Insensitive munition

This invention relates to a novel insensitive munition (1) comprising one warhead and also munitions comprising one or more warheads (1). In particular, the invention lies in the field of insensitive munition warheads (1). There are further provided methods of preparing the warheads of the invention, methods of controllably detonating the warheads and a kit suitable for preparing such a warhead. The warhead (1) comprises at least two portions (3) of high explosive separated by a non-detonative material (8), wherein each portion (3) has a cross section below its critical detonation cross section, and wherein the at least two portions (3) are arranged such that the total cross section of the at least two portions (3) exceeds the critical detonation cross section of said high explosive, such that in use only simultaneous detonation of the at least two high explosives (3) causes detonation to occur.
