- Not all large calibre AA shells are of that kind. The Swedish 40mm AA shell
- m/48 from Bofors does _not_ explode at a certain altitude, it explodes
- when the loss of rotation causes a couple of spring mounted balls to press
- the firing pin into the detonator (aprox after 7-8 sec fligth time) or by
- hitting something which causes the impact fuse to go off. The newer shells
- to the same gun wich has proximity fuses use a timer to cause selfdestruction
- after 7-8 secs.
-
- Since i have recieved e-mail after my last posting on this subject telling
- me I'm dead wrong, I shall soon post a detailed description of the Bofors
- 40mm AA prjectile.
