Meson cannon

Meson cannons were ship-mounted Sontaran weapons.

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. (PROSE: Lords of the Storm)

One Sontaran once carried a similar type of weapon. (HOMEVID: A Fix with Sontarans)
