A separable ejectable protective nosecone for a guided munition comprises a munition body of cylindrical shape of longitudinal axis ZZ' having a munition body front end comprising a central part intended to be directed toward a target of the munition. The nosecone comprises, at the munition body front end and covering said front end, n contiguous nosecone portions of the same shape distributed about said longitudinal axis ZZ', one respective pyrotechnic device per nosecone portion. Each of the pyrotechnic devices comprises a pyrotechnic device body secured to the munition body, a pusher piston in contact with the respective nosecone portion. Simultaneous activation of the n pyrotechnic devices separates the edges of the nosecone portions from their respective plane of assembly in order to free the front end of the munition body. Application: Steered or guided munitions such as those of the rocket or projectile type or missiles.
