These fuzes are designed for use on later model fire bombs. Electrically armed and impact fired, they are used in conjunction with FMU-7 series initiators and cable assemblies. Fuzes FMU-7/B and FMU-7A/B are interchangeable and similar except that the FMU-7A/B has a round head with metal tape under a hole in the center of the head. Two identical fuzes are used in each bomb in the nose and tail.
