A shot-peen forming system includes a shot-sourcing chamber and a plurality of conduits, each having a first end and a second end. The first ends are coupled to the shot-sourcing chamber for receiving a portion of shot. A plurality of peen-forming jets are coupled to the second end of a respective one of the plurality of conduits. The plurality of jets are each adapted to fire shot in one of a plurality of predetermined directions to simultaneously deliver shot to a workpiece. An omnidirectional shot peening delivery system includes a plurality of nozzles positioned for shot peening from a plurality of angles, respectively. A shot distributor is adapted to receive shot through an inlet and distribute shot to the plurality of nozzles, and a workpiece holder is adapted to constrain a workpiece for receiving shot from the plurality of nozzles simultaneously to provide conformity during shot-peen forming.
