Markalite Cannon

The Markalite Cannon is a powerful weapon that somewhat resembles a cross between a Radio Telescope and a satellite which appeared in the 1957 TOHO film The Mysterians. A single Markalite Cannon has caterpillar tracks which grants it limited maneveurability, although they could be transported and dropped by rockets called Markalite Gyros, a pair of which were attached to each Cannon. The weapons could only function for short periods of time before losing power, and several were lost in the battle against the Mysterians, but eventually they were able to destroy the alien's dome base and ultimately, win the battle.
