Thermobaric bombs

Thermobaric bombs, also referred to as Bombs were weapons that were briefly utilized in the 2017 Godzilla film, Godzilla: Planet of the Monsters.

Function
Thermobaric bombs within the Toho reboot series most likely work under the same conditions as real world weaponry.

Godzilla: Planet of the Monsters
Thermobaric bombs were mounted in landing ship bays and dropped into the path of Godzilla, in order to divert him to the ambush point sooner. Multiple bombs were dropped in front of the monster, surrounding him in fire, and while they failed to do any outright damage to him in spite of their tremendous power, they succeeded in diverting Godzilla's path.
