Gravity mines were a model of space mine used in space combat which used gravity based technology. They were designed to latch onto the hulls of starships and warp the local space around them in order to prevent them jumping to hyperspace before the mine could explode. Gravity mines were sold for 1,000 credits.
In the High Republic Era, Pan Eyta's Tempest used a gravity mine to pull the Tycoon Trader out of hyperspace in the Abrion sector in order to raid it.
Commodore Idel deployed a pair of gravity-based mines from his Star Destroyer when trying to capture the yacht Imperialis in the Castell system after it was stolen by the smuggler Lando Calrissian and a team of thieves. The mines were destroyed by the vessel's automated defense system before they could latch on.
