General

Because rocket ballistics have something in common with the ballistics of both projec-tiles and bombs, their fuze design has borrowed from both of these, and has also initia-ted devices from its own province, such as using motor gas pressure to arm base fuzes, etc.

The development of rockets during the war was rapid, and adaptations were someti-mes thrown into the breech which will now be replaced by more efficient mechanisms. At present, however, there is a great variety of rocket fuzes available.

Dummy fuzes

The Army uses inert or dummy fuzes in its practice rounds. They are designated by different numbers than those on their corresponding service fuzes.
