USS Enterprise vs. Malevolence

In July 2250, the Republic starship USS Enterprise encountered the massive warship Malevolence, a Subjugator-class heavy cruiser which had numerous turbolaser batteries and was equipped with a powerful ion cannon that could disable any spacecraft within its reach. The Enterprise itself was disabled by the effect and tractored by the battleship, but the crew eventually managed to restore the ship's systems in time and set off proton torpedo charges in the ion cannon, destroying the Malevolence.
