Type 66 Maser Cannon

The Type 66 Maser Cannon (66式メーサー殺獣光線車 Rokuroku Shiki Mēsā Satsujū Kōsensha, lit. Type 66 Maser Beast Killer Beam Car) is a fictional weapon that first appeared in the 1966 Toho film The War of the Gargantuas. Originally developed as a missile interceptor system,[2] the Type 66 Maser Cannon was repurposed for use as an offensive weapon to combat the man-eating monster Gaira as part of "Operation L." Several of the weapons were used to assault Gaira, and nearly fatally wounded him until his "brother" Sanda arrived to rescue him. Once Sanda learned of his brother's true nature and the monsters began fighting in Tokyo, more Maser Cannons were deployed to open fire on Gaira. The Type 66 Maser Cannon was one of the first effective military weapons against a kaiju, and gave rise to many subsequent models across the differing continuities of the Godzilla series. In the Showa continuity, it was replaced with an improved model dubbed the Type 70 which saw action against Gigan and Megalon. In the Kiryu series continuity, the Type 66 was ultimately replaced with the upgraded Type 90.
