Pagination or Media Count:
A button-type, 50-millisecond delay primer, designated Primer, Electric XM88, was developed for incorporation in the PD, T212E6 and PD, XM566 Fuzes. Groups of primers were function tested at extreme and ambient temperatures after water immersion, environmental conditioning, ballistic firing and subjection to 30,000 Gs, with the primer contact pin forward and base forward. The development t fulfills the requirements for a delay initiator to be used in parallel with a superquick initiator, but the problem of sealing exists with the design of the plug assembly.
