A Tesla Cannon found mounted underneath an Annihilation Barge
A Tesla Cannon is a form of Necron Tesla Weapon that unleashes a bolt of living lightning that crackles from foe to foe after hitting its target, charring flesh and melting armour. Tesla bolts feed off the energy released by the destruction, and the lightning discharge becomes more furious with every fresh arc, almost as if moving with a mind of its own. In some cases, these energetic projectiles have even been observed to crack ceramite and plasteel. These weapons have been named by the Imperium after the ancient Terran scientist Nikola Tesla, who was the first human known to experiment with this type of weapon technology, although the Necrons had perfected it long before humans even existed. A Tesla Cannon is a large Tesla Weapon only found mounted as a secondary weapon underneath Catacomb Command Barges and Annihilation Barges. Tesseract Arks are also able to mount two Tesla Cannons as secondary weapon systems. Tesla Cannons are powerful weapons that are most effective against infantry squads and light vehicles.
