Fuse for a projectile

A fuse for a projectile, comprising:

• a housing carrying first ignition means,
• a rotor mounted for rotation about an axis of rotation, said rotor comprising first and second legs spaced apart in a direction parallel to said axis of rotation to define a recess therebetween, said first leg carrying second ignition means, and said second leg carrying a detonator aligned with said second ignition means,
• means for rotating said rotor from a safety position in which said second ignition means and said detonator are non-aligned relative to said first ignition means to a live position in which said second ignition means and said detonator are aligned with said and first ignition means along an ignition axis, and
• means selectively providing ignition delay comprising
• a support carrying a retardation charge in a portion of said support, said support arranged such that said portion thereof is disposed within said recess so as to be protected by said first and second legs, means mounting said support for displacement within said recess between a first position in which said retardation charge is out of alignment with said ignition axis, and a second position in which said retardation charge is aligned with said ignition axis, and displacing means for displacing said support between said first and second positions.
