Description:
Naval guns have been firing unexploding cannonballs. A time-delay mechanism invented by the French navy now allows exploding shells to be fired safely by high-powered, flat trajectory guns. The navies of Britain, the United States and Russia will have such guns before the decade ends.Ajouté au bande de temps:
