Description

This fuze is an all transistorized, continuous wave, doppler device to provide airburst characteristics. It was designed primarily for use with HE warheads for improved anti-personnel effectiveness.

A super-quick impact switch serves as a backup in the event of failure of the airburst electronics. The arming mechanism is similar to that contained in the M423/M427 Fuze except that it has been modified to include an electric detonator as well as a battery starter assembly to initiate an electric battery. An electric detonator is assembled in the rotor. A plastic (lexan) sleeve houses the thermal battery which is located directly above the safety and arming device.
