A gravimetric torpedo was a type of projectile weapon which could be created by outfitting a standard photon torpedo with a gravimetric charge. In theory, if a gravimetric torpedo were used to detonate a type-6 protostar, it could result in the formation of a wormhole. Seven of Nine was familiar with this technology.
In 2374, after having detected the presence of the Omega molecule in the Delta Quadrant, Kathryn Janeway, captain of the USS Voyager, ordered Lieutenant Commander Tuvok and Ensign Harry Kim to outfit a photon torpedo with a gravimetric charge with a yield of fifty-four isotons, to create a gravimetric torpedo with which to destroy the molecule, in accordance with the highly-classified Omega Directive. When further investigation revealed that there may have been hundreds of Omega molecules, however, Janeway ordered the yield increased to eighty isotons, which Harry Kim remarked to be enough to destroy a small planet. Eventually it was discovered that the amount of molecules was too great for even a torpedo to destroy, so Janeway had to resort to using a harmonic resonance chamber to destroy nearly fifty percent of the molecules, using the torpedo to destroy the rest.

The Borg use gravimetric torpedoes and was used by their vessels in combat against enemy ships. The weapon made use of advanced graviton inversion field to cause gravimetric shear in its target which causes severe structural damage. This made it perfect for an offensive role when the Borg have encountered a race that are resisting assimilation. (VOY: "Dark Frontier")
