Phage torpedo

The phage torpedo was a supposed form of torpedo developed by the Vidiians. Its namesake is the Vidiian disease known as the phage.

Reginald Barclay claimed the USS Voyager had phage torpedoes, along with Borg interquadratal warp drives and Hirogen hunting sensors, in order to trick the Ferengi into closing the geodesic fold in 2377.
