A concussive charge was an explosive weapon utilized by both Starfleet and the Klingons.

In 2293, a Klingon battle cruiser fired concussive charges off the bow of the USS Excelsior, as the latter vessel was attempting to infiltrate Klingon space through the Azure Nebula. (VOY: "Flashback")

In 2368, Commander William Riker, first officer of the USS Enterprise, suggested using a concussive charge to blow out the security fields which had been erected around Ten Forward by Ux-Mal criminals, who had taken over the bodies of Lieutenant Commander Data, Counselor Troi, and Chief O'Brien.
