E. There are two types of torpedo tubes created for launching this weapon: the pulse fire tube (1
