The gravitic harmonic resonator cannon was a ship-mounted weapon that was another showcase of Gorn expertise in tractor beam technology.
History and specifications[]
For use, the weapon needed a tractor lock on an enemy starship where it would use gravity to both attract and repel the enemy ship at the same time. This would continue until the enemy ship was fractured and ripped apart, making it particularly brutal. (ST video game: Klingon Academy)
