Transphasic torpedo

The transphasic torpedo was a very powerful weapon brought back in time from the early 25th century by Admiral Janeway. These torpedoes were designed specifically for use against the Borg and a single transphasic torpedo is capable of destroying a Borg Cube.

In 2381, the USS Enterprise-E had been fitted with transphasic torpedos. During the Borg sieges in February of this year, Captain Jean-Luc Picard recomended that the whole fleet be outfitted with the devices, to give the fleet a better chance of survival. He was over-ruled by Admiral Alynna Nechayev, who feared that the more the weapons were used, the more opportunity it gave the Borg to adapt.
