According to an aspect of the invention, there is provided a fuze arming system for a submunition, comprising: a first stage, arranged to detect launch of the submunition and its associated carrier; a second stage, arranged to detect expulsion of the submunition from the carrier, and to at least partially arm a submunition fuze based on such detection; wherein the second stage is unable to at least partially arm the submunition fuze without the first stage detecting launch of the submunition and its associated carrier.

According to an aspect of the invention, there is provided a fuze arming system for a submunition, comprising: a first stage, arranged to detect launch of the submunition and its associated carrier; a second stage, arranged to detect expulsion of the submunition from the carrier, and to at least partially arm a submunition fuze based on such detection; wherein the second stage is unable to at least partially arm the submunition fuze without the first stage detecting launch of the submunition and its associated carrier.

A mounting device that is used to suspend items in a specific location inside the cavity of a tubular structure, such as a munition, is disclosed. The mounting device includes: a pedestal for leading the insertion of the mounting device into a cavity of a munition and a skeletal frame. The skeletal frame defines an opening therein for holding an article inside the outermost portion of the skeletal frame. In some cases, the skeletal frame may have a fixed configuration. In other cases, the skeletal frame may be collapsible and expandable so that it may be inserted into a cavity of a munition having an obstruction therein. Methods of inserting and mounting an article inside an internal explosive cavity of a munition are also disclosed.

According to an aspect of the invention, there is provided a method of triggering an explosive charge of each of a plurality of munitions, the method comprising: launching a first munition, into the air, from a first gun barrel, and into water to engage with a target location, the first munition comprising a first explosive charge and a first fuze system, adapted to trigger the first explosive charge in the water, launching a second munition, into the air, from a second gun barrel, and into water to engage with the target location, the second munition comprising an second explosive charge and a second fuze system, adapted to trigger the second explosive charge in the water, the method comprising co-ordinating the timing of the triggering of the first explosive charge and the second explosive charge to establish a co-ordinated explosive event at the target location.
