Transphasic torpedo

Transphasic torpedoes are powerful weapons from the future Federation.

Properties

Except for the obvious fact that they do a very good job of destroying Borg Cubes, these weapons remain an almost complete mystery. The name suggests that they defeat the frequency-specific shielding of Borg vessels by changing their own frequency or phase alignment.

Uniqueness

Transphasic torpedoes appear only in "Endgame", the final episode of Star Trek: Voyager. As yet, there is no indication that Starfleet "modern" starfleet was able to reproduce these futuristic weapons. As they were developed within the lifetime of Kathryn Janeway, the Federation should be capable of inventing them within a few decades.
