Meson cannon

The Meson Cannon was a ship-mounted Sontaran weapon.

They were found on most Sontaran ships-of-the-line as a primary weapon. Ships that mounted Meson cannons included Linx class cruisers and Valt class destroyers.

Described as an open-ended particle accelerator using mesons, the cannons were available from at least 2370. (MA: Lords of the Storm)
