Low-vulnerability component of explosive ammunition and process for initiating a charge of low-sensitivity composite explosive. The subject of the present invention is a low-vulnerability component of explosive ammunition consisting of a preferably metallic enclosure 1 containing a charge 2 of low-sensitivity composite explosive E and, as initiating relay, a plane wave generator 3 consisting, on the one hand, of a cylindroconical cap 7 made of composite explosive A, the large base surface having a diameter d greater than the critical diameter of the explosive E, the cavity 8 of this cap 7 being filled with a composite explosive B and, on the other hand, of a reinforcer made of composite explosive C, of thickness e greater than 0.1 d, the detonation pressure of the explosive C being higher than that of the explosive E. The detonability index according to the test for detonability behind a barrier is between 90 and 200 cards in the case of the explosives A, B and C and lower than 90 cards in the case of the explosive E. The invention also relates to the process for initiating the charge 2 using the generator 3.
