Abstract
A safety and arming unit for a fuze of a projectile has a firing device for transferring the firing energy to another firing device and a barrier for interrupting the transfer. The barrier is locked in a locking state by a safety that triggers an unlocking action due to a physical arming parameter. The arming parameter of the novel device is an apogee parameter, effected by the projectile flying through the apogee of its projectile trajectory. A physical arming parameter independent of a launch parameter can be used to unlock the safety without needing to pull out a safety pin.
