Armament All calibres of smoothbore mortars. Development By Ecia for its own range of mortar bombs. Description A mechanical nose fuze providing super-quick action. Safety is ensured by a rotor which is locked in the rest position by a setback sleeve. On firing, this sleeve moves down and locks, leaving the rotor free. Because of its asymmetrical shape, as long as the bomb is under acceleration, the rotor will remain in the safe position. As soon as acceleration ceases, a spring causes it to revolve to the armed
position where it is locked in place with a detonator under the firing pin. On impact, the firing pin is driven into the detonator which then fires the fuze magazine. Manufacturer Esperanza y Cia.
