Phaser dual heavy cannons.
A dual heavy cannon, usually referred to by as plural dual heavy cannons, was a cannon directed energy weapon emitter installed on starships and spaceborne-installations like starbases and other space stations. Commonly, dual heavy cannons would fire a pair of powerful bolts at the target. Compared to dual cannons, dual heavy cannons exhibited a slower firing rate but caused more damage per individual volley. (STO - Klingon War mission: "Welcome to Earth Spacedock")
History and specifics[]
Dual heavy cannons shared a 45° firing arc with dual cannons and quad cannons. In contrast, single cannons fired in a 180° arc. Cannons, dual cannons, dual heavy cannons, quad cannons and dual beam banks could not be installed in a ship's aft weapon emplacement. Another restriction was the ship type this weapon could be installed on. In starship classification, dual heavy cannons were restricted to these ship types: battlecruiser, carrier, destroyer, dreadnought cruiser, escort, frigate, strike wing escort, fighter, light cruiser, multi-mission science vessel, raider, raptor and warbird.

In the 25th century, the Khitomer Alliance differentiated between six basic damage types, and a plethora of variants. Phaser dual heavy cannons fired orange bolts that had, by default, a 2.5% change of disabling a target's subsystem. Lime-green disruptors had a similar chance of temporarily lowering the structural integrity field. Romulan and Borg ships could fitted with spring-green plasma dual heavy cannons. Alliance polaron dual heavy cannons fired purple, while those of the Dominion were pink or blue. Tetryon weapons, default for Hirogen Hierarchy ships, fired light blue; and antiproton arrays fired red.
